The Wnt signaling mediator tcf1 is required for expression of foxd3 during Xenopus gastrulation

Low doses of Wnt-3a mRNA were injected into the animal caps in combination with Xfz4S to induce Wnt signaling as monitored by the activation of Wnt/ β -catenin target gene Xnr3..

Materials and methods: We immunohistochemically examined various components of Wnt signaling pathway including β -catenin, tumor suppressor proteins, adenomatous polyposis coli

We identified several novel targets upregulated by RA receptor signaling in the early gastrula that are expressed in the circumblastoporal ring and linked to mesodermal

Wnt3a led to low-level induction of NC markers and enhanced induction of Fgf3, Fgf4 and Fgf8 in animal caps, suggesting a positive role for Lrig3 in Wnt signaling.. Lrig3

The phenotypes we observed with expression or depletion of Profilin1 nevertheless suggest a role for this protein in gastrulation, which thus might function in tissue
