ATRX mutation modifies the DNA damage response in glioblastoma multiforme tumor cells and enhances patient prognosis.

The presence of specific genetic mutations in patients with glioblastoma multiforme (GBM) is associated with improved survival outcomes. Disruption of the DNA damage response (DDR) pathway in tumor cells enhances the effectiveness of radiotherapy drugs, while increased mutational burden following tumor cell damage also facilitates the efficacy of immunotherapy. The ATRX gene, located on chromosome X, plays a crucial role in DDR.

Objective: Gliomas are a general designation for neuroepithelial tumors derived from the glial cells of the central nervous system. According to the histopathological and immunohistochemical features, the World Health Organization classifies gliomas into four grades. Bevacizumab is a monoclonal antibody targeting vascular endothelial growth factor that has been approved for the treatment of glioblastoma multiforme (GBM) as a second-line therapy.

Background: Brain tumors are the deadliest solid tumors in children and adolescents. Most of these tumors are glial in origin and exhibit strong heterogeneity, hampering the development of effective therapeutic strategies. In the past decades, patient-derived tumor organoids (PDT-O) have emerged as powerful tools for modeling tumoral cell diversity and dynamics, and they could then help defining new therapeutic options for pediatric brain tumors.

The overall goal of this work was to assess the ability of Natural Killer cells to kill cultures of patient-derived glioblastoma cells. Herein we report impressive levels of NK-92 mediated killing of various patient-derived glioblastoma cultures observed at ET (effector: target) ratios of 5:1 and 1:1. This enabled direct comparison of the degree of glioblastoma cell loss across a broader range of glioblastoma cultures.

Background: This systematic review and meta-analysis evaluates peripheral and CNS BDNF levels in glioma patients.
Methods: Following PRISMA guidelines, we systematically searched databases for studies measuring BDNF in glioma patients and controls. After screening and data extraction, we conducted quality assessment, meta-analysis, and meta-regression.
