IFITM1 and colorectal cancer: The proliferation rate of IFITM1-depleted SW620 and HT29 was decreased by about 10∼35% of control cells, suggesting that the proliferation was modestly impaired in the absence of IFITM1 in colorectal cancer cell lines including SW620 and HT29, but not in HCT116 (Figure 2C–2E).
