Previous big data from microarray assays have found that circTCF25 overexpression promoted CDK6 expression by sponging miR‐103a‐3p and miR‐107, which eventually promoted BC cell migration and proliferation.14 In current research, the results of microarray assays illustrated that circVANGL1 (hsa_circ_0002623) was also expressed aberrantly. The gene discussed is CDK6; the disease is breast cancer.
