a RT-PCR relative expression of miR-567 normalized on U6 housekeeping gene, in MCF7 (in white) and MDA-MB-231 (in gray) cell line, respectively. All data are presented as mean ± SD of experiments for each bar (***t test p value = 4.5 × 10−5, n = 9). b RT-PCR relative expression of KPNA4 gene normalized on RPS14 housekeeping gene, in MCF7 (in white) and MDA-MB-231 (in gray) cell line respectively. All data are presented as mean ± SD of experiments for each bar (**t test p value = 0.0048, n = 9)
