Cancer cell proliferation was measured by 3-(4, 5‐dimethylthiazolyl)2, 5‐diphenyl‐tetrazolium bromide (MTT) assay and apoptosis induction was analyzed by fluorescence microscopy (acridin orange/ethidium bromide, annexin V/propidium iodide staining, TUNEL assay and Caspase-3 activity assay). The gene discussed is CASP3; the disease is cancer.
