过氧化物酶体激活受体α(过氧化物酶体激活受体α)是一种在代谢调节中起主要作用的转录因子。本文综述了PPARα在中间代谢中的功能作用,并详细概述了PPARα靶向的代谢基因,重点是肝脏。对PPARα对代谢的影响在生理学、药理学和营养活化方面进行了区分。低通量和高通量基因表达分析已经允许创建一个综合图谱,说明PPARα通过调节许多基因作为脂质代谢的主要调节因子的作用。该图谱将PPARα置于影响脂肪酸摄取、脂肪酸活化、细胞内脂肪酸结合、线粒体和过氧化物酶体脂肪酸氧化、生酮、甘油三酯周转、脂滴生物学、脂质体生成和胆汁合成/分泌的调节中心。此外,PPARα控制几种发挥局部和内分泌功能的分泌蛋白的表达。
The Peroxisome Proliferator Activated Receptor alpha (PPARα) is a transcription factor that plays a major role in metabolic regulation. This review addresses the functional role of PPARα in intermediary metabolism and provides a detailed overview of metabolic genes targeted by PPARα, with a focus on liver. A distinction is made between the impact of PPARα on metabolism upon physiological, pharmacological, and nutritional activation. Low and high throughput gene expression analyses have allowed the creation of a comprehensive map illustrating the role of PPARα as master regulator of lipid metabolism via regulation of numerous genes. The map puts PPARα at the center of a regulatory hub impacting fatty acid uptake, fatty acid activation, intracellular fatty acid binding, mitochondrial and peroxisomal fatty acid oxidation, ketogenesis, triglyceride turnover, lipid droplet biology, gluconeogenesis, and bile synthesis/secretion. In addition, PPARα governs the expression of several secreted proteins that exert local and endocrine functions.
