Abstract:
According to current research, cancer cell growth is suppressed by ω-3 fatty acids, which are essential fatty acids. On the other hand, ω-3 fatty acids are metabolized to bioactivities in vivo. A systematic evaluation of the ability of ω-3 fatty acids and their metabolites to suppress cancer cell growth has not been sufficiently conducted. Our work evaluated the effect of ω-3 fatty acids (docosahexaenoic acid, eicosapentaenoic acid), trans fatty acid, and the metabolites (Resolvin E1, Maresin 1) on cancer cell growth suppressibility. Our results suggest that there may be optimal fatty acids depending on the kind of cancer cells, the presence or absence of hydroxyl group, and the double bond structure involved.
Insights
Omega-3 fatty acids and their metabolites show potential in suppressing cancer cell growth. Optimal fatty acid selection may depend on cancer type and molecular structure for targeted therapy.
Area of Science:
- Biochemistry
- Oncology
- Nutritional Science
Background:
- Omega-3 fatty acids are known to inhibit cancer cell proliferation.
- In vivo metabolism of omega-3 fatty acids yields bioactive compounds.
- A comprehensive evaluation of these compounds' anti-cancer effects is lacking.
Purpose of the Study:
- To systematically assess the cancer cell growth suppressive capabilities of omega-3 fatty acids and their metabolites.
- To investigate the influence of specific fatty acid structures (e.g., hydroxyl groups, double bonds) on anti-cancer activity.
Main Methods:
- Evaluation of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
- Assessment of trans fatty acids.
- Analysis of metabolites: Resolvin E1 and Maresin 1.
- Testing on various cancer cell lines to determine growth suppressibility.
Main Results:
- Both omega-3 fatty acids and their metabolites demonstrated varying degrees of cancer cell growth suppression.
- The efficacy of fatty acids was dependent on the specific cancer cell type.
- Structural features, including the presence of hydroxyl groups and double bond configuration, influenced suppressive activity.
Conclusions:
- Omega-3 fatty acids and their metabolites possess anti-cancer properties.
- Tailoring fatty acid interventions based on cancer type and molecular characteristics is crucial for efficacy.
- Further research into specific fatty acid structures could lead to novel cancer therapies.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
