Abstract Title:
Studies on Protection of Astaxanthin from Oxidative Damage Induced by H2O2 in RAW264.7 Cells Based on 1H NMR Metabolomics.
Abstract:
Astaxanthin (AST), a fat-soluble and non-vitamin A source of carotenoid which can quench reactive oxygen species and it has strong antioxidant, anti-inflammatory ability. Herein, we have used H2O2 to establish a model of oxidative damage to RAW 264.7 cells and cells treated with vitamin C as the positive control group. The changes in metabolome were examined using 1H NMR and the results demonstrated that H2O2 treatment, various metabolic pathways such as amino acid, glucose, and glycerolipid metabolism were downregulated which in turn affected citric acid cycle and energy status. AST could reverse downregulation of some of these metabolic pathways to a certain extent, and reduce cellular oxidative stress and death. The AST group differed from the vitamin C group in regulating D-glutamine, D-glutamic acid, pyruvate, and glycerolipid metabolism. The experimental results help to further understand the antioxidant effects of AST.
