In vitro genotoxicity of mycotoxins ochratoxin A and fumonisin B1 could be prevented by sodium copper chlorophyllin – Implication to their genotoxic mechanism
The aim of this study was to investigate the possible protective effect of sodium copper chlorophyllin (CHL) against cytotoxicity and DNA damage induced by mycotoxins ochratoxin A (OTA) and fumonisin B1 (FB1). CHL (0.1–100 μg/ml) alone had no impact on cell viability and genome damage in the primary human peripheral blood lymphocytes (HPBLs) and exhibited free radical scavenging activity in the DPPH assay. Both mycotoxins, OTA (4 μmol/l) and FB1 (20 μg/ml), induced DNA damage in HPBLs already after 1 h exposure. When the HPBLs were co-exposed to CHL (10 and 100 μg/ml) and OTA (4 μmol/l) or FB1 (20 μg/ml) for 1 h, CHL protected against cell and DNA damage induced by both mycotoxins, implying that OTA and FB1 cytogenotoxicity mechanisms function at least partially through oxidative stress. Therefore, CHL could be a perfect candidate for possible use as an antioxidant.
