Oligomycin, an F1Fo-ATPase inhibitor, protects against ischemic acute kidney injury in male but not in female rats.

We investigated the effects of oligomycin, an F1Fo-ATPase inhibitor, on ischemic acute kidney injury in male and female rats. Ischemic acute kidney injury was induced by clamping the left renal artery and vein for 45 or 60 min followed by reperfusion, 2 weeks after contralateral nephrectomy. Renal dysfunction and histological renal damage were observed 1 day after reperfusion in both male and female rats, although these renal injuries were more marked in male rats than in female rats.

Sex difference in ischemic acute renal failure in rats: approach by proteomic analysis.

It is known that female rats are resistant to ischemic acute renal failure (ARF), compared with male rats. To elucidate sex differences in ischemic ARF, we searched global protein expression in post-ischemic kidneys using proteomic techniques. Ischemic ARF was induced by 45-min ischemia followed by reperfusion.
