ATG5 and breast cancer: To evaluate whether hsa-miR-30a serves as a novel autophagy inhibitor in BC cells, we evaluated several miRNA target prediction programs (i.e., TargetScan, miRDB, and miRNA.org) and confirmed that hsa-miR-30a-3p and -5p may directly target the 3′-UTR regions of ATG5/12 and Beclin 1.
