Insights

The protein Naked Cuticle-1 (cNkd-1) acts as a switch, promoting non-canonical Wnt signaling. Its dynamic expression in chick embryos suggests a role in somite development and cell movement.

Area of Science:

  • Developmental biology
  • Molecular signaling pathways

Background:

  • Wnt signaling molecules regulate diverse developmental processes in metazoans.
  • Intracellular Wnt response involves activating either canonical (gene expression) or non-canonical (cell polarity/movement) pathways.

Purpose of the Study:

  • To clone and characterize chick Naked Cuticle-1 (cNkd-1).
  • To investigate the role of cNkd-1 in embryonic development, particularly in relation to Wnt signaling pathways.

Main Methods:

  • Cloning of chick Naked Cuticle-1 (cNkd-1).
  • Analysis of cNkd-1 expression patterns during early embryogenesis using techniques like in situ hybridization (implied).
  • Investigating the regulation of cNkd-1 expression by Wnt signaling.

Main Results:

  • Chick Naked Cuticle-1 (cNkd-1) was successfully cloned.
  • cNkd-1 exhibits dynamic expression during early embryogenesis, notably in somites and regions of cell movement.
  • Expression of cNkd-1 is regulated by Wnt signaling originating from the neural tube.

Conclusions:

  • Non-canonical Wnt signaling, mediated by cNkd-1, appears to play a role in chick somite development.
  • cNkd-1 functions as an intracellular switch favoring non-canonical Wnt pathways.

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 Pathways01:41

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...

Notch Signaling Pathway03:14

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...
Determination01:51

Determination

During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In contrast, determination...
Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role 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...
