UBE4B and neuroblastoma: To explore the roles of UBE4B expression and function in the pathogenesis of neuroblastoma, we evaluated the association of UBE4B gene expression with neuroblastoma patient outcomes and prognostic features, and we investigated the expression of UBE4B protein in neuroblastoma tumor samples and its association with known prognostic features and downstream intracellular signaling pathways.
