Insights

Wnt signaling, crucial in development and cancer, involves beta-catenin stabilization. This pathway regulates genes essential for stem cell functions, offering new therapeutic targets.

Area of Science:

  • Molecular Biology
  • Developmental Biology
  • Cancer Biology

Context:

  • Wnt signaling research originated from Drosophila genetic analyses in the 1970s.
  • Wnt signaling impacts diverse biological fields, including developmental and tumor biology.
  • The canonical Wnt pathway, mediated by beta-catenin, is extensively studied.

Purpose:

  • To elucidate the mechanisms of beta-catenin degradation and stabilization within the Wnt pathway.
  • To identify genes regulated by the canonical Wnt signaling pathway.
  • To understand the role of Wnt-regulated genes in stem cell functions.

Summary:

Canonical Wnt Signaling Pathway02:54

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...

Diversity in Cell Signaling Responses

The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.

NF-kB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.
