YY1 and pancreatic adenocarcinoma: Using univariate Cox proportional-hazard regression (HR) model to predict the prognostic risk of the two genes in pan-cancer, we found that YY1 was an adverse prognostic factor (p < 0.05, HR > 0) for OS in PAAD, LUAD, and KIRP and a protective prognostic factor in OV and KIRC (p < 0.05, HR < 0).
