Summary
Wnt signaling, crucial for cell behavior, impacts craniofacial development. This review details its essential roles in upper lip and palate formation, offering insights into birth defects.
Area of Science:
- Developmental Biology
- Genetics
- Cell Signaling
Background:
- Wnt signaling is a fundamental pathway regulating cell behaviors during development and disease.
- Mutations in Wnt pathway genes are linked to craniofacial abnormalities, notably cleft lip and palate.
- The precise roles of Wnt signaling in lip and palate development were previously unclear.
Purpose of the Study:
- To review recent studies on Wnt signaling's function in upper lip and palate development.
- To elucidate the differential roles of canonical and non-canonical Wnt pathways.
- To connect Wnt signaling functions to craniofacial birth defects.
Main Methods:
- Literature review of recent studies on Wnt signaling in craniofacial development.
- Analysis of genetic networks controlling lip and palate morphogenesis.
- Examination of Wnt pathway involvement in disease settings.
Main Results:
- Both canonical (β-catenin-dependent) and non-canonical Wnt pathways are essential for lip and palate development.
- Wnt signaling plays critical roles in upper lip formation and secondary palate development.
- Understanding these pathways advances knowledge of craniofacial development and related birth defects.
Conclusions:
- Wnt signaling is indispensable for normal craniofacial development, particularly lip and palate formation.
- Recent research has significantly clarified the functions of Wnt pathways in these processes.
- These findings are vital for understanding craniofacial birth defects and developing future therapies.

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...

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...

01:12Role 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...
