Senior Research Assistant, Center for Translational Research
I. DEPARTMENT INFORMATION
Job Description Summary:
GW’S Center for Translational Medicine and Department of Surgery conducts innovative, fundamental basic science research. Our clinical and research interests have been to develop effective therapeutics targeting liver and gastrointestinal (GI) cancers with a focus on the TGF-Beta signaling pathway and its target genes as well as CEACAMs. We identify and validate tissue and blood-based combinatorial biomarker panels, derived from functional pathway-specific studies, to improve the early detection of liver and GI cancer as well as stratify populations according to their risk for developing cancers.
Over the past ten years, we have developed integrated approaches—combining bioinformatics analysis with in vivo mouse models, and in vitro biological and biochemical methods—to identify and validate the relevance of TGF-Beta-Smad3 signaling in liver and GI cancer. Alcohol-induced liver damage remains a major health issue and liver cancer is the leading cause of cancer-related death worldwide. We have revealed that TGF-Beta mutant mice are highly sensitive to the toxic effects of alcohol, and develop liver cancers. We hypothesize that TGF-Beta deficient mice resulting from Smad3 and Beta-2SP defect with impaired expression of key genes involved in DNA repair (FancD2), chromatin modulation (CTCF and Sirtuins) and stem cell homeostasis, are susceptible to alcohol-induced liver inflammation, injury, and cancer. We will test mechanisms by which the tripartite complex of CTCF, Smad3 and Beta-2SP regulates FancD2 expression and other targets, stem cell homeostasis in the liver, and the response to liver injury induced by alcohol, DEN and high fat diet. We will use a variety of in vitro molecular biological assays as well as transgenic mouse models to test our hypothesis and explore the underlying mechanism.
The Center is searching for a full-time Senior Research Assistant. This position aids the current researchers (Postdoctoral Scientist, Research Scientists and/or Lab Manager) in planning, executing, and analyzing biochemical, biological and microbiology experiments in the context of early detection of liver cancer and alcohol-induced liver damage experiments. The RA conducts experiments under the direct supervision of the Assistant professor/lab manager and receives mentoring and direct guidance from the Principal investigator in order to advance their career in academic research.
