Summary: The study revealed that 5Z-7-oxozeaenol plays an important role in increasing the sensitivity of glioblastoma cells to chemotherapy, potentially serving as an effective adjuvant to current chemotherapeutic regimens. It also highlighted the continuous involvement of mitogen-activated protein kinase in tumorigenesis following chemotherapy.

Summary: This study explores the use of exosomes secreted by allogeneic bone marrow mesenchymal stem cells as a nanocarrier for glioblastoma therapy. With the decoration of a specific peptide, the nanocarrier exhibits enhanced targeting ability for TMZ resistant GBM. Additionally, the system can deliver targeted siRNA to restore drug sensitivity and achieve treatment of drug-resistant GBM.

Summary: In this review, the researchers summarize current knowledge on lipid metabolism in GBM, specifically focusing on the development of TMZ resistance. Dysregulated lipid metabolism has been identified as a contributing factor to TMZ resistance in GBM, and targeting lipid metabolism may offer a promising approach for overcoming resistance and improving outcomes. The review highlights key metabolites and proteins involved in lipid synthesis, uptake, and utilization, as well as recent advances in metabolomics to study lipid metabolism in GBM.

Summary: Glioblastoma (GBM) is a highly malignant brain tumor that is resistant to current therapies. This review focuses on the resistance mechanisms of GBM, particularly towards temozolomide (TMZ), and summarizes the recent findings on the intrinsic and extrinsic mechanisms of chemoresistance in GBM stem cells (GSCs). It also discusses novel therapeutic strategies, such as molecular targeting, autophagy inhibition, oncolytic viral therapy, drug repositioning, and targeting of GSC niches, to eliminate GSCs and improve GBM therapy.

Summary: CRNDE is a poor prognosis factor for GBM patients, upregulated in TMZ-resistant patients, and closely associated with chemotherapeutic response to TMZ treatment. Knockdown of CRNDE significantly reduces glioma cell viability and proliferation, enhances cell apoptosis, and improves sensitivity to TMZ treatment.

Summary: Treatment for glioblastoma has been improved through the non-invasive addition of tumor treating fields (TTFields). TTFields decrease the growth of glioblastoma cells and may have therapy-specific vulnerabilities. The activity of PDGFR alpha may serve as a pro-survival mechanism for TTFields.

Summary: Riluzole demonstrates significant growth-inhibitory effects on all GBM cell lines in a time- and dose-dependent manner. It synergistically enhances the antitumor effect of TMZ in MGMT-positive GBM cell lines, while suppressing MGMT expression and TMZ-induced MGMT upregulation. Combinatorial TMZ/riluzole treatment significantly suppresses tumor growth in an intracranial MGMT-positive GBM model, suggesting it as a promising therapeutic regimen for MGMT-positive GBMs.

Summary: Chemoresistance is a challenge in the treatment of glioblastoma (GBM), and the activity of O6-methylguanine-DNA methyltransferase (MGMT) and signal transducer and of transcription 3 (STAT3) have been linked to GBM resistance. Resveratrol (Res) inhibits tumor growth and improves chemosensitivity by targeting STAT3 signaling. This study found that Res effectively improved chemosensitivity of GBM cells to temozolomide (TMZ) and downregulated STAT3 activity, leading to inhibition of cell proliferation, migration, and induction of apoptosis. The combination therapy of Res and TMZ also reversed TMZ resistance and decreased MGMT and STAT3 levels. Therefore, Res may be an ideal candidate for combined chemotherapy with TMZ in GBM.

Summary: Cancer immunotherapy has had limited success, but nanoparticles have emerged as crucial tools in targeting tumor-associated macrophages (TAMs) and improving therapy outcomes. Current strategies include restricting TAMs survival, inhibiting TAMs recruitment, and repolarizing tumor-supportive TAMs to an antitumor phenotype.

Summary: This study found that mTBI patients with PCS had lower average MVF in the bilateral cerebral WM compared to controls, as well as significantly decreased myelin volume in the corpus callosum and brainstem. Total myelin volume was also reduced in these patients. Additionally, there was a significant correlation between myelin volume and neuropsychological test scores only in the bilateral cerebral WM and verbal learning test.

Summary: This study assessed the current status of artificial intelligence (AI) applications for microsatellite instability (MSI) prediction based on whole slide images (WSIs), and suggested a better study design. The AI models showed promising results in predicting MSI, but the limitations included small datasets and lack of external validation. Future studies with larger datasets are needed to implement AI models in routine diagnostic practice for MSI prediction.

Summary: This study investigated the role of tumor budding (TB) in gynecological cancers and found that TB is associated with poor survival outcomes. TB is related to epithelial-mesenchymal transition, microvessel density, and decreased hormone receptor expression. TB can be used as a poor prognostic marker for gynecologic cancers.

Summary: In this study, two cases of rare angiomatoid fibrous histiocytomas (AFH) were reported, one in the brain parenchyma and the other in the spinal cord. Molecular investigations revealed that both cases harbored FET:CREB fusion. A comprehensive review of 40 cases of central nervous system AFHs/myxoid mesenchymal tumors showed that they predominantly occurred in children and young adults, were dura-based, and were associated with EWSR1 rearrangements.

Summary: This study developed a machine learning-based model to identify preoperative multiparametric MR imaging markers associated with prognosis in glioblastoma patients. The model found that nonenhancing T2 high-signal-intensity lesions with the relatively low normalized CBV, low volume transfer constant values, and the lowest ADC values could serve as useful prognostic imaging markers for predicting survival outcomes in patients with glioblastoma.

Summary: The MYB/MYBL1::QKI fusion activates the oncogene MYB and deletes the tumor suppressor gene QKI. Previously, this fusion was only reported in angiocentric glioma (AG) and diffuse low-grade glioma. This study compares two tumors with the MYB/MYBL1::QKI fusion: a diffuse pediatric-type high-grade glioma (DPedHGG) in an 11-year-old boy and an AG in a 46-year-old woman. Characterization using immunohistochemistry, next-generation sequencing, and methylation profiling reveals their molecular characteristics and supports the presence of MYB/MYBL1 alterations in higher-grade gliomas.

Summary: This study presents the clinicopathological and molecular genetic characteristics of a neuroepithelial tumor (NET) with EWSR1::PATZ1 fusion, which has recently been discovered in rare central nervous system tumors and soft tissue sarcomas. Two cases of this fusion were identified, with the pediatric case showing a high-grade tumor and longer survival compared to conventional glioblastoma. The TERT promoter mutation may serve as an indicator of high-grade behavior in PATZ1 fusion NET.
