SW480, a non-metastatic cell line, exhibited a low level of IFITM1 expression, whereas metastatic cancer cell lines such as HT29, HCT116, and SW620 exhibited a high level of IFITM1 expression (Figure 1A and 1B), suggesting that IFITM1 might be linked to metastasis and progression of colorectal cancer. This evidence concerns the gene IFITM1 and colorectal cancer.
