ETS 家族调节免疫反应和靶向治疗的药物效率,但它们在黑色素瘤中的作用很大程度上尚不清楚。在这项研究中,ETS家族在多个公共数据集中进行了系统分析。使用生物信息学工具来表征 ETV7 在黑色素瘤中的功能。使用LASSO Cox回归方法构建预后模型。我们发现 ETV7 是黑色素瘤中唯一具有显着预后相关性的差异表达基因。七个独立数据集的富集分析表明 ETV7 参与各种免疫相关途径。 ETV7 尤其与 CD8+ T 细胞浸润呈强正相关。基于ETV7及其hub基因的预后模型在训练和测试数据集上表现出了较好的预测价值。因此,ETV7 可以潜在地调节黑色素瘤的免疫微环境。
The ETS family modulates immune response and drug efficiency to targeted therapies, but their role in melanoma is largely unclear. In this study, the ETS family was systematically analyzed in multiple public data sets. Bioinformatics tools were used to characterize the function of ETV7 in melanoma. A prognostic model was constructed using the LASSO Cox regression method. We found that ETV7 was the only differentially expressed gene with significant prognostic relevance in melanoma. Enrichment analysis of seven independent data sets indicated ETV7 participation in various immune-related pathways. ETV7 particularly showed a strong positive correlation with CD8+ T cell infiltration. The prognostic model based on ETV7 and its hub genes showed a relatively good predictive value in training and testing data sets. Thus, ETV7 can potentially regulate the immune microenvironment in melanoma.
