In our previous expression profiling analysis, miR-140-3p, miR-382-5p and miR-579-3p were predicted to be sponged by circZNF800 to collectively affect expression of the ALK7/ACR1C (activin A receptor type 1C), FDZ3 (frizzled class receptor 3) and WNT5A (WNT family member 5A) genes in spheroids derived from CRC cell lines [19]. Here, ACVR1C is linked to colorectal carcinoma.
