Dr. Goretsky received her MS degree from Lomonosov (Moscow State) University and Ph.D. from Russian Academy of Science. She worked as a postdoctoral researcher at the University of Chicago in and at Northwestern University. Currently she is working as a Assistant Professor in the Department of Internal Medicine, Division of Digestive Diseases and Nutrition of the University of Kentucky at Lexington. She has extensive experience in the biochemical analysis of both human and mouse intestinal crypt cell populations. She was studying a controversial role of nicotine in the origin and progression of ulcerative colitis and Chrons disease. She has interest in epigenetic regulation of β-catenin signaling.
Inflammation induced intestinal stem cells activation. β-catenin signaling and post-translation modifications. Origin and progression of the inflammatory bowel disease.

Research Interest

Her research interests include: Interrogate the role of β-Catenins post translation modifications in transcriptional activation of intestinal epithelial stem cells.

Scientific Activities

She is working to evaluate a role of TNF-induced PI3K (p85α) signaling in nuclear translocation of β-catenin in colitis and colon cancer.
