RESEARCH INTERESTS

My laboratory investigates the molecular and cellular mechanisms regulating liver growth in both physiological and pathological conditions. The maternal liver adapts to pregnancy by marked growth manifested by liver cell proliferation and liver size increase. We are particularly interested in revealing the roles of placental hormones in mediating maternal hepatic adaptations to pregnancy. The liver exhibits robust regenerative responses to acute or chronic liver injuries to restore the lost liver mass and regain original hepatic structure and function, which is a phenomenon of compensatory growth of injured liver. Timely and/or enhanced liver regeneration leads to recovery from liver injury and survival, whereas delayed and/or inhibited liver regeneration results in liver failure and death. We are studying the regulation of hepatocyte proliferation and liver stem/progenitor cell behaviors during pregnancy and liver regeneration. Our goal is to develop a clinical strategy to rescue injured livers by targeting liver repair.
