Circular RNAs Regulate Vascular Remodelling in Pulmonary Hypertension

Area of Science:

• Molecular Biology
• Genetics
• Cardiovascular Research

Background:

• Circular RNAs (circRNAs) are a distinct class of noncoding RNA characterized by a unique closed-loop structure.
• These molecules are ubiquitously expressed across various tissues and developmental stages, implicating them in critical pathophysiological processes.
• circRNAs play significant roles in the development and progression of numerous diseases.

Purpose of the Study:

• To review the discovery, characteristics, formation, and biological functions of circRNAs.
• To elucidate the relationship between circRNAs and vascular remodeling.
• To discuss the current research status and potential applications of circRNAs in pulmonary hypertension (PH).

Main Methods:

• Literature review synthesizing existing research on circRNAs.
• Analysis of circRNA involvement in cellular processes relevant to vascular remodeling.
• Evaluation of current studies and future prospects concerning circRNAs in PH.

Main Results:

• circRNAs are integral to the regulation of vascular endothelial and smooth muscle cell remodeling.
• A growing body of evidence links circRNAs to the pathogenesis of pulmonary hypertension.
• circRNAs demonstrate significant potential for diagnostic and therapeutic applications in PH.

Conclusions:

• circRNAs are closely associated with vascular remodeling processes relevant to PH.
• Further investigation into circRNAs' role in PH pathogenesis offers promising avenues for research.
• Understanding circRNAs can advance the screening, diagnosis, prevention, and treatment of PH.
