Abstract:Purpose: To investigate the influence of metformin on apoptosis of pulmonary carcinoma cells (A549), and the associated mode of action.Methods: Pulmonary carcinoma cells in logarithmic growth phase were treated with graded concentrations of metformin, and the anti-proliferative and apoptotic effects of the drug were measured using MTT assay and flow cytometry, respectively. The levels of reactive oxygen species (ROS) in A549 cell suspension were determined with 2, 7- dihydrodichlorofluorescein diacetate (DCFH-… Show more
