Pearson analysis showed that the MRPScore was positively correlated with antigen processing machinery, nucleotide excision repair and mismatch repair and negatively correlated with CD8+ T effectors and immune checkpoints in the known gene signatures of the TCGA-KIRC and CPTAC-ccRCC cohorts (Figures 4G,H). Here, CD8A is linked to nonpapillary renal cell carcinoma.
