Abstract:
Glioblastoma multiforme (GBM) represents the deadliest form of brain tumour, characterized by its low survival rate and grim prognosis. Cytokines released from glioma-associated microglia/macrophages are involved in establishing the tumour microenvironment, thereby crucially promoting GBM progression. MS4A6A polymorphism was confirmed to be associated with neurodegenerative and polymorphism disease pathobiology, but whether it participates in the regulation of GBM and the underlying mechanisms is still not elucidated. Here, we found that MS4A6A was significantly upregulated in GBM patient samples. The results from the single-cell RNA-sequencing (scRNA-seq) database and immunostaining demonstrated the specific expression of MS4A6A in microglial cells. In vitro, microglial overexpression of MS4A6A stimulated the proliferation and migration of glioblastoma cells. Moreover, high MS4A6A mRNA expression was related to poor prognosis in GBM patients. Our study highlights the potential of MS4A6A as a promising biomarker for GBM, which may provide novel strategies for its prevention, diagnosis and treatment.
Insights
MS4A6A is upregulated in glioblastoma (GBM), a deadly brain tumor. Its expression in microglia promotes GBM cell growth and migration, indicating MS4A6A is a potential biomarker for improved GBM diagnosis and treatment.
Area of Science:
- Neuro-oncology
- Immunology
- Genetics
Background:
- Glioblastoma multiforme (GBM) is an aggressive brain tumor with poor prognosis.
- Glioma-associated microglia/macrophages contribute to the tumor microenvironment and GBM progression.
- MS4A6A gene variants are linked to neurodegenerative diseases, but its role in GBM is unclear.

- To determine the expression pattern and functional impact of MS4A6A in GBM.
- To evaluate MS4A6A as a potential biomarker for GBM.
Main Methods:
- Analysis of MS4A6A expression in GBM patient samples.
- Utilized single-cell RNA-sequencing (scRNA-seq) database and immunostaining to identify MS4A6A expression in microglial cells.
- In vitro experiments to assess the effect of microglial MS4A6A overexpression on glioblastoma cell proliferation and migration.
Main Results:
- MS4A6A was significantly upregulated in GBM patient samples.
- MS4A6A expression was specifically localized to microglial cells in the GBM microenvironment.
- Overexpression of MS4A6A in microglia promoted glioblastoma cell proliferation and migration.
