雌激素受体相关受体(ERR)α是最早发现的孤儿核受体之一(1988)。许多在ERRα之后发现的孤儿受体被及时地去孤儿化,并被认为是代谢途径的关键转录调节因子。然而,ERRα仍然是一个孤儿。尽管如此,最近的研究已经确定了ERRα的调控机制和转录靶点,允许该受体与其他控制代谢的核受体一起加入行列。值得注意的是,缺乏ERRα的小鼠在受到需要能量代谢“换挡”的压力源(如暴露于寒冷、心脏过载或感染)的挑战时表现出缺陷。这些发现确立了ERRα在适应性能量代谢中的重要性,并提示针对ERRα的策略可能有助于对抗代谢疾病。
Estrogen receptor related receptor (ERR)α was one of the first identified (1988) orphan nuclear receptors. Many of the orphan receptors identified after ERRα were deorphanized in a timely manner and appreciated as key transcriptional regulators of metabolic pathways. ERRα, however, remains an orphan. Nevertheless, recent studies have defined regulatory mechanisms and transcriptional targets of ERRα, allowing this receptor to join ranks with other nuclear receptors that control metabolism. Notably, mice lacking ERRα show defects when challenged with stressors that require a ‘shift of gears’ in energy metabolism, such as exposure to cold, cardiac overload or infection. These findings establish the importance of ERRα for adaptive energy metabolism, and suggest that strategies targeting ERRα may be useful in fighting metabolic diseases.
