项目摘要
Long chain fatty acids are incorporated into chylomicrons and transported trough lymph, whereas medium chain fatty acids which are transported in the portal blood directly to the liver and are consumed as energy immediately. However, the role of medium chain fatty acids on energy expenditure in skeletal muscle was unclear. In the present study, we found that the expression of uncoupling protein 3(UCP3) and pyruvate dehydrogenase kinase 4(PDK4) was increased in medium chain fatty acid-treated muscle cells. The uptake of medium chain fatty acids in FATP1-transfected cells significantly increased, compared with that in mock-transfected cells. Furthermore, the expression of UCP3 induced by medium chain fatty acid was blocked with GSK0660, a selective PPAR-δantagonist, in muscle cells. These findings suggest that medium chain fatty acids protect the obesity by a mechanism that may involve in the expression of UCP3 in skeletal muscle, resulting in increased thermoregulation.
长链脂肪酸被掺入乳糜微粒和转运的淋巴结中,而中型链脂肪酸直接在门户血液中转运到肝脏,并立即以能量消耗。然而,中链脂肪酸在骨骼肌中能量消耗中的作用尚不清楚。在本研究中,我们发现在中链脂肪酸处理的肌肉细胞中增加了解耦蛋白3(UCP3)和丙酮酸脱氢酶激酶4(PDK4)的表达。与模拟转染的细胞相比,FATP1转染细胞中中链脂肪酸的摄取显着增加。此外,在肌肉细胞中,由中链脂肪酸诱导的UCP3的表达被选择性PPAR-Δantagonist封闭。这些发现表明,中链脂肪酸通过一种可能涉及骨骼肌中UCP3表达的机制来保护肥胖,从而导致体温调节增加。
