Abstract: (295 Views)
Introduction: Impact of antioxidant supplements on the health of patients with Alzheimer’s disease has not yet been clearly defined. Given that no study has been conducted so far to evaluate the effectiveness of vitamins C and E on the expression of Carbonyl Protein (CP) and Heat Shock 70 (HSP70) genes in rats with Alzheimer’s, this study aims to investigate the effect of an eight-week supplementation of vitamins C and E on the expression of CP and HSP70 in the brain tissue of rats with Alzheimer’s disease.
Methods: In this experimental study, 28 rats with Alzheimer disease were injected with 10 mg/kg of trimethyltin and divided into four groups: patient control, sham (soluble vitamin E), Vitamin C, and Vitamin E (VE). Seven healthy rats were included in the control group to investigate the effects of disease induction on the variables under study. They were administered a daily supplement of 4 mg/kg of vitamin C and 30 mg/kg of vitamin E for eight weeks. After supplementation period, the groups were compared in terms of CP values and HSP70 gene expression. Data were analyzed by SPSS16 statistical software. Shapiro-Wilk test was used to check normality of the finding distributions. Effect of vitamin E and vitamin C supplementation was evaluated using one-way analysis of variance. Tukey's post hoc test was used to check the type of variable effects. A significant level of 0.05 was considered for all analyses.
Results: Levels of carbonyl protein in both the vitamin C and vitamin E groups were significantly lower than those in the patient control group (P < 0.05). HSP70 levels in the vitamin C and E groups were significantly higher than those in the patient control group (P < 0.05). No significant difference was observed between vitamin C and E supplement groups (P > 0.05).
Conclusion: Findings of this study suggest that both vitamin C and E exhibit similar antioxidant and cellular protective effects in the brain tissue of mice with Alzheimer’s disease. Given the impact of vitamins C and E on reducing carbonyl protein levels and increasing HSP70 levels in the hippocampal tissue of rats, it is recommended to explore the effects of these vitamins on other neurodegenerative disorders in future studies.
