研究目的:

本研究拟进行综合转录组分析,以确定与 PBC 和 HCC 共同相关的基因。在 PBC 和 HCC 数据集中独立鉴定差异表达基因(DEGs),并使用 WGCNA 进一步完善了交叉基因。在共享基因集的基础上,利用 LASSO Cox 回归建立了 HCC 的预后风险模型,并在独立队列中验证该模型的预测性能。结合风险评分和临床参数构建nomogram 模型,以提高预后效用。此外,探讨风险模型与体细胞突变特征、免疫浸润特征、药物敏感性和通路富集的关联。这项工作提供了一个连接免疫介导的肝损伤和肝癌发生的分子框架,并为 HCC 的风险分层提供了潜在的工具。  

Objectives of Study:

This study intends to conduct an integrated transcriptome analysis to identify genes commonly associated with PBC and HCC. Differentially expressed genes (DEGs) were independently identified in PBC and HCC datasets, and WGCNA was used to further refine the overlapping genes. Based on the shared gene set, a prognostic risk model for HCC was established using LASSO Cox regression, and the predictive performance of this model was validated in an independent cohort. A nomogram model was constructed by combining risk scores and clinical parameters to improve prognostic utility. In addition, the associations of the risk model with somatic mutation features, immune infiltration characteristics, drug sensitivity, and pathway enrichment were explored. This work provides a molecular framework connecting immune-mediated liver injury and hepatocarcinogenesis and offers a potential tool for risk stratification of HCC.
