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. This evidence concerns the gene KLHDC10 and hepatocellular carcinoma.
