As compared with noncancerous samples with low MALAT1 and TOP2A levels, BC cases with high MALAT1 and TOP2A levels showed low miR-561 levels, with Pearson correlation analyses revealing a clear inverse relation between miR-561 expression and MALAT1 and TOP2A mRNA levels (r = 0.4001; P value = 0.0233; r = 0.5310; P value = 0.0018, respectively; Fig. 3C, D). Here, TOP2A is linked to breast cancer.
