ABSTRACT
Nephrotoxicity is a major adverse reaction of cisplatin-based chemotherapy. Organic cation transporter 2 (OCT2) which is located on the basement membrane of human proximal renal tubules is responsible for the renal accumulation of cisplatin and its nephrotoxicity. This study aimed to investigate the protective effect of PPIs to CP-induced nephrotoxicity. Three kinds of PPIs including lansoprazole, omeprazole and rabeprazole (Rab) were co-administrated with CP to mice. In addition, OCT2-overexpressed HEK293, HK-2 and A549 cells were co-incubated with CP and PPIs. The results showed that PPIs can attenuate CP-induced increase of CRE, BUN and histological damage of kidney. Among the three PPIs, Rab was found with a superior protective effect. It significantly reduced the accumulation of CP in OCT2-overexpressed HEK293 cells and in the renal cortex tissues of mice, but not in HK-2 cells. Moreover, Rab reduced the expression levels of cleaved-caspase-3, RIPK1, RIPK3, MLKL and p-MLKL and the apoptosis rate of renal tubular cells induced by CP in vivo, but not in HK-2 cells. However, Rab increased the viability of CP-treated cells in a concentration-dependent manner and attenuated CP-induced apoptosis and necroptosis in OCT2 over-expressed HEK293 cells. Finally, we demonstrated that Rab have no influence on the antitumor effect of CP. In conclusion, Rab attenuate CP-induced nephrotoxicity mainly through inhibiting OCT2-mediated CP uptake, without interfering with its anti-tumor property of inducing apoptosis and necroptosis.
