Expression of p27kip-1 in HL-60 cells as measured by Western blot. Cells were either untreated (lane 1) or treated with either Ro 25-9716 (10−7 mol/L, [A]) or 1,25D3 (10−7 mol/L, [B]) for 1 day (lane 2), 2 days (lane 3), 3 days (lane 4), 4 days (lane 5), or 5 days (lane 6). Lysates from the cells were analyzed for expression of p27kip-1 or MPO using Western blot analysis.
