WNT signaling pathway and stem cell signaling network
1M and M Medical BioInformatics, Hongo, Japan.
Summary
WNT signaling pathways regulate cell fate and movement, with disruptions linked to cancer. Inhibiting these pathways shows promise for cancer prevention and treatment using novel compounds and antibodies.
Area of Science:
- Cellular Biology
- Molecular Biology
- Cancer Research
Background:
- WNT signaling is crucial for cell fate determination and tissue polarity, operating through canonical and noncanonical pathways.
- The canonical WNT pathway involves beta-catenin signaling, regulated by numerous positive and negative intracellular factors.
- Aberrant WNT signaling, particularly loss-of-function mutations in negative regulators, is implicated in human cancers.
Purpose of the Study:
- To elucidate the intricate mechanisms of WNT signal transduction through canonical and noncanonical pathways.
- To identify key regulators and target genes within the WNT signaling network.
- To explore the therapeutic potential of targeting WNT signaling for cancer chemoprevention and treatment.
Main Methods:
- Analysis of WNT signal transduction cascades, including receptor-coreceptor interactions and downstream effectors.
- Identification of positive and negative regulators of the canonical WNT pathway.
- Investigation of WNT pathway involvement in stem cell homeostasis and carcinogenesis.
- Evaluation of potential therapeutic agents targeting the WNT pathway.
Main Results:
- Canonical WNT signaling regulates cell fate via beta-catenin, while noncanonical pathways control cell movement and polarity.
- A complex network of regulators modulates WNT signal transduction, with context-dependent pathway activation.
- Disruption of WNT signaling networks contributes to carcinogenesis.
- Specific compounds and antibodies targeting WNT signaling demonstrate potential for cancer therapy.
Conclusions:
- WNT signaling pathways are fundamental to cellular processes and tissue homeostasis.
- Dysregulation of WNT signaling is a critical factor in cancer development.
- Targeting WNT signaling pathways offers promising therapeutic strategies for cancer prevention and treatment.

02:54Canonical 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...

01:41Non-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...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

03:14Notch 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...
