In-Depth Summary of Intersected Hub-Genes Between Low-Grade and High-Grade Gliomas, from Bioinformatics and Literature Reports

Gliomas are malignant tumours arising from glial cells in the central nervous system (CNS), presenting significant clinical challenges. High-grade gliomas (HGGs) are particularly concerning as they are the primary cause of CNS cancer-related deaths. Low-grade gliomas (LGGs), which include diffuse types, represent only 15% of all glioma cases. this review aims to identify the critical hub genes associated with HGG and LGG, understand their proliferation, apoptosis, and mutation role in glioma, and their therapeutic potential as well. First, we identified the gene interaction networks by employing bioinformatics techniques, such as differential expression analysis, Venn enrichment, Cytoscape, and CytoHubba analyses. Next, we summarized the role of hub genes, addressing recent advancements and emerging evidence related to the identified hub genes to provide a comprehensive understanding. The analysis revealed ten hub genes: CCNB1, TOP2A, CENPF, NEK2, ASPM, TPX2, PBK, RRM2, KIF15, and ATAD2. Most hub genes showed elevated expression in HGG compared to LGG, and a strong positive correlation with glioma pathology. Also, might hold significant therapeutic potential, particularly CCNB1, CENPF, NEK2, and TPX2, due to their crucial biological functions and the results of gene mania analysis. This review offers an overview and comprehensive knowledge of the hub genes in glioma pathology, which may inform future research and clinical trials aimed at developing targeted therapeutic strategies.
