Fig. 1. Establishment of a xenograft model of breast cancer suffering mental stress.
A Schematic representation of the work flow to develop the model. B Increased levels of corticosterone (CORT) in the serum of the mice treated with mental stress. C, D Behavioral test of the mice by open field test (OFT). E Behavioral test of the mice by sucrose preference test (SPT). F Behavioral test of the mice by tail suspension test (TST). Ctrl: control; MS: mental stress. Data are presented as the mean ± SEM (n = 4 for Ctrl group, n = 5 for MS group). *p < 0.05, **p < 0.01.
