Insights

Wnt signaling pathways are crucial for tissue and organ development in multicellular organisms. This review explores the molecular mechanisms and biological consequences of Wnt signaling in cell fate specification.

Area of Science:

  • Developmental Biology
  • Cell Signaling

Background:

  • Multicellular organism development relies on complex signaling pathways.
  • Wnt growth factors are key players alongside TGF-beta, FGF, Hedgehog, and Notch signaling.

Purpose of the Study:

  • To review the molecular mechanisms of Wnt signaling.
  • To discuss the biological consequences of Wnt signaling in development.

Main Methods:

  • Literature review of Wnt signaling pathways.

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which results in tumor...

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
