GO-201 induces late apoptosis/necrosis of KU812 and K562 cells. KU812 (A and B) and K562 (C and D) cells were left untreated (Control), and treated with 5 µM GO-201 or CP-1 each day for 2 days. Cells were stained with propidium iodide (PI) and Annexin V, and analyzed by flow cytometry (A and C). The results are expressed as the percentage (mean ± SD of three determinations) of cells with late apoptosis/necrosis (B and D).
