Given that we observed phosphopeptides associated with cellular processes relevant for CRC, we were next interested in taking a closer look at the phosphorylation patterns of proteins known to play a role in the proteins represented in the KEGG pathways “Colorectal Cancer” (hsa05210) or “PI3K-AKT pathway” (hsa04151) (Figure 6). This evidence concerns the gene PIK3CA and colorectal carcinoma.
