Abstract
Growth arrest specific 1 (GAS1) is a key regulator of mammalian embryogenesis, best known for its role in hedgehog (HH) signaling, but with additional described roles in the FGF, RET, and NOTCH pathways. Previous work indicated a later role for GAS1 in kidney development through FGF pathway modulation. Here, we demonstrate that GAS1 is essential for both mesonephrogenesis and metanephrogenesis - most notably, Gas1 deletion in mice results in renal agenesis in a genetic background-dependent fashion. Mechanistically, GAS1 promotes mesonephrogenesis in a HH-dependent fashion, performing a unique co-receptor function, while promoting metanephrogenesis in a HH-independent fashion, acting as a putative secreted RET co-receptor. Our data indicate that Gas1 deletion leads to renal agenesis through a transient reduction in metanephric mesenchyme proliferation - a phenotype that can be rescued by exogenous RET pathway stimulation. Overall, this study indicates that GAS1 contributes to early kidney development through the integration of multiple different signaling pathways.
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.
