Summary
Notch3 protein signaling is vital for cell fate during development and tissue renewal in adults. Its misregulation is linked to cancers and diseases like CADASIL, highlighting its therapeutic potential.
Area of Science:
- Molecular Biology
- Developmental Biology
- Cell Biology
Background:
- Notch3 is a key signaling receptor controlling cell fate in development and adult tissues.
- Notch signaling is crucial for tissue maintenance, renewal, and stem cell regulation.
- Dysregulation of Notch3 is implicated in various diseases, including cancer and vascular disorders.
Purpose of the Study:
- To discuss the distinct roles of Notch3 in development, health, and disease.
- To explore mechanisms of Notch3 activation and misregulation.
- To examine the potential for therapeutic interventions targeting Notch3.
Main Methods:
- Review of genetic studies on Notch3 gene knockouts.
- Analysis of Notch3's role in stem cell regulation and vascular smooth muscle plasticity.
- Examination of Notch3's association with cancers and inherited diseases.
Main Results:
- Notch3 plays essential roles in arterial smooth muscle cell lineage development.
- Notch3 collaborates with other Notch proteins in adult stem cell regulation and vascular remodeling.
- Notch3 overexpression/mis-activation is linked to triple-negative breast and ovarian cancers.
- Notch3 mutations cause CADASIL, and its misregulation is linked to hypertension.
Conclusions:
- Notch3 has diverse functions in development and adult tissue homeostasis.
- Notch3 misregulation contributes to significant human diseases, including cancer and CADASIL.
- Understanding Notch3 mechanisms offers potential for novel therapeutic strategies.

03:14Notch Signaling Pathway
6.3K
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...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.4K
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...

01:18Models of Health Promotion and Illness Prevention II
1.9K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

01:29Three Developmental Domains
851
Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

01:23Cystic Fibrosis: Pathogenesis
646
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
