For the self-collected dataset, the mean value (0.3774) of CXCL8 in the normal cell (0,0) is significantly smaller than the mean value (0.8049) of CXCL8 in CRC cells (1,2), but 30-80 times smaller than those (11.43, 24.78) in (1,3) and (1,6); the mean value (0.9826) of PSMC2 in (0,0) is smaller than the mean values of PSMC2 in cell (1,2), (1,3), (1,6); the mean value (1.956) of SLC20A1 in (0,0) is larger than the mean value in all other cells. The gene discussed is PSMC2; the disease is colorectal carcinoma.
