In addition, increasing evidence have demonstrated that IFITM1 was also upregulated in numerous tumor tissues as well as cancer cell lines, such as colorectal cancer (5), gastroesophageal adenocarcinoma (6), gastric cancer (7, 8), hepatocellular carcinoma (9), lung cancer (10), breast cancer (11, 12), head and neck cancer (13, 14), gallbladder carcinoma (15), ovarian cancer (16), glioma (17), and nasopharyngeal carcinoma (18). Here, IFITM1 is linked to cancer.
