Aim:
To investigate the role of SUV39H2 in glioblastoma (GBM) stem cells (GSCs) and assess whether co-targeting SUV39H2 and SUV39H1 more effectively disrupts GSC maintenance, offering a potential strategy to improve GBM treatment.
Methods:
Single-cell RNA-seq was used to assess SUV39H2 expression in GSCs. GSC growth and stemness were evaluated using tumorsphere formation assay and extreme limiting dilution assay. Gene expression at the mRNA and protein levels was measured by RT-qPCR and western blot, respectively. Publicly available datasets were analyzed to investigate SUV39H2 expression patterns and its clinical prognostic significance in GBM and glioma.
Results:
SUV39H2 is overexpressed in GSCs relative to non-stem GBM cells. Its depletion impairs GSC proliferation and stemness. Co-targeting SUV39H2 and SUV39H1 enhances GSC disruption. High SUV39H2 expression correlates with poor glioma prognosis.
Conclusion:
SUV39H2 is a novel regulator of GSC maintenance. Dual targeting of SUV39H2 and SUV39H1 May offer a potential therapeutic approach for GBM.
