Next, the correlations between the expression levels of DPY30 and PCNA, Ki67 and cyclin A2 in CRC were further analyzed by GEPIA 2 database (http://gepia2.cancer-pku.cn/, COAD and READ in TCGA expression data) (Fig. 5C), which showed that the expression of DPY30 was positively correlated with PCNA, Ki67 and cyclinA2. This evidence concerns the gene MKI67 and colorectal carcinoma.
