Long noncoding RNA in cardiac aging and disease

Area of Science:

• Cardiovascular biology
• Molecular genetics
• RNA biology

Background:

• Cardiovascular diseases (CVDs) are a leading cause of death and disability, particularly in aging populations.
• Increasing life expectancy suggests a growing prevalence of CVDs, necessitating novel therapeutic strategies.
• Long noncoding RNAs (lncRNAs) are emerging as critical regulators in various biological processes, including cardiac function.

Purpose of the Study:

• To review the current understanding of lncRNA regulation in the context of cardiovascular diseases.
• To explore the potential of lncRNAs as biomarkers for the early detection and prediction of cardiac conditions.
• To highlight the significance of lncRNAs in the pathophysiology of heart disease.

Main Methods:

• Comprehensive literature review of recent studies on lncRNA function in cardiovascular diseases.
• Analysis of RNA sequencing data to identify non-coding RNAs in cardiac tissues.
• Synthesis of findings regarding lncRNA mechanisms in cardiac disease models and human studies.

Main Results:

• A significant portion of the transcriptome consists of non-coding RNAs, including lncRNAs, with diverse regulatory roles.
• Specific lncRNAs have been identified that are dysregulated in various cardiac pathologies.
• Evidence suggests lncRNAs can influence cardiac structure and function through epigenetic, transcriptional, and post-transcriptional mechanisms.

Conclusions:

• lncRNAs represent a novel class of molecules with substantial implications for cardiovascular health and disease.
• Dysregulation of lncRNAs is implicated in the development and progression of CVDs.
• lncRNAs hold promise as potential diagnostic and prognostic biomarkers for cardiovascular diseases, especially in the elderly.
