PCYT2 and colorectal carcinoma: We also examined the expression of PCYT2 in CRC cell lines (Lovo, SW480, HCT116, SW620, COLO320, and HT29) and the normal colon cell line NCM460 and observed the highest expression in SW480 and SW620 cells compared with lower expression levels in HCT116 and HT29 cells (Figure 1F).
