Among human CRC cells, only HT29 cells exhibited increased Tyr and Ser phosphorylation upon CEACAM1 knockdown (Supplementary Figure 3C) that mirrors reductions in EPHA2 pTyr and pSer upon CEACAM1-L over-expression in MC38 cells (Figure 2C). This evidence concerns the gene CEACAM1 and colorectal carcinoma.
