Markus Stoffel and colleagues reported that lncRNA could trigger miRNA degradation through interacting with it in ceRNA regulation.19 Another study reported that lncRNA CCAT2 could interact with miR‐145 to prevent its maturation in colon cancer cells.20 Here, the mechanism of FTX‐mediated miR‐200a‐3p decay is still unclear and needs further study. The gene discussed is CCAT2; the disease is malignant colon neoplasm.
