NDRG2 and B-cell chronic lymphocytic leukemia: The results verified by qRT-PCR analysis of CLL cells treated with the two miRNAs inhibitors showed remarkable knocking down of miR-28-5p and miR-650 expression (Fig. 3a, c, P = 0.009 and P = 0.019, respectively) as well as upregulated NDRG2 at mRNA level after transfection of the two miRNAs inhibitors as compared with the cells transfected with miR-NC (Fig. 3b, d, P = 0.001 and P = 0.031, respectively).
