随着人们对PPAR在能量代谢各个方面的关键作用的关注,PPAR和PPAR在胎盘发育中的基本功能令人惊讶,在进行遗传分析的过程中经常被认为是一种滋扰。然而,这些发现为研究胎盘生物学提供了一个很好的机会。遗传学和药理学研究,主要是基因敲除动物模型和细胞培养,揭示了PPAR和PPAR、它们的异二聚体RXR伙伴、相关的转录辅助激活因子和靶基因的网络,这些网络调控着胎盘发育和功能的各个方面。这些研究既提供了关于滋养层细胞和胎盘的具体信息,也提供了关于PPAR在其他组织和细胞类型中的功能的潜在线索。它们揭示了PPAR的非凡的多功能性,超越了新陈代谢的协调,扩展到对细胞分化、组织发育和滋养层特定功能的调节。这些信息及其影响是本次审查的主题。
With the major attention to the pivotal roles of PPARs in diverse aspects of energy metabolism, the essential functions of PPAR and PPAR in placental development came as a surprise and were often considered a nuisance en route to their genetic analysis. However, these findings provided an opportune entrée into placental biology. Genetic and pharmacological studies, primarily of knockout animal models and cell culture, uncovered networks of PPAR and PPAR, their heterodimeric RXR partners, associated transcriptional coactivators, and target genes, that regulate various aspects of placental development and function. These studies furnish both specific information about trophoblasts and the placenta and potential hints about the functions of PPARs in other tissues and cell types. They reveal that the remarkable versatility of PPARs extends beyond the orchestration of metabolism to the regulation of cellular differentiation, tissue development, and trophoblast-specific functions. This information and its implications are the subject of this review.
