代谢心肌是一种杂食动物,利用各种碳底物来满足其能量需求。虽然成年人的心脏优先消耗脂肪酸(FA)超过碳水化合物,心肌燃料可塑性是生物体生存所必需的。这种控制燃料利用的代谢可塑性处于强大的转录控制之下,过去十年的研究已经阐明了核受体家族因子的成员(例如,过氧化物酶体增殖物激活受体α(PPARα)是心肌脂质代谢的重要调节因子。然而,考虑到健康和疾病中心肌代谢的复杂性,其他分子途径很可能是有效的,对这些途径的阐明可能为新的治疗方法提供基础。我们先前证实Kruppel样因子15(KLF15)是心脏脂质代谢的独立调节因子,因此提高了KLF15和PPARα以协调方式调节脂质氧化所需的心肌基因表达的可能性。在目前的研究中,我们发现KLF15与心肌细胞中典型的PPARα介导的基因表达和脂质氧化的诱导结合,协同作用,并且是所需的。因此,本研究建立了一个涉及KLF15和PPARα的分子模块,并为心脏脂质代谢的分子调控提供了基础性见解。
The metabolic myocardium is an omnivore and utilizes various carbon substrates to meet its energetic demand. While the adult heart preferentially consumes fatty acids (FAs) over carbohydrates, myocardial fuel plasticity is essential for organismal survival. This metabolic plasticity governing fuel utilization is under robust transcriptional control and studies over the past decade have illuminated members of the nuclear receptor family of factors (e.g., PPARα) as important regulators of myocardial lipid metabolism. However, given the complexity of myocardial metabolism in health and disease, it is likely that other molecular pathways are likely operative and elucidation of such pathways may provide the foundation for novel therapeutic approaches. We previously demonstrated that Kruppel-like factor 15 (KLF15) is an independent regulator of cardiac lipid metabolism thus raising the possibility that KLF15 and PPARα operate in a coordinated fashion to regulate myocardial gene expression requisite for lipid oxidation. In the current study, we show that KLF15 binds to, cooperates with, and is required for the induction of canonical PPARα-mediated gene expression and lipid oxidation in cardiomyocytes. As such, this study establishes a molecular module involving KLF15 and PPARα and provides fundamental insights into the molecular regulation of cardiac lipid metabolism.
