讲座内容简介

 Metforministhe first-line therapy for type 2 diabetes (T2D) worldwide and has ability to treat patients with Polycystic Ovary Syndrome (PCOS). Molecular or genetic mechanisms responsible for occurrence of these metabolic diseases are largely unknown. Although metformin has been long used in clinic, its mode of action also remains elusive. The ultimate goal of our research is to unveil the machineryorthe most fundamental biology underlying occurrence of these metabolic diseases through better understanding on how metformin works.

During the talk, our recent progress on achieving the central aimswill bepresentedand discussed. Conclusively, 1) out of forward genetic screen, we identified five genes working in the same pathway to generate lysosome related organelles, which can mimic effect of metformin when mutated inC. elegansand mice; 2) a feasible genetic model for PCOS study in nematode animals is proposed, within which metformin and its mimicker tryptophan can rescue worms’ PCOS-like phenotypes; 3) chemical genetics is applied to develop better options than metformin for T2D and PCOS treatment, the rational and approaches for which will be delivered.
