Effects of deoxynivalenol, 3-acetyl-deoxynivalenol and 15-acetyl-deoxynivalenol on parameters associated with oxidative stress in HepG2 cells

This work studied the effect of deoxynivalenol (DON) and two of its acetylated analogs (3-ADON, 15-ADON) on first indicators of oxidative stress status, namely production of reactive oxygen species (ROS) and induction of lipid peroxidation (LPO), in HepG2 cells. HepG2 cells were exposed to different...

Description
Summary:This work studied the effect of deoxynivalenol (DON) and two of its acetylated analogs (3-ADON, 15-ADON) on first indicators of oxidative stress status, namely production of reactive oxygen species (ROS) and induction of lipid peroxidation (LPO), in HepG2 cells. HepG2 cells were exposed to different concentrations of the three toxins, either alone or in combinations, for 24, 48, and 72 h. Results of cytotoxicity obtained in HepG2 cells were correlated with the detection of ROS and LPO. This effect was inversely correlated with ROS while directly correlated with LPO for the assayed mycotoxins in individual treatment. Combinations of two toxins containing 15-ADON yielded highest values, while for two-toxin combinations with 3-ADON, the effects were minor. A combination of all three mycotoxins alleviated ROS production and the highest levels in LPO were detected, in association to a final breakdown of adaption of ROS early produced by HepG2. In conclusion, parameters of stress evaluation presented in this study (ROS and LPO), revealed increases in HepG2 cells exposed to DON, 3-ADON, and 15-ADON either individually or combined.
