In order to correlate the binding of RKOpep to the CRC cell lines with the expression of MCT1, its level of expression in the various cell lines under study, including RKO, Caco-2, HCT 116, HCT-15 and CCD-841-CoN, was evaluated through western blot (Fig. 6). This evidence concerns the gene SLC16A1 and colorectal carcinoma.
