Comprehensive analyses of cuproptosis-related gene CDKN2A on prognosis and immunologic therapy in human tumors

Abstract Recent studies have identified a novel programmed cell death based on copper, named cuproptosis. However, as an anti-cuproptosis gene, the functional roles, definite mechanisms and prognostic value of CDKN2A in pan-cancer are largely unclear. The GEPIA2, cancer genome atlas (TCGA), the tumor immune estimation resource 2.0 and CPTAC databases were performed to validate the differential expression of CDKN2A in 33 tumors. The clinical features and survival prognosis analysis were conducted by GEPIA2 and UALCAN web tool. Genetic alteration analysis
