Gdf3 is required for robust Nodal signaling during germ layer formation and left-right patterning
Vertebrate embryonic patterning depends on signaling from Nodal, a TGFβ superfamily member. There are three Nodal orthologs in zebrafish; southpaw directs left-right asymmetries, while squint and cyclops function earlier to pattern mesendoderm. TGFβ member Vg1 is implicated in mesoderm formation but the role of the zebrafish ortholog, Growth differentiation factor 3 (Gdf3), has not been fully e...
متن کاملBMP2 is a positive regulator of Nodal signaling during left-right axis formation in the chicken embryo.
A model of left-right axis formation in the chick involves inhibition of bone morphogenetic proteins by the antagonist Car as a mechanism of upregulating Nodal in the left lateral plate mesoderm. By contrast, expression of CFC, a competence factor, which is absolutely required for Nodal signaling in the lateral plate mesoderm is dependent on a functional BMP signaling pathway. We have therefore...
متن کاملCcd1, a Novel Protein with a DIX Domain, Is a Positive Regulator in the Wnt Signaling during Zebrafish Neural Patterning
Wnt signaling plays a crucial role in directing cell differentiation, polarity, and growth. In the canonical pathway, Wnt receptors activate Dishevelled (Dvl), which then blocks the degradation of a key signal transducer, beta-catenin, leading to the nuclear accumulation of beta-catenin and induction of Wnt target genes through TCF/LEF family transcription factors. Here we identified a novel ze...
متن کاملALK7, a receptor for nodal, is dispensable for embryogenesis and left-right patterning in the mouse.
Mesendoderm formation and left-right patterning during vertebrate development depend upon selected members of the transforming growth factor beta superfamily, particularly Nodal and Nodal-related ligands. Two type I serine/threonine kinase receptors have been identified for Nodal, ALK4 and ALK7. Mouse embryos lacking ALK4 fail to produce mesendoderm and die shortly after gastrulation, resemblin...
متن کاملCelf1 regulation of dmrt2a is required for somite symmetry and left-right patterning during zebrafish development.
RNA-binding proteins (RBPs) bind to numerous and diverse mRNAs to control gene expression post-transcriptionally, although the in vivo functions of specific RBP-mRNA interactions remain largely unknown. Here, we show that an RBP named Cugbp, Elav-like family member 1 (Celf1) controls expression of a gene named doublesex and mab-3 related transcription factor 2a (dmrt2a), which is essential for ...
