Fig. 2. GQD and anti-mouse PD-1 combination therapy inhibits tumour growth of colon carcinoma in vivo.

a Schema of sample collection and analysis. b Tumour volume changes in mice treated with GQD (300 mg/kg) + anti-mouse-PD-1, GQD (1500 mg/kg) + anti-mouse-PD-1, GQD (7500 mg/kg) + anti-mouse-PD-1, GQD (300 mg/kg), GQD (1500 mg/kg), GQD (7500 mg/kg), anti-mouse-PD-1 or normal saline (model) are shown. Data are presented as the mean ± SD. c Tumour growth inhibition rate (TGI) of mice. d Photographs of representative tumour blocks collected from mice from different treatment groups on 6 weeks + 32 days are shown
