Antiproliferative and proapoptotic activity of CKIP-1 in glioma cells. (a) Cell cycle distributions were detected followed by propidium iodide (PI) staining in U251 cells transfected with CKIP-1 for 72 h by flow cytometry. (b) Cell cycle assays of percentage of cells in G0/G1 and S phases were quantified. (c) Annexin V-FITC/PI staining was analyzed from cells mentioned above. Lower right quadrant represents Annexin V+/PI- cells (early apoptotic cells). Upper right quadrant shows Annexin V+/PI+ cells (late apoptotic cells). (d) Apoptosis assay of percentages of apoptotic (early and late apoptotic) cells was quantified.
