Title: The Vitamin E Derivative, ESeroS-GS, Attenuates Renal Ischemia-Reperfusion Injury in Rats
Abstract: Background Acute kidney injury (AKI), which occurs during renal transplantation and cardiovascular surgery, is a major clinical problem associated with high mortality, and has limited treatment options. Anti-inflammation therapy has been suggested to improve the course and outcome of AKI. In this study, we hypothesized that ESeroS-GS, a vitamin E derivative, inhibits cytokine production and prevents renal ischemia-reperfusion (I/R) injury in rats. Methods Rats received an intravenous infusion of ESeroS-GS or saline, and underwent experimentally-induced renal I/R injury or sham treatment. Rats were sacrificed after 60 min of ischemia and 24 h of reperfusion. To evaluate the renal protective effects of ESero-GS, renal function was examined, kidneys were histologically assessed, levels of myeloperoxidase (MPO) and serum cytokines were measured, and caspase 3/7 activity was determined. Results ESeroS-GS attenuated I/R-induced histologic alterations, reduced levels of MPO and serum BUN, Cre, TNF-α, and IL-6, and decreased caspase 3/7 activity in kidneys of rats subjected to renal I/R injury. Conclusions ESeroS-GS attenuated renal injury after I/R by reducing serum cytokine levels. Our findings suggest that ESeroS-GS may have therapeutic potential against various human I/R conditions.
