MYCBP and neoplasm: The facts that (a) MFI2‐AS1 sponged miR‐574‐5p and miR‐574‐5p were targeted to MYCBP; (b) miR‐574‐5p mimics inhibited proliferation, migration and invasion of CRC cells; and (c) miR‐574‐5p inhibitor retrieved the MFI2‐AS1 siRNA‐induced changes in CRC cells suggested the tumour suppressor role of miR‐574‐5p expression in CRC.
