摘要S-腺苷蛋氨酸(SAM)是一种存在于人体所有组织和体液中的生理活性分子,参与体内多种重要的生化反应,对调节肝细胞再生、分化以及肝细胞对各种损伤的敏感程度都是非常重要的.SAM对肝脏的这些作用是通过多种途径实现的,现已证实S-腺苷蛋氨酸及其代谢物methyhhioade-nosine(MTA)能阻断脂多糖(LPS)诱导的kupffer细胞中肿瘤坏死因子α(TNF-α)的表达从而对肝脏起到保护作用.S-腺苷蛋氨酸的这些作用可能有益于LPS诱导的肝损伤的临床治疗.

abstractsS-adenosylmethionine(SAM) is a physiologically active molecule in all the organizations and the human body fluids, and it is important to participate in a variety of biochemical reactions, the regulation of liver regeneration, liver cells differentiation and various sensitivity of the injury. The SAM affects the liver through a variety of ways. It is confirmed that the SAM and MTA can block the LPS-induced TNF-α of Kupffer cells to protect the liver. In a word, S-adenosylmethionine may be beneficial to LPS-induced liver in-jury in clinical treatment.
