They also pointed out that BC progression was dependent on the autophagy‐related protein Beclin‐1.56 Hu et al determined that the contributions of dual therapeutic targeting of miR‐124‐3p and ATP‐binding cassette subfamily C member 4 (ABCC4) in BC cells (MCF‐7‐ADR) may enhance drug sensitivity for Adriamycin‐resistant BCs. This evidence concerns the gene BECN1 and breast cancer.
