Depression Induced by CUMS Leads to Bladder Cancer Development and Local Tumor Immunosuppression in Mice

Table 2

Weight of mice before and after experiments, weight of removed tumors, and tumor growth rate.

	Weight of mice (day 0)	Weight of mice (day 15)	Weight of tumors	Tumor growth rate (%)
Control group (g, mean ± SD, n = 10)	10.32 ± 0.63	19.31 ± 0.34	1.26 ± 0.37
CUMS group (g, mean ± SD, n = 10)	9.79 ± 0.38	20.16 ± 1.43	1.84 ± 0.46	46.03

CUMS promoted the bladder tumor growth significantly. There was no significant difference between the weights of mice in the two groups on day 0 or day 15. Weights of tumors from the CUMS group were significantly higher than those from the control group.
