NUDT1 and hepatocellular carcinoma: Gene set enrichment analysis showed that biological pathways related to cell cycle, fatty acid metabolism, bile acid and bile salt metabolism, and PLK1 signaling were associated with NUDT1, as were the gene ontology terms “DNA binding transcription activator activity,” “RNA polymerase II,” “nuclear division,” and “transmembrane transporter activity.” Our study thus demonstrates that NUDT1 is a prognostic biomarker with therapeutic potential in HCC patients.
