英文摘要
Hypoxia induced mitochondrial oxidative stress in renal medullary thick ascending limb of loop of Henle. Treatment with Mito-TEMPO significantly attenuated the reduction of renal medullary blood flow induced by ischemia/reperfusion. We established methods to evaluate renal function with [^<15>O]H_2O-PET and [^<18>F]FRP-170-PET. We created conditional prolyl hydroxylase (PHD) knockout mice, and measured the response of renal medullary blood flow in those mice. These results indicated that hypoxia could exacerbate renal injury though increase of mitochondrial oxidative stress and following reduction of renal medullary blood flow.
