For instance, circ‐UBE2D2 accelerates breast cancer progression via adsorbing miR‐1236 and miR‐1287 (Wang, Li, et al., 2019); circ_0001730 acts as a miR‐326 sponge to upregulate Wnt7B to enhance glioma cell proliferation and metastasis (Lu, Deng, et al., 2019). This evidence concerns the gene WNT7B and breast carcinoma.
