BACKGROUND: Adamantinoma craniopharyngioma (ACP) is a non-malignant tumour of unknown pathogenesis that frequently occurs in children and has malignant potential. The main treatment options are currently surgical resection and radiotherapy. These treatments can lead to serious complications that greatly affect the overall survival and quality of life of patients. It is therefore important to use bioinformatics to explore the mechanisms of ACP development and progression and to identify new molecules. METHODS: Sequencing data of ACP was downloaded from the comprehensive gene expression database for differentially expressed gene identification and visualized by Gene Ontology, Kyoto Gene, and gene set enrichment analyses (GSEAs). Weighted correlation network analysis was used to identify the genes most strongly associated with ACP. GSE94349 was used as the training set and five diagnostic markers were screened using machine learning algorithms to assess diagnostic accuracy using receiver operating characteristic (ROC) curves, while GSE68015 was used as the validation set for verification. RESULTS: Type I cytoskeletal 15 (KRT15), Follicular dendritic cell secreted peptide (FDCSP), Rho-related GTP-binding protein RhoC (RHOC), Modulates negatively TGFB1 signaling in keratinocytes (CD109), and type II cytoskeletal 6A (KRT6A) (area under their receiver operating characteristic curves is 1 for both the training and validation sets), Nomograms constructed using these five markers can predict progression of ACP patients. Whereas ACP tissues with activated T-cell surface glycoprotein CD4, Gamma delta T cells, eosinophils and regulatory T cells were expressed at higher levels than in normal tissues, which may contribute to the pathogenesis of ACP. According to the analysis of the CellMiner database (Tumor cell and drug related database tools), high CD109 levels showed significant drug sensitivity to Dexrazoxane, which has the potential to be a therapeutic agent for ACP. CONCLUSIONS: Our findings extend understandings of the molecular immune mechanisms of ACP and suggest possible biomarkers for the targeted and precise treatment of ACP.
背景:颅咽管瘤(ACP)是一种发病机制不明的非恶性肿瘤,常见于儿童,具有恶性潜能。目前主要的治疗选择是手术切除和放疗。这些治疗可能导致严重并发症,极大地影响患者的总体生存率和生活质量。因此,利用生物信息学探索ACP发生发展的机制并识别新分子具有重要意义。 方法:从综合基因表达数据库下载ACP的测序数据,用于差异表达基因鉴定,并通过基因本体论、京都基因和基因集富集分析(GSEA)进行可视化。加权基因共表达网络分析用于识别与ACP关联最紧密的基因。使用GSE94349作为训练集,采用机器学习算法筛选出5个诊断标志物,并使用受试者工作特征(ROC)曲线评估诊断准确性,同时使用GSE68015作为验证集进行验证。 结果:I型细胞角蛋白15(KRT15)、滤泡树突状细胞分泌肽(FDCSP)、Rho相关GTP结合蛋白RhoC(RHOC)、调节角质形成细胞中TGFB1信号负调节因子(CD109)和II型细胞角蛋白6A(KRT6A)(训练集和验证集的受试者工作特征曲线下面积均为1),使用这5个标志物构建的列线图可预测ACP患者的病情进展。而激活的T细胞表面糖蛋白CD4、γδT细胞、嗜酸性粒细胞和调节性T细胞在ACP组织中的表达水平高于正常组织,这可能有助于ACP的发病机制。根据CellMiner数据库(肿瘤细胞与药物相关数据库工具)分析,高CD109水平显示对右丙亚胺具有显著的药物敏感性,右丙亚胺有可能成为ACP的治疗药物。 结论:我们的研究结果扩展了对ACP分子免疫机制的认识,并为ACP的靶向精准治疗提出了可能的生物标志物。
