体温的昼夜节律振荡是哺乳动物生物学中一个基本的、进化上保守的特征。此外,内稳态通路使生物体能够在寒冷暴露时保护其核心温度。然而,负责协调每日体温节律以及对环境挑战的适应性的机制尚不清楚。在此我们表明,核受体Rev - erbα,一种强大的转录抑制因子,通过调节棕色脂肪组织(BAT)功能将昼夜节律和产热网络联系起来。在Rev - erbα几乎不表达的早上5点(授时因子时间22),暴露于寒冷环境的小鼠比在Rev - erbα大量存在的下午5点(ZT10)表现要好得多。Rev - erbα的缺失显著提高了下午5点时的耐寒能力,这表明克服Rev - erbα依赖性抑制是对寒冷产热反应的一个基本特征。寒冷温度对解偶联蛋白1(UCP1)的生理诱导之前,棕色脂肪组织中Rev - erbα会快速下调。Rev - erbα以棕色脂肪细胞自主的方式抑制UCP1,并且即使在热中性条件下,Rev - erbα缺失小鼠的棕色脂肪组织UCP1水平也很高。Rev - erbα的基因缺失也消除了体温和棕色脂肪组织活动的正常节律。因此,Rev - erbα作为一个产热焦点,以一种能适应环境需求的方式建立和维持体温节律。
Circadian oscillation of body temperature is a basic, evolutionary-conserved feature of mammalian biology. Additionally, homeostatic pathways allow organisms to protect their core temperatures in response to cold exposure. However, the mechanism responsible for coordinating daily body temperature rhythm and adaptability to environmental challenges is unknown. Here we show that the nuclear receptor Rev-erbα, a powerful transcriptional repressor, links circadian and thermogenic networks through the regulation of brown adipose tissue (BAT) function. Mice exposed to cold fare dramatically better at 5 AM (Zeitgeber time 22) when Rev-erbα is barely expressed than at 5 PM (ZT10) when Rev-erbα is abundant. Deletion of Rev-erbα markedly improves cold tolerance at 5 PM, indicating that overcoming Rev-erbα-dependent repression is a fundamental feature of the thermogenic response to cold. Physiological induction of uncoupling protein 1 (UCP1) by cold temperatures is preceded by rapid down-regulation of Rev-erbα in BAT. Rev-erbα represses UCP1 in a brown adipose cell-autonomous manner and BAT UCP1 levels are high in Rev-erbα-null mice even at thermoneutrality. Genetic loss of Rev-erbα also abolishes normal rhythms of body temperature and BAT activity. Thus, Rev-erbα acts as a thermogenic focal point required for establishing and maintaining body temperature rhythm in a manner that is adaptable to environmental demands.
