Effects of ZA treatment on apoptosis detected by annexin V/PI ataining. a The MDA-MB-231 cells were treated without or with various concentration of ZA for 48 h. Annexin V-FITC/PI staining was carried out and determined using flow cytometry. b The distribution of MDA-MB-231 cells undergoing early (annexin V+ PI-) and late apoptosis (annexin V+ PI+) were qualified, after treatment with ZA
