Eric R Fearon, M.D., Ph.D

Emanuel N. Maisel Professor of Oncology,
Professor of Internal Medicine,
Professor of Pathology, and
Professor of Human Genetics
Molecular analysis of cancer pathogenesis; β-catenin-dependent Wnt signaling; transgenic and knockout mouse models of colon cancer; miRNAs and cancer; CDX2 homeobox gene function
The research in the Fearon laboratory seeks to address the means by which specific oncogene and tumor suppressor gene defects contribute to the pathogenesis of colon and other cancers and to develop novel strategies for early detection and treatment of colorectal carcinomas.
