Abstract
Results showed that genistein restrained reactive oxygen species (ROS) and malondialdehyde (MDA) production, and ameliorated the inhibitory effect on superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and glutathione peroxidase (GPx) activity elicited by ox-LDL stimulation. The effects of genistein were correlated with the upregulation of sirtuin-1 via inhibiting miR-34a, and were abolished by sirtuin-1 siRNA or miR-34a mimic. Moreover, the antioxidation of genistein was associated with miR-34a/sirtuin-1-mediated nuclear translocation and deacetylation of foxo3a, accompanying with the enhanced expressions of MnSOD and CAT. The present study suggests that miR-34a/sirtuin-1/foxo3a might play an important role in genistein reversing ox-LDL-induced oxidative damage in HUVECs.
