    • Provided is an age-related apolipoprotein B oxidase (apoBNOX) found tightly associated with the low-density lipoprotein particles and believed to be responsible for oxidizing lipoprotein particles and initiating atherogenesis. It causes damage by directly oxidizing the apolipoprotein B protein and indirectly oxidizing the lipids in the particles due to superoxide formation by the apoBNOX and its conversion into hydrogen peroxide. apoBNOX activity is inhibited by tyrosol and hydroxytyrosol and components of white wine, important components of French and Mediterranean diets, which seem to be a very good source of inhibitors of the apolipoprotein B oxidase. Agents comprising at least one naturally-occurring apoBNOX inhibitor and compositions lessen, ameliorate or treat disorders and complications resulting from cell damage caused by oxidation of apolipoprotein B. Also provided is an assay system comprising recombinant apoBNOX or an equivalent peptide and apolipoprotein B purified from human sera as a model to screen for agents and supplements that lower apoBNOX activity when administered orally.
    • 提供与年龄相关的载脂蛋白B氧化酶(apoBNOX),其发现与低密度脂蛋白颗粒紧密相关,并被认为负责氧化脂蛋白颗粒并引发动脉粥样化形成。 它通过直接氧化载脂蛋白B蛋白并间接氧化颗粒中的脂质而引起损伤,这是由于apoBNOX的超氧化物形成及其转化为过氧化氢。 apoBNOX活性被酪醇和羟基酪醇以及白葡萄酒的成分,法国和地中海饮食的重要组成部分所抑制,这似乎是载脂蛋白B氧化酶抑制剂的非常好的来源。 包含至少一种天然存在的apoBNOX抑制剂的药剂和减轻,改善或治疗由载脂蛋白B氧化引起的细胞损伤引起的疾病和并发症的组合物。还提供了包含重组apoBNOX或从人体纯化的等效肽和载脂蛋白B的测定系统 血清作为模型,用于筛选当口服给药时降低apoBNOX活性的药剂和补充剂。
