Abstract
The protective effects of Crocin (CRO), a carotenoid with wide spectrum of pharmacological effects, against the cytotoxicity and the apoptosis produced by exposure to Dichlorvos (DDVP) in HCT116 cells were investigated in this work. The cytotoxicity was monitored by cell viability, ROS generation, antioxidant enzymes activities, malondialdehyde (MDA) production and DNA fragmentation. The apoptosis was assessed through the measurement of the mitochondrial transmembrane potential (ΔΨm) and caspases activation. The results indicated that pretreatment of HCT116 cells with CRO, 2h prior to DDVP exposure, significantly increased the survival of cells, inhibited the ROS generation, modulated the activities of catalase (CAT) and superoxide dismutase (SOD) and reduced the MDA level. The reduction in mitochondrial membrane potential, DNA fragmentation and caspases activation were also inhibited by CRO. These findings suggest that CRO can protect HCT116 cells from DDVP-induced oxidative stress and apoptosis.
