Role of noncoding RNA in vascular remodelling

Area of Science:

• Vascular Biology
• Molecular Medicine
• Genetics

Background:

• Noncoding RNAs (ncRNAs) are increasingly recognized for their roles in vascular pathophysiology.
• ncRNAs regulate critical cellular processes in endothelial cells and vascular smooth muscle cells.

Purpose of the Study:

• To review the involvement of ncRNAs in injury-induced vascular remodelling.
• To highlight the role of ncRNAs in specific vascular conditions like vein graft disease, in-stent restenosis, and pulmonary arterial hypertension.
• To discuss the emerging role of exosomal ncRNAs in vascular cell communication and function.

Main Methods:

• Literature review of recent studies on ncRNAs in vascular disease.
• Focus on microRNAs (miRNAs) and long noncoding RNAs (lncRNAs).
• Examination of ncRNA involvement in endothelial and smooth muscle cell function.

Main Results:

• ncRNAs are novel regulators of vascular injury, inflammation, and remodelling.
• miRNA manipulation can mitigate pathological vascular remodelling.
• Exosomal miRNA-mediated cell-to-cell communication is crucial in vascular disease.
• lncRNAs are emerging as significant regulators of vascular function.

Conclusions:

• ncRNAs play fundamental roles in vascular injury and remodelling.
• The cell-to-cell communication mediated by ncRNAs is critical.
• Modulating ncRNAs presents a promising therapeutic strategy for vascular diseases.
