Megalin blockade with cilastatin ameliorates multiple wasp sting-induced acute kidney injury in rats.

| Abstract |
Cilastatin has been shown to prevent various drug-induced nephrotoxicities and confer renoprotection in a mouse model of glycerol-mediated rhabdomyolysis-induced acute kidney injury (AKI). The present study aimed to investigate whether cilastatin attenuates wasp sting-induced AKI in rats. Male Wistar rats were divided into the control, cilastatin, AKI, and AKI + cilastatin groups. Nephrotoxicity was assessed using renal function, rhabdomyolysis (creatine kinase, CK) and intravascular hemolysis (lactate dehydrogenase, LDH) markers, and histological changes. In addition, tubular injury biomarkers, apoptosis, oxidative stress markers, complement C3 expression, and urine and blood myoglobin levels were examined. Compared with the control or cilastatin group, the AKI group showed significant histological damage, increased levels of CK, LDH, and creatinine, and increased mRNA expression of tubular injury biomarkers. Cilastatin ameliorated wasp venom-induced kidney injury by attenuating oxidative stress and apoptosis. Cilastatin also reduced C3 expression in the renal tubular cells. In addition, cilastatin reduced serum myoglobin levels and increased urine myoglobin concentrations. Therefore, megalin blockade with cilastatin attenuates wasp venom-induced AKI owing to its antioxidative and antiapoptotic properties.
