Lab Bios:
Rebecca Berdeaux (Principal Investigator): A native of Illinois, Rebecca completed a BS in the Biology Honors program at University of Illinois, Champaign-Urbana in 1997. She then pursued her love of cell biology and signal transduction through doctorate work in Molecular and Cell Biology at the University of California, Berkeley. Under the supervision of Professor G. Steven Martin, Rebecca studied the contribution of small GTPases RhoA and Ras to oncogenic transformation, actin remodeling and extracellular matrix degradation caused by the v-Src oncoprotein. After earning her Ph.D. in 2003, Rebecca’s research direction shifted to the study of cAMP-regulated signaling and transcription in metabolic organs with Dr. Marc Montminy at the Salk Institute for Biological Studies in La Jolla, CA. Here, Rebecca created the first transgenic mouse line expressing an inhibitor of the CREB transcription factor in skeletal muscle and showed that the CREB target gene SIK1 (salt inducible kinase 1, an AMPK-related kinase) has a protective effect on skeletal muscle cells. Rebecca and her colleagues at Salk demonstrated that SIK1 directly phosphorylates and inhibits class II histone deacetylases. In 2008, Rebecca moved to UTHealth to start an independent research lab as Assistant Professor of Integrative Biology and Pharmacology, where she and her team have used genetic mouse models to rigorously pursue an in-depth understanding of CREB and SIK1 regulation and function in skeletal muscle cells. The Berdeaux team created the first Sik1-floxed mouse as well as mice for tissue-specific expression of a tool GPCR (called Gs-DREADD) that allows activation of the cAMP pathway in specific cell types in vivo using inert ligands and non-invasive in vivo monitoring of CREB activation using firefly luciferase. The lab’s primary current research interest is in how the cAMP pathway and SIK1 regulate skeletal muscle glucose metabolism and stem cell-mediated regeneration, and the lab has been fortunate to receive generous federal and foundation grants to support these projects since 2011. Dr. Berdeaux was promoted to the rank of Associate Professor with tenure in 2015. Rebecca has been an active participant in the MD Anderson-UTHealth Graduate School of Biomedical Sciences and is currently the Director of the Graduate Program in Biochemistry and Cell Biology. She served as Vice-Chair of the 2018 Gordon Research Conference on Phosphorylation and G Protein-Mediated Signaling, which she will lead as Chair in 2020. Rebecca is also on national grant review panels, serving as a reviewer for the NIH and American Diabetes Association. Dr. Berdeaux is also an active lecturer in the McGovern Medical School first and second year curriculum, teaching skeletal muscle physiology, integrative physiology of type 2 diabetes and pharmacology of type 2 diabetes drugs. She has earned honors as a Dean’s Teaching Award recipient for several years, the recipient of the inaugural Norman Weisbrodt Award for Teaching in Physiology, and the Faculty Recognition Award for the Cell and Regulatory Biology Graduate Program.
Laura Bobart (Postdoctoral Fellow): Laura was born and raised in Bloomington, Indiana. She attended Purdue University for her undergraduate education and received a Bachelors in Biological Sciences and Chemistry in 2010. During this time, Laura cultivated an appreciation and passion for scientific research while participating in an extracurricular research program in the Human Motor Behavior Laboratory with Dr. Howie Zelaznik. Following the completion of her undergraduate studies, Laura moved to Baton Rouge, Louisiana to study in the Laboratory of Exercise Biochemistry under the guidance of Dr. Laura Stewart at Louisiana State University. Laura studied the role of vitamin D and exercise in mitigating the systemic inflammatory response associated with obesity in college aged females. She completed her Masters in 2012 and PhD in 2014, both in the fields of Exercise Physiology and Sport Nutrition. Prior to joining Dr. Berdeaux’s laboratory, Laura gained significant postdoctoral experience at Pennington Biomedical Research Center in the Laboratory of Nutrient Sensing and Adipocyte Signaling, under the tutelage of Dr. Tom Gettys. Laura’s work focused on several different projects, including the role of dietary methionine restriction on the increase in the hepatic hormone fibroblast growth factor-21 (FGF21) and how methionine restriction temporally controls the expression of this hormone. She also carried out a number of projects determining the tissue-specific actions of FGF21 during the dietary intervention of methionine restriction, and how the tissue specificity of FGF21 impacts metabolism. Laura was also involved in a number of studies investigating the optimal degree of restriction of the amino acids methionine and cysteine in the diet that would elicit the highest overall positive metabolic phenotype. Laura joined Dr. Berdeaux’s lab in August 2019 and is excited to begin investigating the role of skeletal muscle SIK1 expression and its effects on metabolism.

Mohammad Gareeb (Research Assistant II): Mohammad is an M.D. from Karachi, Pakistan. He obtained his Bachelor of Medicine, Bachelor of Surgery degree in 2015 and since then has been working towards securing a competitive residency all the while keeping his passion for research alive. For the past year he worked in a Cardiology division lab, where he trained and was part of some ground breaking research such as the use of drug loaded echogenic liposomes to better and more efficiently target atherosclerotic plaque. And now he is part of the Berdeaux lab stem cell team where he wishes to further his knowledge and experience in the field of research.
As you can see he is much better at writing bios than Chase.

Daniel Hancock (Research Assistant I): Daniel is currently a student at NYU: Tisch School of the Arts going into his final year. He has graduated from the Atlantic Acting School and is moving to Stonestreet Film & TV studios to continue pursuing a BFA in acting. Daniel rejoined the Berdeaux as a Research Assistant in June 2019 and has learned alot! For Example: Did you know that CREB is a site specific transcription factor that is regulated by hormones? What a crazy world we live in...
