Background: Failure of endogenous antioxidant system to eliminate high levels of ROS results to oxidative stress, consequently leading to liver damage. Excessive alcohol consumption leads to liver damage due to ROS generation, thus regarded as the leading causes of death worldwide, suggesting great need for use of exogenous antioxidants like epigallocatechin-3-gallate (EGCG), to avert liver damage. However, underlying EGCG mechanisms remains elusive.Aim of the work: This study focused on mechanistic role of EGCG in regulation of antioxidant marker activities during ethanol induced liver damage.Materials and Methods: 20 male Swiss Albino mice were divided into four groups and treated with different dosage. ALT, AST and total proteins were determined as indicators of liver damage. MDA and protein carbonyls were measured as oxidative stress markers. Activities of SOD and CAT were determined. SOD-2 and CAT differential gene expression were also determined. Liver histology analysis by H&amp;E staining. All the experiments were run in duplicates. ANOVA was used to analyzes data using Tukey’s multiple comparison tests and results considered statistically significant if p ≤ 0.05 at 95% confidence level. Results: Findings revealed that chronic consumption of ethanol leads to liver damage through increased levels of serum ALT and AST, MDA, protein carbonyls and remarkable diffuse lipid droplets and decreased enzyme activity of SOD and CAT. EGCG increased activity of SOD and CAT and SOD-2 expression and did not affect CAT expression. Conclusion: In summary, ethanol induces liver damage, and administration of EGCG increases antioxidant system expression, suggesting its role in regulating their activities, defensive of oxidative stress through various pathways.
