Research

Our lab is interested in posttranslational modifications (PTMs) of transcription factors in the pathophysiology of diabetes and obesity, and their associated comorbidities, including hepatic steatosis, cancer and cardiovascular diseases. In particular we focus on: 1) The transcriptional selectivity of PPARγ determined by PTMs in regulating adipose plasticity, including adipogenesis, browning, senescence, adipokine production, lipid and glucose metabolism. We aim to understand the fundamental mechanism in remodeling adipose tissues and provide new strategy to develop the next generation drug for treating Type 2 Diabetes. 2) The novel connection between obesity and aging. Obesity and aging go hand in hand and share similar metabolic derangements. Given that adipose tissue is a driver of aging, the lab aims to mechanistically address the shared metabolic changes in obesity and aging from an adipose perspective. This question is crucial, both scientifically and clinically, for curbing metabolic decline and thereby maximizing human healthspan.

Research Interests

  • Insulin resistance, diabetes and atherosclerosis
  • Lipid metabolism and cancer
  • Metabolic syndrome and aging
  • obesity and adipocyte biology
  • Posttranslational modifications (PTMs), acetylation, SirT1
  • The selective regulation of PPARgamma and nuclear receptor
