SOX2-Dependent Transcription in Clock Neurons Promotes the Robustness of the Central Circadian Pacemaker.

Cell reports | 2019

Clock neurons within the mammalian suprachiasmatic nuclei (SCN) encode circadian time using interlocked transcription-translation feedback loops (TTFLs) that drive rhythmic gene expression. However, the contributions of other transcription factors outside of the circadian TTFLs to the functionality of the SCN remain obscure. Here, we report that the stem and progenitor cell transcription factor, sex-determining region Y-box 2 (SOX2), is expressed in adult SCN neurons and positively regulates transcription of the core clock gene, Period2. Mice lacking SOX2 selectively in SCN neurons display imprecise, poorly consolidated behavioral rhythms that do not entrain efficiently to environmental light cycles and that are highly susceptible to constant light-induced arrhythmicity. RNA sequencing revealed that Sox2 deficiency alters the SCN transcriptome, reducing the expression of core clock genes and neuropeptide-receptor systems. By defining the transcriptional landscape within SCN neurons, SOX2 enables the generation of robust, entrainable circadian rhythms that accurately reflect environmental time.

Clocklab (tool)

RRID:SCR_014309

Point and click program used to quickly analyse circadian activity data using algorithms and embedded controls to make every graph interactive and useful for data analysis. The analysis program has been used for a variety of species including mice, hamsters, rats, sheep, Drosophila, and humans. This program has three separate applications: one for data collection, one for analysis, and a chamber control program.
