Background:   Liver injury due to ionizing radiation exposure either accidental or after radiotherapy treatment, may lead to many alterations in proteins expression related to inflammation or apoptosis. Our study investigated the curative effect of Mangosteen (MGS) extract (fruit rind) against ionizing radiation (IR) induced liver damage.Methods:   Hepatotoxicity was induced in Wister rats by exposure to an acute single dose (6 Gy) of IR while MGS was given orally to rats (500 mg/kg bwt) and administered daily for 30 days after irradiation.Results:   MGS treatment has significantly attenuated redox imbalance state and toxicity induced by protracted exposure to gamma-rays in liver tissues, which was substantiated by the significant amelioration of liver function tests, MDA contents, antioxidant enzymes (SOD and CAT) activities and NO level. MGS inhibited also the inflammatory markers (TNF-alpha, IL-6 and CRP) and downregulated transcriptional factor NF-Kappa-B/TGF-β1. These alterations were concomitant with an improvement of the Proliferating cell nuclear antigen (PCNA) which is a protein expressed in the nuclei of cells during cell cycle and is important for both DNA synthesis and DNA repair. These results were confirmed by amelioration in histological and ultrastructural examinations.Conclusion:   We concluded that MGS could ameliorate via minimizing significantly the amount of oxidative damage, inflammations disturbances and pro-apoptotic alternations induced by IR. MGS may be a promising supplement with protective effects from irradiation-induced injury such as TNF-α/NF-κB/TGF-β1 management.
