DICER1 and colorectal carcinoma: We first found the expression level and clinical significance of DICER1‐AS1 in CRC tumors and normal tissues by bioinformatics analysis, which showed that DICER1‐AS1 was expressed at low levels in normal colon tissues and significantly upregulated in CRC tissues; in addition, DICER1‐AS1 was strongly associated with disease progression and a poor prognosis.
