SnoRNAs in cardiovascular development, function, and disease

Area of Science:

• Cardiovascular Biology
• Molecular Biology
• Genetics

Background:

• Small nucleolar RNAs (snoRNAs) are increasingly recognized for their roles in cardiovascular (patho)biology.
• Their functions extend to heart development, congenital heart diseases, and various cardiomyopathies.
• Altered snoRNA levels are observed in conditions like coronary heart disease (CHD) and myocardial infarction (MI).

Purpose of the Study:

• To review and discuss the key findings on snoRNAs in cardiovascular diseases (CVDs).
• To explore the emerging roles of snoRNAs in heart development and cardiac pathologies.
• To outline the clinical potential of snoRNAs in managing CVDs.

Main Methods:

• Literature review and synthesis of current research on snoRNAs in cardiovascular contexts.
• Analysis of studies investigating snoRNA regulation in different heart conditions.
• Discussion of evidence for snoRNAs in cardiac signaling and intercellular communication.

Main Results:

• SnoRNAs play significant roles in heart development and congenital heart diseases.
• Dynamic regulation of snoRNAs is evident in hypertrophic and dilated cardiomyopathies, CHD, MI, fibrosis, and heart failure.
• Changes in vesicular and circulating snoRNAs suggest roles in cardiac stress response and intercellular communication.

Conclusions:

• SnoRNAs are critical regulators of cardiovascular health and disease.
• Understanding snoRNA functions offers potential for novel diagnostic and therapeutic strategies in CVDs.
• Further research is needed to address current challenges and gaps in the field.
