Fig. 2: PZH inhibited the growth of colorectal tumors and inhibited cancer liver metastasis.

A The image of the tumor. B Tumor volume with PZH treatment. Data represent the mean ± standard error of the mean (SEM) of experiments conducted on 6 mice. ns, no significance; *P < 0.05. C Tumor weight with PZH treatment. Data represent the mean ± SEM of experiments conducted on six mice. *P < 0.05. D The curve demonstrating the changes in mouse body weight. Data represent the mean ± SEM of experiments conducted on six mice. ns, no significance. E–G The tumor fluorescence signal intensity in the orthotopic tumor model with PZH treatment. Data represent the mean ± SEM of experiments conducted on 5 mice. *, **P < 0.05. H, I PZH inhibited the liver metastasis of orthotopic transplantation tumors, in comparison with the control group.
