We explored an innovative approach to treating glioblastoma, the most common malignant brain tumor, by utilizing docosahexaenoic acid (DHA) liposomes. These liposomes were created using a microfluidic system that allowed for fine-tuning various properties, which could enhance their effectiveness in targeting tumor cells.
Our findings revealed that these DHA liposomes, ranging in size from 80 nm to 130 nm, were successfully taken up by glioblastoma cells. This uptake was promising, as we saw a reduction in the viability of these cancerous cells. Interestingly, we also observed that DHA liposomes were significantly better at triggering cell death mechanisms compared to free DHA, specifically through pathways that involved caspase-3.
Overall, our study suggests that these microfluidic-derived DHA liposomes might offer new avenues for developing therapies using omega-3 fatty acids against brain tumors, potentially leading to more effective treatment options in the future.

DHA inhibits glioblastoma cell migration
FABP7 Facilitates Uptake of Docosahexaenoic Acid in Glioblastoma Neural Stem-like Cells.
We investigated how docosahexaenoic acid (DHA) impacts glioblastoma, a type of aggressive brain tumor notorious for its poor outcomes. The focus was on neural stem-like cells within these tumors, as they are known to contribute to drug resistance and promote the heterogeneity of the tumor.
Our research involved examining patient-derived glioblastoma neural stem-like cells grown in neurosphere cultures. We wanted to see how treatments with levels of DHA and arachidonic acid (AA) would affect the fatty acid profiles of these cells. Notably, we discovered that DHA treatment increased both the levels of DHA and the ratio of DHA to AA in these cells, with the assistance of brain fatty acid-binding protein (FABP7) which plays a crucial role in facilitating the uptake of DHA.
An interesting finding was that as the cells absorbed more DHA, their ability to migrate diminished. This could signal a potential therapeutic avenue where increasing DHA in glioblastoma could restrain the aggressive behavior of these neural stem-like cells, potentially leading to better outcomes for patients.
More research will be essential to fully understand the implications of this increased DHA content in the tumor microenvironment and its overall effects on the progression of glioblastoma.

DHA liposomes target glioblastoma effectively
Microfluidic-Derived Docosahexaenoic Acid Liposomes for Targeting Glioblastoma and Its Inflammatory Microenvironment.
We investigated the role of docosahexaenoic acid (DHA) in targeting glioblastoma, a challenging brain tumor with limited treatment options. By utilizing a special technique to create DHA liposomes, we aimed to reduce the inflammatory environment surrounding the tumor. This innovative approach allowed for a targeted delivery of DHA to the affected areas.
Through our research, we observed that these DHA liposomes were quickly taken up by macrophages, a type of immune cell, without causing any harm to them. We also discovered that these liposomes significantly lowered the activity of genes associated with inflammation and decreased the release of key inflammatory cytokines in both stimulated macrophages and glioblastoma cells.
Interestingly, while the DHA liposomes showed effectiveness in regulating inflammation, they did not notably change the expression of a certain anti-inflammatory gene in macrophages. Furthermore, our findings indicated that using DHA in liposome form was more effective than administering it freely.
Overall, our study highlights a promising strategy for using DHA liposomes to target glioblastoma and its inflammatory microenvironment. This innovative approach could lead to new treatment options for patients facing this aggressive type of brain cancer.

We examined the effects of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)—two types of omega-3 fatty acids—on medulloblastoma (MB), a common and aggressive brain tumor in children. Our study involved treating MB cell lines with these fatty acids and also used a mouse model to assess their effects in a living organism. We randomized mice with implanted MB cells into three groups: one receiving DHA, one receiving a combination of DHA and EPA, and a control group.
Through our experiments, we found that DHA and EPA could significantly reduce the secretion of prostaglandin E2, a compound that can promote tumor growth. In doses that we tested, these omega-3 fatty acids impaired the viability and colony formation abilities of MB cells while also increasing cell death. Additionally, we observed that DHA treatment led to reduced tumor size in mice, and we noticed a decrease in inflammatory markers like prostacyclin in treated tumors compared to those in control mice.
Further analysis through RNA sequencing highlighted 10 genes that were commonly downregulated in tumors treated with omega-3 fatty acids. Among them, CRYAB stood out as the most significantly altered gene, a finding we confirmed through immunohistochemistry. This suggests a protective role of these fatty acids in targeting inflammatory responses in the tumor microenvironment, potentially offering a new avenue for medulloblastoma treatment in conjunction with standard therapies.

DHA impacts glioblastoma behavior
Super resolution microscopy reveals DHA-dependent alterations in glioblastoma membrane remodelling and cell migration.
We explored the impact of docosahexaenoic acid (DHA), a type of omega-3 fatty acid, on brain tumors, particularly glioblastoma (GBM). Our investigation focused on how DHA influences cell migration and the structural changes in cell membranes.
By using advanced imaging techniques, we observed that DHA alters the behavior of proteins that assist in cell movement. Specifically, we noted that when GBM cells were treated with DHA, the formation of specific membrane structures associated with cell migration was disrupted, suggesting that DHA could slow down tumor spreading.
We also discovered that higher levels of a protein called FABP7 were linked to more rigid cell membranes, which could facilitate movement. However, when DHA was present, these rigid structures softened, which was associated with decreased movement of the tumor cells. This creates a fascinating connection between dietary fatty acids and tumor behavior.
Overall, our findings indicate that DHA could play a critical role in reducing the aggressive nature of glioblastoma by changing how tumor cells move and interact with their environment. This supports the idea that dietary influences can be significant in cancer treatment strategies.

DHA induces autophagy in GBM
SQSTM1/p62 is involved in docosahexaenoic acid-induced cellular autophagy in glioblastoma cell lines.
We investigated how docosahexaenoic acid (DHA), a key omega-3 fatty acid found in the human brain, impacts glioblastoma multiforme (GBM) cells. Our findings revealed that high doses of DHA can indeed induce a process known as cellular autophagy in two specific GBM cell lines, U251 and U118, while lower doses did not show the same effect.
We observed that after treating the U251 cells with a high dose of DHA across various time intervals (12, 24, and 48 hours), the levels of a protein called SQSTM1/p62 exhibited an interesting pattern. Initially, the protein levels decreased at 12 and 24 hours, but increased again by 48 hours. In U118 cells, however, SQSTM1/p62 levels rose consistently at all measured time points.
Furthermore, we discovered that the mRNA levels of SQSTM1/p62 increased in both cell lines following DHA treatment. This indicates that DHA encourages the production of SQSTM1/p62. Notably, when we reduced the levels of SQSTM1/p62 using a designated siRNA, the autophagy triggered by DHA was lessened in both cell lines. This led us to conclude that SQSTM1/p62 plays a significant regulatory role in the DHA-induced autophagic process.
Overall, high-dose DHA was shown to effectively promote autophagy in glioblastoma cells. However, the broader implications for tumor reduction are still unclear and warrant further clinical investigation.
