Abstract
The aim of this study is to investigate protective effects of sesaminol on the human bronchial epithelial (BEAS-2B) cell line against oxidative damage of cigarette smoke extract (CSE). BEAS-2B cells were pre-incubated with sesaminol for 12 h and then treated with various concentrations of CSE for 24 h. After that proliferation ability, levels of reactive oxygen species (ROS) and lactate dehydrogenase (LDH), cell apoptosis, activities of catalase (CAT) and superoxide dismutase (SOD), and mRNA levels of IL-8 and IL-6 were measured. The results showed that sesaminol significantly improved BEAS-2B cell viability, reduced the production of ROS and LDH of cells, inhibited cell apoptosis and increased CAT and SOD activities in CSE-treated cells. Sesaminol also inhibited the expression of IL-8 and IL-6 mRNA following CSE exposure. In conclusion, sesaminol may protect BEAS-2B cells against CSE-induced oxidative damage.
