Inhibitory effects of oxymatrine on NSCLC cells. (A) Oxymatrine inhibits anchorage‐dependent cell growth in a panel of human NSCLC cells, including A549 (left), H1975 (middle), and HCC827 (right). Cell viability was measured by MTS assay. (B) Three NSCLC cell lines, including A549 (upper), H1975 (middle), and HCC827 (bottom) were subjected to the soft agar assay. The average colony number was calculated from three separate experiments. Asterisk, significant (*P < 0.05, **P < 0.01, ***P < 0.001) suppression of cell viability or colony formation by oxymatrine compared with the DMSO‐treated group.
