Protective Effects of Coadministration of the Vitamin E and Omega-3 on Doxorubicin-Induced Hepatotoxicity in Mice

Background: Doxorubicin is a favorite drug for feasting many malignancies. All organs' hepatic toxic effects are destructive and lead to use with caution. Then, it is necessary to increase antioxidants accompanied with doxorubicin to reduce its toxicity. Vitamin E is an antioxidant with harmful consequences. Omega-3 is an antioxidant similarly. The healing capacity of Vitamin E- Omega-3 was investigated together against doxorubicin. Methods: Thirty balb/c mice have divided a weight of 25 g into five equal groups of six mice each. The groups were classified as Control: normal saline; DOX: Doxorubicin; Vitamin E: Vitamin E + DOX; Omega-3; Omega-3 + DOX; Both Vitamin E- Omega-3 + DOX. The histopathology was set to describe vacuolar degeneration, inflammation, and necrosis. Immunohistochemistry was performed to estimate the expression of tumor necrosis factor (TNFα), demonstrating the inflammation. Results: DOX-induced hepatic injury and increased TNF-α expression were seen more than alone when co-administered with vitamin E and omega-3. A significant decrease was shown in the ALT, AST, GGT, and ALP levels compared to the control. The Glutathione peroxidase and Catalase enzyme activities were higher in the co-administered Vitamin E- Omega-3 group than that received Vit E or Omega-3. Conclusions: Co-administration of Vitamin E and Omega-3 have a more repair capacity with controlling effects on Doxorubicin-induced liver toxicity.
