Suppression of cell growth by PI polyamide treatment (56-1 or 56-2) in primary AML cells. (a–d) Two primary AML cell samples with high expression of EVI1 and GPR56 (a,b) and two AML cell samples with low expression of EVI1 and GPR56 (c,d) were not treated (P) or treated with 1 μM PIP/AP2 (AP2), PIP/56-1 (56-1), or PIP/56-2 (56-2) or solvent only (C) and analyzed for cell growth by Trypan blue exclusion. Data represent the mean ± S.D. of triplicate determinations. **P < 0.01 between parental control and others (Student’s t-test). Data are representative of three independent experiments. (e) Colony formation assays were performed on human CD34+ progenitor cells not treated or treated with various PIPs (AP2, 56-1, or 56-2) or DMSO only (C). Data represent the mean ± S.D. of triplicate determinations. Data are representative of three independent experiments.
