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.
