Doxorubicin (DOX) is a widely used chemotherapeutic agent for various tumors treatment; apart from its activity, the traditional usage of DOX has been limited by adverse effects on multiple organs, mainly hepatotoxicity. The molecular mechanisms underlying hepatotoxicity are due to production reactive oxygen species (ROS) inducing oxidative stress, diminishing antioxidant enzymes, apoptosis, inflammation, and mitochondrial dysfunction. Thus, there an urgent need develop therapy that minimizes widens use in types cancers without fear serious Ginkgetin (GINK), natural biflavonoid, exhibits diverse actions, including promising free radical scavenging, antioxidant, anti-inflammatory activities. So, this study's objectives were determine whether GINK could mitigate DOX's hepatotoxic look into putative hepatoprotective pathway. Mice divided five groups: Normal control, control 100, Untreated group, groups treated with (50 100 mg/kg) intraperitoneally daily four days before administration additional three afterward. pretreatment showed marked protection also attenuation histopathological structural alterations.
