Through the ncRNA network of colorectal cancer, we can clearly observe that the entire network graph is mainly divided into three large sub-networks (Including the miR-34a/b/c/miR-194-5p/miR21 sub-network, the CRNDE/EZH2/miR214/UCA1 sub-network and the miR-149/150-5p/LINC00460/miR-19a/20a sub-network) and a series of small networks (Including small networks with LNC00152, YAP, miR-27a, miR-24, miR-31, miR-7 as the core genes). Here, EZH2 is linked to colorectal cancer.
