REV-ERB nuclear receptors are potent transcriptional repressors that play an important role in the core mammalian molecular clock and metabolism. Deletion of both REV-ERBα and its largely redundant isoform REV-ERBβ in a murine tissue-specific manner have shed light on their specific functions in clock mechanisms and circadian metabolism. This review highlights recent findings that establish REV-ERBs as crucial circadian timekeepers in a variety of tissues, regulating overlapping and distinct processes that maintain normal physiology and protect from metabolic dysfunction.
REV-ERB 核受体是强有力的转录抑制剂,在哺乳动物核心分子钟和代谢中发挥着重要作用。以鼠组织特异性方式删除 REV-ERBα及其主要冗余同种型 REV-ERBβ,揭示了它们在时钟机制和昼夜代谢中的特定功能。本综述重点介绍了最近的发现,这些发现将 REV-ERB 确立为各种组织中重要的昼夜节律计时者,调节维持正常生理和防止代谢功能障碍的重叠和不同过程。
