Our research is focused on RNA-binding proteins and their physiopathological roles. An understudied aspect of human disease is gene regulation by modulation of mRNA function. In our research lab we investigate functional connections between the RNA-binding protein Zinc Finger Protein 36 Like-2 (ZFP36L2 or L2) and human diseases. L2 is a member of the Tris-Tetra-Proline or Zinc Finger Protein 36 (TTP/ZFP36) family of RNA-binding proteins that bind Adenine-uridine-Rich Elements (AREs) in the 3’ untranslated regions of target mRNAs. Upon binding, L2 accelerates mRNA target degradation and/or inhibits mRNA translation, ultimately decreasing the protein encoded by the L2-target mRNA.

We have three particular goals:

  • Determine new specific L2-mRNA targets involved in human diseases.
  • Determine the mechanism(s) by which L2 modulates these novel RNA targets.
  • Determine the physiological consequences of L2 ablation in specific cells types using mouse models and CRISPR/Cas9-mediated knockout system.

Overall goal of our research is to gain better knowledge of gene-gene and gene-environment interactions in common cardiovascular conditions in humans. We have been modifying mouse genome in such a way that resulting mice can model quantitative variations of a specific gene product that occur in human population. With these mice, we explore causes, mechanisms, and nutritional treatments of cardiovascular complications resulted from common conditions such as diabetes, lung infections, and pregnancy-associated hypertension. Current focus is on the oxidative stress and effects of vitamin B12 as antioxidant and beyond.

My research aims to understand the pathogenesis and host immune response to emerging and re-emerging viral infections, including encephalitic alphaviruses such as chikungunya virus and respiratory coronaviruses such as SARS-CoV-2. Other areas of interest include examination of genetic and environmental factors that influence the response to infection and disease outcome, evaluation of vaccines and novel therapeutics against emerging viruses, and development and optimization of animal models of infectious disease.

My research lab focuses on the molecular pathogenesis of endometrial cancer, the most common gynecologic cancer in the Western world. Current projects include developing molecular diagnostics for predicting endometrial cancer histotype, stage, and recurrence; developing clinical and lab-based algorithms for the identification of patients with hereditary endometrial cancer (Lynch Syndrome); discovering novel molecular mediators of endometrial cancer invasion and metastasis; identifying signaling pathways important in the pathogenesis of endometrial cancer; and identifying molecular determinants of health disparities in endometrial cancer.

The Button lab in the Department of Biochemistry and Biophysics is part of the Marsico Lung Institute. Our lab is actively involved in projects that are designed to define the pathogenesis of muco-obstructive pulmonary disorders and to identify therapies that could be used to improve the quality of life in persons afflicted by these diseases. In particular, our research works to understand the biochemical and biophysical properties of mucin biopolymers, which give airway mucus its characteristic gel-like properties, and how they are altered in diseases such as Asthma, COPD, and cystic fibrosis.

The main goal of the Nagarajan lab research program focuses on how the innate branch of the immune system regulates adaptive immunity, as it relates to the pathogenesis of autoimmune disease such as lupus or rheumatoid arthritis (RA)-induced cardiovascular disease.   IgG-Fcgamma receptor (FcgR)-mediated signaling is critical for mediating host defense against infectious disease, but they also mediate disease pathology in autoimmunity and atherosclerosis. Specifically, we are studying the role of IgG-Fcgamma receptor (FcgR) signaling network in innate immune cells activation that contributes to autoantibody production and T cell subset activation associated with autoimmune, and cardiovascular diseases.  We are using a repertoire of relevant knockout mouse and humanized FcgR mouse models to address the questions of how FcgR-mediated signaling promotes autoimmune disease-induced atherosclerosis. As a translational component, we are collaborating with rheumatologists and cardiologists to analyze changes in innate and T cell subsets in patients with lupus or RA, who has premature atherosclerosis.

Tissue development and homeostasis depend on the precise coordination of self-renewal and differentiation programs. A critical point of regulation of this balance is at the level of cell division. In the Williams lab, we are interested in stratified epithelial development, stem cells, and cancer, with a particular interest in how oriented cell divisions contribute to these processes. Asymmetric cell divisions maintain a stable pool of stem cells that can be used to sustain tissue growth, or mobilized in response to injury. However, dysregulation of this machinery can lead to cancer, particularly in epithelia where tissue turnover is rapid and continuous. Using the mouse epidermis and oral epithelia as model systems, we utilize cell biological, developmental and genetic approaches to study the molecular control of oriented cell divisions and mitotic spindle positioning, and how division orientation impacts cell fate choices in development, homeostasis, injury, and disease.

A critical component of airways innate defense is the thin liquid layer lining airway surfaces, the periciliary liquid (PCL), that provides a low viscosity solution for ciliary beating and acts a lubricant layer for mucus transport. Normal airways appear to be able to sense the PCL volume and adjust ion channel activity accordingly. The long term goal of this laboratory is to understand how homeostasis of PCL volume occurs in airway epithelia under normal and pathophysiological conditions. Currently, research in the Tarran lab is focused on three main areas: 1) Regulation of epithelial cell function by the extracellular environment, 2) Gender differences in cystic fibrosis lung disease and 3) The effects of cigarette smoke on epithelial airway ion transport. We utilize cell biological and biochemical techniques coupled with in vivo translational approaches to address these questions.

We study host defense mechanisms in the lungs, particularly the inflammatory and innate immune processes important in the pathogenesis and course of bacterial pneumonia, acute lung injury/acute respiratory distress syndrome, and cigarette smoke-associated lung disease. Basic and translational studies address mechanisms of host defense, including recruitment and function of leukocytes, vascular permeability leading to edema, bacterial clearance and resolution.  Cell signaling pathways initiated by binding of leukocyte-endothelial cell adhesion molecules and molecular mechanisms underlying the functions of neutrophils are two particular areas.
