For instance, it was reported that upregulated hsa_circ_0006528 contributed adriamycin-resistant in breast cancer via the miR-1236-3p/CHD4 axis and circABCB10 was overexpressed in breast cancer that was involved in paclitaxel resistance through the circRNA/let-7a-5p/DUSP7 axis [34, 35]. The gene discussed is DUSP7; the disease is breast carcinoma.
