For the third dataset GSE39582, the mean value (6.303) of CXCL8 in the normal cell (0,0) is significantly smaller than the mean values of CXCL8 in CRC cells (1,1), (1,3), (1,5), (1,6), (1,7); the mean value (9.507) of PSMC2 in (0,0) is smaller than the mean values of PSMC2 in cells (1,1) and (1,3-7); the mean value (10.19) of SLC20A1 in (0,0) is larger than the mean values in all other cells. Here, SLC20A1 is linked to colorectal carcinoma.
