Comparative anti-inflammatory effects of plant- and marine-derived omega-3 fatty acids explored in an endothelial cell line
Comparative anti-inflammatory effects of plant- and marine-derived omega-3 fatty acids explored in an endothelial cell line
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) lower risk of cardiovascular disease. The primary source of EPA and DHA is fatty fish. Plant-derived alpha linolenic acid (ALA) and stearidonic acid (SDA) could provide sustainable land-based alternatives, but their functionality is underexplored. Omega-3 fatty acids (n-3 FAs) may influence atherogenic processes through changing endothelial cell (EC) function and lowering inflammation. This study compared effects of marine- and plant-derived n-3 FAs on EC inflammatory responses. EA.hy926 cells were exposed to ALA, SDA, EPA or DHA prior to stimulation with tumor necrosis factor (TNF)-α. All FAs were shown to be incorporated into ECs in a dose-dependent manner. SDA (50 μM) decreased both production and cell-surface expression of intercellular adhesion molecule (ICAM)-1; however EPA and DHA resulted in greater reduction of ICAM-1 production and expression. EPA and DHA also significantly lowered production of monocyte chemoattractant protein 1, interleukin (IL)-6 and IL-8. ALA, SDA and DHA (50 μM) all reduced adhesion of THP-1 monocytes to EA.hy926 cells. DHA significantly decreased nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB)p105 gene expression and phosphorylated NFκBp65 protein. Both EPA and DHA (50 μM) significantly decreased cyclooxygenase (COX)-2 protein. Thus, both marine-derived n-3 FAs, particularly DHA, had potent anti-inflammatory effects in this EC model. Of the plant-derived n-3 FAs, SDA showed the greatest inhibition of inflammation. Although neither ALA nor SDA reproduced the anti-inflammatory effects of EPA and DHA in this model, there is some potential for SDA to be a sustainable anti-inflammatory alternative to the marine n-3 FAs.

Abstract
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) lower risk of cardiovascular disease. The primary source of EPA and DHA is fatty fish. Plant-derived alpha linolenic acid (ALA) and stearidonic acid (SDA) could provide sustainable land-based alternatives, but their functionality is underexplored. Omega-3 fatty acids (n-3 FAs) may influence atherogenic processes through changing endothelial cell (EC) function and lowering inflammation. This study compared effects of marine- and plant-derived n-3 FAs on EC inflammatory responses. EA.hy926 cells were exposed to ALA, SDA, EPA or DHA prior to stimulation with tumor necrosis factor (TNF)-α. All FAs were shown to be incorporated into ECs in a dose-dependent manner. SDA (50 μM) decreased both production and cell-surface expression of intercellular adhesion molecule (ICAM)-1; however EPA and DHA resulted in greater reduction of ICAM-1 production and expression. EPA and DHA also significantly lowered production of monocyte chemoattractant protein 1, interleukin (IL)-6 and IL-8. ALA, SDA and DHA (50 μM) all reduced adhesion of THP-1 monocytes to EA.hy926 cells. DHA significantly decreased nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB)p105 gene expression and phosphorylated NFκBp65 protein. Both EPA and DHA (50 μM) significantly decreased cyclooxygenase (COX)-2 protein. Thus, both marine-derived n-3 FAs, particularly DHA, had potent anti-inflammatory effects in this EC model. Of the plant-derived n-3 FAs, SDA showed the greatest inhibition of inflammation. Although neither ALA nor SDA reproduced the anti-inflammatory effects of EPA and DHA in this model, there is some potential for SDA to be a sustainable anti-inflammatory alternative to the marine n-3 FAs.
