RESUMO
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.
RESUMO
Sarcopenia is a disease characterized by a decrease in muscle mass and function that can induce adverse events such as falls, weakness, and death. The latest research shows that the use of many hypoglycemic drugs is associated with sarcopenia. Different types of hypoglycemic drugs may have different effects and mechanisms for the quality and function of skeletal muscle. In this paper, we review the research progress of the relationship between hypoglycemic drugs and sarcopenia and the molecular mechanism in recent years to provide a reference for the diagnosis and treatment prevention of sarcopenia in clinical areas.
