The Inhibitory Effect of Phytochemicals on the Oxidative DNA Damage in Lymphocytes by Chrysotile

초록

We investigated the cytotoxicity and oxidative DNA damage by chrysotile, one of the asbestos, in this investigation. Chrysotile enhanced malondialdehyde (MDA) levels and intracellular reactive oxygen speices generation in human airway epithelial cells. Furthermore, asbestos-induced oxidative DNA damage in lymphocytes was evaluated by single cell gel electrophoresis and quantified as DNA tail moment. Notably, phytochemicals such as curcumin, berberine, and sulforaphane presented inhibitory effect on the asbestos-induced oxidative DNA damage in lymphocytes.
