ABSTRACT
Abstract To explore the effect of fruit and vegetable (FV) juice on biomarkers of oxidative damage and antioxidant gene expression in rats, 36 adult male Wistar rats were randomly divided into control, low FV juice dosage or high FV juice dosage treatment groups. The rats were given freshly extracted FV juice or the same volume of saline water daily for five weeks. After intervention, serum and tissues specimens were collected for biomarker and gene expression measurement. FV juice intervention increased total antioxidant capacity, glutathione, vitamin C, β-carotene, total polyphenols, flavonoids levels andglutathione peroxidaseenzyme activity in rat serum or tissues (p < 0.05). FV juice intervention caused reduction of malondialdehyde levels in rat liver (p < 0.05) and significantly modulated transcript levels of glutamate cysteine ligase catalytic subunit (GCLC) and NAD(P)Hquinone oxidoreductase l (NQO1)in rat liver and brain (p < 0.05). The results underline the potential of FV juice to improve the antioxidant capacity and to prevent the oxidative damage in liver, brain and colon.
