Small but smart: MicroRNAs orchestrate atherosclerosis development and progression.

Area of Science:

• Molecular Biology
• Cardiovascular Biology
• Genetics

Background:

• MicroRNAs (miRNAs) are short non-coding RNAs regulating gene expression post-transcriptionally.
• miRNAs are vital in vertebrate cellular processes like proliferation, differentiation, and apoptosis.
• Growing evidence implicates miRNAs in human pathology, particularly atherosclerosis.

Purpose of the Study:

• To review and summarize the role of miRNAs in atherogenesis.
• To explore miRNA involvement across the spectrum of atherosclerosis, including risk factors and plaque progression.
• To identify research gaps and potential translational applications of miRNAs in cardiovascular disease.

Main Methods:

• Literature review of in vitro, in vivo, and clinical studies.
• Synthesis of current knowledge on miRNA function in atherogenesis.
• Analysis of miRNA involvement in risk factors (dyslipidemia, diabetes, hypertension), endothelial dysfunction, and plaque rupture.

Main Results:

• miRNAs are key regulators in multiple stages of atherosclerosis.
• Specific miRNAs are implicated in modulating risk factors and cellular events contributing to plaque development.
• Evidence supports a significant contribution of miRNAs to the pathogenesis of atherosclerosis.

Conclusions:

• miRNAs play a critical role throughout the continuum of atherogenesis.
• Further research is needed to fully elucidate miRNA mechanisms and therapeutic potential.
• Targeting miRNAs offers promising avenues for future translational applications in cardiovascular disease management.
