ABSTRACT Objectives Glioblastoma multiforme (GBM) is considered the most assailant subtype of gliomas, presenting a formidable obstacle because its inherent resistance to temozolomide (TMZ). This study aimed characterize function lncRNA NEAT1 in facilitating advancement gliomas. Methods The expression level glioma tissues and cells was detected by qRT‐PCR. RNA interference experiment, cell proliferation assay, FITC/PI detection immunoblotting, bioinformatics prediction, double luciferase reporter gene immunoprecipitation (RIP) SLDT assay correlation analysis clinical samples were performed explore regulatory effects NEAT1, miR‐454‐3p Cx43 their role malignant progression GBM. vivo investigated an intracranial tumor formation experiment mice. Results results showed that recurring gliomas displayed elevated levels compared primary suppression led restoration sensitivity GBM TMZ. functioned as competitive endogenous against miR‐454‐3p. Connexin 43 identified target. found regulate gap junctional intercellular communication modulating 43, thereby impacting response TMZ chemotherapy. Downregulation resulted enhanced chemosensitivity extended survival Conclusions Overall, these indicated NEAT1/miR‐454‐3p/Connexin pathway influences could offer potential new strategy for treating

Abstract In recent years, it has been increasingly recognized that tumor growth relies not only on support from the surrounding microenvironment but also tumors capacity to adapt – and actively manipulate its niche. While targeting angiogenesis modulating local immune environment have explored as therapeutic approaches, these strategies yet yield effective treatments for brain remain under refinement. More recently, nervous system itself a critical environmental cancer, with extensive neuro-tumoral interactions observed both intracranially in extracranial sites containing neural components. brain, between glioma cells well metastatic lesions components clinical implications diagnostics, risk assessments, neurological sequelae, development of innovative therapeutics. Here, we review dynamics, emphasizing aspects relevant neurosurgical practice.

The discovery of cellular tumor networks in glioblastoma, with routes malignant communication extending far beyond the detectable margins, has highlighted potential supramarginal resection strategies. Retrospective data suggest that these approaches may improve long-term disease control. However, their application is limited by proximity critical brain regions and vasculature, posing challenges for validation randomized trials. Anterior temporal lobectomy (ATL) a standardized surgical procedure commonly performed patients pharmacoresistant lobe epilepsy. Translating ATL approach from epilepsy surgery to neuro-oncological field provide model investigating glioblastomas located anterior lobe. ATLAS/NOA-29 trial prospective, multicenter, multinational, phase III controlled designed compare standard gross-total (GTR) newly-diagnosed glioblastoma. primary endpoint overall survival (OS), superiority defined significant improvements OS non-inferiority co-primary endpoint, quality life (QoL; "global health" domain European organization research treatment cancer (EORTC) QLQ-C30 questionnaire).
