The CLK2 expression in colorectal cancer tissue and adjacent normal tissue. (a) The CLK2 expression in 48 normal colorectal samples and 554 colorectal cancer samples in TCGA cohort. (b) The CLK2 expression in 48 paired colorectal normal and cancer samples in TCGA cohort. (c) The CLK2 expression in 50 paired colorectal normal and cancer samples in our validation cohort. (d)–(g) The Human Protein Atlas database shows the immunohistochemical results of CLK2 in CRC tissue compared with noncancerous colon tissues.
