Chemotherapy-induced peripheral neuropathy (CIPN) is one of the adverse events associated with the anticancer drugs, however, almost available analgesic drugs lack efficacy against CIPN. Previously our results using medical database, FAERS, suggested that HMG-CoA reductase inhibitors (statins) have the potential to ameliorate oxaliplatin-induced peripheral neuropathy (OIPN). In this study, we elucidated the effect and mechanism of statins to OIPN model mice and PC12 cell. Three statins (simvastatin, atorvastatin, and rosuvastatin) could not show the therapeutic and preventive effects against oxaliplatin-induced cold allodynia. On the other hand, repeated orally administration of each statins ameliorate development of oxaliplatin-induced mechanical allodynia and significantly suppressed already established allodynia induced by oxaliplatin. A gene-related database revealed that the expression of glutathione S-transferase (GST) family members is regulated by statins. Decreased survival rate of PC12 cells by treatment of oxaliplatin was canceled cotreatment of each statin for 24 hours. Furthermore, cell protective effect of statin was disappeared transfection of gstmu1 siRNA into PC12 cells. These our results suggest that statins might be one of the novel supportive care, which have neuroprotective effect to OIPN.
