Gene expression assessment in tumor samples collected from a MCA205 tumor-bearing model treated or not with anti-PDL1. Tumor samples were retrieved 13 days post tumor inoculation, and subjected to RT-qPCR for expression analysis of genes encoding for the different enzymes of the KP and key inflammatory cytokines. On the right bottom, display of the p-values vs. the log transformed ratio of tumor mRNA level between PDL1 and Vehicle. Means ± SEM are represented. Ido1, Indoleamine 2,3 dioxygenase 1; Ido2, Indoleamine 2,3 dioxygenase 2; Tdo2, Tryptophan dioxygenase; Kynu, Kynureninase; Kyat1; Kynurenine Aminotransferase 1; Got2, Kynurenine Aminotransferase 4; Haao, Hydroxyananthranilate oxygenase; Kmo, Kynurenine Monooxygenase.
