Noncoding RNAs in Cardiac Hypertrophy

Area of Science:

• Cardiology
• Molecular Biology
• Genetics

Background:

• Cardiac hypertrophy, a thickening of the heart muscle, is classified as either pathological or physiological.
• Pathological hypertrophy is linked to heart failure, a major global health issue.
• Physiological hypertrophy is an adaptive response that protects the heart.

Purpose of the Study:

• To review the role of noncoding RNAs (ncRNAs) in cardiac hypertrophy.
• To summarize the profiling, function, and molecular mechanisms of specific ncRNAs (microRNAs, long noncoding RNAs, circular RNAs) in pathological cardiac hypertrophy.
• To examine microRNAs involved in physiological hypertrophy.

Main Methods:

• Literature review and synthesis of existing research on ncRNAs and cardiac hypertrophy.
• Analysis of studies focusing on microRNAs, long noncoding RNAs, and circular RNAs.
• Examination of molecular mechanisms and functional roles in cardiac remodeling.

Main Results:

• Dysregulation of ncRNAs is increasingly associated with cardiac hypertrophy and cardiovascular diseases.
• Specific ncRNAs, including microRNAs, long noncoding RNAs, and circular RNAs, are implicated in the development of pathological cardiac hypertrophy.
• Certain microRNAs are identified as key regulators of physiological hypertrophy.

Conclusions:

• Noncoding RNAs are critical players in both pathological and physiological cardiac hypertrophy.
• Understanding the precise roles and mechanisms of ncRNAs in cardiac hypertrophy provides a foundation for novel therapeutic interventions.
• Targeting specific ncRNAs presents promising avenues for the prevention and treatment of heart failure.
