Research Interests:

Research in my lab examines the molecular mechanisms underlying links between obesity, adipocytokines and carcinogenesis. We have established from our previous studies leptin and adiponectin, play very critical roles in liver fibrosis and carcinogenesis. Leptin is found to be pro-fibrogenic and pro-cancerous while adiponectin has been found to have quite opposite effect. Adiponectin is inversely correlated with the various consequences of obesity including cancer.
