Full textThe capacité of HDL to protect LDL against oxidative stress is well established. However, mechanisms involved in such activity remain undetermined. Our firts aim was to assess the relationship between physicochemical properties of sub-fractions of LDL and their antiatherogenic in particular antioxidative (AOX) activities. We have demonstrated that HDL3 is depleted in spingomyelin and enriched in spingosine-1-phosphate as compared to HDL2. In addition, HDL3 displayed an elevated ratio of apolipoprotein AI (apoAI) to apoAII, and increased activities of HDL-associated enzymes with AOX properties. We have also studied mechanisms involved in the AOX activity of HDL Our data suggest a two-step mechanism involving transfer of phospholipids hydroperoxides (PLOOH) from oxidized LDL to HDL ; this step is influenced by the fluidity of the PL monolayer de HDL, and the reduction of PLOOH to redox-inactive PLOH largely through the action of two methionine residues of apoAI. This study emphasizes the importance of HDL in mitigating potential atherogenecity of LDL

Full textLinoleic (LA) and α-linolenic (ALA) acids are two polyunsaturated fatty acids. They are essential for humans because we are unable to synthesize them in situ. These two fatty acids are the representatives of omega-6 (LA) and omega-3 (ALA). Although they are essential and therefore necessary, the issue of the omega-6 / omega-3 ratio between these two families is also important to take into account in the diet. The consumption habits of the French over the past thirty years have shifted the balance against omega-3s compared to omega-6s. Or a rebalancing of the omega-6 / omega-3 balance tends to reduce cardiovascular risks. Linseed and camelina oils are endemic crops in France extremely rich in ALA. They are the most suitable for supplementation with omega-3 of plant origin. However, the high contents of polyunsaturated fatty acids in these oils are responsible for their low oxidative stabilities. The consumption of oxidized oils or fats is not recommended because they can contribute toxic molecules. The aim of this project was to improve the shelf life of oils rich in polyunsaturated fatty acids by enhancing the antioxidant extracts of the cakes obtained after crushing the seeds. Among the molecules studied, gallic acid, caffeic acid, propyl gallate as well as pinoresinol and lariciresinol purified from flax showed a real interest in slowing down oxidation, while secoisolariciresinol was ineffective
