| Background Previous investigations showed that jojoba oil exhibited a protective effect against hepatotoxicity caused by different toxicants, however, to the best of our knowledge, no prior research has been done to determine the effectiveness of jojoba oil in protecting against lead toxicity. Objective This study assessed the hepatoprotective properties of jojoba oil against lead toxicity in rats. Materials and methods The study included four groups, each consisting of six Sprague Dawley male rats, and orally administered jojoba oil (JO group), lead acetate (LA group), and lead acetate plus jojoba oil (protective group) Results and conclusion The results showed that lead acetate-induced hepatotoxic effects were revealed by increased serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities with hepatic histomorphological changes. There was a significant increase in serum total cholesterol, triglycerides, and low-density lipoprotein-cholesterol, while levels of high-density lipoprotein-cholesterol significantly declined compared to normal rats. Additionally, lead acetate triggered oxidative damage of hepatocytes, evidenced by a significant increase of malondialdehyde levels and a decrease of reduced glutathione levels and activities of superoxide dismutase and glutathione S-transferase. Administration of lead was associated with a change in the distribution of cells over different cell cycle phases, characterized by a marked increase in the sub G1 cell population and a significant decrease in the G0/G1 cell population. Supplementation of jojoba oil with lead acetate relieved the toxic impacts of lead acetate with an enhancement of the liver enzyme activities, antioxidant status, lipid profile parameters, and histopathological alterations. In conclusion, jojoba oil might be an effective natural product that offers a promising preventive action towards lead-induced liver damage in rats. | ||||
