Abstract:
Objective To investigate the expression of livin of kidney tissues in rats with acute kidney injury (AKI) induced by endotoxin ,and the role of livin in the cell apoptosis of AKI .Methods The rat models with AKI were induced by endotoxin .The de-gree of kidney injury was observed by hematoxylin and eosin stain ,measuring the levels of the serum creatinine and urea nitrogen . The expression of livin and caspase-3 in kidney tissue at different time points was analyzed by immunohistochemistry assay ,and the relationship between the expression of livin and caspase-3 and kidney injury was analyzed .Results Compared to the control group , the rats injected endotoxin had the performance of AKI ,with obviously pathomorphological damage in the kidney tissues ,signifi-cantly increasing in the serum creatinine and urea nitrogen (P<0 .01) .The livin and caspase-3 of kidney tissues in rats with AKI caused by endotoxin were positive expression (P<0 .01) .With the lapse of time ,the trend of increasing of caspase-3 showed gradu-ally slow after the highest expression of livin .Conclusion The livin involved in the pathogenesis of endotoxin-induced AKI ,it might relieve the kidney injury and protect renal function by inhibiting casepase-3 important apoptotic effector protein .
