DHA shows promise against neuroblastomaUltra-High Dose Oral ω3 Eicosapentaenoic Acid (EPA), Docosahexaenoic Acid (DHA), or Oxidation-Resistant Deuterated DHA Block Tumorigenesis in a -Driven Neuroblastoma Model.
Strong relevance to DHA's effects
We conducted a study to explore the effects of docosahexaenoic acid (DHA) on tumor formation, particularly in a mouse model of neuroblastoma—a type of aggressive cancer in children. By using a syngeneic model, we gavaged wildtype mice with high doses of omega-3 fatty acids, including DHA, and then injected cancerous cells to monitor tumor development.
In our experiment, we noticed that while 50% of untreated control mice developed tumors, those receiving high doses of DHA or its oxidation-resistant form completely avoided tumor formation. This was quite striking and contrasts with our findings regarding arachidonic acid (ARA), which actually seemed to enhance tumor growth. Notably, when we combined ARA with EPA (another fatty acid), it led to a lower tumor burden, suggesting that DHA acts through a different, non-oxidative mechanism.
These results suggest that high-dose DHA may offer a promising, low-toxicity therapy option for neuroblastoma, paving the way for safer future treatments. It’s exciting to see the potential of omega-3 fatty acids in cancer prevention, especially given their safety and tolerability in humans over extended periods.

Omega-3 fatty acids inhibit tumorsUltra-High Dose Oral ω3 Eicosapentaenoic Acid (EPA), Docosahexaenoic Acid (DHA), or Oxidation-Resistant Deuterated DHA Block Tumorigenesis in a -Driven Neuroblastoma Model.
Strong link to cancer treatment
We conducted a study to explore the effects of high doses of omega-3 fatty acids—specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—on tumor formation in a model of neuroblastoma, a challenging pediatric cancer. Using a syngeneic mouse model, we administered these fatty acids at doses equivalent to those safely tolerable in humans.
After the gavage, we introduced neuro-2a cells that were prone to tumor development. Our observations revealed that both DHA and EPA completely halted tumor formation in the treated mice, in stark contrast to the control group where half of the mice did develop tumors. Intriguingly, we also noticed that arachidonic acid (another fatty acid) actually promoted tumor growth, suggesting that it might counteract the positive effects of EPA.
Overall, these findings indicate that ultra-high doses of omega-3 fatty acids, particularly DHA and EPA, could offer a promising, low-toxicity treatment for neuroblastoma by blocking tumorigenesis. This research highlights the potential for incorporating dietary fatty acids into cancer therapies, especially for high-risk pediatric patients who currently face limited options.

DHA affects colorectal cancer pathwaysDietary polyunsaturated fatty acids affect PPARγ promoter methylation status and regulate the PPARγ/COX2 pathway in some colorectal cancer cell lines.
Study focuses on DHA's effects
We set out to explore how docosahexaenoic acid (DHA), a type of omega-3 fatty acid, affects colorectal cancer (CRC) cells. In this study, we treated five different colorectal cancer cell lines with varying concentrations of DHA, along with other fatty acids like eicosapentaenoic acid (EPA) and linoleic acid (LA). This allowed us to see if DHA could impact the methylation patterns of the PPARγ promoter, a key player in cancer regulation, and affect the relationship between PPARγ and COX2, two important molecules involved in cancer growth.
Our findings revealed that DHA significantly altered the methylation status in some cell lines, effectively demethylating specific regions of the PPARγ promoter. We observed that this demethylation was linked to an increase in the expression of PPARγ in cells where it was hemimethylated. Interestingly, DHA not only boosted PPARγ levels but also downregulated COX2 across all CRC cell lines tested. This suggests that DHA might have a role in reducing inflammatory signals linked to cancer progression.
The overall impact seemed to vary depending on the type of cancer cell we were working with, indicating a cell type-dependent effect of DHA. Notably, we found that DHA was more effective than EPA or LA in modulating the PPARγ promoter. This research shows promising potential for DHA in colorectal cancer treatment and highlights its importance in dietary considerations for cancer management.

DHA shows promise in cancer therapyAPT imaging of hepatocellular carcinoma signals an effective therapeutic response in advance of tumor shrinkage.
Nanoparticle delivery context acknowledged
We assessed the effectiveness of docosahexaenoic acid (DHA) in treating cancer, specifically in various rodent models of hepatocellular carcinoma (HCC). The study utilized weighted amide proton transfer (APT) MRI to monitor tumor response in three different HCC models: diethylnitrosamine (DEN) induced HCC, N1S1 syngeneic orthotopic xenograft, and human HepG2 ectopic xenograft.
Our findings revealed that all HCC models exhibited a markedly higher APT signal compared to surrounding normal tissues. This increased signal allowed us to distinguish between malignant HCC lesions and benign nodules specifically in the DEN model.
By administering low-density lipoprotein docosahexaenoic acid (LDL-DHA) nanoparticles directly to N1S1 xenografts, we observed a significant reduction in tumor APT signal within just 72 hours. Similarly, direct injections into HepG2 xenografts demonstrated comparable therapeutic effects. Overall, this study showcases the potential of APT imaging in the diagnostic and therapeutic management of HCC, particularly highlighting DHA's effectiveness delivered via nanoparticles.

In our research, we looked into the potential benefits of docosahexaenoic acid, a type of omega-3 fatty acid, in treating pancreatic cancer. Utilizing a mouse model that closely mirrors the human disease, we examined how a diet rich in omega-3 fatty acids—specifically eicosapentaenoic acid and docosahexaenoic acid—affects tumor growth and metastasis.
We observed that mice on a diet supplemented with cod liver oil, which is high in omega-3s, exhibited a notable decrease in tumor size and lung and liver metastasis compared to control mice. The treatment seemed to enhance survival rates, suggesting that these fatty acids may help combat the growth of cancerous tumors.
Moreover, our findings indicated changes in the tumor's fatty acid profile and the release of eicosanoids, which are important signaling molecules in cancer. The intervention also reduced key histological features of malignancy and promoted apoptosis, or programmed cell death, without impacting the rate of cell proliferation. This indicates that omega-3 fatty acids might act in ways other than just slowing down cell division.
We noted a significant reduction in tumor fibrosis, which is often associated with aggressive cancer forms. This was linked to lower levels of Sonic Hedgehog, a protein playing a central role in tumor development. Overall, our study highlights the promise of docosahexaenoic acid and its fellow omega-3 fatty acids as potential dietary tools in pancreatic cancer treatment, paving the way for incorporating nutritional strategies into cancer care.

Docosahexaenoic acid is a vital omega-3 fatty acid for health. Consuming at least 250 mg of DHA daily may lower the risk of cancer. I purchased this for my mother to support her brain function.
I took this to my mother, a cancer patient. I've read much praise for it concerning those on the keto diet. The packaging is large, and the fish monk is easy for her to swallow, suiting her dietary needs. The ingredients are excellent for a cancer patient, and my mother began today. The quality of this product is also highly esteemed. My mother is 72; I pray for her healing.

I love this product! DHA is crucial for skin and eye health. Supplementing with DHA can improve children's vision and brain development, reducing future risks of issues like learning difficulties and ADHD. In older age, DHA may enhance brain function and lower Alzheimer's risk. It can also reduce the chances of cardiovascular disease and inflammation, helping in cancer prevention. Please support my review; I would be grateful.
