Dorsal raphe Pet1 neurons are molecularly heterogeneous, comprising as many as fourteen distinct subtypes that show biased cell body distributions across dorsal raphe subdomains.
Loss of MeCP2 function negatively impacts Tet1 and CTCF binding thereby negatively impacting learning-dependent DNA methylation and alternative splicing regulation.
Light signaling components interact with a histone H2B deubiquitination module, adjusting chromatin states at global level during Arabidopsis seedling development.
Pet1 neurons actively maintain cardiorespiratory tone and dynamic range in mouse neonates and critically support the recovery response to apneas, informing brain findings in the sudden infant death syndrome.
The protein Pat1 functions in the assembly of processing bodies, cellular membraneless organelles, by promoting the liquid–liquid phase separation of the DEAD-box ATPase Dhh1 and RNA.
The rat is much more than a simple model, and a better appreciation of the natural history of wild rats would increase its value as a research organism.
Epigenetic transcriptional memory employs a novel regulatory strategy to create a heritable poised state by remodeling and repurposing complexes involved in active transcription.
