Wnt signalling inhibits neural differentiation of embryonic stem cells by controlling bone morphogenetic protein expression


Haegele, L; Ingold, B; Naumann, H; Tabatabai, G; Ledermann, B; Brandner, S (2003). Wnt signalling inhibits neural differentiation of embryonic stem cells by controlling bone morphogenetic protein expression. Molecular and Cellular Neuroscience, 24(3):696-708.

Abstract

Wnt signalling plays an important role in both embryonic development and in tumourigenesis. Activation of the signalling cascade by wnt, but also mutations of the adenomatous polyposis coli (APC) protein and of the phosphorylation domain of beta-catenin, result in accumulation of active beta-catenin in the nucleus, where it binds to TCF/LEF transcription factors. We studied the effect of wnt signalling in embryonic stem cells by either inactivating APC or by introducing a dominant active form of beta-catenin. Both resulted in inhibition of neural differentiation in vitro and after brain grafting and in activation of downstream targets of wnt signalling, such as cyclins, c-myc, and bone morphogenetic proteins (BMP). Neural differentiation could be partially restored by the addition of the BMP antagonist noggin. This suggests a mechanism regulating the fate of differentiating embryonic stem cells.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
