In vivo tumor growths of HCT 116 and HCT 116/5-FU cells in mice models. a. The formation of tumors of HCT 116 and HCT 116/5-FU cells in mice models. b. The in vivo growth of HCT 116 and HCT 116/5-FU xenografts were monitored by 3-day measurements on tumor volumes (n = 6). c. After 21 days, the mice were sacrificed and the tumors were removed. Tumor samples were used to detect the expression of CCAT1 by qRT-PCR. *P < 0.05, **P < 0.01, compared with HCT 116 cells in mice model
