An excess of fat mass excess predisposes to multiple complications such as type 2 diabetes, cardiovascular diseases or cancer. A dysregulation of lipid metabolism contributes to the development of obesity and the metabolic syndrome. Recent data on lipid mobilization in adipose tissue have revealed a complex pathway involving a human specific hormonal control of lipolysis via the natriuretic peptides and a new triglyceride lipase, ATGL. Activation of fatty acid reesterification and oxidation can lead to an increase in fatty acid utilization. Targeting these key steps of lipid metabolism (adipose tissue lipolysis and fatty acid oxidation) constitutes a potential strategy for the treatment of obesity and associated metabolic disorders.
脂肪量过多易引发多种并发症,如2型糖尿病、心血管疾病或癌症。脂质代谢失调会导致肥胖和代谢综合征的发生。最近有关脂肪组织中脂质动员的数据揭示了一条复杂的途径,该途径涉及通过利钠肽和一种新的甘油三酯脂肪酶(ATGL)对脂解作用进行人类特有的激素控制。脂肪酸再酯化和氧化的激活可导致脂肪酸利用率的提高。针对脂质代谢的这些关键步骤(脂肪组织脂解和脂肪酸氧化)构成了治疗肥胖及相关代谢紊乱的潜在策略。
