Insights
Calcium (Ca2+) signaling is vital for heart function. This review explores how calcium-related microRNAs (miRNAs) impact heart diseases like hypertrophy and heart failure, offering potential therapeutic targets.
Area of Science:
- Cardiovascular Biology
- Molecular Cardiology
- Gene Regulation
Background:
- Calcium (Ca2+) signaling is essential for cardiac muscle contraction, electrical activity, and cell growth.
- Dysregulation of Ca2+ handling proteins is a hallmark of heart disease.
- MicroRNAs (miRNAs) are key regulators of gene expression, influencing cardiac Ca2+ cycling.
Purpose of the Study:
- To review the role of cardiac Ca2+ signaling in pathological conditions.
- To summarize the involvement of Ca2+-related miRNAs in heart diseases.
- To discuss the therapeutic potential of miRNAs targeting Ca2+ handling.
Main Methods:
- Literature review of studies on cardiac Ca2+ signaling.
- Analysis of research on miRNAs in cardiac hypertrophy, heart failure, myocardial infarction, and atrial fibrillation.
- Synthesis of findings on miRNA-mediated regulation of Ca2+ handling.
Main Results:
- Impaired Ca2+ handling is central to various heart diseases.
- Specific miRNAs are implicated in the pathophysiology of cardiac hypertrophy, heart failure, myocardial infarction, and atrial fibrillation.
- Ca2+-related miRNAs represent promising biomarkers and therapeutic targets.
Conclusions:
- Cardiac Ca2+ signaling is critically regulated by miRNAs.
- Understanding miRNA-Ca2+ interactions is crucial for diagnosing and treating heart diseases.
- Targeting Ca2+-related miRNAs offers a novel therapeutic strategy for cardiovascular conditions.
Abstract:
In hearts, calcium (Ca2+) signaling is a crucial regulatory mechanism of muscle contraction and electrical signals that determine heart rhythm and control cell growth. Ca2+ signals must be tightly controlled for a healthy heart, and the impairment of Ca2+ handling proteins is a key hallmark of heart disease. The discovery of microRNA (miRNAs) as a new class of gene regulators has greatly expanded our understanding of the controlling module of cardiac Ca2+ cycling. Furthermore, many studies have explored the involvement of miRNAs in heart diseases. In this review, we aim to summarize cardiac Ca2+ signaling and Ca2+-related miRNAs in pathological conditions, including cardiac hypertrophy, heart failure, myocardial infarction, and atrial fibrillation. We also discuss the therapeutic potential of Ca2+-related miRNAs as a new target for the treatment of heart diseases.
