Many miRNAs have been shown to be aberrantly expressed in CRC by miRNA-CHIP assays, and the functions of some miRNAs have already been clarified.12 Examination of the colorectal miRNAome revealed that miR-612 was downregulated in tumors versus non-tumor colorectal tissues, but its role in CRC occurrence remains unknown. The gene discussed is STUB1; the disease is colorectal carcinoma.
