过氧化物酶体增殖物激活受体 (PPAR) 是核受体超家族的成员,在全身能量代谢中发挥着重要作用。 PPAR 分为三种亚型,即 PPARα、β/δ 和 γ。它们共同参与全身的脂肪酸氧化以及葡萄糖和脂质代谢。重要的是,PPAR 的三种异构体在细胞和全身水平的能量平衡方面具有互补且不同的代谢活性。 PPAR 还与其他共同调节器一起维持能量稳态。当内源配体与这些受体结合时,它们调节参与能量稳态的基因的转录。然而,PPARs在能量代谢中的确切分子机制仍不清楚。在这篇综述中,我们总结了 PPAR 信号在多个器官中的重要性,并重点关注 PPAR 信号在细胞和全身能量稳态中的关键作用。
Peroxisome proliferator-activated receptors (PPARs), members of the nuclear receptor superfamily, are important in whole-body energy metabolism. PPARs are classified into three isoforms, namely, PPARα, β/δ, and γ. They are collectively involved in fatty acid oxidation, as well as glucose and lipid metabolism throughout the body. Importantly, the three isoforms of PPARs have complementary and distinct metabolic activities for energy balance at a cellular and whole-body level. PPARs also act with other co-regulators to maintain energy homeostasis. When endogenous ligands bind with these receptors, they regulate the transcription of genes involved in energy homeostasis. However, the exact molecular mechanism of PPARs in energy metabolism remains unclear. In this review, we summarize the importance of PPAR signals in multiple organs and focus on the pivotal roles of PPAR signals in cellular and whole-body energy homeostasis.
