However, its clinical application is very limited due to its severe toxic efects. The present study aimed to reveal the efects of NAC, which exhibits broad biological activities in reducing CP-induced liver damage, in consideration of biochemical, genetic, and histopathological fndings. Twenty-eight wistar rats were randomly divided into four groups of seven animals. A dose of saline was administered (i.p.) to the control group for 5 days. One dose of NAC (200 mg/kg) was administered to the NAC group for 5 days (i.p.). To the NAC + CP group, a dose of CP (7.5 mg/kg) was administered on days 2 and 5 of the experiment, a dose of NAC (200 mg/ kg) (i.p.) was administered for 5 day of the experiment. CP (7.5 mg/kg) was administered to the CP group on days 2 and 5 of the experiment. At the end of the experiment, the biochemical, histological, and mRNA expression analyses of the liver tissues isolated from all the rats were performed. A statistically signifcant decrease was observed in the AST and ALT enzyme activities in Group NAC + CP compared to Control and CP groups. In addition, it was determined that the NAC administration reduced CPinduced infammation by increasing the level of NF-κB and decreased CP-caused oxidative stress by decreasing the GPx level. Moreover, the histopathological analyses showed that NAC improved liver morphology. It was revealed by Western blotting analysis that NAC promoted Bcl-2 signaling and decreased p53 signaling. The fndings herein showed that NAC could help alleviate hepatotoxicity, a serious therapeutic complication, by reducing CP-induced oxidative stress and playing an efective part in the regulation of apoptotic markers.eninfo:eu-repo/semantics/closedAccessCisplatinN-acetyl cysteineHepatotoxicityApoptosisOxidative StressArticle48163764410.1007/s11033-020-06111-0Q4WOS:0006074888000042-s2.0-8509943400233439409
