  • Background: Aortic valve stenosis (AVS), which is the most common valvular heart disease, causes a progressive narrowing of the aortic valve as a consequence of thickening and calcification of the aortic valve leaflets. The beneficial effects of omega-3 polyunsaturated fatty acids (n-3 PUFA) in cardiovascular prevention have been recently demonstrated in a large randomized controlled trial. In addition, n-3 PUFA serve as the substrate for the synthesis of specialized pro-resolving mediators (SPMs), which are known by their potent beneficial anti-inflammatory, pro-resolving and tissue-modifying properties in cardiovascular disease. However, the effects of n-3 PUFA and SPMs on AVS have not yet been determined. The aim of this study was to identify the role of n-3 PUFA-derived SPMs in relation to the development of AVS. Methods: Lipidomic and transcriptomic analyses were performed in human tricuspid aortic valves. Apoe-/- mice and wire injury in C57BL/6J mice were used as models for mechanistic studies. Results: We found that n-3 PUFA incorporation into human stenotic aortic valves was higher in non-calcified regions compared with calcified regions. LC-MS-MS based lipid mediator lipidomics identified that the n-3 PUFA-derived SPM resolvin E1 (RvE1) was dysregulated in calcified regions and acted as a calcification inhibitor. Apoe-/- mice expressing the Caenorhabditis elegans Fat-1 transgene (Fat-1tgxApoe-/-), which enables the endogenous synthesis of n-3 PUFA, increased valvular n-3 PUFA content, exhibited reduced valve calcification, lower aortic valve leaflet area, increased M2 macrophage polarization and improved echocardiographic parameters. Finally, abrogation of the RvE1 receptor ChemR23 enhanced disease progression, and the beneficial effects of Fat-1tg were abolished in the absence of ChemR23. Conclusions: n-3 PUFA-derived RvE1 and its receptor ChemR23 emerge as a key axis in the inhibition of AVS progression, and may represent a novel potential therapeutic opportunity to be evaluated in patients with AVS.
