Research Synopsis

My lab is interested in defining the signaling pathways which control cAMP mediated cytoprotection in hepatocytes. During many forms of liver disease bile formation is slowed and hepatocytes retain many endogenous toxins including bile acids. Bile acid retention leads to hepatocyte apoptosis and necrosis. We have discovered that pre-treatment of hepatocytes with agents that increase intracellular cAMP protect hepatocytes from the cytotoxic action of bile acids. We have conducted experiments to show that this protection is mediated by a signal transduction pathway that involves cAMP activation of cAMP-GEFs rather than the activation of the classic cAMP/protein kinase A pathway. We are currently characterizing the downstream mediators of this cAMP-GEF pathway. Presently we know that it involves sequential activation of the nonreceptor tyrosine kinase, Src tyrosine kinase, the lipid kinase, phosphoinsitide -3-kinase and the serine/threonine kinase, Akt.
