Our group has made key contributions to the understanding of chronic liver disease. Selected projects (as corresponding author):

 

• Posttranscriptional reprogramming of metabolism is a driver of hepatic stellate cell activation in liver fibrosis (Gastroenterology 2020)
• Adaptive translational response to ER stress mediated by CPEB4 counteracts hepatic steatosis (Nature Cell Biology 2017)
• Vascular stem cells mediate a new mechanism responsible for formation of abnormal vessels in chronic liver disease (Gut 2017)
• CPEB proteins are critical for pathologic angiogenesis in chronic liver disease (Gastroenterology 2016)
• Endogenous angiogenesis inhibitors have potent antiangiogenic and antifibrogenic therapeutic activity in chronic liver disease (Gut 2015; Hepatology 2014)
• Angiogenesis is a critical hallmark of chronic liver disease with therapeutic potential (Journal of Hepatology 2010; Journal of Hepatology 2009; Hepatology 2009; Gut 2007; Hepatology 2007; Journal of Hepatology 2006; Journal of Hepatology 2005; Gastroenterology 2004; among many others)
