The role of Wnt proteins in arthritis
Nature Clinical Practice Rheumatology, 2008Wnt proteins regulate organ development, tumorigenesis and bone homeostasis, among other functions. The binding of Wnt proteins to plasma membrane receptors on mesenchymal cells induces the differentiation of these cells into the osteoblast lineage and thereby supports bone formation.

WNT-mediated relocalization of dishevelled proteins
In Vitro Cellular & Developmental Biology - Animal, 1996The Wnt family of proto-oncogenes encodes secreted signaling proteins that are required for mouse development. The Drosophila Wnt homolog, the wingless (Wg) segment polarity gene, mediates a signal transduction pathway in which the downstream elements appear to be conserved through evolution.

Active Wnt proteins are secreted on exosomes
Nature Cell Biology, 2012Wnt signalling has important roles during development and in many diseases. As morphogens, hydrophobic Wnt proteins exert their function over a distance to induce patterning and cell differentiation decisions. Recent studies have identified several factors that are required for the secretion of Wnt proteins; however, how Wnts travel in the ...

Multiplicity of the interactions of Wnt proteins and their receptors
Cellular Signalling, 2007Wnts are secreted proteins that are essential for a wide array of developmental and physiological processes. They signal across the plasma membranes by interacting with serpentine receptors of the Frizzled (Fz) family and members of the low-density-lipoprotein receptor-related protein (LRP) family.

AbstractThe Wnt family of signalling proteins has essential functions in development and adult tissue homoeostasis throughout the animal kingdom. Although signalling cascades triggered by Wnt proteins have been extensively studied, much remains to be learned about how Wnts are produced and secreted. Over the past few years, it has become clear that the

The Informational Content of Gradients of Wnt Proteins
Science's STKE, 2000This perspective tackles the issues facing developmental biologists and cell biologists regarding how the molecular mechanisms for specifying cell fate are defined. This Perspective focuses on members of the Wnt family. The author proposes that Wnt proteins may act as stabilizing signals for earlier inductive events in certain systems, for

Secretion and extracellular space travel of Wnt proteins
Current Opinion in Genetics & Development, 2013Wnt signaling pathways control many processes during development, stem cell maintenance and homeostasis, and their aberrant regulation has been linked to diseases in man including diabetes, neurodegeneration and cancer. Wnts are hydrophobic proteins, however, quite paradoxically, they can travel over distances to induce cell-type specific responses ...

Isolation and Application of Bioactive Wnt Proteins
2008Wnt proteins and their signaling cascades are involved in a wide variety of developmental processes, and deregulation of this pathway is frequently associated with tumorigenesis. Unlike many other growth factors, Wnts long eluded biochemical purification, in large part because of their hydrophobic nature, which is imparted by one or more lipid ...

Retrograde signalling at the synapse: a role for Wnt proteins
Biochemical Society Transactions, 2005The formation of functional synapses requires a proper dialogue between incoming axons and their future synaptic targets. As axons approach their target, they are instructed to slow down and remodel to form proper presynaptic terminals. Although significant progress has been made in the identification of the mechanisms that control axon guidance ...
