TCGA-based analyses also highlight that the mRNA expression levels of UBR5 and PDL1 are highly correlated in many other cancer types, such as pancreatic adenocarcinoma (PAAD), thymoma (THYM), uveal melanoma (UVM), and prostate adenocarcinoma (PRAD) (Figure S1). Here, UBR5 is linked to pancreatic adenocarcinoma.
