To further explore the role of MTERF1 in CRC and the mechanisms of its oncogenic function, we first analyzed the relative expression level of MTERF1 protein in a normal human colorectal cell line (FHC) and CRC cancerous cell lines (HT29, HCT8, SW480, Caco2, HCT116, and RKO). This evidence concerns the gene MTERF1 and colorectal carcinoma.
