Additionally, ELK1 was found to be positively correlated to Carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5 or simply CEA) expression and all three proteins (KIT, ELK1, CEA) were reported to be upregulated in CRC patients, highlighting the importance of the KIT/MAPK/ELK1/CEA axis as prognostic/diagnostic marker and as a potential pharmaceutical target [113]. This evidence concerns the gene CEACAM5 and colorectal carcinoma.
