Ameliorative role of naringenin against lead‐induced genetic damage and oxidative stress in cultured human lymphocytes

Zusammenfassung:Lead (Pb) is a ubiquitous toxic heavy metal that is known to induce damage to major macromolecules (lipids, proteins, and nucleic acids) by enhancing the level of reactive oxygen species (ROS). Naringenin, a predominant flavonoid primarily found in citrus fruits has attained increasing attention due to its various pharmacological properties. Thus, the present investigation aimed to explore the ameliorative role of naringenin against Pb‐induced toxicity in human peripheral blood lymphocytes (PBLs) under in vitro conditions. For this purpose, PBLs were exposed to Pb (350 µg/ml) alone as well in combination with naringenin (10 and 30 µg/ml). Sister chromatid exchange (SCE) and alkaline comet assay were used as genotoxic indices to evaluate the genotoxic and antigenotoxic activity of Pb and naringenin, respectively. Lipid peroxidation (LPO), glutathione peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD), and reduced glutathione (GSH) assays were used as oxidative damage markers. The results revealed that Pb induced a significant (p
