Description of Research Expertise

Oncogenes, tumor suppressor genes, tumor microenvironment, tumor metastasis, molecular genetics of GI cancers (colon, pancreatic, upper GI)

Description of Other Expertise

Our laboratory has had long-standing thematic interests in the cell-type and tissue-type specific actions of certain oncogenes (cyclin D1, EGFR) and tumor suppressor genes (p53, p120 catenin) in modulating the initiation, progression and invasion of gastrointestinal cancers, especially upper GI, pancreatic and colon. To that end, we employ novel three-dimensional cell culture systems (mouse and human origins) and genetically-engineered mouse models to investigate molecular mechanisms. These projects are translated into the objectives of improving molecular diagnostics and experimental therapeutics in patients.
