Curcumin Attenuates Aroclor 1254‐Induced Oxidative, Genotoxic, and Apoptotic Alterations in HepG2 Cells

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
In HepG2 cells, Aroclor 1254 induced oxidative stress, DNA damage, apoptosis, and mutagenicity; co‐treatment with curcumin restored antioxidant defenses (GSH/thiols; SOD, CAT, GPx, GR, TrxR), reduced ROS and comet/8‐OHdG readouts, and attenuated caspase activation, demonstrating curcumin's hepatoprotective and genoprotective modulation of PCB toxicity.
