Summary
NOTCH signaling is crucial for lung development and health. Dysregulation of this pathway is linked to lung diseases like asthma, COPD, and cancer, suggesting potential therapeutic targets.
Area of Science:
- Molecular Biology
- Cell Signaling
- Developmental Biology
Background:
- NOTCH signaling is a vital cell-to-cell communication system regulating embryonic development and tissue homeostasis.
- The NOTCH pathway involves receptor-ligand interactions, gamma-secretase cleavage, and transcriptional activation via RBPJκ.
- This pathway is essential for lung development and maintaining adult lung function.
Purpose of the Study:
- To provide an overview of NOTCH signaling's role in lung development and homeostasis.
- To illustrate the regulatory functions of NOTCH in various pulmonary diseases.
- To discuss potential NOTCH-targeted therapies for lung pathologies.
Main Methods:
- Review of in vitro and in vivo studies on NOTCH signaling.
- Analysis of mechanisms underlying NOTCH's role in lung diseases.
- Exploration of therapeutic strategies targeting NOTCH.
Main Results:
- NOTCH signaling is integral to lung development and homeostasis.
- Aberrations in NOTCH signaling are associated with asthma, COPD, pulmonary arterial hypertension, and lung cancer.
- Specific mechanisms link NOTCH dysregulation to these pulmonary conditions.
Conclusions:
- NOTCH signaling plays a critical role in lung health and disease.
- Understanding NOTCH's function in the lung offers insights into disease pathogenesis.
- Targeting the NOTCH pathway presents a promising therapeutic avenue for lung diseases.

03:14Notch Signaling Pathway
6.7K
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
2.5K
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...

01:24Regulation of Angiogenesis and Blood Supply
3.8K
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...

02:33Hedgehog Signaling Pathway
10.2K
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...

01:30Pulmonary Hypertension: Classification and Pathogenesis
721
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

01:20COPD: Pathogenesis and Clinical Features
2.0K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
