Non-Coding RNAs in Stem Cell Regulation and Cardiac Regeneration: Current Problems and Future Perspectives

Area of Science:

• Cardiovascular Biology
• Regenerative Medicine
• Molecular Biology

Background:

• Acute myocardial infarction (AMI) leads to cardiomyocyte loss and impaired ventricular function, often resulting in heart failure.
• The heart's poor regenerative capacity necessitates novel therapeutic strategies for myocardial repair.
• Current stem cell therapies for cardiac repair face challenges like poor retention and oncogenic risks.

Purpose of the Study:

• To review the role of non-coding RNAs (ncRNAs) in regulating stem cells for cardiac regeneration.
• To explore the potential of circular RNAs (circRNAs) and microRNAs (miRNAs) in activating resident cells or stem cells for myocardial repair.
• To discuss the advantages of ncRNAs as regulators of stem cells and drivers of cardiac regeneration.

Main Methods:

• Literature review focusing on ncRNAs, stem cell regulation, and cardiac regeneration.
• Analysis of studies investigating circRNAs and miRNAs in the context of myocardial repair.
• Synthesis of findings on the therapeutic potential of ncRNAs in cardiovascular disease.

Main Results:

• ncRNAs, including circRNAs and miRNAs, play crucial roles in cell proliferation and differentiation.
• These ncRNAs can regulate stem cell activity and potentially induce stem cell status in resident cells.
• ncRNAs offer an alternative strategy to direct stem cell delivery for cardiac repair.

Conclusions:

• ncRNAs represent a promising avenue for cardiac regeneration, addressing limitations of traditional stem cell therapies.
• circRNAs and miRNAs are key regulators with significant potential for stimulating myocardial repair and improving ventricular function post-AMI.
• Further research into ncRNA-based therapies could lead to effective treatments for heart failure following myocardial infarction.
