The proinvasive activity of Wnt-2 is mediated through a noncanonical Wnt pathway coupled to GSK-3beta and c-Jun/AP-1 signaling.

Here, we show that two activators of the canonical Wnt/beta-catenin transcription pathway, namely Dvl-2, the Axin 501-560 fragment binding glycogen synthase kinase -3beta (GSK-3beta), and the negative Wnt regulator wt-Axin did not alter cell invasion into type I collagen.

|
In addition, both Dvl-2 and Axin 501-560 exerted a permissive action on the proinvasive activity of HGF and intestinal trefoil factor.

Upstream activation of Wnt signaling by the Wnt-2 and Wnt-3a ligands, stable overexpression of Wnt-2, as well as GSK-3beta inhibition by lithium, SB216763, and GSK-3beta dominant negative forms (K85R and R96E) conferred the invasive phenotype through several proinvasive pathways.

|
Induction of the matrix metalloprotease MMP-7 (matrilysin) gene and protein by Wnt-2 was abolished by inactivation of the AP-1 binding site in the promoter.
|

|
Accordingly, invasion induced by Wnt-2 was prevented by soluble FRP-3 and FRP-1, sequestration of Gbetagamma subunits, depletion of the GSK-3beta protein by RNA interference, the c-Jun dominant negative mutant TAM67 and was not reversed by wt-Axin.

|
Thus, the proinvasive activity of Wnt-2 is mediated by a noncanonical Wnt pathway using GSK-3beta and the AP-1 oncogene.

Here we describe a modified in vitro procedure to direct differentiation of three clonal hESC lines, hES 3.1, hES 3.2 and hES 3.3 efficiently to spinal motor neurons by using various differentiation factors namely retinoic acid (RA), sonic hedgehog (Shh), bone morphogenetic protein-2 (BMP-2) and Wnt3A.

Regulation of in vitro vascular calcification by BMP4, VEGF and Wnt3a.

|
In addition, these factors render VSMCs responsive to BMP4 and Wnt3a ligands.
|

|
Neither BMP-4 nor Wnt3a could induce mineralization in short-term (up to 8 days) cultures of primary mouse VSMCs.
|

17982705
|
In addition, expression profiling suggests a novel role in vascular calcification for the matrix proteins previously known to regulate bone formation and mineralization (including MMP3, fibulin, 11betahydroxysteroid dehydrogenase 1 and retinoic acid receptor responder 2).

TNF-alpha induces the osteogenic bone morphogenetic protein-2 (BMP-2), Msx2, Wnt3a, and Wnt7a mRNAs and leads to increased aortic calcium accumulation.
|

|
Treatment with the TNF-alpha neutralizing antibody infliximab abrogates aortic BMP-2-Msx2-Wnt3a and Wnt7a signaling and attenuates aortic calcium accumulation significantly.

Mice with vascular TNF-alpha augmented by the SM22-TNF-alpha transgene upregulate the aortic Msx2-Wnt3a/Wnt7a axis.

Wnt3a protein and the beta-catenin (Delta45) mutation increased nuclear beta-catenin but abrogated HG-induced DKK1 and fibronectin expression.

Using this culture system as a model to study human intestinal development, we identified that the combined activity of WNT3A and FGF4 is required for hindgut specification whereas FGF4 alone is sufficient to promote hindgut morphogenesis.
