Tumors with lower IFNG SHAP values exhibited higher IFNG expression and better overall survival, which were linked to more abundant presence of M1 macrophages and activated CD4+ and CD8+ T cells in the tumor microenvironment. The association of the IFNG pathway with overall survival was validated in the trastuzumab arm of the NCCTG-N9831 trial, an independent breast cancer study.

Linrodostat + nivolumab ± ipilimumab demonstrated a manageable safety profile. Kynurenine changes supported IDO1 pathway inhibition but did not correlate with response. A composite biomarker of low TDO2 expression plus high IFN-γ gene expression may predict response to linrodostat + nivolumab.

Oxymatrine reversed IFN-γ-induced upregulation of PD-L1 expression; moreover, it downregulated xCT and GPX4 protein levels in liver cancer cells and promoted intracellular Fe2+, ROS, and MDA levels.

Treatment with the KRasG12C-specific inhibitor, ARS-1620, significantly increased IDO1 expression, which inversely correlated with PD-L1 expression in the KRasG12C-mutant H358 cell line...Moreover, the induction of IDO1 expression following KRas inhibition appears to operate independently of the MAPK pathway. Our results propose that concurrent targeting of KRas and IDO1 could potentiate therapeutic efficacy in KRas-mutant cancers, overcoming resistance to immune checkpoint blockade.

ECH upregulates the expression of inducible PD-L1 through the JAK/STAT1/IRF1 signaling pathway, enhances T cell function, and reshapes the tumor immune landscape into an anti-tumor phenotype. Importantly, ECH markedly enhances the efficacy of ICB treatment, indicating its potential application in anti-tumor therapy.

Patients were randomized 1:1 to receive either Standard of Care (SoC) or SoC plus the MUC1-based antitumor vaccine tecemotide... The results of this study indicate that in the ABCSG 34 trial, PD-L1 positivity as determined by IC and CPS was able to predict better DRFS and OS. However, in patients with residual tumor, an increase in CPS during treatment was associated with decreased OS - a result that needs to be interpreted with caution, since no "post treatment sample" can be accessed in cases of pCR. In addition, IRF1 expression both in tumor cells and TILs predicted an improved IDFS and DRFS.
