For the fourth dataset GSE9348, the mean value (64.33) of CXCL8 in the normal cell (0,0) is significantly smaller than the mean value (39.47) of CXCL8 in CRC cells (1,1); the mean value (458) of PSMC2 in (0,0) is smaller than the mean value (509.6) of PSMC2 in cell (1,1); the mean value (4577) of SLC20A1 in (0,0) is twice larger than the mean value (1969) in cell (1,1). This evidence concerns the gene SLC20A1 and colorectal carcinoma.
