Objectives: Antioxidant effects of Gagam-Jangwonhwan(LMK01 and 02) water extract against H2O2-induced oxidative damage and cell death were investigated in rat pheochromocytoma line PC 12.
Methods: The cells were treated with LMK01 and 02 water extract and H2O2, oxidative damage-inducing materials for 24 h. The cellular viability was assessed by WST-1 assay, oxidative damages of the cells by 8-OHdG quantitation, apoptosis by Hoechst 33342 staining assay and activity of antioxidant enzymes by catalase and glutathione peroxidase assay.
Results: 1. LMK01 and LMK02 water extracts improved significantly cell viability in H2O2-treated groups than H2O2-alone treated cells 2. LMK02 suppressed significantly oxidative damage in H2O2-treated groups than H2O2-alone treated cells but LMK01 didn’t. Meanwhile, difference of oxidative damages in conditions treated with LMK01 or LMK02 was not significant, 3. The H2O2 induced-apoptosis in PC 12 cell lines was inhibited effectively by LMK01 and LMK02, and especially the features of apoptosis were obviously reduced in LMK02-treated cells. 4. LMK01 and LMK02 increased significantly activities of both catalase and glutathione peroxidase than those of H2O2-alone treated group and moreover, LMK02 showed significantly higher activities than those of LMK01.
Conclusions: As shown, LMK01 and LMK02 suppressed H2O2-induced oxidative damage and cell death in PC 12 cell effectively. And they increased activity of major antioxidant enzymes in PC 12 cell line. Therefore, this study suggests the possibility of clinical usage over oxidative stress-induced neurodegenerative disease such as Alzheimer’s disease.
