Fig. 5: Chronic restraint stress protocol.
From: Chronic stress promotes gastric cancer progression and metastasis: an essential role for ADRB2
a Seven days before the MGC803 cells were injected into the flanks of nude mice, the mice were exposed to chronic stress conditions (daily restraint) vs home cage control conditions for 8 h daily, lasting for 28 days. b Representative tumour images from the chronic stress group and the stress-free control group are displayed. c, d After 4 weeks, the adrenal gland diameters of the control group and the stress group were measured. e The weight curve of the two groups of nude mice is shown. f The mean tumour weight was monitored. g The volume of the tumour during the process of tumour growth at six different time points was determined. h Adrenal gland diameter quantitative results are shown. i, j The average levels of NA and Adr were analysed by ELISA
