Abstract

Cardiovascular disease is a leading cause of mortality among patients with diabetes, and heart failure exists even in the absence of coronary disease. Myocardial metabolism is altered in the diabetic heart as a result of changes in substrate availability secondary to insulin resistance. The nuclear receptor peroxisome proliferator activated receptor-alpha (PPARα) and PPAR-gamma coactivator-1alpha (PGC-1α) play important roles in transcriptional regulation of myocardial metabolism and contribute significantly to the changes that occur in the diabetic heart. This review summarizes the role of PPARα and PGC-1α in myocardial metabolism in the normal heart and in the diabetic heart.

摘要

心血管疾病是糖尿病患者死亡的主要原因,即使在没有冠心病的情况下也会出现心力衰竭。由于胰岛素抵抗导致底物可用性改变,糖尿病心脏中的心肌代谢发生改变。核受体过氧化物酶体增殖物激活受体α(PPARα)和PPARγ共激活因子-1α(PGC-1α)在心肌代谢的转录调节中起重要作用,并对糖尿病心脏中发生的变化有显著影响。本文综述了PPARα和PGC-1α在正常心脏和糖尿病心脏心肌代谢中的作用。
