The main emphasis of our lab is in conducting clinical and translational research dedicated to preserving the health and independence of older adults. Broadly, our work centers around identifying factors which contribute to the onset of age-related physical disability and subsequently identifying novel interventions to rehabilitate older adults with functional impairments and prevent disablement. We strive to work collaboratively to conduct high-quality studies in an attempt to improve quality of life for older adults. Integral to our work are the principles of exercise and skeletal muscle physiology, yet we also incorporate a variety of other discplines – including pharmacology, genetics, and cardiovascular physiology. Currently, we are 1) investigating sources of heterogeneity (independent of adherence) in older adults’ functional responses to exercise, and 2) seeking to identify novel adjuvant therapies or alternative paradigms to improve the efficacy of physical exercise for improving functional status among older adults.

My work is in two main areas of aging research. First, my work focuses on how personality contributes to successful aging and psychological well-being in old age. In this area, I have conducted studies on adults’ coping strategies, their self-concept, and on the connections between personality traits and the pursuit of personal goals in everyday life. Recently, I have also started to focus on adults’ cognitive representations of their illness as a factor in adaptation to chronic illness. Second, I conduct work in the area of applied cognitive research. Specifically, I am interested in the cognitive abilities that influence older adults’ medication taking behavior and their adherence or non-adherence to their medication regimen. In addition, I am interested in how older adults’ beliefs in their own efficacy can be used in training programs to alter their fear of falling.

Seeking highly qualified candidates to complement a National Institutes of Health (NIH) funded project investigating how aging changes the way people use energy to perform common daily activities. The primary purpose of this study is to determine the age-related differences in the metabolic cost of daily activities. A secondary purpose of this project is to validate wearable technology to estimate people’s energy use. In addition to this project, the successful candidate will have the opportunity to conduct studies on reducing sedentary behavior (e.g. television viewing time) among older adults. Previous scholars in our laboratory have had tremendous success and have gone on to work at the NIH and/or were admitted into nationally recognized medical schools.

The specific project we’re looking for colleagues for concerns the assessment of neuropsychological functioning, and day-to-day consistency of performance, in older adults with and without dementia. We’re interested in whether “inconsistency” (daily variability) of cognition might be an independent diagnostic of impaired cognitive functioning. More broadly, from my website: older adults’ everyday problem solving abilities, their relationship to basic cognitive and intellectual performance and to functional competence, and the role of social partners in cognitive collaboration the range of modifiability (plasticity) in adults’ intellectual functioning, and antecedents (especially sensorimotor) of individual differences in adult cognitive and intellectual functioning.

Hearing loss is caused by genetic defects, noise exposure, ototoxic drugs, and/or aging and is the third most prevalent chronic health condition in adults. A major question being studied in our laboratory is how hearing deteriorates with age at the molecular level. We are particularly interested in understanding how cochlear hair cells, spiral ganglion neurons, and/or stria vascularis cells are continually lost throughout life. To answer these questions, we study the molecular basis of hearing loss as well as hearing function under normal/healthy conditions using various transgenic and knockout mice and cultured mouse inner ear cell lines. A second question being studied in our laboratory is can the progression of hearing loss be slowed? To find these answers, we study the effects of calorie restriction and exercise on hearing in mouse models of hearing loss.

To address this question, we mainly use the genetic model organism C. elegans because of its short generation period and lifespan and powerful genetic tools. Approaches used in the lab including molecular genetics, lifespan and stress assays, calcium and fluorescence imaging, protein biochemistry, and electrophysiology.

My research has concentrated on the regulatory mechanisms of pathological angiogenesis. I made a number of novel and important findings. Such breakthroughs include a) identifying the role of placenta growth factor (PlGF-one member of VEGF family) as a survival factor to remodel and sustain newly-formed vessels by binding to VEGF receptor-1 (VEGFR1) at the later stages of angiogenesis and b) elucidating the mechanism by which pigment epithelium-derived factor (PEDF), a natural potent angiogenic inhibitor, exerts its inhibitory effects on VEGF-induced angiogenesis via the γ-secretase regulated cleavage and intracellular translocation of VEGFR1. These novel studies have been fundamental in providing evidence that VEGFR1 plays an active role in the regulation of angiogenesis. The clinical achievement with angiogenesis inhibitors in cancer treatment is a milestone in the field of angiogenesis research. However, the clinical benefits are transitory and are followed by a restoration of tumor growth and progression. Recently my research interest is expended on establishing research programs centered in the mechanistic basis of this apparent resistance for the therapeutic targeting of tumor angiogenesis. This year I have been awarded a New Investigator Grant from the BankHead Coley Cancer Program. Within the next three or four years I will focus on studying the underlying mechanisms of the strategies adapted by angiogenic-stimulated endothelial cells to perpetuate aberrant angiogenesis within tumor microenvironment, which may will provide some alternative points of therapeutic intervention in anti-angiogenesis strategies.

A focus of our research is to characterize molecular mechanisms of mitogenic signal transduction initiated by the ubiquitous G protein-coupled receptors (GPCRs), with the goal of elucidating novel approaches for intervention in human pathophysiologic processes with special emphasis on genitourinary (e.g. prostate and kidney) cancers. Specifically, we are using molecular, cellular, and animal models to elucidate the role of the GPCRs and their effectors G proteins and βArrestins in the progression of prostate cancer from androgen-dependent to androgen-independent state, and in the metastasis of kidney cancer. A second line of investigation in the laboratory is centered on studying mechanisms involved in vesicle trafficking, with emphasis on the G proteins dynamin that support constriction and fission of vesicles from the plasma membrane into the cytosol. We have discovered that dynamin is post-translationally modified by tyrosine phosphorylation and S-nitrosylation and we are studying the effect of these modifications on its function in active receptor endocytosis and uptake of infectious bacteria and viruses.

Cells are capable of surviving environmental stresses and chemical insult by promoting autophagy that degrades endogenous proteins within lysosomes for recycling of amino acids and sugars. This pathway has also be shown to promote cell survival by removing damaged organelles and intracellular pathogens. Furthermore, dysfunctional autophagy has been implicated in aging, tumor growth, and in the progression of macular degeneration and neurodegenerative diseases. We are collaborating with other UF laboratories to better define the role of autophagy in these diseased states. Autophagy has been shown to have a major role in tumor growth and in the resistance of cancerous tissue to chemotherapy. This degradative pathway recycles nutrients required for tumor growth and provides the cell an avenue for chemotherapy resistance by removing mitochondria that have been damaged by these agents. Autophagy is an essential homeostatic pathway that protects the cells. However, uncontrolled autophagy can result in cell death. We have been collaborating with Dr Law to identify compounds that will suppress or enhance autophagy. We have identified a number of potential compounds that can inhibit key regulatory proteins of autophagy. The effectiveness of these compounds to inhibit or activate autophagy in osteosarcoma, hepatoma, and glioblastoma cell lines is now being assessed by biochemical and morphological means. The next stage will be to evaluate the effects of these compounds on tumor growth in xenograph models. We project these studies will provide new avenues for drug design and therapeutic intervention that will modulate autophagy thereby limiting tumor growth and enhancing chemotherapy susceptibility.

To date we have characterized 8 of the 12 carbonic anhydrases encoded in the mosquito (Anopheles gambiae) genome. Comprehensive gene expression profiling (i.e. DNA micro array analyses) has also been generated which provides the big pictureof gene expression in relation to homeostasis in the various cell types of the larval gut. New emphases that have emerged from the big picture analyses included a focus on gut function in mediating innate immunity, the role of the salivary glands in gut function and homeostatic ion balance as a function of the activity of the hindgut (rectum) of larvae.

Mechanism of colorectal carcinogenesis – Recently, for the first time, we have implicated a novel role of adenomatous polyposis coli (APC) in base excision repair (BER). We hypothesized that, after DNA damage, APC level increases and interacts with DNA polymerase beta and flap-endonuclease 1 and blocks BER. Thus, the compromised BER results in the accumulation of mutations that might be a triggering point for the neoplastic transformation of colorectal epithelial cells.
Mechanism of cigarette smoke carcinogen-induced breast carcinogenesis – In recent studies, we have shown that cigarette smoke condensate-treated normal breast epithelial cells gained a growth advantage over untreated cells in vitro and in vivo. Our long-term goal is to establish the mechanism by which cigarette smoke condensate induces breast carcinogenesis.
Chemotherapeutic intervention of colorectal and breast cancers – Currently, we are actively developing structure-based designing of novel small molecular weight inhibitors to combat these deadly diseases. Several lead compounds have been identified and their usefulness has been proven both in vitro and in vivo studies.

My research interests focus on understanding mechanisms of oncogenic transformation. We have recently studied the role of thymidylate synthase (TS) in tumorigenesis since TS plays a central role in DNA synthesis/repair and high levels of TS have correlated with a poor prognostic outcome in patients with lung, pancreas, colon, and rectal carcinomas. We demonstrated that ectopic expression of catalytically active human TS (hTS) was sufficient to induce a transformed phenotype in mammalian cells both in culture and in transgenic models confirming that it serves as a bona fide cancer therapeutic target. Our current work is focused on defining patterns of cooperation between TS and other cancer genes using a series of defined mouse models. Our goal is to use these transgenic animals to study the in vivo consequences of elevated TS on DNA stability, to test how this relates to tumorigenesis, and to improve the use of TS as a biomarker and therapeutic target.

Stroke is a medical emergency associated with significant emotional and economic burden. In USA stroke kills more than 143,000 people a year and the estimated cost for stroke-related medical costs and disability in 2010 was $73.7. Unfortunately, effective therapy to prevent or minimize stroke is still elusive. One of the proposed and tested (in our lab) pathway mechanism could be Cyclooxygenase (COX)-prostaglandin pathway. COX is the rate-limiting enzyme for the conversion of arachidonic acid to prostaglandin (PG) E2 (PGE2), PGD2, PGF2α, PGI2, and thromboxane A2 (TxA2), collectively known as prostanoids. The prostaglandins play diverse roles in cell activity through their G-protein-coupled receptors (GPCR). The non-steroidal anti-inflammatory drugs (NSAID) have been widely used to inhibit COX-induced inflammation. By inhibiting COX, the NSAIDs also inhibit the PGs, which play a vital role in cellular physiology and pathophysiology. One of the important PGs is PGD2. Interestingly it is the most abundant PG in the brain. Most of the PGD2 activity is regulated by DP1. By using genetic and pharmacologic approach, we are determining the role of PGD2 in stroke. By using DP1 agonist, antagonist, and DP1-/- mice we are determining the role of DP1 in blood flow. Because “brain attack” is an acute process and usually happens without any warnings, scientists are encouraged to find therapeutic intervention(s) that could limit the brain damage after the attack. Therefore, we are also determining if the use of DP1 selective agonist after stroke can extend the therapeutic window such that the treatment could be provided several hours after the onset. Different strategies are being tested to extend the therapeutic window. We are also determining whether the proposed neuroprotection by using DP1 selective agonist is through improved blood flow and vasculature, or does it have a direct neuronal effect mediated by intracellular mechanisms, or a combination of both. We are also correlating the anatomical outcome with behavioral outcomes.

The goal of the team effort directed by Sylvain is to discover new effective mechanisms that limit neuronal dysfunction associated with ischemic and hemorrhagic Stroke, Alzheimer disease, Aging, and various other neurological disorders. The overall objective is to slow down the progression of the disease, and ultimately stop it. To do so, the aim is to limit neuron death resulting from acute and/or chronic neurodegenerative conditions, re-establish normal cerebral blood flow, limit inflammation, stimulate endogenous repair, and restore regular cellular functions. Using a variety of in vitro and in vivo preclinical models, several new hypotheses and potential therapies are being investigated and developed:
- One objective is focused on understanding the actions of prostaglandin (PG) metabolites generated by the degradation of arachidonic acid by cyclooxygenase enzymes. These enzymes are the rate-limiting steps for the production of PGs, which are key elements in the inflammatory response. The resulting consequences are suggested to play an important role in the loss of normal neuronal functions associated with stroke, aging and neurodegenerative disorders.
- We also intend to understand of the protective role of the heme metabolites in the brain using cellular/molecular techniques and various models of ischemic and hemorrhagic stroke, AD, and aging. New knowledge is gained specifically by investigating the action and the role of activity of the heme oxygenase enzyme and its unique bioactive metabolites, namely, carbon monoxide, iron, biliverdin, and bilirubin.
- Our lab also provides molecular evidence for the potential therapeutic applications of complementary and alternative medicines. Using cultures of neurons it was observed that treatment with a standardized extract of Ginkgo biloba could alter the presence of specific genes/proteins important in neuronal function. The lab is exploring the regulation of the transcriptional factor Nrf2, and the increased expression of phase 2 protective enzymes, notably heme oxygenase. Also results have been obtained using resveratrol and other polyphenols, which appear to be active ingredients concentrated in red wines, and which has been proposed to explain some of the beneficial effects associated with the so called “French Paradox.” Similarly, experiments have provided evidence for a unique protective mechanism for the flavanol epicatechin which can be enriched in dark chocolate. These bioactive nutrients could provide resistance against damage induced by free radicals, the toxins which are generated with aging and are the hallmark of many neurodegenerative processes.

Care rendered includes correction of congenital heart defects, heart and lung transplantation, and medical management of cardiac disease. Care is rendered in the Pediatric Cardiac Intensive Care Unit in the north Tower and involves all aspects of critical care medicine including artificial heart support, dialysis, and ventilator support. Operative repairs and cardiac catheterization occur in the operating room and the cardiac catheterization laboratory.
Patient outcomes and Quality and Safety Assurance is increasingly recognized as a cornerstone of evidence based medicine, and is a required activity for many physician leaders.The Congenital Heart Center is conducting numerous Quality and Safety studies to track and improve the peri-operative care of this very fragile patient population. The student who wishes to work within our division will have the opportunity to choose between over thirty Quality/Safety initiatives that range from small to large, and simple to complex. As the interested student participates in these activities they will be exposed to all aspects of pediatric cardiac surgery, anesthesia, pediatric cardiology, and pediatric critical care medicine. Finally, students will participate in the formation of recommendations for changes in the processes used to care for our patients.

Over 60% of surgical patients will suffer from severe acute postoperative pain. While effective non-opioid interventions exist to significantly minimize or even prevent this suffering, such therapies can carry significant costs and risks if not matched to appropriate patients. Our lab applies a variety of machine learning techniques to characterize and forecast severe acute postoperative pain. Active experiments involve content and sentiment analysis of social media, social network analysis, and machine learning of clinical data from UF Health in order to improve our understanding and prediction of severe acute postoperative pain.

We are investigating transcriptional and epigenetic regulation of several human genes in response to nutrient stress; either protein/amino acid deprivation, which activates the Amino Acid Response signaling pathway or ER stress, which activates the Unfolded Protein Response pathway. For example, genomic analysis of the human asparagine synthetase (ASNS) gene has allowed us to identify several genomic cis-acting sequences, the corresponding transcription factors, and the assembly mechanisms of the general transcriptional machinery that are responsible for nutrient-dependent transcriptional control. These data have led us to focus on the molecular control of the genes for the nutrient-responsive transcription factors themselves, to understand the mechanisms for “regulation of the regulators.” Among these transcription factors are ATF4, ATF3, C/EBPb, JUN, FOS, and NF-kB.

Our research focuses on the study of fundamental questions of tissue structure and biochemical processes in living systems accessible to study with nuclear magnetic resonance (NMR) techniques. To provide a detailed understanding of the living system, we are performing detailed investigations of biophysical processes at the cellular and tissue level, along with the development of NMR measurement, processing methods, and specialized hardware. Our current projects are focused on structure and function in the brain: 1) we are using NMR measurements of water translational diffusion in tissue to map fibers in highly structured white matter in the brain and constructing a network map of brain structure, and 2) we are delivering genetic material to specific parts of the brain in order to introducing light-sensitive proteins to the membranes of neurons in the brain to map brain function connectivity. These proteins respond to specific laser light which allows us to directly simulate function in a specific area of the brain then map functional connections to other areas in the brain. The results of these two projects will then be combined to relate structure to function in the brain.

My area of research focuses on improved diagnostics and the prevention of organ dysfunction associated with critical illnesses such as sepsis and shock. The ability of a clinician to avert disease is directly related to whether they can reliably discern which of their many patients are at risk. In the emergency department, prevention is underemphasized. Tools, such as biomarkers and risk stratification calculators, that reliably predict the development of conditions such as severe sepsis, acute respiratory distress syndrome and acute renal failure are underutilized. The consequence is often related to poor outcomes that require prolonged ventilator support, renal replacement therapy, and other resources that impact quality of life, the cost of healthcare, and survival. Current clinical trials enroll emergency department patients with severe illness in an effort to prevent the progression of their disease.

Background: Obesity and cardiometabolic risk disproportionately affects Hispanic American (HA) adolescents relative to their white counterparts. The reasons for such differences appear to be both biological (physiological) and non-biological (environmental). Socioeconomic status (SES) has been consistently used as a proxy for environmental exposure, and an association between lower SES, obesity and cardiometabolic risk has been demonstrated during adolescence and adulthood. In adolescents, recent studies are demonstrating that perceptions of social status are better indicators of obesity risk than traditional SES. However, the nature of perceived social status and its relationship to eating behavior and obesity risk are poorly understood. The objective of this study is to investigate the effect of manipulation of social status condition on eating behavior and obesity risk in 15-18 year old Hispanics.
Hypothesis: Adolescents will consume a greater number of calories, fat, and sugar following the low social status condition when compared to the high social status condition. Obese adolescents will consume a greater number of calories, fat, and sugar following the low social status condition when compared to normal weight adolescents.
Methods: This aim will be accomplished using a randomized crossover design to place adolescents in experimental high and low social status conditions. We will evaluate how much adolescents eat in an ad libitum buffet meal following the manipulation of social status.
Role of medical student: The medical student(s) will be expected to assist in the data collection and data analysis to examine the role of psychosocial outcomes on eating behavior and obesity risk in youth. Expected outcomes include a poster presentation at UF and possibly national meetings and manuscript preparation. In addition, the student(s) will gain joint mentorship and exposure from faculty with the Institute for Child Health Policy, the Department of Health Psychology, the Department of Health Outcomes and Policy, and the Department of Pediatrics.
Funding and relevant publications: Current internal efforts by Health Outcomes and Policy allow for this integrated research. Previous funding for pilot study allotted from University of Colorado and University of Alabama’s Nutrition Obesity Research Centers.

Emergency Department (ED) crowding represents a major threat to the nation’s health care safety net. The reasons for ED crowding are complex and include increased use of EDs for both emergent as well as non-urgent conditions. However, there is little agreement in the published literature regarding the definition of a non-urgent ED visit.
The overall purpose of this project is to define ED visit urgency in order to begin to address the causes and health outcome consequences of ED crowding.

The Segal Lab is focused on understanding the mechanism of the increased cardiovascular risk in unique populations. These populations include patients with chronic kidney disease, patients with lupus nephritis, patients receiving high doses of erythropoietin, women who have complicated pregnancies, and patients who suffer from acute kidney injury. Our hypothesis is that the mechanism of the increased risk in these populations can be determined by analysis of components of the peripheral blood. Our lab has focused on utilizing circulating endothelial cells as a marker of increased endothelial injury and bone marrow derived angiogenic cells as a mechanism of endothelial repair.
With regard to women with complicated pregnancy, dramatic changes occur in the maternal systemic circulation during pregnancy epitomized by massive vasodilation, reduction in systemic vascular resistance and reduction in global arterial compliance. In addition to changes in arterial tone and remodeling, another potential mechanism for the decrease in systemic vascular compliance and increase in global arterial compliance is vasculogenesis and angiogenesis (formation of new or increased branching of existing blood vessels, respectively) or arteriogenesis (increase in compliance by arterial remodeling) via the mobilization of bone marrow derived angiogenic cells. The pregnancy hormone, relaxin, secreted by the corpus luteum during pregnancy, has been shown to replicate the maternal circulatory changes in pregnancy when administered to non-pregnant rats and humans. We were the first to demonstrate that relaxin is a mobilizer of bone marrow derived endothelial cells. Currently we are studying the levels and function of circulating endothelial cells and bone marrow derived endothelial cells in women during spontaneous pregnancies and pregnancies in women who conceived through artificial reproductive technology. We are studying two types of artificial technology: 1) Standard artificial reproductive technology in which the women have supraphysiologic levels of relaxin; and 2) Egg donor artificial reproductive technology in which the women have absolutely no detectable level of relaxin. We are investigating the question as to whether the health of the blood vessels during pregnancy affects future risk of heart disease.

Chronic widespread musculoskeletal pain (CWP) is highly prevalent in the general population (20%) and represents a major cause for dysfunction and loss of income [2; 3] . There are few pharmacological and non-pharmacological therapies available, which generally are of small effect size. Central pain processing abnormalities, including abnormal pain modulation, play an important role for the pathogenesis of this disorder but specific details are lacking . We hypothesize that excessive central pain facilitation is a major factor for patients’ increased pain and pain sensitivity. This hypothesis will be tested by quantitative sensory testing (QST) and functional MRI (fMRI). The student will interact with chronic pain patients and healthy controls and will consent, obtain questionnaires and perform QST (heat and pressure stimuli) on the subjects. He/she will be trained to perform these tasks reliably and how to avoid bias. The student will observe fMRI and will help prepare the subjects for the procedure. The study is funded by NIH and UF funds.

Oxalobacter formigenes is an obligate anaerobic bacterium that is a component of the gut microbiota of humans and other animals. Its sole carbon and energy source is oxalate, the major component of most kidney stones. O. formigenes can decrease urinary oxalate and prevent kidney stones by stimulating the gut epithelium to excrete oxalate from the blood into the intestinal lumen, where the bacteria consume the oxalate. We are using a molecular genetic approach with O. formigenes in a mouse model to elucidate the mechanism by which the bacteria stimulate oxalate excretion and the biology of intestinal colonization. We are combining bacterial genomics and bioinformatics to construct mutations is specific O. formigenes genes, and we examine the mutants for their ability to decrease urinary oxalate in mice fed a high oxalate diet. When genes of interest have been identified, we will determine if they can be expressed in other probiotic bacteria of if their products can be used to treat hyperoxaluria (high urinary oxalate).

Our laboratory studies the interactions between the host mucosal immune system and enteric pathogens, specifically using the enteric noroviruses as a model system. The noroviruses are particularly interesting to us because people fail to develop a lasting protective immune response upon a primary exposure – thus, people can be repeatedly infected by noroviruses. This failure of the host mucosal immune system to maintain protection against a pathogen is also observed with other mucosal pathogens. We believe that the failure can be explained by an aberrant recognition of the pathogen by the mucosal immune system such that it responds as it would to non-pathogenic commensal organisms. This information is critically important to the design of effective vaccines against mucosal pathogens. A second major project in the lab aims to elucidate the mechanisms by which noroviruses cause disease, specifically testing the hypothesis that they encode virulent enterotoxins.

Dr. Lewin’s group uses the tools of gene therapy or drug therapy to prevent blindness caused by inherited retinal degeneration or by age related macular degeneration (AMD). Inherited retina degeneration includes retinitis pigmentosa (RP) which causes progressive loss of vision beginning in the teenage years. Age related macular degeneration develops late in life and leads to loss central vision in >10% of people older than 70. Projects include development of viral vectors to block the expression of mutant forms of rhodopsin; development of viral vectors to prevent oxidative stress and inflammation that contribute to both AMD and RP; and repurposing approved drugs to prevent cell death in both of these diseases. Methods will include molecular cloning, tissue culture, immunochemistry and microscopy. Treatment of experimental animals (mice) will be involved, and student researchers will analyze vision and retinal structure in these animals using advanced imaging and electrophysiology techniques.

The Wallace laboratory is involved in molecular and cellular studies of human diseases that are hereditary in origin or have a genetic predisposition. These studies employ patient samples and mouse models. There are several ongoing projects. One project involves neurofibromatosis type 1 (NF1), a common dominant condition characterized by localized overgrowth/abnormal growth of many tissues (resulting in features such as neurofibromas, skeletal dysplasia, and other tumors such as myeloid leukemia, and GIST in the gut). Studies are underway investigating roles of the NF1 gene protein (neurofibromin) in several tumor types and other NF1 phenotypes. Mutations/expression changes in other genes in these tumors are also being studied. A recent project is genetic association in the depigmentation disorder vitiligo. We have also been involved in gene mapping and mutation analysis in hereditary heart conditions such as primary cardiomyopathy and Pompe disease. Also, we are collaborators in projects identifying genetic polymorphisms that contribute to taste preferences, and baseline pain differences and chronic pain disorders. Thus, this laboratory performs basic and translational research, and works closely with clinicians to obtain patient and family samples.

Our laboratory is interested in understanding transcriptional events of signal transduction pathways critical for normal development and human diseases and one of our current major focuses is a highly conserved cell fate determination pathway mediated by Notch receptors. Aberrant Notch signaling is associated with T cell leukemia as well as a growing number of solid tumors. However, it remains elusive how Notch signaling regulates the growth, survival, and interactions of the tumor cells and its microenvironment during cancer development. Therefore, we aim to elucidate molecular regulation underlying normal and pathological Notch signaling and hope that the knowledge from our research may point to the mechanisms that transform normal cells to cancerous cells, and thus aid in developing novel cancer therapies.
Lei Zhou, Ph.D.
Associate Professor of Molecular Genetics and Microbiology
The overall objective of my research is to understand how the regulatory pathways controlling cellular suicide (apoptosis) are activated in response to cellular stresses and virus infection. Apoptosis is a gene-controlled process that leads to the destruction of obsolete, damaged, or pathogen-infected cells. The destruction of the cell is largely achieved by the activation of a group of proteases called Caspases. Caspases are synthesized as dormant enzymes in essentially all cells, their activation is controlled by several interrelated pathways. While the downstream effector components of these pathways are expressed ubiquitously, the upstream pro-apoptotic regulators are regulated at the transcriptional level. The expression of these upstream pro-apoptotic genes acts as the “trigger” for initiating selective cellular destruction. In mammalian systems, genes encoding BH3-only proteins such as Noxa, Puma, and Bim are the transcriptional targets of P53. In Drosophila, P53 induces apoptosis through transcriptional activation of the RHG (reaper, hid, grim) genes.

Dr. Maciel’s research focuses on improving neuroprognostication techniques and understanding the impact of cortical electrical phenomena (seizures and cortical spreading depression) after acute brain injuries. Dr. Maciel is working to elucidate mechanisms responsible for transient neuronal dysfunction and secondary brain injury which could lead to delayed or incomplete recovery, so that accuracy of neuroprognostication assessments can improve.

My key research focus is to explore how the activation of the innate immune system affects unique sets of pathological hallmarks in different neurodegenerative diseases, including Alzheimer’s disease and Parkinson’s disease. Using recombinant adeno-associated virus mediated gene targeting in mouse models of these human neurodegenerative diseases, I am a) analyzing the effect of immune activation on the neuropathology, and b) designing and testing bioengineered innate immune modulators as therapeutic strategies in these mouse models. Some of the techniques that I frequently use in AAV based modeling and therapeutic studies are: behavioral analysis, high throughput biomarker studies (Nanostring and proteome arrays), biochemical analysis of neuropathological epitopes and MRI. Other secondary techniques, for example, primary neuroglial cultures and flow cytometry are also frequently used. More recently, my research has focused on understanding how specific innate immune mediators affect intrinsic vulnerability of neurons, leading to regionally selective neurodegeneration.

Dr. Dotson’s laboratory is interested in the functional organization of the gustatory system in the periphery, with a particular focus on the receptor basis of taste specificity. Mammals utilize several distinct populations of taste receptor cells to detect chemical cues that contain important information about the quality of foods. Exactly how these various cell populations contribute to the process of translating the physical properties of taste stimuli into neural activity still remains somewhat of a mystery. My laboratory uses sophisticated animal psychophysical testing to evaluate these processes in animals that have genetically or otherwise manipulated nervous systems. These studies may lead to the design of food additives that could benefit individuals suffering from conditions that are linked to excessive intake of foodstuffs (e.g., alcoholism, type 2 diabetes).

The primary emphasis of my research is to identify novel therapeutic targets for neurodegenerative disorders including but not limited to Alzheimer’s Disease, Parkinson’s Disease, and Huntington’s Disease. The identification of these targets is just the first step in a long drug discovery process which includes assay development, development of high throughput screens, and screening of diverse chemical collections including natural product extracts to identify compounds that specifically interact with the target of choice. These so-called ‘hits’ will form the basis of a synthetic chemistry effort, eventually, resulting in the elucidation of an optimized lead candidate with appropriate in-vitro and in-vivo activity. The optimized lead potentially could go on to preclinical/clinical development. Throughout this process the specificity of the interaction is investigated with the potential mechanism of action (MoA) identified. The identification of the MoA in itself may form the foundation of 2nd and 3rd generation drug discovery identification efforts. In parallel, we are also attempting identify biomarkers and be able to assay them routinely from blood or cerebrospinal fluid that could be used not only to determine target engagement but also potentially disease modification. While these translational efforts form the majority of our work we also aim to elucidate potential unifying mechanisms that underly neurodegeneration in general. One such potential mechanism may involve perturbation of mitochondrial dynamics and we are looking at ways to stabilize mitochondria as a potential therapeutic approach.

I am interested in understanding the molecular basis of complex neurodegenerative diseases such as Alzheimer’s disease. To identify new genes and cellular networks with a key role in the neurodegenerative process, we use fruit fly models of several diseases. For this, we express human genes (wild type and mutant) that cause neurodegeneration in the brain of flies and, then, try to identify new genes that lessen the cell loss. In the laboratory we use classic genetics, molecular genetics, RNA/DNA analysis, PCR, Western blot, protein biochemistry, immunofluorescence, cell culture and histological analysis.

Synaptic plasticity is thought to mediate the associative and information storage properties of neurons, and intracellular Ca2+ levels occupy a pivotal position in regulating synaptic plasticity by determining whether synaptic strength increases or decreases in response to neuronal activation. Changes in synaptic strength involve biochemical cascades and ultimately changes in gene regulation. One area of research in my laboratory is directed toward examining age-related changes in this signaling cascade from synaptic plasticity to transcription. The other area involves examining age-relate changes in estrogen. Many effects of estrogen are opposite to those observed during aging; however, the efficacy of the hormone is reduced if therapy is initiated several years after the onset on menopause or after the symptoms of Alzheimer’s disease are manifest.

Current Projects in the Golde Lab and the staff who lead these projects are described below.
- Immunotherapeutic approaches for Alzheimer’s disease and other amyloid disease (Yona Levites, PhD, Pedro Cruz PhD). Aggregation and accumulation of the amyloid β protein in the brain is thought to trigger a complex degenerative cascade that results in Alzheimer’s disease. These studies build on ~10 years of research in the labaoroty and are designed to develop novel active and passive immunotherapies that safely and effectively target AB amyloid in AD. Notably these therapies may have benefit in other amyloid diseases. Funded by the NIH/NIA http://projectreporter.nih.gov/project_info_description.cfm?aid=7796588&icde=5525743
- Gamma-Secretase Modulators and the role of short amyloid pep tides in Alzheimer’s disease. (Thomas Ladd, Brenda Moore PhD). A longer species of Aβ, Aβ42, is thought to be the key pathogenic molecular in AD. It is critical for deposition of Aβ. Thus, lowering levels of Aβ42 could have a major impact on the development of AD. In collaboration with Dr. Edward Koo’s laboratory (UCSD), we previously demonstrated that select drug and drug-like compounds could modulate A42 production and that this effect was attributable to direct alteration of -secretase activity. Drug with this type of effect oon Aβ are now referred to as a -secretase modulators (GSMs). These studies provided the rationale for clinical testing of GMSs by the commercial sector. Our current collaborative studies are designed to examine more closely how GSMs work, and whether short Aβ peptides are protective. Funded by the NIH/NIA. http://projectreporter.nih.gov/project_info_description.cfm?aid=8111733&icde=5525743
- Therapeutic Targeting of Intramembrane Cleaving Protease. (collaborations with Dr. Wolfe Harvard, Drs. Osborne (U. MASS), Miele (Loyola/U. Miss), M. Bouton (U. FL) and Greenbaum ( U. Penn)). Presenilin is the catalytic component of a multisubunit protease called -secretase that cleaves membrane proteins within their transmembrane domains. -Secretase cleaves a number of proteins and mediates signal transduction by many of these. In 2003, in collaboration with Dr. Chris Ponting, we identified a family of intramembrane proteases (signal peptide peptidase) that were related to -secretase. We are evaluating targeting these proteases in cancer, immunologic disease, and malaria. Funded by the NIH/NIA. http://projectreporter.nih.gov/project_info_description.cfm?aid=8098929&icde=5525743
- Proteinopathy induced Senescence Reponses in Neurodegenerative Disease (Wei Kou PHD, Paramita Chakrabarty PhD). We are exploring an alternative way in which protein accumulation in the brian might lead to brian organ failure. We hypothesize that protein misfolding and aggregation triggers a self-reinforcing cycle of chronic stress (sub-lethal toxicity), pro-inflammatory signals and a senescence response (Golde and Miller, Alz Res Ther 2009). We will examine whether under stress, neurons can undergo changes that phenocopy aspects of replicative senescence and whether these senescent changes are accelerated in AD and other CNS proteinopathies. To avoid confusion over semantics, we will refer to a putative stress response in non-dividing, terminally differentiated cells that mimics phenotypes seen in replicatively senescent cells as a senescence response. Funded by the Ellison Senior Scholar Award
- Somatic Brian transgenesis and AAV based models of Neurodegeneration (Yona Levites, PhD, Carolina Ceballos-Diaz, and Paramita Chakrabarty PhD). We have developed a method using viral vectors to transduce large portions of the neonatal brain. We refer to this technique as somatic Brain transgenesis. Using this technique we can much more rapidly model various aspects of neurodegenerative disease for a fraction of the costs associated with traditional transgenics. We have established over a dozen collaborations based on this technique.
- Inflammatory and Immune Mediators in Neurodegeneration. (Paramita Chakrabarty, Carolina-Ceballos Diaz, Pedro Cruz PhD, Wie Kou PhD). Recent work from our lab has challenged a long-standing hypothesis that inflammatory processes in AD accelerate Aβ deposition. Unpublished studies also reveal a potential novel role of interferon in nigrostriatal degeneration. Using the somatic brain transgenic technology described above we plan to more broadly explore immune modulators as mediators of neurodegenerative pathways.

The overall goal of my research program is to understand how the dopamine transporter (DAT) regulates biological responses, and how thisregulation is modulated by structural differences in ligands acting at DAT and by DAT-interacting proteins. As an example, by discovering the mechanisms by which the DAT substrate methamphetamine induces its unique addictive qualities, we will not only reveal novel therapeutic targets for intervention/prophylaxis of disorders associated with dysregulation of the dopaminergic system, but almost certainly ascertain new molecular mechanisms for transporter-effected signal transduction. Finally, I also intend that my research laboratory will provide an outstanding venue for the training of undergraduate and graduate trainees.

Olfactory disorders affect a significant portion of the population. Disorders in the sense of smell can be caused by aging, traumatic injuries, infections and genetic mutations. Defects in ion channel function underlie an emerging class of human genetic diseases, termed channelopathies. In addition to other sensory defects, channelopathies can cause the loss of the sense of smell. Our research aims to identify mechanisms by which specific ion channels regulate olfactory signaling, how these are disrupted in disease states and the ability to correct channel defects. The ultimate goal of this work is to demonstrate functional recovery of olfactory function in channelopathy models for the further development of treatments for human patients.
Additionally, my lab studies the role of primary cilia on the neurons present in the olfactory bulb. Primary cilia are a type of cellular “antenna” that function to sense cues in the extracellular environment. However the precise roles for these organelles on neurons in the brain remain unknown. Many of these cilia possess G-protein coupled receptors for neuromodulatory signals. The aim of this project is to elucidate the role for cilia in modulating neuronal function in the olfactory bulb.

We study the regulation of a subset of genes regulated by pro-inflammatory cytokines that play a cytotoxic or cytoprotective role in the inflammatory response in the brain, lung and kidney.
Lucia Notterpek, Ph.D.
Professor and Chair
Dr. Notterpek investigates how the loss of glial insulation around axons, called myelin, contributes to the pathogenesis of neural disorders. Diseases that are specifically linked with defects in myelin include peripheral neuropathies, such as Charcot-Marie-Tooth diseases and multiple sclerosis. Recent studies also suggest an involvement of myelin damage in underlying the painful symptoms of trigeminal neuralgia. Current research is focused on understanding the subcellular changes within neural cells that underlie the progressive nature of these disorders and to identify approaches to restore myelin and neural function. The laboratory is equipped with models and reagents, including small molecule therapeutics and genetic modifications to attain these goals. Other areas of active investigation include the role of gene regulatory mechanisms in peripheral nerve development, and the effects of aging on neuromuscular function.

Excessive scarring of corneal wounds causes impaired vision. Therapies currently used to reduce corneal scarring use non-specific drugs, including anti-inflammatory steroids or anti-proliferative cancer drugs like 5-fluorouridine (5FU) or mitomycin-C that can cause severe, long-term side effects. We are developing antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs) that specifically target mRNAs for the two growth factors, transforming growth factor beta (TGFb) and connective tissue growth factor (CTGF), that are known to regulate scarring in the cornea and in other tissues in the body. Initial studies with these new drugs show significant reduction of the target mRNAs in cultures of corneal fibroblasts and reduced corneal scarring in rabbit models following excimer ablation of corneas. In this project, the student will participate in experiments using gene-targeted therapy to reduce corneal scarring. The student will assist in surgery creating corneal wounds, measure expression of TGFb and CTGF mRNA and proteins, and measure corneal scarring (haze) in photographs of rabbit corneas. The student should have basic understanding of biochemistry and molecular biology techniques and be willing to work with laboratory animals.

1) Developing an AAV-based therapy for the treatment of GUCY2D-LCA1. Dr. Boye manages the pre-clinical, proof-of-concept and safety studies aimed to bring this treatment from bench to bedside within the next couple of years.
2) Optimizing AAV vectors to successfully treat diseases which involve mutations in large genes (something recently considered outside the scope of standard AAV gene therapy).
3) Developing novel viral vectors capable of delivering therapeutic genes to the outer retina (photoreceptors) following a surgically less invasive, intravitreal injection.

Our research is mainly focused on retinal renin angiotensin system. The renin-angiotensin system (RAS) plays a vital role in the cardiovascular system. Angiotensin II (Ang II), a key peptide hormone of RAS, has been known to regulate a variety of hemodynamic physiological responses, including fluid homeostasis, renal function, and contraction of vascular smooth muscle. In addition, elevated level of Ang II is capable of inducing a multitude of non-hemodynamic effects, such as the induction of reactive oxygen species (ROS) and expression proinflammatory cytokines, leading increased oxidative stress and inflammation. Classically, RAS is considered a circulating hormone system consisting of a linear cascade of Ang II generation. However local RAS exists in almost every organ including the CNS and eye, and plays vital role in neuro-vascular function and modulating local immune responses. Furthermore, the discovery of angiotensin-converting enzyme 2 (ACE2) has resulted in the establishment of a novel axis of RAS involving ACE2/Ang-(1-7)/Mas. ACE2 is able to cleave Ang II to form Angiotensin-(1-7) (Ang-(1-7)). Ang-(1-7) binds to a G-protein coupled receptor, Mas, and activates signaling pathways that counteract the effects of Ang II. Thus the ACE2/Ang-(1-7)/Mas axis has emerged as a critical regulator of Ang II/AT1R signaling. Accumulating evidence has also demonstrated that enhanced expression of Ang-(1-7) and ACE2 reduces inflammation, oxidative damage, inhibits pathologic angiogenesis, and confers protection against a variety of pathological conditions including metabolic syndrome, diabetes and its complications; neuro-vascular dysfunctions and neurological diseases. Our current research projects are primarily focused on this protective axis (ACE2, Ang-(1-7) and Mas receptor).
Two main aspects of our current research projects, funded by NIH, American Diabetes Association and BrightFocus foundation, are: (1) Translational studies- to enhance this protective axis using various approaches, including local ocular gene delivery via recombinant adeno-associated viral vectors, pharmacological and oral delivery of proteins expressed and bioencapsulated in plant cells, to treat (both prevention and possibly reversal) a number of retinal diseases including diabetic retinopathy, age-related macular degeneration, and inherited photoreceptor degeneration in animal models; (2) Basic research studies- although the protective effects of Ang-(1-7)/Mas signaling are well-established in many organs under many different pathological conditions including the CNS, the signaling mechanisms and downstream target genes are largely unknown. Our long term goal is to further elucidate these signaling mechanisms and downstream genes involved in the protective actions of Ang-(1-7) in the retina and their interactions with other pathways implicated in the pathogenesis of retinal diseases in order to develop more effective and targeted therapeutics.

Eyes are exquisitely sensitive detectors, capable of registering a single photon of light. In my lab, we focus on how eyes achieve this amazing quantum detection ability. Our primary interests cover the biochemistry and cellular biology of the early events in this process– how the eye captures photons, and how this information is reliably translated into a signal that can be utilized by the brain to form an image. Since defects in this process often lead to visual complications, such as retinal degeneration and stationary night blindness, we anticipate that our studies will lead to therapies for these associated diseases. In my lab, we utilize the tools of molecular biology, protein chemistry, structural biology, and cell biology to delve into these questions.

With the increasing association of Human Papillomavirus (HPV) and the oral cancers, my studies involve screening healthy adults and head and neck cancer patients for HPV infection. HPV-positive tumors have been more responsive to cancer treatment options than HPV-negative tumors, therefore we are studying the molecular biology of HPV-induced tumors. For the treatment of head and neck cancer patients, my research involves screening compounds (small molecular inhibitors, novel agents, or single-chain antibodies) for anti-tumor activity and analyzing the compounds for synergistic activity with radiation and chemotherapeutic agents. These investigations include mechanistic studies to understand the anti-tumor activity of these novel agents.

Dr. Mathews’ studies have forged a new path in the understanding of autoimmune diabetes. While the majority of the field focuses on identifying defects in cells of the immune system, the guiding hypothesis of Dr. Mathews’ research is that insulin secreting pancreatic beta cells are active contributors to the autoimmune process in T1D. The initial publications from Dr. Mathews demonstrating that pancreatic islets had down regulated self-defenses, and that this reduction was important in the initiation of diabetes. The extension of this work strongly supported the hypothesis that beta cells play an active role in the pathogenesis of diabetes. The findings demonstrated that islets varied in their resistance to autoimmune destruction and further that islets from different donors ranged from highly susceptible to extremely resistant to damage. These novel findings proved to be influential because, prior to this paper, there was no evidence suggesting that beta cells could resist autoimmune destruction. Dr. Mathews’ investigations have provided the proof of concept for many subsequent therapy studies y both his and other groups. These findings also led Dr. Mathews a postulate that there are genetic factors expressed at the level of the pancreatic islet that provide resistance to autoimmune diabetes. His successive publications have supported this hypothesis and have identified a gene (mt-Nd2) that is responsible for protection as well as to the identification of the signaling pathways that can be blocked inhibiting beta cell death without modifying beta cell insulin secretory activity. The discovery of genes that pancreatic islets employ to ward off autoimmune effector mechanisms have important ramifications for transplantation, stem cell engineering, and future genetic and pharmacological diabetes preventative therapies.

Dr. Morel’s research focuses on the genetic analysis of lupus susceptibility using a mouse model and validates the findings obtained in the mouse with immune cells obtained from lupus patients and healthy controls. The long-term goal of this research is to identify the genes responsible for lupus susceptibility and to characterize their contribution to autoimmune immunopathology. This is a multifaceted project combining immunological and genetic approaches that has established her expertise in lupus genetics and more generally in the genetics of autoimmune diseases and in mouse models of autoimmune pathogenesis. The complexity of lupus genetics stems from the fact that it is a polygenic disease and that no single gene is required for disease development. Dr. Morel has made a significant contribution to the field of complex trait genetics, and lupus genetics in particular, by showing that lupus susceptibility was inherited as a threshold liability of a combination of four susceptibility alleles. Dr. Morel has defined a conceptual approach, the congenic dissection, which is now widely used to analyze complex traits in animal models. In the process, they have updated the production of congenic strains to molecular screens and develop the “speed-congenic” method, which is now considered to standard approach for the production of congenic strains.
Dr. Morel has made considerable progress toward the identification of lupus susceptibility genes and in their functional characterization. She has shown that lupus pathogenesis was reconstituted by the combination of three chromosomal regions from the lupus-prone strain in a triple congenic strain. This was a landmark study in the field that has not been achieved in any other models. This BcN/LmoJ triple congenic strain is now the basic model to study lupus immunogenetics and mechanisms of tolerance in Dr. Morel’s lab. This BcN/LmoJ strain has now been licensed and it is distributed by the Jackson Laboratories to numerous investigators and companies. Dr. Morel’s research now focuses of characterizing the contribution to autoimmune pathogenesis of several genes that she has positionally cloned as lupus susceptibility genes in the NZM2410 mouse. These genes, which include homeobox protein (Pbx1), orphan nuclear receptor (Esrrg), cell cycle regulator (Cdkn2c), SAP family adaptor (Sh2d1b1) and growth factor receptor (Csf3r), are very diverse in function and cellular target of expression. Finally, Dr. Morel is conducting research on the genetic regulation of cellular metabolism in immune cells and how it can be used to treat lupus with metabolic inhibitors.

Induced pluripotent stem cells (iPSCs) are a newest type of stem cells artificially generated by transiently expressing a set of exogenous transcription factors in somatic cells such as skin fibroblasts. The iPSCs can differentiate into all the cell types in our body such as neurons and cardiomyocytes as embryonic stem cells (ESCs) do. Since Yamanaka (2006) originally reported the method for iPSC induction, the field has been rapidly expanding with great expectation. Essentially, the clinical implications of iPSCs are in two fold; first, as a cellular resource for transplantation therapy, and second, as a system to model human diseases. In my laboratory, in collaboration with many clinical investigators, we focus on utilizing patient-derived iPSCs for understanding disease mechanisms and for drug discovery. We welcome highly motivated and innovative undergraduate students to join our effort.

On-going research in my laboratory focuses on major areas of adult stem cell plasticity for a cure/management of type 1 diabetes mellitus (T1DM). Over the past several years, we have made great progress by discovering ways to transdifferentiate adult stem cells (bone marrow, liver stem cells, and splenocytes) into functional insulin-producing pancreatic islet-like cells extrinsically by manipulating culture microenvironments and intrinsically by over-expressing those transcription factor(s) playing critical roles in pancreatic beta-cell development. In addition, we are pursuing two additional research projects: (1) Explore molecular mechanism of ATRA-induced cell differentiation in acute promyelocytic leukemia; and (2) Generate tumor-antigen-specific cytotoxic T-cells for the treatment of multiple myeloma.

The major interest of the laboratory is to determine the primary mechanism by which respiratory muscles display decreased activation or force-generating capacity in models of neuromuscular disease. A specific example is Pompe disease which affects the central nervous system, neuromuscular junction, and skeletal muscle; ultimately resulting in respiratory and ambulatory dysfunction. Our studies have focused on identification of each of these aspects to determine their contribution to loss of proper maintenance and function in these systems. To accomplish this, our approach incorporates an array of molecular, biochemical, and physiological measurements. In addition, we have found that recombinant adeno-associated viral (rAAV) vectors can be tailored to provide adequate gene expression in skeletal muscle and the CNS in a mouse model of Pompe disease. Specifically, rAAV therapy has reversed the disease associated phenotype and restored motoneuron and respiratory muscle function. Further optimization of rAAV vectors has led to improved transduction efficiency and may allow for a reduction in viral particles required to provide a therapeutic benefit. This may be critical in reducing potential immunoreactivity to the rAAV capsid and/or transgene and provide improved outcomes in affected patients. http://falk.research.pediatrics.med.ufl.edu/

Our primary focus is to develop adeno-associated virus (AAV) mediated gene therapy and mitochondrial transplantation therapy to treat disorders that affect mitochondrial function. The lab has deep expertise in the use of various serotypes of AAV combined with tissue specific promoters to achieve robust transgene expression for the treatment of genetic disorders. We are particularly interested in developing treatments for the following two genetic diseases:
Barth Syndrome – an X-linked mitochondrial disease that causes dilated cardiomyopathy, neutropenia, muscle weakness, growth delay and exercise intolerance. The underlying problem is a mutation in the tafazzin gene which causes a decrease in cardiolipin synthesis.
Cockayne Syndrome – a multi-system autosomal recessive neurodegenerative disorder characterized by growth failure, nervous system impairment, photosensitivity, eye abnormalities, liver dysfunction, and a variety of other symptoms caused by premature aging. A defect in transcription-coupled DNA repair and its consequences in the repair of mtDNA contribute to the pathophysiology of this disease.
Additionally, recent collaborative work demonstrated that ischemia reperfusion injury can be prevented by injecting mitochondria isolated from healthy unaffected tissue into a heart model of regional cardiac ischemia. The hearts that received mitochondria displayed a significant decrease in apoptosis and infarct size as well as an increase in regional function as compared to controls. Based upon these exciting results we are now developing the same concept of mitochondrial transplantation therapy to ameliorate mitochondrial impairment in neuronal cells caused by cerebral hypoxia in newborns.

My current research focuses on the patho-physiology of the liver, particularly the mechanisms involved in fibrotic response during hepatic progenitor cell activation and liver cancer development. Alcohol and high fat diet (HFD) influence the function of a wide range of cells and tissues. They can interact with cellular components or indirectly affect systemic oxidative and inflammatory states via intermediate metabolites. Persistent damage causes chronic injury leading to hepatic progenitor cell (HPC) activation and life-threatening fibrotic diseases such as alcoholic cirrhosis and nonalcoholic steatohepatitis (NASH). Dynamic extracellular matrix (ECM) remodeling is involved in these fibrotic diseases via transcriptional regulators, growth factors and proteases. Connective tissue growth factor (CTGF) is an extracellular signaling modulator in the CCN (Cyr61/CTGF/Nov) family important for hepatic progenitor cell activation and liver repair. Overexpression of CTGF is a hallmark in fibrotic disorders. Two regulators of CTGF, ADAMTS7 (a disintegrin and metalloproteinase with thrombospondin type I repeat 7) and the transcriptional coactivator YAP (Yes-associated protein), have been identified. We are currently using our established alcohol and NASH models to investigate the roles of ADAMTS7 and YAP in CTGF mediated HPC activation, alcohol fibrosis and NASH diseases. Some of our recent publications are below.

Through multidisciplinary work in medicine, public health/ health services research and education, we, as investigators with the Division of General Pediatrics, employ techniques of observational research to understand outcomes in health and well-being. We are currently involved in several projects in education and medicine, although we specifically are seeking help in investigating online profiles and their relationships to health. We argue that the degree of overlap between high-risk behaviors depicted in online social networking profiles (eg: Facebook, MySpace) and real-life, high-risk behaviors (alcohol, drug, tobacco consumption, sexual practices, etc) is unknown. Our research aims to explore two related objectives: first, it aims to establish a rubric, or tool, to reliably quantify the content of online social networking profiles. Second, it aims to test whether high-risk behaviors depicted in individual online social networking profiles are associated with participation in real-life, high-risk behaviors, and to establish how personal characteristics such as age, gender and race/ethnicity affect this relationship.

Increasing evidence indicates that alteration of the normal prenatal environment affects development and can influence an individual’s lifetime risk of developing obesity and cardiovascular disease. Thus, understanding how in utero exposure to chemical agents lead to increased susceptibility to adult diseases is the goal of my research. Previously, we have demonstrated that adenosine A1 receptor (A1AR) signaling protects the embryo from hypoxic conditions in utero. In addition, we have revealed that in utero caffeine exposure has long-term effects on cardiac function and morphology in adult offspring, and that these effects are mediated by A1AR action. Recently, we have demonstrated that in utero caffeine treatment leads to changes in DNA methylation patterns in adult hearts. And we are currently pursuing research to determine if these changes in DNA methylation mediate the changes we see in adult hearts. In addition, we have begun to examine whether caffeine exposure in utero has transgenerational effects on heart function.

We have two ongoing projects:
- Investigating the role of The CUB Domain-Containing Protein 1 (CDCP1) in breast cancer metastasis- We have discovered that the transmembrane protein CDCP1 activates several biochemical pathways that allow cancer cells to survive in the detached state during the process of metastasis. Current efforts involve understanding how CDCP1 activates these different downstream pathways through the tyrosine phosphorylation of different residues in the CDCP1 cytoplasmic domain, identifying CDCP1-associated proteins using affinity chromatography/mass spectrometry approaches (i.e. proteomics), and testing new therapeutic strategies for neutralizing CDCP1 function to prevent breast cancer metastasis.
- Characterization and optimization of a novel class of anticancer agents that downregulate the EGFR, HER2, and HER3 receptor tyrosine kinases- We have identified a new class of compounds that inactivate the oncogenic Epidermal Growth Factor Receptor (EGFR) family of proteins EGFR, HER2, and HER3 by disrupting the disulfide bonds present in the conserved cysteine-rich extracellular domains of these proteins. These agents, which we term Disulfide bond Disrupting Agents (DDAs) are promising anticancer agents in that they exhibit anticancer activity in vivo and exhibit no detectable toxicity. This is a collaborative project between the Castellano Laboratory in the Chemistry Department and the Law Laboratory in the Pharmacology Department. Approaches used in this project include: Chemical synthesis and characterization, testing compounds in cell culture studies, and using protein chemistry/proteomics approaches to validate EGFR, HER2, and HER3 as DDA targets and to identify additional targets of these anticancer agents.

A significant number of adult-onset neurological diseases, including Alzheimer’s, Parkinson’s and Huntington’s disease are characterized by the aberrant and toxic accumulation of proteins in affected neurons. Our group relies on the use of model systems to test novel gene-based therapies that prevent, halt or reverse these “proteinopathies”. In particular, we develop Adeno-Associated virus-based gene therapies to suppress the expression of these proteins in affected neurons. Recently, using models of spinocerebellar ataxias, we have demonstrated that suppressing the expression of toxic proteins, even after disease onset, can lead to significant recovery of neuronal function and halt the progression of pathology. A new exciting area of gene therapy research in our group focuses on the development of “gene-editing” tools that can be used to modify inherited mutations in adult neurons.

A major goal of my research program is to elucidate mechanisms underlying obesity and co-morbid conditions such as hypertension and diabetes. A particular emphasis is placed on the interactions among neural circuits that regulate energy balance with those that control blood pressure, and also on the impact that the renin-angiotensin system has on these circuits. Some specific research topics currently being explored include: (1) examining the role of angiotensin-II and related peptides in the neuroendocrine regulation of energy balance; (2) optogenetic targetting of angiotensin-sensitive neurons of the nodose ganglion to combat obesity and hypertension; and (3) evaluating mechanisms by which angiotensin-sensitive neurons of the median preoptic nucleus coordinate physiological and pathophysiological responses to hypertensive stimuli. In order to explore these and other research topics, we use a mutli-level approach that spans the use of several molecular, genetic, physiological and behavioral techniques. Some examples of the approaches used are: telemetry and indirect calorimetery, which are used to assess cardiovascular parameters and energy expenditure respectively; optogenetics, fiber photometry, neuronal tract tracing, mRNA in situ hybridization, and immunohistochemistry, which are used to characterize the structure and function of specific sets of neurons involved in these processes; and genetic recombination and virally-mediated gene transfer techniques, which allow for the manipulation of gene expression in specific cellular phenotypes.

Circadian rhythms are well known daily patterns in sleep/wake cycles and core body temperature. Recent discoveries have uncovered that the molecular clock mechanism underlying circadian rhythms exists in all cells in the body. My lab is currently pursuing three main areas of research related to circadian rhythms and skeletal muscle. Using targeted genetic mouse models, we have found that the clock mechanism in skeletal muscle modulates fat/carbohydrate metabolism, muscle structure/function in the presence of normal circadian function in the brain. We are pursuing these observations to define the transcriptional and translational networks regulated by the molecular clock in skeletal muscle that regulate both metabolism and function. The second area of study is based on the recent work that has shown that time of activity/exercise can function as a cue to “set” the clocks in skeletal muscle independent the brain. We are using cell culture models of muscle contraction combined with unique exercise paradigms to define the mechanisms by which activity can regulate the molecular clock. Lastly, we are working to develop analytic techniques to use biometric data obtained from wearable devices to define “circadian health” in human populations.

Withdrawal from drug of abuse increases the brain reward threshold (i.e. depressive like state) and we try to reverse this by using CRF antagonists and other novel pharmacological treatments for mood disorders. The student will become experience with the following techniques: Surgical techniques: Implantation of electrodes and cannulae in the brain; implantation and removal and subcutaneous minipumps that contain drugs of abuse. Injection procedures: Subcutaneous, intraperitoneal and intracranial administration of drugs. In addition the student will gain extensive knowledge about animal care, how to conduct scientific experiment and drug dependence research. This projected will be conducted in close collaboration with Dr. Mark Gold.

My lab works with animal models of autism and related neurodevelopmental disorders. Specifically we are focused on the abnormal repetitive behavior (e.g., stereotyped behavior, compulsions, rituals, insistence on sameness) characteristic of children and adults with these developmental disorders. We are investigating the neurobiology underlying the development and expression of abnormal repetitive behavior in several animal models. Our research with deer mice involves examining the brain changes associated with the development of abnormal repetitive behavior and its prevention by early experience. These studies include examination of developmental trajectories and the temporal organization of repetitive behavior and associated changes in key pathways in cortical basal ganglia circuitry. These biochemical and pharmacological studies have not only identified neurobiological mechanisms but have identified potential therapeutic targets for the treatment of these behaviors. Other work with an inbred mouse strain is focused on identifying genetic loci that mediate the development and expression of repetitive behavior.

We study basal ganglia circuitry dysfunction as it relates to maladaptive behaviors that are phenotypic for psychiatric (e.g. OCD) and neurodevelopmental disorders (e.g. autism, intellectual disabilities), using mouse models. Our mice exhibit high rates of repetitive behaviors as a consequence of genetic manipulations or environmental impoverishment. Our experiments utilize molecular techniques as well as psychopharmacology and drug development to investigate neuropathology and targeted drug treatments.

My research is devoted to the advancement of magnetic resonance imaging (MRI) technology for applications in health and disease in humans, with a focus on brain functional MRI (fMRI). Going beyond the traditional strength of MRI for providing images of the structure/anatomy of the body in health and disease, fMRI allows for imaging the human brain at activity (e.g., thinking, seeing, hearing, etc.) by detecting cerebral hemodynamic responses (i.e., microscopic blood flow or perfusion, and oxygen consumption by brain tissues) accompanying brain activity. fMRI can also be applied to studying/monitoring effects of a treatment, therapy or intervention. We offer excellent opportunities for students to participate in our exciting research, with a particular emphasis on translational MRI research in humans.

Our team recently solved the technical challenges of extracting and characterizing the structure of lung vessels in 3D from medical images, and we have two patents pending for these new tools. The long-term purpose of our current work is to apply and optimize these tools for use in 3 classes of patients: (1) children born before their lung vessels have fully deformed; (2) teenagers with pulmonary vessel insufficiency (often as a result of being born prematurely); and (3) adults with chronic pulmonary hypertension (PAH). Our clinical objectives are to (1) characterize the development of the pulmonary vessels over time in prematurely-born infants; (2) determine the time-course of progressive vessel disease in these children as they age into young-adulthood; and (3) to study vascular remodeling with chronic PAH. In parallel with the clinical work, our technological objectives are to (4) characterize and validate the accuracy and sensitivity of the method, (5) compare our results against competing approaches; and (6) optimize and streamline the analysis algorithms to position ourselves strongly for additional funding.

Work in Dr. Berceli’s lab is focused on the process of the vascular response to injury, with a specific interest in understanding the role of biomechanical forces in mediating these events. Although these concepts are also seen in vascular problems such as atherosclerosis and arteriogenesis, our current basic science and translational research projects examine the dynamic interplay among the various forces that lead to luminal narrowing following vein bypass grafting. Integrating mathematics, engineering, and vascular biology, research opportunities in our laboratory offer a range of experiences, from bench top testing to in vivo experimentation to the development of in silico computational models.

Our research focuses in two main areas – translational biology and outcomes research. We have had students contribute significantly in both of these areas during past experiences.
Translational Research: We study the functional genomics and proteomics linking systemic inflammation to success or failure of vascular surgical procedures, currently lower extremity stenting and/or bypass surgery. This project involves genetic analyses using state of the art microarray technology, high throughput proteomics, and sophisticated bioinformatics to investigate whether or not a person’s innate immunity pre-operatively or their inflammatory reaction to the procedure itself can predict the success or failure of that intervention and therefore be used to improve treatment strategies.
Clinical/Outcomes Research: Here we use our local UF experience combined with large administrative databases to understand and compare local/regional and national trends in vascular surgery. Projects focusing on lower extremity revascularization, abdominal aortic and thoracic aortic aneurysm repair, and venous disease are underway to identify the impact of new technology and to better define expected outcomes in these areas. We are also involved in a number and variety of clinical trials relevant to vascular surgery.

Our studies are focused on mechanisms of tumor-induced immune suppression and immune tolerance. We are trying to dissect the role of CD11b myeloid cells in the regulation of anti-tumor immune response in both cancer patients and tumor-bearing mice. Currently, several projects are underway, including characterization of myeloid suppressor cells population in peripheral blood of cancer patients with bladder and renal cell carcinoma. Another interest concerns regulatory mechanisms of local immune response in tumor microenvironment. We investigate several genes and transcription factors which are affected in tumor-infiltrated myeloid cells and precursors of antigen-presenting cells. The ultimate goal of our research is correction of tumor-induced dysfunction, activation of immune system and induction of therapeutic immune response.
