Figure 4a depicts phosphorylation levels that are significantly induced in all the CRC cell lines as well as in HepG2 (human hepatoblastoma carcinoma cell line) cell line compared to that of the IEC-6 cells. Similarly, Figure 4c shows that CEA levels are also increased in all CRC cell lines and HepG2 cell line when compared to IEC-6 cells. Here, CEACAM5 is linked to colorectal carcinoma.
