The ligand-binding pocket of the Dishevelled PDZ domain can be occupied by Dishevelled's own highly conserved C-terminus, inducing a closed conformation that is ‘opened’ when Wnt signaling stimulates interaction between Frizzled and Dishevelled.
Insights into the roles and mechanisms of two of the miRNAs upregulated in human breast cancer stem cells in at least some breast cancers are presented.
A systematic genetic analysis comprising seven genome-wide screens in haploid human cells uncovered new regulatory mechanisms at most levels in the WNT signaling pathway.
Imaging of single cells within a cell population shows the correlation between subcellular accumulation of β-catenin and the transcriptional activation of a target gene.
Cartilage and bone tumors arise from chondrocyte or osteoblast progenitors but not differentiated cells or multipotent mesenchymal stem cells (MSCs) via the IHH-Wnt/β-Catenin pathway.
Dual FAK/PYK2 kinase inhibition disrupts GSK3β phosphorylation and may present a new treatment for colorectal cancer in patients carrying APC mutations.
Injuries activate the oral identity-specifying canonical Wnt signaling pathway in Hydra, which can trigger head regeneration in permissive tissue contexts created by the absence of pre-existing organizers.

Phosphorylation of the Wnt receptor LRP6 directly inhibits glycogen synthase kinase-3 by acting as a pseudosubstrate that stabilizes an active conformation of the enzyme, identical to autoinhibition by phosphorylation of its N terminus.
A novel population of adipocytes that play essential roles in adaptive thermogenesis via cell autonomous and non-autonomous effects and regulate systemic glucose metabolism in mice.
