Abstract

Background: Since telomere length and DNA methylation both correlate with hepatocellular carcinoma (HCC) prognosis, telomere-methylation genes could be novel prognostic markers for HCC.

Method: This study first investigated the interaction between telomere length and DNA methylation in HCC through Mendelian randomization analysis. Then, this study identified telomere-methylation genes in HCC by employing the TCGA-LIHC cohort, and explored the expression patterns of these genes in the tumor microenvironment of HCC and potential underlying mechanisms. Finally, the HCC risk-scoring model and prognostic model based on these genes were established, and the performance of the model was assessed.

Result: The findings revealed a bidirectional relationship between telomere length and DNA methylation in HCC. Fifty telomere-methylation genes were identified, and the prognosis-related telomere-methylation genes were closely associated with Treg and Tprolif cell subsets within the HCC tumor microenvironment. Telomere-methylation genes could potentially impact the prognosis of HCC patients by modulating chromosome stability and regulating the cell cycle. Additionally, the constructed risk scoring model and prognostic prediction model showcased compelling clinical applicability, as evidenced by the receiver operating characteristic curve, the decision curve analysis, and the calibration curves.

Conclusion: This study elucidated the potential of telomere-methylation genes as prognostic biomarkers for HCC and paves the way for novel approaches in prognostication and treatment management for HCC patients.

期刊介绍： Clinics and Research in Hepatology and Gastroenterology publishes high-quality original research papers in the field of hepatology and gastroenterology. The editors put the accent on rapid communication of new research and clinical developments and so called "hot topic" issues. Following a clear Editorial line, besides original articles and case reports, each issue features editorials, commentaries and reviews. The journal encourages research and discussion between all those involved in the specialty on an international level. All articles are peer reviewed by international experts, the articles in press are online and indexed in the international databases (Current Contents, Pubmed, Scopus, Science Direct). Clinics and Research in Hepatology and Gastroenterology is a subscription journal (with optional open access), which allows you to publish your research without any cost to you (unless you proactively chose the open access option). Your article will be available to all researchers around the globe whose institution has a subscription to the journal.
