MicroRNAs (miRNAs) are epigenetic regulators in systemic sclerosis (SSc), a fibrotic autoimmune disease. This review highlights their role in TGF-β signaling, offering potential for new SSc biomarkers and treatments.
Area of Science:
- Immunology
- Genetics
- Molecular Biology
Background:
- Systemic sclerosis (SSc) is a complex multisystem fibrotic and autoimmune disease.
- Both genetic and epigenetic factors contribute to SSc pathophysiology.
- MicroRNAs (miRNAs) represent a key class of epigenetic regulators.
Purpose of the Study:
- To review the role of miRNAs in the pathogenesis of systemic sclerosis (SSc).
- To focus on miRNA regulation of the transforming growth factor-β (TGF-β) signaling pathway, particularly upstream components.
- To explore the potential of miRNAs as biomarkers and therapeutic targets in SSc.
Main Methods:
- Literature review summarizing current research on miRNAs in SSc.
- Analysis of miRNA involvement in key signaling pathways, with emphasis on TGF-β.
- Discussion of emerging evidence regarding miRNAs in SSc vasculopathy.
Main Results:
- miRNAs regulate key components of the TGF-β signaling pathway, both upstream and downstream.
- Specific focus on upstream regulators of TGF-β by miRNAs in SSc.
- Emerging evidence indicates a significant role for miRNAs in SSc-related vasculopathy.
Conclusions:
- miRNAs are crucial epigenetic regulators in SSc pathogenesis.
- Understanding miRNA regulation of signaling factors can lead to novel SSc biomarkers.
- Targeting miRNAs presents a promising avenue for improving SSc treatment and understanding.
