Geraniin ameliorates cisplatin-induced nephrotoxicity in mice.

Geraniin, an active compound isolated from Geranium sibiricum, has been reported to have antioxidant and anti-inflammatory activities. The aim of this study was to investigate the protective effects of geraniin against cisplatin (CP)-induced kidney injury in mice. Geraniin was administrated for three consecutive days following CP (20 mg/kg) injection. The results showed that geraniin inhibited CP-induced kidney histopathologic changes, MDA, inflammatory cytokines tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) production in kidney tissues. Geraniin also inhibited CP-induced blood urea nitrogen (BUN) and creatinine production. Meanwhile, the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) decreased by CP were reversed by the treatment of geraniin. In addition, geraniin significantly inhibited CP-induced NF-κB activation in kidney tissues. Treatment of geraniin dosedependently upregulated the expression of Nrf2 and HO-1. The anticancer effects of CP were not affected by the treatment of geraniin. In conclusion, these results indicated that geraniin protected against CP-induced nephrotoxicity by inhibiting oxidative stress and inflammatory response.
