The expression of NLRC5 and NLRC5-dependent MHC class I and CD8+ T cell genes as a predictor to anti-PD1 therapy. Patients groups who benefitted from anti-PD1 therapy (Response, n = 22) and who did not (Nonresponse, n = 19) were analyzed for differential gene set enrichment by (a) heatmap and (b) GSEA as well as individual gene expression levels of (c) NLRC5, (d) HLA-B, B2M, (e) CD8A, granzyme A (GZMA), perforin (PRF1) and CD56. Bar represents the median value. P-values calculated using Mann–Whitney U test. NES, normalized enrichment score. (f) ROC curve for logistic regression model using NLRC5 expression. The numbers with arrow are showing false positive rate with 100% sensitivity. AUC (area under the curve) ± SE (standard error) is depicted. (g) Kaplan–Meier estimates of five year overall survival of patients with high and low NLRC5 gene expression, stratified by median expression (n = 20 and n = 21). Hazard ratio (HR) and 95% confidence interval (CI) was determined by multivariate analysis using Cox regression model (see Methods). **p < 0.01.
