Development and validation of NAD+ metabolism-related gene signature in prognosis prediction of hepatocellular carcinoma

Liver cancer is a prevalent and deadly malignancy worldwide, with a rising incidence rate. In this study, we focused on the role of NAD+ metabolism-related genes in liver cancer prognosis prediction. We identified key genes among NAD+ metabolism-related genes and explored their relationship with cancer staging and prognosis using gene expression data. A risk score model was constructed to assess cancer risk and survival status. The model demonstrated significant predictive potential for survival outcomes. Furthermore, we analyzed the risk scores in different populations and performed functional enrichment analyses to gain insights into the biological processes involved. Our study highlights the clinical value and significance of NAD+ metabolism-related genes in liver cancer. The findings provide a foundation for personalized treatment strategies and open new avenues for further research in liver cancer management. ### Competing Interest Statement The authors have declared no competing interest.
