CCNE1 and cancer: By analyzing the pan-cancer cohorts in the GEPIA2 database, we discovered that the expression of CCNE1 was negatively correlated with the OS time of patients in the ACC (HR = 2.7), BRCA (HR = 1.6), KIRC (HR = 2.0), KIRP (HR = 3.7), LGG (HR = 1.6), LIHC (HR = 1.7), LUAD (HR = 1.5) and mesothelioma (MESO) (HR = 2.9) cohorts.
