Effect of miRNA overexpression on PLD protein expression and activity.
A–B, PLD2 protein expression in MCF-7 and MDA-MB-231 cells, respectively, in the presence of miR overexpression was detected by Western blot (W.B.). β-Actin was used as a control. C, PLD2 protein expression was decreased with increasing amounts of overexpressed microRNA-3619. β-Actin was used as a control. D, PLD enzymatic activity was measured in HMEC, MCF-7, and MDA-MB-231 cell lines in the presence of microRNA overexpression. Non-transfected cells were used as a control. The symbols * or # denote statistically significant (p < 0.05) increases or decreases, respectively, between samples and controls. E, effect of different combination of miRs on PLD enzymatic activity.
