... is a key mediator of the Wnt signalling pathway ( Clevers and Nusse, 2012 ). Although we do not rule out a contribution of DACT in non-canonical Wnt signalling, as previously shown in Xenopus embryos ( Park et al., 2006 ; Wen et al., 2010 ; Kivimäe et al., 2011 ), our results show a strong...

... and amphibian embryos. Here, we analyze the molecular mechanisms of neural crest induction by the mesoderm in Xenopus embryos. Using a recombination assay, we show that prospective paraxial mesoderm induces a panel of neural crest markers ( Slug, FoxD3, Zic5 and Sox9 ),whereas the future axial mesoderm only...

...Jing Yang; Change Tan; Rachel S. Darken; Paul A. Wilson; Peter S. Klein Following fertilization, the zygotic genome in many organisms is quiescent until the midblastula transition (MBT), when large-scale transcription begins. In Xenopus embryos, for example, transcription is believed...
