Circular RNAs as Potential Theranostics in the Cardiovascular System.

Area of Science:

• Molecular Biology
• Genetics
• Cardiology

Background:

• Cardiovascular diseases (CVDs) are a leading cause of global mortality, necessitating new therapeutic targets and biomarkers.
• Circular RNAs (circRNAs), formed by back-splicing, are stable non-coding RNAs increasingly recognized for regulating gene expression.
• CircRNAs play critical roles in cardiovascular physiology and pathology.

Purpose of the Study:

• To review recent findings on the role of circRNAs in cardiac development and CVD pathogenesis.
• To summarize studies identifying circulating circRNAs as potential biomarkers for CVDs.
• To discuss current limitations and future directions in circRNA research for cardiovascular applications.

Main Methods:

• Literature review of studies on circRNAs in cardiovascular development and disease.
• Systematic search for research identifying circulating circRNAs as CVD biomarkers.
• Analysis of functional and clinical study limitations.

Main Results:

• CircRNAs are involved in cardiac development and the progression of various cardiovascular diseases.
• CircRNAs are stable in circulation, making them promising diagnostic and prognostic biomarkers for CVDs.
• Existing research highlights the potential of circRNAs but also points to a need for more functional and clinical validation.

Conclusions:

• CircRNAs represent a significant area of research with potential for novel therapeutic strategies and biomarkers in cardiovascular medicine.
• Further functional studies and robust clinical validation are crucial for translating circRNA discoveries into clinical practice.
• The stability and dynamic expression of circRNAs offer a unique window into cardiovascular health and disease states.
