| Research Abstract |
Dimethylarginie dimethylaminohydrolase (DDAH) degrades asymmetric dimethylarginine (ADMA), an endogenous nitric oxide (NO) synthase inhibitor, and comprises 2 isoforms, DDAH1 and DDAH2. To investigate the in vivo role of DDAH2, we generated transgenic mice overexpressing DDAH2. The transgenic mice manifested reductions in plasma ADMA and elevations in NO levels. In addition, TG mice also showed that DDAH2 induced pancreatic insulin secretion through increasing local NO production and reducing ROS levels in diabetic condition.
