Abstract Objectives: Glioblastoma multiforme (GBM) is a highly aggressive brain tumor characterized by extensive transcriptional and epigenetic dysregulation. Brother of the Regulator of Imprinted Sites (BORIS/CTCFL) has been implicated in oncogenic transcriptional programs in several cancers, but its role in GBM remains poorly defined. This study aimed to characterize BORIS-associated transcriptional programs in GBM and to assess their functional relevance using integrative computational and experimental approaches. Methods: Transcriptomic data from The Cancer Genome Atlas (TCGA)-GBM and Genotype-Tissue Expression (GTex) brain cortex were analyzed following batch correction, differential expression analysis, and gene ontology enrichment. TCGA-GBM samples were… More >

Abstract Objective: Glioblastoma (GB) therapy is challenged by tumor heterogeneity and multidrug resistance (MDR), highlighting the need for effective therapies. This study aimed to explore the combined anticancer effects of Sunitinib (SNB) and Fenofibrate (FEN) on U87 cells. Methods: U87 cells were exposed to SNB, FEN, or their combination for 24 h, followed by evaluations of cell viability, migration, and clonogenic survival using MTT, scratch, and colony formation assays. Intracellular reactive oxygen species (ROS) were quantified via the 2^′, 7^′-dichlorofluorescein assay, while mitochondrial membrane potential (MMP) was assessed using JC-1 red/green fluorescence. Molecular docking was performed to… More > Graphic Abstract

Abstract Objectives: Glioblastoma multiforme (GBM) is highly resistant to apoptosis. This study investigates the role of Selenoprotein M (SELENOM), a redox-regulating protein, in the response of human glioblastoma A-172 cells to staurosporine (STS) and hyperthermia. Methods: A stable SELENOM-knockdown (SELENOM-KD) cell line was created. We measured reactive oxygen species (ROS), mitochondrial membrane potential (ΔΨm), cell death, and apoptotic gene expression. Results: SELENOM-KD increased basal ROS levels and induced mitochondrial dysfunction. It sensitized cells to STS-induced apoptosis, enhancing the upregulation of pro-apoptotic genes. Conversely, under hyperthermia (42°C), SELENOM-KD cells exhibited significant thermoresistance, with 52% survival vs. 99% death More > Graphic Abstract

Abstract Objectives: Glioblastoma (GBM) is a prevalent malignant brain tumor prone to drug resistance. We previously found a strong correlation between SH3 domain GRB2-like endophilin B1 (SH3GLB1) and superoxide dismutase 2 (SOD2), which converts O₂ to hydrogen peroxide (H₂O₂). Prior studies show that H₂O₂ redox signaling is vital for physiological processes and can drive tumor progression. Therefore, we aim to define how H₂O₂ signaling regulates SH3GLB1 and AKT (protein kinase B) pathways in GBM and to assess whether modulating H₂O₂ reverses temozolomide (TMZ) resistance. Methods: We used cultured cells and pharmacological inhibitors and activators to confirm the significance of… More > Graphic Abstract

Abstract Background: Glioblastoma (GBM) prognosis has seen little improvement over the past two decades. While immunotherapy has revolutionized cancer treatment, its impact on GBM remains limited. To characterize the evolving research landscape and identify future directions in GBM immunotherapy, we conducted a comprehensive bibliometric review. Methods: All literature related to immunotherapy in GBM from 1999 to 2024 was collected from the Web of Science Core Collection. CtieSpace and VOSviewer were used to conduct bibliometric analysis and visualize the data. Results: Bibliometric analysis identified 5038 publications authored by 23,335 researchers from 4699 institutions across 96 countries/regions, published in… More >

Abstract Background: Glioblastoma is a lethal primary brain tumor that is therapeutically challenging due to its rapid progression. Interferon-gamma (IFN-γ) signaling is altered in glioblastoma. Moreover, proteolytic enzymes, known as proteases, have been linked to the invasive growth of cancerous cells. In this study, we aimed to identify a glioblastoma-associated protease group and to determine its potential connection with IFN-γ signaling. Methods: Using cancer expression databases, we analyzed the differential expression of 35 proteases in glioblastoma and healthy brain tissue, and the relevance of their deregulation to patient survival. We also explored correlations between IFN-γ signaling… More >

Abstract Objectives: Cisplatin (CDDP) therapy for glioblastoma (GBM) is linked with several limitations, which include poor penetration of the blood-brain barrier (BBB), systemic toxicity, and the development of drug resistance mechanisms implicating oxidative stress dysregulation and compromised apoptotic pathways. This study evaluates C-Phycocyanin (C-PC) as a potential adjuvant to enhance CDDP efficacy by modulating redox balance and apoptosis. Methods: GBM cells (U87 and U87-EGFRvIII) were treated with CDDP, C-PC, or their combination. Cell viability was assessed by MTT assay; apoptosis was evaluated by DAPI staining and Western blot analysis of cleaved Caspase-3 and poly (ADP-ribose) polymerase… More > Graphic Abstract

Abstract Objectives: Glioblastoma is a prevalent malignant brain tumor, and the actions of the long non-coding RNA HOXA10-AS in its invasion and migration remain unclear. Here, the function of HOXA10-AS in glioblastoma cell invasion and migration and associated mechanisms were investigated. Methods: HOXA10-AS was knocked down in glioblastoma cells, and Transwell and wound healing assays were conducted to elucidate its impacts on cell invasion and migration. Western blotting and quantitative reverse transcription polymerase chain reaction (qRT-PCR) assessed HOXA10-AS’s impact on the epithelial-mesenchymal transition (EMT). Microarray analysis identified differentially expressed genes, complemented by bioinformatics approaches to explore… More >

Abstract Background: Glioblastoma (GBM) remains the most aggressive primary brain tumour in adults, marked by pronounced cellular heterogeneity, diffuse infiltration, and resistance to conventional treatment. In recent years, transcriptomic profiling has provided valuable insights into the molecular mechanisms that govern the progression of glioblastoma. This systematic review aims to synthesise the current literature on dysregulated gene expression in GBM, focusing on gene signatures associated with stemness, immune modulation, extracellular matrix remodelling, metabolic adaptation, and therapeutic resistance. Methods: We conducted a systematic search of PubMed, The Cancer Genome Atlas (TCGA), Chinese Glioma Genome Atlas (CGGA), and the GlioVis… More >

Abstract Background: Glioblastoma (GBM) is one of the most malignant types of central nervous system tumors. Oxygen deprivation in the tumor microenvironment is thought to be an important factor in promoting GBM progression. However, the mechanisms of hypoxia-promoted tumor progression remain elusive. Methods: Alternative splicing of diacylglycerol kinase gamma (DGKG)-Δ exon13 was amplified and verified by PCR-Sanger sequencing. The functions of DGKG and DGKG-Δ exon13 were analyzed by Cell counting kit-8 (CCK-8), Transwell, Matrigel-transwell experiments, and in vivo orthotropic GBM animal models. Transcriptome analyses were done to find out the regulated genes. Results: In this study, we found… More > Graphic Abstract
