SGK2 and malignant colon neoplasm: Second, we selected 10 of 21 genes (ABCA8, AQP8, HPGD, PRDX6, SLC26A3, STX12, NDRG2, MXI1, SGK2, and SCNNB1) as possible targets of epigenetic modifications in colon cancer, and after treatment with a demethylating agent, seven of them showed a significant increase of mRNA expression (AQP8, HPGD, PRDX6, MXI1, SCNNB1, SGK2 and NDRG2).
