Compared to normal tissue with an expression profile normalized to 1, in tumour samples 7 genes (ABCA8, AQP8, CLCA4, HPGD1, PRDX6, SLC26A3, and STX12) were uniformly under expressed in all 8 CRC patients, 3 genes (MXI1, NDRG2 and SCNN1B) in 7 patients, and 3 other genes (SGK2, NR3C2, and SGK1) in 6 patients. This evidence concerns the gene NDRG2 and neoplasm.
