In our study, we developed a signature comprising 17 PCD-related genes (ENO1, CDK4, RPS17, PDLIM1, KLHDC10, IGFBP3, UBE2E1, CBS, UBB, YWHAQ, SPP1, USF2, STAT6, PCK2, CACYBP, HDAC1, CD79A), which demonstrated predictive capability for OS in patients with HCC. Here, UBB is linked to hepatocellular carcinoma.
