Abstract

This article aims to explore the impact of cyclin-dependent kinase 5 (CDK5) on the tumor microenvironment and its influence on radiotherapy resistance in lung cancer through bioinformatics analysis. Initially, dataset GSE148532 identifying 517 differentially expressed genes, with 67 downregulated and 450 upregulated. Functional enrichment analysis revealed these genes are primarily concentrated in the extracellular matrix. KEGG analysis indicated significant enrichment in the TGF-beta signaling pathway and cytokine-cytokine receptor interactions. Using Cytoscape, three key networks and the top ten intermediary genes were identified. Immune infiltration analysis showed significant correlations between CDK5 expression and macrophages, neutrophils, and dendritic cells.

CDK5 通过改变肿瘤微环境影响肺癌对放疗的耐受性

本文旨在通过生物信息学分析，探讨细胞周期蛋白依赖性激酶5（CDK5）对肿瘤微环境的影响及其对肺癌放疗耐药的影响。最初，数据集GSE148532鉴定出517个差异表达基因，其中67个下调，450个上调。功能富集分析显示，这些基因主要集中在细胞外基质中。KEGG 分析表明，TGF-beta 信号通路和细胞因子-细胞因子受体相互作用中存在大量富集基因。利用 Cytoscape，确定了三个关键网络和前十个中间基因。免疫浸润分析表明，CDK5的表达与巨噬细胞、中性粒细胞和树突状细胞之间存在显著相关性。
