However, in an in vivo study performed in diabetic rats with brain ischemia, the anti-oxidant effects of liraglutide treatment (i.e., increased SOD and reduced myeloperoxidase levels) were mediated by activation of the mitochondrial ATP-sensitive potassium channel composed of sulfonylurea receptor 1 (SUR1) and the K+-selective inward rectifier Kir6.2 [90]. The gene discussed is MPO; the disease is brain ischemia.
