RESEARCH

Adiponectin is a hormone secreted from adipose tissue. The serum concentration of adiponectin is significantly reduced in type 2 diabetic and obese patients. A number of studies have shown that adiponectin is an insulin sensitizer by enhancing insulin sensitivity, suggesting that the molecules in adiponectin signal pathways could be targets of therapeutic drug development for the treatment of type 2 diabetes and obesity. However, the molecular mechanism governing adiponectin action is largely unknown. Our research interest is mainly focused on: 1) the elucidation of the molecular pathway(s) mediating adiponectin signaling in cells and in vivo; and 2) the investigation of the molecular mechanism of the cross-talk between insulin signaling pathway and adiponectin signaling pathway.
