Article Abstract
Background: Glioma, particularly glioblastoma, is a highly aggressive brain tumor with poor prognosis and limited treatment options. Recent research highlights the role of MANF (Mesencephalic Astrocyte Derived Neurotrophic Factor) in tumor biology, yet its specific mechanisms in glioma remain underexplored. This study aims to elucidate the role of MANF in glioma and its underlying mechanisms of action.
Methods: We conducted bioinformatics analysis using TCGA data to identify MANF-related pathways, followed by cellular assays and subcutaneous tumor models for functional validation. Experiments included Western blot and qRT-PCR analysis to investigate the effects of MANF on glioma cell proliferation, migration, and stemness gene expression.
Results: MANF was found to be highly expressed in tumor tissues and associated with poor prognosis in glioma patients. Endogenous MANF regulates tumor cells by modulating the TGF-β/SMAD4/p38 pathway, promoting stemness and enhancing malignant behaviors, including migration and invasion. Exogenous MANF, however, did not significantly affect stemness gene expression but contributed to glioma cell proliferation.
Conclusions: MANF emerges as a promising therapeutic target for glioma. This study clarifies MANF's specific mechanisms, offering insights into its potential for targeted glioma therapies.

Background: High-grade astrocytoma with piloid features (HGAP) was recently added to the WHO 2021 CNS classification system among the group of circumscribed astrocytic gliomas. These tumors present with high-grade piloid histology with similarities to glioblastoma. HGAPs in the pineal region become particularly challenging due to its deep location and proximity to deep venous structures, the midbrain, and the thalamus.

Background: Standard treatment for glioblastoma includes chemotherapy, alkylating agents such as temozolomide (TMZ); however, MGMT resistance leads to recurrence. Demethoxycurcumin (DMC) has been reported to inhibit cancer cell growth, induce apoptosis, and prevent metastasis in different cancer models. We investigated the DMC-induced apoptosis and autophagy via inhibition of the AKT/mTOR pathway in human glioma U87MG and T98G cell lines.

The prognosis of glioblastoma multiforme (GBM) remains dismal, despite standard treatment regimens. A key challenge in treating GBM is the persistence of glioma stem cells (GSCs) within the perivascular niche (PVN) - a protective tumor microenvironment (TME) that is often associated with inadequate drug penetration. Current preclinical models do not capture complexity of the human TME, particularly the vasculature and niche-specific interactions that drive GBM progression.

Background: Despite advances in understanding the effective connectivity (EC) of brain networks in leucine-rich glioma-inactivated 1 (LGI1) antibody encephalitis, the specific cause and underlying mechanisms of LGI1 encephalitis remain unclear.
Materials And Methods: The study included 27 patients with anti-LGI1 encephalitis and 28 age- and sex-matched normal controls. Amplitude of low-frequency fluctuation (ALFF) analysis identified altered brain regions.

Glioma therapy faces substantial challenges primarily due to the restrictive nature of the blood-brain barrier (BBB), limiting effective drug penetration and reducing therapeutic efficacy. Recent advancements in novel drug delivery systems (DDS), including exosome-mediated carriers, drug conjugates, and ultrasound-assisted delivery, have demonstrated promising results in overcoming these limitations. Exosomes offer superior biocompatibility, efficient BBB crossing, and natural cellular targeting capabilities; drug conjugates enable highly selective drug delivery through tumor-specific ligands; and ultrasound-assisted systems transiently disrupt the BBB to permit greater drug entry.
