Graduate Student, Cone laboratory, Molecular Physiology & Biophysics
My research project is focused on advancing our understanding of the molecular and kinetic mechanisms of energy maintenance by elucidating if and when MC4R induced Kir7.1 signaling is required for regulation of food intake and energy expenditure. We believe MC4R functions as a rheostat of energy maintenance by utilizing both tissue specific Gαs and Kir7.1 signaling modalities as well as unique kinetic aspects of these modalities. I am using an in vivo modeling system to test this hypothesis.

Research in the Ayala lab focuses on gut-brain interactions that regulate energy balance. Specifically, we are interested in identifying regions in the central nervous system and molecular mechanisms within those regions that mediate the effects of the gut hormone Glucagon-like peptide-1 (Glp1) and related Glp1 receptor (Glp1r) agonists on feeding behavior. Our lab combines transgenic mouse models, targeted pharmacological interventions and state-of-the-art metabolic phenotyping capabilities to address research questions. We aim to extend the technical expertise in the lab to leverage the existing imaging, circuit mapping, electrophysiology and behavioral phenotyping capabilities at Vanderbilt. Other projects in the lab focus on leveraging biochemical and pharmacological properties of the Glp1r towards the design of more effective therapeutics for obesity and diabetes

AMPA receptors (AMPARs) are ligand-gated cation channels whose appropriate activity and regulation are integral to most central nervous system function. They mediate the majority of excitatory neurotransmission and their dysregulation has been implicated in many cognitive disorders. My research focuses on the molecular details of auxiliary subunit interactions with the AMPAR. Using biochemical and structural biology techniques, we hope to illuminate the molecular basis of interaction between these two proteins and how that relates to the auxiliary subunit’s modulation of AMPAR in vivo.

Elevated fasting blood glucose (FBG) levels have been associated with an increased risk of type 2 diabetes (T2D) development and cardiovascular-associated mortality (CAM). Genome-wide association studies (GWAS) have identified SNPs in G6PC2 associated with FBG. G6PC2 is an isoform of the glucose-6-phosphatase catalytic subunit expressed in pancreatic islet beta cells. Deletion of G6pc2 in mice results in reduced FBG, consistent with the human GWAS data, and islets from these mice have enhanced glucose-stimulated insulin secretion (GSIS) at sub-maximal glucose concentrations. I am using mouse models to explore the function of G6pc2 in islet beta cells and its potential as a therapeutic target for the prevention of T2D and CAM.

Titin, the largest known protein, is indispensable for the structural integrity and function of the cardiac sarcomere. Yet, how such a massive ~3 mDa structural protein is maintained within the highly ordered sarcomere complex, while under continuously alternating tension, is unknown. My thesis focuses on elucidating the mechanisms mediating sarcomere homeostasis in human induced pluripotent stem cell-derived cardiomyocytes. Using CRISPR/Cas9 gene editing, I generated a novel model in which I can directly visualize sarcomeric titin in order to address fundamental questions regarding titin turnover, which is critical for sarcomere homeostasis.
Graduate Student, Maureen Gannon laboratory, Molecular Physiology & Biophysics
Prostaglandins are important modulators of an array of physiologic functions including insulin secretion and systemic inflammation. In the Gannon lab, I focus on the specific roles of the prostaglandin E2 receptors EP3 and EP4 and how they regulate processes involved in β-cell mass expansion. I am using pharmacological tools to examine the effects of EP3 and EP4 signaling in β-cell proliferation and β-cell survival in isolated mouse and human islets. I am also studying the effects of an EP3 antagonist and an EP4 agonist on β-cell proliferation and β-cell survival in the db/db mouse model of type 2 diabetes.

Dr. Corbin, together with Dr. Sharon Francis, devoted his research career to determining the biochemical mechanisms whereby cyclic nucleotides mediate the effects of hormones, neurotransmitters, and other agents on many biological processes. In 1976, he identified a novel protein that bound to cyclic GMP, which was later purified and characterized as being a phosphodiesterase that degrades cyclic GMP. This enzyme, now known as PDE5, is the site of action of drugs used to treat erectile dysfunction. Dr. Corbin was a HHMI investigator for 17 years.

A mother's diet and metabolic status during gestation has been shown to affect her offspring's risk of developing metabolic disease later in life. In the Gannon Lab, I study the mediators of this increased disease risk using two animal models of maternal high fat diet during pregnancy. In a collaboration with multiple labs across the country, I obtain pancreata from non-human primates exposed to high fat diet in utero. Pancreatic endocrine cell mass, structure, and function are currently being investigated. In a mouse model, I study the effects of maternal high fat diet on the epigenetic profile of pancreatic beta cells in the offspring. Together, these studies will enhance our understanding of how high fat diet during pregnancy predisposes offspring to develop metabolic disease.

Our lab studies the function of potassium channels in electrically excitable endocrine cells within the pancreas. We are particularly interested in the β-cell specific potassium channel, TALK-1. TALK-1 is the most abundant potassium channel in the β-cell, and a polymorphism within TALK-1 has been associated with an increased risk for Type-2 diabetes. Our lab has previously shown that TALK-1 channels regulate the β-cells ability to release insulin in response to glucose. My work focuses on characterizing this regulation so that we can better understand the function that the channel plays in diabetes.

The very significant body of work performed by Dr. Hardman has contributed tremendously to our understanding of cyclic nucleotide synthesis and degradation. In particular much of the fundamental knowledge of guanylate cyclase and cyclic nucleotide phosphodiesterases, which synthesize and degrade cyclic GMP, respectively, is a result of Dr. Hardman’s research. In addition to his appointment in our department, Dr. Hardman was also Professor and Chairman of the Pharmacology Department from 1975 to 1990 and Associate Vice-Chancellor for Health Affairs at Vanderbilt until his retirement in 1997.
MD PhD Student, Winder laboratory, Molecular Physiology & Biophysics
Drug dependent patients trying to maintain abstinence often relapse to their chosen of drug of abuse, with many citing stress as an antecedent to use and a lack of effective treatment to control the urge to use. Guanfacine is an α2A-adrenergic receptor agonist that targets receptors for the brain stress neurotransmitter norepinephrine and has been used in both preclinical and clinical trials for addiction, often showing positive results such as reduced craving but not producing changes in ultimate rates of relapse. We hypothesize that the ineffectiveness on relapse is due to competition among the myriad effects of this drug and aim to study a non-canonical neuronal activating effect in the bed nucleus of the stria terminalis, an area of the brain known to be implicated in both stress and addiction disorders, through the complementary use of whole cell electrophysiology and neuroanatomical methods in the hopes that uncovering the mechanism underlying this effect will aid in future treatment of patients dependent on drugs of abuse.

Graduate Student in the Neuert Lab
The sequencing of genomes from many different organisms has shown that a large fraction of the genome is transcribed into RNA but does not code for proteins. Genome-wide studies have identified many long non-coding RNAs (lncRNAs), yet very little is known about their functions. The Neuert lab's previous studies have demonstrated that non-coding RNAs modulate the localization of key transcription factors, which influence the occurrence of downstream events that lead to active or silenced transcription. I will use a combination of quantitative single-molecule RNA experiments in single cells with genetic manipulations and single-molecule-based modeling to understand the molecular mechanism of transcriptional regulation of long non-coding RNAs in mammals to greater detail.

I have thus far determined that proper dosage of both Oc1 and Pdx1 is necessary for endocrine cell differentiation and that defects established during development persist into adulthood. I am further interested in identifying the direct targets of Oc1 during pancreas development since so little is known about its direct regulatory role.

Glaucoma is a major public global health problem accounting for vision loss and blindness in millions of people world-wide. Although glaucoma can be treated by lowering intraocular pressure with medications, laser treatments or surgery, most patients are unaware of decreased vision until advanced stages of the disease. Improved treatment for glaucoma patients requires better understanding of the disease mechanisms and development of early detection strategies. Our broad long term goals are to understand the disease pathophysiology and to identify genetic markers for early detection and better treatment of glaucoma.

In the past 20 years, two new mechanisms of hypertension have been defined: one is oxidative injury and the second is inflammation. Our lab has shown that dendritic cells (DCs) from hypertensive mice accumulate isolevuglandins that adduct to proteins and promote T cell activation. In hypertension, the endothelium is activated to produce reactive oxygen species and to express adhesion molecules and chemokines that attract inflammatory cells. In my project, we hypothesized that human endothelial cells exposed to mechanical stretch will promote conversion of human monocytes into activated DCs. Therefore, I study this conversion when monocytes co-cultured with human aortic endothelial cells exposed to either normal cyclical stretch (5%) or hypertensive cyclical stretch (10%) using the Flexcell® Tension System. I also study the different signaling molecules that could potentially be facilitating this process in hopes of understanding the mechanism of action.

Calcium/calmodulin-dependent kinase II (CaMKII) is a highly abundant serine/threonine kinase in the brain. Direct interactions between activated CaMKII and its substrates play a number of important roles within the cell such as feedback regulation of channels/receptors, and normal synaptic plasticity. Relatively few CaMKII-associated proteins are known to preferentially interact with inactive CaMKII, and their functional roles are poorly understood. Moreover, molecular mechanisms underlying the coupling of CaMKII to the G-protein coupled receptors (GPCRs) that stimulate the release of intracellular calcium are poorly characterized. An interaction between inactive CaMKII and the metabotropic glutamate receptor 5 (a Gq-coupled GPCR) was recently reported. I am currently investigating how CaMKII interactions with mGlu5 can change mGlu5 signaling. Understanding the physiological importance of this interaction may lead to novel treatments of neurological disorders linked to dysfunction of mGlu5 such as Parkinson’s Disease, addiction, schizophrenia, and autism spectrum disorder.

RNA Polymerase II transcriptional activation contributes importantly to the regulation of gene expression by controlling mRNA biosynthesis. A central driving force of the activation process is provided by the concerted action of a DNA-binding transfactor and at least one coactivator. I am interested in defining the transfactor-coactivator interactions required for activation. The specific goal of my current work in the Weil lab is to determine the specific domains the Rap1 transcriptional activator uses to interact with the general transcription factor TFIID to drive activation of the budding yeast S. cerevisiae ribosomal protein genes. I combine genetic, biochemical, and biophysical approaches to accomplish this goal.

Brain function relies on the formation and stabilization of synapses, and many neurological disorders are associated with disruptions in synaptic signaling. Scaffolding proteins play a critical role in maintaining spine morphology and bringing receptors and ion channels in close proximity to their downstream signaling molecules. In the Colbran lab, I study protein-protein interactions between CaMKII and scaffolds in the postsynaptic spines of neurons, and how they regulate downstream signaling. I am also interested in how neurons signal from the synapse to the nucleus in order to initiate gene transcription, an important process in learning and memory.

The research area pursued by Dr. Pilkis involved hormonal control of hepatic gluconeogenesis and glycolysis via alterations in enzyme activities. He discovered fructose-2,6-bisphosphate, the key allosteric modulator of phosphofructokinase and fructose-1,6-bisphosphatase, the bifunctional enzyme which synthesizes and degrades this regulator, and identified the gene that encodes this protein. This led to his extensive study of the hormonally-mediated regulation of the enzymatic activities of the bifunctional enzyme, including studies of its genetic expression. Dr. Pilkis became Professor and Chairman of Physiology and Biophysics at The State University of New York at Stony Brook in 1986.

Communication by HDL-miRNAs in Type 2 Diabetes
MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally repress gene expression and are found in both cells and extracellular fluids, including plasma. Extracellular miRNAs are protected from circulating nucleases through their association with lipid and protein carriers, specifically exosomes and lipoproteins.. Currently, I am studying the role of high-density lipoproteins (HDL)-miRNAs as cell-to-cell messengers in a novel endocrine-like communication pathway within Type 2 diabetes. We found that many of the most abundant miRNAs on HDL are also enriched in insulin-producing β-cells in the islets of Langerhans. Additionally, we found that the miRNA signature on HDL is significantly altered in rat models of Type 2 diabetes; therefore, the goal of my project is to investigate the molecular mechanisms by which the β-cell-originating miRNAs control gene expression in distal tissues and how this pathway regulates systemic lipid and glucose metabolism. Using high-throughput genomics, I aim to decode and control miRNA intercellular communication to better understand and treat type 2 diabetes, including developing biomarkers to predict pre-diabetes.

The prevalence type 2 diabetes (T2D) continues to increase worldwide. Multiple SNPs associated with altered risk of T2D have been identified through genome wide association studies including rs13266634 in the SLC30A8 locus, which encodes zinc transporter 8 (ZnT8). In addition, rare mutations resulting in SLC30A8 haploinsufficiency are protective against T2D. Using several mouse models, we are investigating the role that ZnT8 plays in beta cell function and the potential of ZnT8 as a therapeutic target for T2D.

Liver is a primary site of macronutrient metabolism. Obesity linked diseases of the liver such as nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) result in ECM expansion, defective hormonal responses, and disrupted transcriptional networks. Integrin receptors and their immediate post-receptor pathways convert sensory inputs from the ECM to biochemical processes within the cell. Altered expression of several integrin signaling components accompanies the metabolic dysregulation that occurs in high fat (HF)-fed mice. The mechanisms linking ECM expansion and integrin signaling to metabolic disease are a primary focus of our lab. My research utilizes hepatocyte specific knockout of several integrin signaling components (e.g. integrin α5, integrin β1, and Integrin-linked kinase) in mice to fully characterize these pathways and their involvement in pathologic responses of the liver to high fat feeding.

Short term goals include the characterization of microRNA regulatory modules controlling cholesterol biosynthesis. Moreover, we aim to determine i.) How microRNAs are selected and exported to HDL, ii.) How microRNAs are transported on HDL and altered in disease, and iii.) How microRNAs are transferred to recipient cells and regulate genes related to cholesterol and lipoprotein homeostasis.

The deterioration of pancreatic islet function is a hallmark of type 2 diabetes mellitus (T2DM). In the Jacobson lab, I study the physiological functions of an islet potassium channel, TALK-1. TALK-1 is the most transcriptionally abundant potassium channel in insulin-secreting β-cells, and polymorphisms in TALK-1 are associated with an increased susceptibility for T2DM. However, the molecular mechanisms underlying TALK-1’s contributions to T2DM pathogenesis remain unclear. Using a variety of experimental approaches, including electrophysiology, calcium imaging, hormone secretion, and mouse models, we have recently found that TALK-1 channels regulate islet calcium homeostasis and insulin secretion. These findings suggest that TALK-1 could serve as a therapeutic target in T2DM.

My project focuses on defining the molecular signatures defining islet dysfunction in recent-onset type 2 diabetes in human tissues. To do this, I am characterizing the functional, morphologic, and transcriptional profiles of islets from individuals with type 2 diabetes using a combination of human pancreatic tissue, isolated islets, and sorted islet cell populations. I am also investigating the source of amyloid heterogeneity in type 2 diabetic islets.

Extracellular microRNAs have been identified in plasma, and our laboratory has identified these extracellular microRNAs are carried by lipoproteins including high-density lipoprotein (HDL). The goal of our laboratory is to characterize the role of these extracellular microRNAs, particularly to elucidate whether extracellular microRNAs may function as a novel cell-to-cell communication pathway. Within cells, microRNAs are small non-coding RNAs that post-transcriptionally regulate gene expression. Specifically, I study the myeloid-derived microRNA, miR-223, to understand to what tissue and cell types receive microRNA-223 after being exported from myeloid cells. To do this, I utilize bone marrow transplants between wild-type and miR-223 knockout mice to restore or deplete the myeloid (miR-223 donor cell) population. After restoring or depleting the myeloid population (miR-223 donor cell) I examine variety of tissue types and pure cell isolations to map out the delivery of extracellular miR-223 in vivo. My second project focuses on the role of endothelial microRNAs in the progression of Chronic Kidney Disease-associated atherosclerosis. I have found that complexing two microRNA inhibitors to HDL, allows me to effectively reduce endothelial microRNA levels. The decreased microRNA levels result in a dramatic reduction in atherosclerosis in vivo, which may be mediated through altered FAM220a regulation of STAT3 activation causing less inflammation.

Impaired insulin-stimulated muscle glucose uptake is a hallmark of insulin resistance and Type 2 diabetes. Before insulin can stimulate the muscle to take up glucose, it must first cross the endothelial barrier that separates the plasma from the interstitial fluid that bathes myocytes. I have developed an intravital microscopy technique which allows us to directly visualize and quantitate the trans-endothelial efflux of insulin in skeletal muscle. I am using this technique to 1) determine the mechanism by which insulin crosses the endothelium (i.e. receptor-mediated transport or passive diffusion) and 2) determine if impaired trans-endothelial movement of insulin may contribute to muscle insulin resistance.
