Research Overview

My research is focused on gastrin mediated carcinogenesis and chemoprevention.

a) My primary goal is to understand the mechanisms by which gastric epithelial cells respond to small peptide hormones gastrin and pro-gastrin, and also to infection by Helicobacter pylori, a gram negative, microaerophlic, spiral shaped bacilli. Infection with Helicobacter pylori results in hypergastrenemia and gastric cancer.  We aim to determine the different gastrin-induced cellular signaling response in gastric and colon epithelial cells and its subsequent effects on the expression of proinflammatory gene COX-2 and IL-8 expression at the transcriptional and posttranscriptional levels.

b) Chemoprevention, to determine the signaling mechanisms by dietary phyto-chemicals inhibit the growth of colon and pancreatic cancer cells.
