Omega-3 fatty acids induce cell deathω3-polyunsaturated fatty acids induce cell death through apoptosis and autophagy in glioblastoma cells: In vitro and in vivo.
We delved into the potential of omega-3 polyunsaturated fatty acids, specifically docosahexaenoic acid (DHA), to combat glioblastoma, one of the most aggressive brain tumors.
In our study, we found that DHA treatment led to cell death in glioblastoma cells, as evidenced by signs of apoptosis and increased autophagy. Furthermore, tests in transgenic mice revealed a notable reduction in tumor size and increased activity reflected in cell death markers.
While these findings suggest a promising avenue for GBM treatment, further research is needed to fully understand how omega-3 fatty acids could be integrated into cancer therapies.

Eicosapentaenoic acid impacts tumorsOmega-3 fatty acids decrease CRYAB, production of oncogenic prostaglandin E and suppress tumor growth in medulloblastoma.
We investigated the effects of eicosapentaenoic acid (EPA) alongside docosahexaenoic acid (DHA) on medulloblastoma, a common and aggressive brain tumor in children.
In our study, we treated medulloblastoma cell lines with these omega-3 fatty acids and observed notable changes. Both EPA and DHA significantly reduced the production of prostaglandin E2, a compound associated with tumor growth and inflammation. Furthermore, we saw that these treatments impaired the viability of medulloblastoma cells, meaning fewer cancer cells were able to survive and grow. Additionally, the treatment led to increased cell death and reduced the ability of these cells to form colonies.
When we moved to the in vivo part of our study, where we implanted human medulloblastoma cells into mice, the results were promising. Mice treated with DHA, with or without EPA, experienced reduced tumor growth. Notably, levels of prostaglandin E and another compound, prostacyclin, dropped significantly in the tumors of treated animals compared to those that did not receive treatment. This suggests that the omega-3 fatty acids helped create a less favorable environment for tumor growth.
Our analysis uncovered that the treatment led to a downregulation of several key genes, with CRYAB being the most significantly affected. We confirmed this finding via various techniques, including immunohistochemistry. This research hints at the potential of combining DHA and EPA in existing treatment plans to target inflammation specific to the tumor environment.

DHA in glioblastoma treatmentPreparation and Evaluation of Mebendazole Microemulsion for Intranasal Delivery: an Alternative Approach for Glioblastoma Treatment.
We investigated the potential of docosahexaenoic acid (DHA) as part of a novel treatment for glioblastoma, a challenging brain tumor. Our study involved formulating mebendazole (MBZ) microemulsions that included DHA along with other compounds, assessing their effectiveness in an orthotopic C6 rat model.
The formulations were carefully characterized before testing. We found that one formulation—composed of oleic acid and labrafil, with a 0.1% mucoadhesive agent—showed promising results. Importantly, there were no observable toxic effects on the nasal epithelium, suggesting the safety of this delivery method.
Furthermore, we observed improved survival rates in the treated rats compared to the control group. Our findings implied that this combined approach with DHA and MBZ microemulsions might offer a new avenue for glioblastoma treatment, although we noted that the contribution of DHA alone couldn't be fully isolated.
Overall, our research encourages the exploration of innovative strategies to enhance the treatment of malignant brain tumors through targeted intranasal delivery.

Omega-3 liposomes reduce tumor viabilityMicrofluidic-derived docosahexaenoic acid liposomes for glioblastoma therapy.
We investigated the potential of docosahexaenoic acid (DHA) liposomes in treating glioblastoma, a challenging type of brain tumor. Using an advanced microfluidic system, we created liposomes that effectively penetrated GBM cells.
The results were promising; the DHA liposomes not only reduced tumor cell viability but also initiated cell death more effectively than regular DHA. This study opens new avenues for cancer treatment using omega-3 fatty acids in liposome formulations, highlighting their potential as a valuable therapeutic strategy.

Omega-3 effects on glioblastoma cellsFABP7 Facilitates Uptake of Docosahexaenoic Acid in Glioblastoma Neural Stem-like Cells.
We explored the potential of omega-3 fatty acid, docosahexaenoic acid (DHA), to combat glioblastoma, an aggressive brain tumor. By studying patient-derived GBM neural stem-like cells, we found that DHA treatment increases its levels in these cells, assisted by a protein called FABP7. This increase in DHA was linked to a reduction in the cells' ability to migrate, suggesting a possible therapeutic approach to limit tumor spread. However, more research is needed to fully understand the implications of DHA on glioblastoma treatment.
