Twelve of the ninety-nine DUB genes were identified as differentially expressed in MB compared to non-tumor tissue (p < 0.0001) for the GO category of DNA repair in the Swartling dataset, including USP1, OTUB1, UCHL5, USP7, and PSMD14 (aka POH1) (Table 7). This evidence concerns the gene PSMD14 and neoplasm.
