Insights
Circular RNAs (circRNAs) are key regulators in cardiovascular development and disease. These stable molecules show promise as novel biomarkers for cardiovascular diseases (CVDs).
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 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.
Abstract:
Cardiovascular diseases (CVDs) represent the largest contributor to mortality worldwide. Identification of novel therapeutic targets and biomarkers for CVDs is urgently needed. Circular RNAs (circRNAs) are endogenous, abundant, and stable non-coding RNAs formed by back-splicing events. Their role as regulators of gene expression has been increasingly reported. Notably, circRNAs mediate essential physiological and pathological processes in the cardiovascular system. Our first aim, therefore, is to summarize recent advances in the role of circRNAs in cardiac development as well as in pathogenesis of various CVDs. Because circRNAs are stable in circulation and their dynamic changes may reflect different disease stages, they are considered ideal biomarkers. Therefore, our second aim is to review studies that have identified circulating circRNAs as biomarkers for CVDs. Finally, we discuss the shortage of functional studies and the limitations of available clinical studies and provide future perspectives.
