Inhibitory effects of PD on the growth of human lung cancer and non-cancer HBE cells. Exponentially growing cells in 96-well plates were continuously treated with the indicated concentrations of PD for 24 and 48 h and then subjected to MTT viability assay. Dose-response curves of PD in (A) A549 and (B) NCI-H1975 cells 24 or 48 h following treatment. (C) Viability of A549, NCI-H1975, and HBE cells 48 h following 2, 4, and 6 μM PD treatment. Data are presented as the percentage of DMSO-treated controls (mean ± SD) from three independent experiments. PD, polydatin; HBE, human bronchial epithelial; MTT, thiazolyl blue tetrazolium bromide; DMSO, dimethysulfoxide.
