(A) Effect of lentivirally mediated stable expression of miR-3151 or a scramble control on TP53 mRNA abundance in KG1 and MV4-11 cells. Data were normalized to the scramble control value for each cell line (mean ± SD, n = 3 biological replicates; P values based on two-tailed Student’s t test). (B) Effect of lentivirally mediated stable expression of miR-3151, BAALC, or both (miR-3151/BAALC) on TP53 mRNA abundance in KG1 and MV4-11 cells. Data were normalized to the scramble control value for each cell line (mean ± SD, n = 3 biological replicates; P values based on two-tailed Student’s t test). (C) Western blot analysis of TP53 abundance comparing miR-3151–infected MV4-11 cells with scramble control. Left: representative blot; right: quantification of the changes relative to actin as determined by densitometry (mean ± SD, n = 3 blots; P values based on one-tailed Student’s t test).
