Abstract:
Objective To explore the effects of Dimethyloxalyl Glycine(DMOG)on isehemic acute renal failure(iARF)in mice and its relationship with activation of hypoxia inducible factor 1α(HIF-1α).Method Twenty five C57/BL male mice were divided into 5 groups randomly:control group,DMOG group,sham operation group,ischemia/reperfusion(I/R)group and DMOG pretreated group(DMOG+I/R).Ischemia/reperfusion injury was induced in mice by clamping both renal pedicles for 30 minutes.The expression of HIF-1α was determined by Western blot.Renal function was reflected by blood urea nitrogen(BUN)and serum creatinine(Scr).Morphologic changes were evaluated under light microscopy.Apoptosis in the kidney was detected by TUNEL staining.Expression of Vimentin,a marker of tubulointerstitial damage was detected by immunohistochemistry.Results The elvated levels of of BUN((65.8±2.6) vs (13.6±0.7),P＜0.01],and Scr[(229.5±11.2) vs (6.5±0.8),P＜0.01]andwere found morphological injury were induced by the ischemic insult in I/R group.Administration of DMOG dramatically improved renal function[BUN,(26.3±6.5)vs(65.8±2.6);Scr,(27.0±14.1)vs(229.5±11.2),P＜0.01]associated with amelioration of tubulointerstital damage.In the DMOG treated group,the protein level of HIF-1α in the kidney of mile was also up-regulated significantly.Conclusions The protection against iARF in mice by DMOG administration is mediated by activation of HIF-1α.
