(b) RT-PCRs show a significant increase in the expression of PU.1 mRNA in the OCI-M2 cells treated with DZNep in a dose-dependent manner. (c) Flow cytometric studies show that an increase in the expression of glycophorin A/B, a marker associated with erythroid differentiation, in the OCI-M2 cells treated with 0.25 μM of DZNep for 6 days. Red, isotype control; blue, no drug treatment (DMSO only); green, plus drug. (d) Increased PU.1 mRNA expression in primary MDS bone marrow cells treated with DZNep, compared with that in DMSO control.
