In BC, we identified expression of hsa-miR-497, hsa-miR-4324, hsa-let-7c, hsa-miR-199a-5p, and hsa-miR-195 to consistently and positively correlate with Pten-loss, whereas phsa-miR-13535, hsa-miR-106b, hsa-miR-18a, hsa-miR-18b, and hsa-miR-93 to negatively correlate with low PTEN expression (Additional file 1: Figure S1C; Additional file 2: Table S1C). This evidence concerns the gene PTEN and breast cancer.
