CASP4 and neoplasm: In this study, a prognostic model of 9 genes (CASP3, CASP4, CASP8, CASP9, GSDMC, IL18, IL6, PLCG1, and PRKACA) was constructed based on bioinformatics analysis with the survival data of LGG patients in the TCGA and CGGA cohorts and validated it by both clinical prognosis and correlation with tumor immunity.
