Asiatic acid induces apoptotic cell death and cell cycle arrest in lung cancer cells. (A) A549 cells were treated with asiatic acid (20, 40 and 80 μmol/L) for 24 h, stained with DAPI and nuclei photographed. (B) A549 cells treated with asiatic acid were collected and subjected to annexin V/PI analysis (B). Data represent mean±SEM of three different experiments.
