Type:
DHA (docosahexaenoic acid; 22:6 n-3) is a long-chain omega-3 polyunsaturated fatty acid that functions less like a single “pathway enzyme” and more like a systems-level lipid signaling axis. Most commonly reported directions (context-dependent by dose, formulation, and tumor type):
-↑ Lipid peroxidation → ↑ ferroptosis susceptibility (anti-tumor)
DHA can increase lipid peroxides and promote ferroptotic tumor cell death in some models.
-↓ Proliferation / ↑ apoptosis (anti-tumor tendency)
Reviews summarize inhibition of growth and invasion and pro-apoptotic signaling across multiple cancers (heterogeneous evidence quality; not a universal effect).
Inflammation/eicosanoid “tilt” toward resolution
By shifting lipid mediator balance away from arachidonic-acid–derived pro-inflammatory mediators and toward SPMs, DHA can reduce pro-tumor inflammatory signaling in some contexts.
Big caveat: because DHA can drive oxidative lipid damage, the net effect depends heavily on antioxidant defenses (e.g., GPX4/GSH), iron handling, and whether the tumor is ferroptosis-sensitive.
Effects in Alzheimer’s disease (AD) and neurodegeneration

Mechanistically, DHA is highly relevant to brain biology, but clinical outcomes depend on disease stage:
-Structural/synaptic support (membrane axis)
DHA is a major brain omega-3 and supports membrane properties linked to synaptic function.
-↑ Pro-resolving lipid mediators → microglia modulation / inflammation resolution
SPMs derived from DHA are discussed as supporting a “pro-resolution” microglial phenotype and potentially improving amyloid handling (mechanistic/biomarker-level rationale).
-Clinical signal: more promising earlier (MCI) than established AD A 2023 review notes DHA supplementation shows benefit in some RCTs for mild cognitive impairment (MCI), but no consistent benefit in diagnosed Alzheimer’s disease.
A 2025 meta-analysis in AD similarly concludes omega-3 supplementation does not significantly improve cognition in adults with AD.

3548- ALA,    How Alpha Linolenic Acid May Sustain Blood–Brain Barrier Integrity and Boost Brain Resilience against Alzheimer’s Disease
- Review, AD, NA
*BBB↑, alpha linolenic acid (ALA), the precursor of the majoritarian brain component docosahexaenoic acid (DHA), emerges as a potential novel brain savior, acting via BBB functional improvements,
*other↑, Apolipoprotein E4 (ApoE4) allele carriers are at increased risk to develop AD compared with those carrying the ApoE3 or E2 alleles
*other↑, Our emerging, yet unpublished results, suggest that ALA dietary enrichment in ApoE4 compared with ApoE3 mice brain, restores part of the decreased lipids, and in particular cholesterol and phospholipids, and leads to DHA enrichment in brain blood ve
*DHA↑, We propose that, by conversion to DHA, ALA– the natural substrate in the DHA metabolic pathway– may produce the DHA beneficial effects on BBB and brain health.
*neuroP↑, It has also been shown that DHA confers long-term protection against ischemic brain damage through multiple mechanisms, including suppression of inflammatory responses, decrease in oxidative stress and stimulation of angiogenesis and neurogenesis
*ROS↓,
*other?, while AD pathology follows a long preclinical course, with DHA decrease being a hallmark of brain deterioration with aging [67].
