  • activin
  • Interactions between Nodal/Activin and Fibroblast growth factor (Fgf) signalling pathways have long been thought to play an important role in mesoderm formation. (zfin.org)
  • This could account for the previously described ability of Fgf to render cells competent to respond to Nodal/Activin signals. (zfin.org)
  • In contrast to other TGFβ members, such as Activin, the reception of Nodal also depends on the presence of a co-receptor of the EGF-CFC family ( Shen and Schier, 2000 ). (biologists.org)
  • endoderm
  • As a consequence, anti-Nodal signals from the distal visceral endoderm become opposed to Nodal signals from the proximal epiblast, and together pattern the anteroposterior (AP) axis following movement of the AVE. The molecular regulation of AVE induction and Nodal signaling activities is therefore of central importance for AP axis patterning in the mammalian embryo. (biologists.org)
  • We further show that the co-disruption of extraembryonic Ndr2, extraembryonic Ndr1 and maternal Ndr1 eliminates endoderm and anterior (head and trunk) mesoderm, recapitulating the loss of Nodal signaling phenotype. (biologists.org)

  • The aim of this study is to identify by immunocytochemistry transmembrane proteins enriched in Schwann cells processes that could interact, directly or indirectly, with axonal proteins. (biomedcentral.com)

  • These results suggest that the reduced expression of Oep causes the loss of responsiveness to Nodal signals in the prospective ectoderm. (biologists.org)
  • Indeed, extending the presence of Oep prolongs the window of competence to respond to Nodal signals. (biologists.org)

  • Islets from male mice lacking FoxM1 in β-cells (Foxm1Δβ mice) display attenuated glucose-stimulated insulin secretion, indicating that FoxM1 is a nodal protein regulating the β-cell transition from optimal function to replication (Figure A). Thus, FoxM1 represents a powerful target for T2D therapy. (upenn.edu)
