Abstract

Extensive research indicates that the kinesin superfamily (KIFs) regulates tumor progression. Nonetheless, the potential prognostic and therapeutic role of KIFs in glioma has been limited. Four independent cohorts from The Cancer Genome Atlas (TCGA) database and the Chinese Glioma Genome Atlas (CGGA) database were generated into a large combination cohort for identification of the prognostic signature. Following that, systematic analyses of multi-omics data were performed to determine the differences between the two groups. In addition, IDH1 was selected for the differential expression analysis. The signature consists of five KIFs (KIF4A, KIF26A, KIF1A, KIF13A, and KIF13B) that were successfully identified. Receiver operating characteristic (ROC) curves indicated the signature had a suitable performance in prognosis prediction with the promising predictive area under the ROC curve (AUC) values. We then explored the genomic features differences, including immune features and tumor mutation status between high- and low-risk groups, from which we found that patients in the high-risk group had a higher level of immune checkpoint modules, and IDH1 was identified mutated more frequently in the low-risk group. Results of gene set enrichment analysis (GSEA) analysis showed that the E2F target, mitotic spindle, EMT, G2M checkpoint, and TNFa signaling were significantly activated in high-risk patients, partially explaining the differential prognosis between the two groups. Moreover, we also verified the five signature genes in the Human Protein Atlas (HPA) database. According to this study, we were able to classify glioma patients based on KIFs in a novel way. More importantly, the discovered KIFs-based signature and related characteristics may serve as a candidate for stratification indicators in the future for gliomas.

摘要

大量研究表明驱动蛋白超家族(KIFs)调节肿瘤进展。然而,KIFs 在神经胶质瘤中的潜在预后和治疗作用一直受到限制。从癌症基因组图谱(TCGA)数据库和中国神经胶质瘤基因组图谱(CGGA)数据库生成了四个独立的队列,将其纳入一个大型联合队列中,以确定预后特征。之后,对多组学数据进行了系统分析,以确定两组之间的差异。此外,选择 IDH1 进行差异表达分析。该特征由五个 KIFs(KIF4A、KIF26A、KIF1A、KIF13A 和 KIF13B)组成,这些 KIFs 已被成功识别。接收器操作特征(ROC)曲线表明,该特征在预后预测方面具有良好的性能,ROC 曲线下有希望的预测面积(AUC)值。然后,我们探索了基因组特征差异,包括高、低风险组之间的免疫特征和肿瘤突变状态,从中我们发现高风险组患者的免疫检查点模块水平更高,低风险组中 IDH1 更频繁地发生突变。基因集富集分析(GSEA)分析结果表明,高危患者的 E2F 靶标、有丝分裂纺锤体、EMT、G2M 检查点和 TNFa 信号显著激活,部分解释了两组之间的差异预后。此外,我们还在人类蛋白质图谱(HPA)数据库中验证了这五个特征基因。根据这项研究,我们能够以一种新的方式根据 KIFs 对神经胶质瘤患者进行分类。更重要的是,发现的基于 KIFs 的特征和相关特征可能成为未来神经胶质瘤分层指标的候选者。
