As a result, we noticed differences in changes of tumor weight/volume that were greater between anti-PD-1-antibody-treated than isotype control-treated mice (p=0.07), suggesting that anti-PD-1 antibodies are more effective in KPCY55 tumors of GPR55 KO than WT mice (Supplementary Figure S8C). This evidence concerns the gene GPR55 and neoplasm.
