已知活性醛的非酶促自由基生成会导致持续氧化应激疾病,包括类风湿性关节炎、动脉粥样硬化、神经退行性疾病和许多肝脏疾病。与此同时,脂质亲电子试剂的积累已被证明通过修饰对细胞稳态至关重要的蛋白质在细胞信号转导事件中发挥作用。鉴于反应性谱的广泛范围以及修改众多蛋白质组和基因组过程的能力,新的重点正在放在对亲电加合后果的基于系统的分析上。本综述重点关注脂质衍生醛的生成和化学反应性,特别关注对亲电应激的稳态反应。
The non-enzymatic free radical generation of reactive aldehydes is known to contribute to diseases of sustained oxidative stress including rheumatoid arthritis, atherosclerosis, neurodegenerative and a number of liver diseases. At the same time, the accumulation of lipid electrophiles has been demonstrated to play a role in cell signaling events through modification of proteins critical for cellular homeostasis. Given the broad scope of reactivity profiles and the ability to modify numerous proteomic and genomic processes, new emphasis is being placed on a systems-based analysis of the consequences of electrophilic adduction. This review focuses on the generation and chemical reactivity of lipid-derived aldehydes with a special focus on the homeostatic responses to electrophilic stress.
