  • Research

    Diabetes and obesity have both reached epidemic proportions in the United States. It is becoming urgent to elucidate the pathological mechanisms of these health problems. Improper gene regulation by transcriptional and epigenetic factors critically involves in the pathogenesis of these metabolic diseases. Dr. Dong's laboratory investigates two key families of factors that are emerging as critical regulators in nutrient and energy homeostasis - FOXO transcription factors and nuclear sirtuins (SIRT1/6). FOXOs are key players in the downstream of insulin signaling and regulate glucose and lipid homeostasis. SIRT1 and SIRT6 are both NAD-dependent histone deacetylases and modulate chromatin stability and dynamics. We have characterized several crucial FOXO target genes including Nr0b2 (SHP), Nampt, Srebp2, Pcsk9, and Sesn3, in the regulation of glucose and lipid metabolism and insulin sensitivity. Our research goal is to utilize the state-of-the-art technologies including genomics, epigenomics, proteomics, metabolomics, high-resolution imaging, and genomic editing to elucidate molecular and pathophysiological mechanisms underlying diabetes, obesity, and fatty liver disease and develop therapeutics for these disorders.

  • Clinical Interests

    Dr. Dong also has interests in human diabetes and fatty liver disease and their pathogenesis and clinical treatment. Precision medicine can be applied to these diseases to promote better diagnosis and therapeutic treatment.
