This study evaluated the ameliorative potential of grape seed extract (GSE) against Ehrlich solid tumor (EST)-induced hepatic tissue alterations in mice. The control group was infused with physiological saline. The second group received GSE (50 mg/kg day by day orally) for 2 weeks. The third group was subcutaneously injected with 2.5 million of EST cells. The fourth group was injected with EST cells and treated with GSE extract simultaneously. The fifth group was injected with EST cells and kept for 2 weeks until the appearance of a solid tumor, then treated with GSE for 2 weeks. The phytochemical analysis of GSE revealed the presence of total phenols (17.442 mg GAE/g) and total flavonoid (6.687 mg CE/g) with antioxidant activity of 81.506 mg TE/g DPPH. The Ehrlich solid tumor significantly raised the activities of ALT, AST, and ALP; the level of alpha fetoprotein (AFP) in serum; and the protein expressions of hepatic proliferating cell nuclear antigen (PCNA) and tumor suppressor protein (P53), as well as induced DNA damage and pathological alterations in liver tissue. However, it significantly reduced serum albumin and total protein levels. In contrast, the co- or post-treatment of EST-bearing mice with GSE reduced the activities of ALT, AST, and ALP; the level AFP in serum; and hepatic P53 and PCNA protein expressions. In addition, it reduced EST-induced hepatic DNA damage and pathological alterations, while it increased serum albumin and total protein levels. This study suggested that GSE is a potent hepatoprotective agent and both co- and post-treatment of EST-bearing mice with GSE almost had the same effects.
