Exploring new glioblastoma treatmentsGlutamine Metabolism Heterogeneity in Glioblastoma Unveils an Innovative Combination Therapy Strategy.
We investigated how glutamine metabolism impacts glioblastoma, paving the way for better treatments. By analyzing large datasets, we classified tumor profiles and examined their unique characteristics.
In a promising approach, we combined the glutaminase inhibitor CB839 with dihydroartemisinin (DHA) and found that this combination significantly affected cancer cell behaviors. This new therapy not only reduced glutamine metabolism but also increased cell death and hindered cancer cell movement.
Overall, our findings suggest that targeting glutamine metabolism with this combination could be an exciting strategy in fighting glioblastoma.

DHA inhibits glioma cell growthDihydroartemisinin suppresses glioma growth by repressing ERRα-mediated mitochondrial biogenesis.
We investigated how dihydroartemisinin (DHA), an antimalarial compound, impacts malignant gliomas, known for their aggressive nature and limited treatment options. Our study utilized various assays and animal models, revealing that DHA considerably reduced glioma cell growth, even in resistant strains. It prompted cell death through mitochondrial dysfunction and notably lowered the levels of ERRα, a gene responsible for mitochondrial biogenesis. Additionally, combining DHA with temozolomide enhanced its effectiveness. Overall, our findings highlight DHA's potential in targeting glioma progression by influencing cancer cell metabolism.

Hybrid enhances brain tumor treatmentChemical hybridization of sulfasalazine and dihydroartemisinin promotes brain tumor cell death.
We explored the impact of a new hybrid molecule made from sulfasalazine (SAS) and dihydroartemisinin (DHA) on glioma cells, which are tough brain tumors. While SAS didn’t show much promise on its own, DHA significantly reduced cell viability in a dose-dependent manner.
The newly synthesized hybrid, AC254, proved to be even more effective than the individual compounds alone. It not only killed more tumor cells but also affected the cell cycle and limited their movement. This study highlights the potential of combining established drugs to create more powerful treatments for brain tumors.

DHA induces cell death in glioblastomaω3-polyunsaturated fatty acids induce cell death through apoptosis and autophagy in glioblastoma cells: In vitro and in vivo.
We explored the potential of docosahexaenoic acid (DHA), an omega-3 fatty acid, in fighting glioblastoma, the most aggressive brain tumor. Our study examined various glioblastoma cell lines, discovering that DHA successfully induced cell death through mechanisms like apoptosis and autophagy. Additionally, findings from animal models suggested that DHA reduced tumor size through similar processes. This indicates that DHA could be a promising candidate for future therapies against glioblastoma, potentially improving treatment options for this challenging cancer type.

DHA enhances curcumin brain deliveryDocosahexaenoic acid-mediated, targeted and sustained brain delivery of curcumin microemulsion.
We examined the use of microemulsions (MEs) of curcumin combined with docosahexaenoic acid (DHA) for targeting brain tumors. Both intravenous and intranasal methods showed that the DHA microemulsions delivered significantly higher concentrations of curcumin to the brain, with the intranasal approach proving particularly effective. This enhanced delivery is due to DHA's ability to improve transport across the blood-brain barrier. Notably, we observed promising anticancer activity against human glioblastoma cells, suggesting that these formulations could be a valuable addition to brain cancer therapy.
