Abstract

Two self-made aged garlic extract (AGE) were prepared and they were subjected with D-galactose-induced mice to explore vivo antioxidant effects and its mechanism via gene chip analysis. The biochemical analysis results indicated that AGE could significantly reduce the malondialdehyde (MDA) and lipofuscin content and increase the total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), catalase (CAT) activity. Histopathological observations found that AGE could improve the size, shape and arrangement state of liver and brain cells. Furthermore, gene expression profile array was used to screen 35 and 13 differentially expressed genes in liver and brain, respectively. Further analysis showed that the AGE could protect the mice from D-galactose-caused injury via carbohydrate metabolism, immunomodulatory, lipid metabolism, cell cycle regulation, amino acid metabolism and nervous regulation pathways. Through this experiment, we could comprehensively study the antioxidant mechanism of AGE and link the antioxidant function of AGE to the metabolic pathways.
