Computational modelling together with experimental manipulation indicate that the stability and turnover of activated Notch is inextricably linked to the regulation of the pace of segmentation clock gene expression in the presomitic mesoderm.
The basic helix-loop-helix transcription factor, HES3, acts downstream of the PAX3-FOXO1 fusion oncogene to impair muscle differentiation and promote tumorigenesis in rhabdomyosarcoma, a childhood muscle cancer.
Genetic analyses demonstrate that Gdf3/Vg1 is a maternal effect gene required for robust Nodal signaling during different phases of embryogenesis including germ-layer formation, Kupffer's vesicle morphogenesis, and left-right patterning.
At gastrulation, mesoderm arises as a migratory germ layer that will participate to both foetal and placental development through region-dependant adaptation of cytoskeleton composition, cell shape and migration mode.
Analysis of a double mutant in the Hippo pathway transcription factors Yap1 and Wwtr1 reveals novel roles for these factors in posterior body formation and epidermal morphogenesis in the vertebrate embryo.
