Sleep deprivation (SD) has negative effects on brain and body function. Sleep problems are prevalent in a variety of disorders, including neurodevelopmental and psychiatric conditions. Thus, understanding the molecular consequences of SD is of fundamental importance in biology. In this study, we present the first simultaneous bulk and single-nuclear RNA sequencing characterization of the effects of SD in the male mouse frontal cortex. We show that SD predominantly affects glutamatergic neurons, specifically in layers 4 and 5, and produces isoform switching of over 1500 genes, particularly those involved in splicing and RNA binding. At both the global and cell-type specific level, SD has a large repressive effect on transcription, downregulating thousands of genes and transcripts. As a resource we provide extensive characterizations of cell-types, genes, transcripts, and pathways affected by SD. We also provide publicly available tutorials aimed at allowing readers adapt analyses performed in this study to their own datasets.
睡眠剥夺(SD)对大脑和身体功能有负面影响。睡眠问题在包括神经发育和精神疾病在内的多种疾病中普遍存在。因此,了解睡眠剥夺的分子后果在生物学中至关重要。在本研究中,我们首次对雄性小鼠额叶皮质中睡眠剥夺的影响进行了同时的批量和单核RNA测序表征。我们表明,睡眠剥夺主要影响谷氨酸能神经元,特别是在第4层和第5层,并导致超过1500个基因的异构体转换,尤其是那些参与剪接和RNA结合的基因。在整体和细胞类型特异性水平上,睡眠剥夺对转录具有很大的抑制作用,下调数千个基因和转录本。作为一种资源,我们提供了受睡眠剥夺影响的细胞类型、基因、转录本和途径的广泛表征。我们还提供了公开可用的教程,旨在让读者将本研究中进行的分析应用于他们自己的数据集。
