CircRNA_0044556 was negatively correlated with miR_145 yet positively correlated with NRAS, the target gene of miR_145, in addition to the discovery suggesting the negative regulatory effects of circRNA_0044556 on miR_145. CircRNA_0044556 diminished the sensitivity of TNBC cells to ADM via the miR_145/NRAS axis.
CircRNA_0044556 diminishes the sensitivity of triple_negative breast cancer cells to adriamycin by sponging miR_145 and regulating NRAS.
