PRR11 and colorectal carcinoma: We explored the expression patterns of these six genes in the CRC training set (TCGA-COADREAD), CRC validation set (GSE87211), AS training set (GSE100927), and AS validation set (GSE43292) (Figures 5A-D); the results showed that PRR11 exhibited expression levels of 0.89 and 0.96 in the CRC training set and validation set, respectively, and 0.936 and 0.794 in the AS training set and validation set, respectively.
