Dr. Bailey joined The University of Texas Medical School-Houston in September of 2014 as an Assistant Professor in the Department of Internal Medicine, Division of Gastroenterology, Hepatology and Nutrition. She joins the department after completing her postdoctoral fellowship at Johns Hopkins University.
Dr. Jennifer Bailey earned her B.S. in Molecular Biology from the University of Nebraska-Lincoln in 2002, where she studied the role of algal lipopolysaccharides on the innate immune system in the Laboratory of Professor Ted Pardy. As an undergraduate student she also worked with Professor Bill Tapprich at the University of Nebraska-Omaha, where she studied the RNA structure of viral IRES elements and completed her M.A. in Biochemistry in 2004. While completing her degree, she was accepted as a summer fellow at the National Institutes of Health where she worked in the lab of Dr. Steven Jacobson. She then went on to pursue her Ph.D. in Cancer Research from the Eppley Institute at the University of Nebraska Medical Center in the Laboratory of Professor Tony Hollingsworth. Her dissertation work focused on mechanisms regulating pancreatic cancer progression and metastases. This research effort included the fundamental observation that hedgehog ligands regulate desmoplasia in pancreatic cancer.
After completing her Ph.D. in 2009, she moved to Johns Hopkins University School of Medicine to continue her work in pancreatic cancer. She joined the laboratory of Professor Steven Leach and studied mechanisms regulating pancreatic cancer regeneration and early neoplasia. Notably, during her postdoctoral studies, Dr. Bailey identified a putative cancer stem cell population present in preinvasive pancreatic cancer that has a gastrointestinal “tuft” cell morphology and is marked by Dclk1 and Acetylated α-tubulin. She received an F32 Individual Postdoctoral Award from the National Cancer Institute to fund her work, and in 2011, Dr. Bailey was awarded the Pancreatic Cancer Action Network/AACR Pathway to Leadership Award.
She is a member of the American Association for Cancer Research, where she previously served on the Associate Member Council, the American Gastroenterological Association and the American Association for the Advancement of Science.
The overall research program in the Bailey Lab is centered on understanding the biology of precancerous and cancerous lesions in the gastrointestinal system, with a focus on the molecular processes that regulate the transition from normal epithelium to cancer. For a number of years, we have employed lineage-tracing techniques to study stem cells and cells of origin in genetically engineered mouse models. In addition, we use these models to understand chronic inflammatory processes that increase the risk for the accumulation of oncogenic mutations in the pancreatic epithelium. There are a number of funded projects in the lab related to these ideas, and our overall goal is to better define therapeutic strategies for the personalized treatment of pancreatic and other GI malignancies.
Three main ideas underscore the work the Bailey lab: 1) To identify the genetic, epigenetic, whole transcriptome, and paracrine signaling events that regulate epithelial regeneration and transformation. 2) To better understand the genetic and epigenetic processes that regulate cellular plasticity. 3) To identify the genetic and epigenetic events that regulate how different cell types respond to the accumulation of mutations that drive neoplastic progression.
We comprehensively use genetic mouse models, cell culture and human tissue specimens to address a number of targeted hypotheses related to these main goals. We are enthusiastically expanding our translational research efforts and collaborations within the Texas Medical Center Digestive Disease Center, The Ertan Digestive Disease Center and the Department of Surgery.
