The primary limitation of gentamicin (Gm) treatment is its potential to induce nephrotoxicity, which can restrict both its duration and efficacy. This study aims to investigate the protective effects of Crocin (Cr) against Gminduced nephrotoxicity and its underlying mechanisms, including inflammation, apoptosis, TLR-4, Nrf-2/HO-1 pathways. 36 Sprague Dawley rats were divided into 6 groups for the study. Group I received only saline. Groups II and III were administered 25 and 50 mg/kg of crocin, respectively. Group IV was treated with 80 mg/kg of Gm. Groups V and VI received 25 and 50 mg/kg of crocin, respectively, in addition to Gm administration. Crocin demonstrated protective effects on kidney tissue. It down -regulated the genes NF-kappa B, COX -2, TLR-4, Bax, and Caspase-3, while up -regulating Bcl-2, Nrf-2, and HO -1. In conclusion, these findings hold promise for the prevention of Gm -induced nephrotoxicity through the modulation of the Nrf-2/HO-1 pathway.
