Browsing the CancerMIRNome database34 (http://bioinfo.jialab-ucr.org/CancerMIRNome/; accessed on 25 June 2022), it was found that 4 of the 7 miRNAs enriched in the breast cancer pathway (hsa-miR-15b-5p, hsa-miR-20a-5p, hsa-miR-93-5p, hsa-miR-20b-5p), 5 of the 7 miRNAs enriched in the TGF-β signaling pathway (hsa-miR-17-5p, hsa-miR-20a-5p, hsa-miR-93-5p, hsa-miR-130a-3p, hsa-miR-20b-5p) and hsa-miR-103a-3p enriched in the AMP-activated protein kinase signaling pathway. This evidence concerns the gene TGFB1 and breast carcinoma.
