Abstract
Gene regulators physically associate with the genome, in a combinatorial fashion, to drive tissue-specific gene expression. Uncovering the genome-wide activity of all gene regulators across tissues is therefore needed to understand gene regulation during development. Here, we take a first step towards this goal. Using CUT&RUN, we systematically mapped genome-wide binding profiles of key transcription factors and co-factors that mediate ontogenetically relevant signaling pathways in select mouse tissues at two developmental stages. Computation of the datasets unveiled tissue- and time-specific activity for each gene regulator. We identified 'popular' regulatory regions that are bound by a multitude of regulators, which tend to be more evolutionarily conserved. Consistently, they lie near the transcription start site of genes for which dysregulation results in early embryonic lethality. Moreover, the human homologs of these regions are similarly bound by many gene regulators and are highly conserved, indicating a retained relevance for human development. This work constitutes a decisive step towards understanding how the genome is simultaneously read and used by gene regulators in a holistic fashion to drive embryonic development.
期刊介绍：
Development’s scope covers all aspects of plant and animal development, including stem cell biology and regeneration. The single most important criterion for acceptance in Development is scientific excellence. Research papers (articles and reports) should therefore pose and test a significant hypothesis or address a significant question, and should provide novel perspectives that advance our understanding of development. We also encourage submission of papers that use computational methods or mathematical models to obtain significant new insights into developmental biology topics. Manuscripts that are descriptive in nature will be considered only when they lay important groundwork for a field and/or provide novel resources for understanding developmental processes of broad interest to the community.
Development includes a Techniques and Resources section for the publication of new methods, datasets, and other types of resources. Papers describing new techniques should include a proof-of-principle demonstration that the technique is valuable to the developmental biology community; they need not include in-depth follow-up analysis. The technique must be described in sufficient detail to be easily replicated by other investigators. Development will also consider protocol-type papers of exceptional interest to the community. We welcome submission of Resource papers, for example those reporting new databases, systems-level datasets, or genetic resources of major value to the developmental biology community. For all papers, the data or resource described must be made available to the community with minimal restrictions upon publication.
To aid navigability, Development has dedicated sections of the journal to stem cells & regeneration and to human development. The criteria for acceptance into these sections is identical to those outlined above. Authors and editors are encouraged to nominate appropriate manuscripts for inclusion in one of these sections.
