ABCB10 and breast cancer: Furthermore, the overexpression of circ-ABCB10 can stimulate tumor proliferation and invasion by sponging miR-1271, which is also a pivotal miRNA in most regulation processes of circRNAs in breast cancer (Wang et al., 2018) and promote the proliferation and progression of clear cell renal cell carcinoma by activating the target gene—miR-331-3p/miR-1228-5p (Huang et al., 2019).
