Research Interests:

To elucidate post-receptor signaling that results in bile acid-induced colon cancer cell proliferation, we use cell culture, immunoblotting, radioligand binding, cell growth, cytotoxicity and apoptosis assays to determine the molecular mechanisms underlying bile acid effects in vitro on human colon cancer cell lines and in vivo on transgenic mouse intestine.
