In another study, Jamai D et al. examined Excision Repair 1, Endonuclease Non-Catalytic Subunit (ERCC1) and O6-methylguanine-DNA-methyltransferase (MGMT) methylation as a possible marker for predicting response to FOLFOX chemotherapy in CRC patients (n = 111). Here, MGMT is linked to colorectal carcinoma.
