circFBXL5 acts as a ceRNA to regulate SRSF6 (A). The predicted binding sites of miR‐660 within the SRSF6 3′UTR. B, The expression of SRSF6 in breast cancer cell lines. C, Cells were transfected and luciferase assay was performed. D, Cells were transfected, and the expression of SRSF6 was detected. E, The expression of SRSF6 was detected. F, RIP assay showing the enrichment of circFBXL5, SRSF6 and miR‐660 on Ago2 relative to IgG. G, Cells were transfected and RIP assay on Ago2 was performed. H, Cells were transfected, and the expression of SRSF6 was detected. **P < .01
