摘要: 三甲胺N-氧化物(trimethylamine N-oxide, TMAO)是一种在肝脏中由肝酶氧化三甲胺(trimethylamine,TMA)生成的肠道菌群代谢物。近年来,研究发现血浆TMAO水平在骨质疏松的发生与发展中发挥了重要的作用。本文介绍了TMAO的生理功能和代谢过程,以及它通过氧化应激、炎症等途径对骨质疏松发生与发展所产生的影响。血浆TMAO水平受饮食以及药物等因素的影响,这为骨质疏松的治疗和预防提供了一个新的思路和靶点。

Abstract: Trimethylamine N-oxide (TMAO) is an intestinal flora metabolite produced in the liver by the oxidation of trimethylamine (TMA) by hepatic enzymes. Recently, it has been found that plasma TMAO levels play an important role in the development and progression of osteoporosis. This review has presented the physiological functions and metabolic processes of TMAO, and its effects on the development and progression of osteoporosis through oxidative stress and inflammation. Plasma TMAO levels are influenced by diet as well as medications, which provides a new perspective and target for the treatment and prevention of osteoporosis.

Key words: trimethylamine N-oxide, intestinal flora, osteoporosis, bone mineral density, fracture
