Summary
Notch signaling is crucial for lung development and health. Its dysregulation is linked to lung diseases like cancer, COPD, and fibrosis, highlighting its complex role.
Area of Science:
- Pulmonary Medicine
- Developmental Biology
- Molecular Signaling
Background:
- Notch signaling is vital for organ development and maintaining tissue balance.
- Aberrant Notch signaling is associated with the pathogenesis of several lung diseases, including lung cancer.
Purpose of the Study:
- To review the multifaceted roles of Notch signaling in lung development.
- To explore the involvement of Notch signaling in various lung pathologies.
Main Methods:
- Literature review of Notch signaling functions.
- Analysis of Notch pathway involvement in lung development and disease.
Main Results:
- Notch signaling orchestrates key lung developmental processes: proximodistal patterning, branching morphogenesis, airway epithelial cell differentiation, alveogenesis, and vascular development.
- Dysregulated Notch signaling contributes to chronic obstructive pulmonary disease, pulmonary fibrosis, pulmonary hypertension, asthma, and lung cancer.
Conclusions:
- Notch signaling is a critical regulator throughout lung development.
- Targeting Notch pathways may offer therapeutic strategies for diverse lung diseases.

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...

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...

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
