Targeting the jagged/notch pathway: a new treatment for fibrosis?
1Department of Dentistry, University of Western Ontario, Dental Sciences Building, London, ON Canada N6A 5C1.
Abstract:
There is no treatment for fibrotic disease. TGFβ is known to promote fibrogenesis in vivo and in vitro, however, development of anti-fibrotic strategies targeting the TGFβ axis is problematic owing to the pleitropic nature of TGFβ action. Two recent papers (Kavian et al. 2010; Nyhan et al. 2010) suggest that the jagged/Notch pathway may selectively mediate fibrogenic properties of TGFβ and thus may represent a novel therapeutic approach to fibrosis for scleroderma and kidney fibrosis; these papers are the subject of this commentary.
Insights
Fibrotic diseases lack treatments. Targeting the transforming growth factor beta (TGFβ) pathway is difficult, but the jagged/Notch pathway may offer a new therapeutic approach for fibrosis.
Area of Science:
- Fibrosis research
- Cell signaling pathways
- Molecular medicine
Background:
- Fibrotic diseases remain untreatable, posing significant health challenges.
- Transforming growth factor beta (TGFβ) is a key driver of fibrogenesis.
- Directly targeting TGFβ is complicated by its diverse biological functions.
Purpose of the Study:
- To comment on recent findings suggesting a novel therapeutic strategy for fibrosis.
- To explore the role of the jagged/Notch pathway in mediating TGFβ's fibrogenic effects.
- To evaluate the potential of targeting the jagged/Notch pathway for treating fibrotic conditions.
Main Methods:
- Review and commentary on published research (Kavian et al. 2010; Nyhan et al. 2010).
- Analysis of the proposed mechanism involving the jagged/Notch pathway.
- Discussion of implications for fibrotic disease treatment.
Main Results:
- Recent studies indicate the jagged/Notch pathway selectively mediates TGFβ's fibrogenic properties.
- This pathway presents a potential alternative to direct TGFβ targeting.
- The findings offer new insights into the molecular mechanisms of fibrosis.
Conclusions:
- The jagged/Notch pathway represents a promising novel therapeutic target for fibrotic diseases.
- Targeting this pathway could overcome limitations associated with broad TGFβ inhibition.
- This approach holds potential for treating conditions like scleroderma and kidney fibrosis.

Notch Signaling Pathway
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...
