ALFY is upregulated during ATRA-induced differentiation of AML cells. (a–c) NB4, NB4-R2 and HT93 APL cells as well as the non-APL HL60 cell line and its ATRA-resistant clone HL60-R2 were treated with 1 µM ATRA for 4 and 6 days. ALFY mRNA levels were determined by qPCR. Raw Ct values were normalized to HMBS and to the untreated control of day 4. Standard deviations are shown for at least three independent experiments. (d–e) NB4 cells were transduced with two shRNAs (#1 and #2) targeting different regions of the PU.1 or CEBPA mRNA or a non-targeting control (CTRL). After treatment with 1 µM of ATRA for 4 days ALFY mRNA levels were determined by qPCR and normalized as described in A.
