Research Expertise

Current research projects are aimed at elucidating the cellular and molecular basis of liver growth and development. Specifically my laboratory is focused on elucidating roles of signaling mechanisms such as Wnt/β-catenin, PDGFR and other receptor tyrosine kinases in prenatal and postnatal liver development, liver regeneration after partial hepatectomy or after toxic liver injury. The laboratory is focused on elucidating mechanisms to enhance liver regeneration using modulation of specific signaling pathway. In addition, studies in the lab are ongoing to elucidate mechanisms of repair through hepatic progenitors. Specifically, using models such as DDC injury and bile duct ligation, we are interested in understanding the relevance of specific signaling pathways that induce the ductular reaction and expansion to ultimately promote repair of the damaged liver. Similarly, the lab is also focused on studying pathways that may be exploited to retard hepatic injury or facilitate repair using various preclinical models such as Fas or LPS that mimic clinical diseases such as viral, autoimmune or alcoholic hepatitis. There is ample evidence generated in our lab that pathways such as Wnt/β-catenin signaling may be key regulators of hepatic metabolism as well as injury and thus their modulation can be exploited to benefit repair process due to their divergent effects. Current studies are thus also aimed at understanding the role of -catenin signaling in the metabolism of cholesterol, vitamin C, and bile acid in the liver. The last major interest of my laboratory is to understand the cellular and molecular basis of HCC for therapeutic and prognostic purposes through utilization of animal models of cancer and patient tissues. Again, we have identified key signaling mechanisms that are being characterized for their functions at multiple levels in HCC pathogenesis. Special emphasis is on targeting pathways such as Wnt/β-catenin, PDGFRα, EGFR and Met for treatment of HCC through use of existing and novel inhibitors, either alone or in combinations.
