Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

10.7K
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...

Non-Canonical Wnt Signaling Pathways

8.5K
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...

Endocrine Signaling01:45

Endocrine Signaling

68.2K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Bacterial Signaling01:30

Bacterial Signaling

40.9K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Yeast Signaling01:28

Yeast Signaling

17.3K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

What is Cell Signaling?

131.0K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Area of Science:

  • Developmental Biology
  • Cell Signaling
  • Otolaryngology

Background:

  • Wnt signaling plays vital roles in embryonic development and organogenesis.
  • In the inner ear, Wnt signaling is essential for otic specification, vestibular structure formation, and cochlear development.
  • Dissecting Wnt pathways in the mammalian cochlea is challenging due to limited data, particularly during proliferation.

Purpose of the Study:

  • To review and consolidate known Wnt signaling pathways in cochlear development.
  • To generate a potential timeline of cochlear development by integrating Wnt roles from other biological systems.
  • To predict Wnt activity in the mammalian cochlea by comparative analysis.

Main Methods:

  • Comparative analysis of Wnt signaling in cochlear development with other systems (Xenopus retina, brain, cancer, osteoblasts).
  • Integration of known signaling pathways in the cochlea with established developmental roles of Wnts.
  • Literature review and data consolidation.

Main Results:

  • Wnt signaling interacts with other pathways like Notch and FGF.
  • These interactions influence the expression of key developmental genes, including Sox2 and proneural genes.
  • A potential timeline for Wnt-mediated cochlear development is proposed.

Conclusions:

  • Wnt signaling is a key regulator of cochlear development.
  • Crosstalk with other signaling pathways is critical for Wnt function in the cochlea.
  • This review provides a framework for understanding Wnt-driven cochlear development.
