Research Interests

• Oncogenes, tumor suppressor genes, moleculat genetics of GI cancers (colon, pancreatic, upper GI)

Key words: Cancers: esophageal, pancreatic, colon. Oncogenes: EGFR, cyclin D1, Ki-Ras. Organotypic culture

Description of Research

Our laboratory has had long-standing thematic interests in the cell-type and tissue-type specific actions of certain oncogenes (cyclin D1, Ki-Ras, EGFR) and tumor suppressor genes (p53, p16INK4a) 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 geneticaly-engineered mouse models to investigate molecular mechanisms. These projects are translated into the objectives of improving molecular diagnostics and experimental therapeutics in patients.

Our research is funded through an NCI program project entitled "Mechanisms of Esophageal Carcinogenesis", NIH R01 grant on pancreatic cancer, and NIH R01 grant on colon cancer. Students and postdoctoral fellows are supported in didactic venues and conferences, present at national meetings, and have obtained national grant fellowships when applicable.

Rotation Projects

1. To understand the role of oncogenes (EGFR, cyclin D1, Ras) and tumor suppressor genes (p53, p120catenin) in the tumor microenvironment as they relate to tumor cell migration and invasion in GI cancers, using organotypic culture and mouse models.
2. To define mechanisms underlying cell lineage during pancreatic development and cancer.
3. To functionally characterize novel suppressor genes in colon and breast cancers.
4. To functionally characterize stem cells in the upper GI tract.
