The interplay between angiogenesis and the immune system is intricate, with the potential to either enhance or repress the immune response. Angiogenesis-related genes (ARGs) are significant for the development, growth, and immune response of tumors. Understanding their prognostic significance and molecular characteristics in skin melanoma can guide and refine therapeutic strategies. Here, we analyzed the TCGA-SKCM dataset and explored the ARG expression between skin melanoma and normal skin, as well as between primary and metastatic tumors. Kaplan-Meier analyses were conducted to assess the overall, disease-specific, and progression-free survival. Additionally, comprehensive immune profiling was carried out utilizing advanced bioinformatics tools to evaluate immune checkpoint gene expression and immune cell infiltration. Our findings highlighted strong prognostic associations for , , and . Molecular characterization showed a significant upregulation of , , , , , , , , , , and in SKCM compared to that in normal skin. Immune analyses, including Immune Checkpoint Gene Analysis, Immune Infiltration Analysis, Immune Cell Analysis, and Immune Cell Profiling, demonstrated both positive and negative correlations between ARGs expression and immune cell infiltration, emphasizing the multifaceted role of these genes in immune modulation. The study underscores the prognostic relevance of ARGs in skin melanoma and their contribution to tumor immunity. Overall, our findings expand our understanding of melanoma immunogenetics, suggesting the use of angiogenesis-related genes not merely as vascular regulators, but also as immune modulators.
血管生成与免疫系统之间的相互作用错综复杂,具有增强或抑制免疫反应的潜力。血管生成相关基因(ARGs)对肿瘤的发生、发展和免疫反应具有重要意义。了解它们在皮肤黑色素瘤中的预后意义和分子特征可以指导并优化治疗策略。在此,我们分析了TCGA-SKCM数据集,探讨了皮肤黑色素瘤与正常皮肤之间以及原发性和转移性肿瘤之间的ARGs表达情况。进行了Kaplan-Meier分析以评估总生存期、疾病特异性生存期和无进展生存期。此外,利用先进的生物信息学工具进行了全面的免疫分析,以评估免疫检查点基因表达和免疫细胞浸润情况。我们的研究结果突出了[具体基因1]、[具体基因2]和[具体基因3]的强预后相关性。分子特征显示,与正常皮肤相比,SKCM中[具体基因4]、[具体基因5]、[具体基因6]、[具体基因7]、[具体基因8]、[具体基因9]、[具体基因10]、[具体基因11]、[具体基因12]和[具体基因13]显著上调。免疫分析,包括免疫检查点基因分析、免疫浸润分析、免疫细胞分析和免疫细胞谱分析,表明ARGs表达与免疫细胞浸润之间存在正相关和负相关,强调了这些基因在免疫调节中的多方面作用。该研究强调了ARGs在皮肤黑色素瘤中的预后相关性及其对肿瘤免疫的贡献。总体而言,我们的研究结果扩展了我们对黑色素瘤免疫遗传学的理解,表明血管生成相关基因不仅可作为血管调节剂,还可作为免疫调节剂。
