Research Interests:

1. Nuclear receptors and transcriptional factors in the pathogenesis of nonalcoholic fatty liver disease (NAFLD)
NAFLD is becoming a major health concern worldwide. The mechanisms underlying the pathogenesis of NAFLD and disease progression from nonalcoholic fatty liver (NAFL; steatosis without hepatocellular injury) to the more aggressive nonalcoholic steatohepatitis (NASH; steatosis and inflammation with hepatocyte ballooning, with or without fibrosis) remain poorly understood. Exosomes are 50–150 nm vesicles secreted by cells and involved in cell-to-cell communications by transferring signaling molecules. Our recent study interestingly showed that disrupting nuclear receptor small heterodimer partner (Nr0b2, SHP), a critical transcriptional regulator of liver metabolism, activates RNA-binding protein and promotes exosome-mediated stress signaling transduction from hepatocytes to macrophages, exacerbating disease progression from NAFL to NASH. The goal for our research is to understand how nuclear receptors and transcriptional factors regulate stress signals transduction inside and outside of cells during metabolic adaptation and metabolic disease. Our ultimate goal is to develop novel approaches to remodel maladaptation in metabolic disease for therapeutic intervention of NAFLD.

2. RNA-binding protein HuR-mediated signaling in liver carcinogenesis
Hepatocellular carcinoma (HCC) is the major histological type of liver cancer and the second leading cause of cancer mortality worldwide. Our long-term goal is to define the molecular mechanisms underlying hepatocarcinogenesis and develop novel strategies for HCC prevention and treatment. HCC arises exclusively on the background of chronic liver injury and inflammation. Thus, targeting key genes that regulate both inflammation and oncogenic pathways in HCC is an attractive therapeutic approach. RNA-binding protein Hu Antigen R (HuR) controls mRNA turnover and translation of numerous genes involved in inflammation and oncogenic pathways. Our recent study showed that HuR is elevated and activated in human HCC and in mouse HCC developed in Shp-knockout liver. Using a combination of genetic and therapeutic approaches, we are testing our hypothesis that HuR acts as a tumor promoter driving liver carcinogenesis, while HuR-targeted intervention is a novel therapeutic strategy for HCC.
