Insights

MicroRNAs (miRNAs) are key regulators in human cells, impacting gene expression and disease. This review explores their specific role in atherosclerosis, focusing on vulnerable plaque development.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are endogenous nucleotides regulating gene expression in metazoan cells.
  • Discovered in 1993 and identified in humans in 2000, miRNAs are implicated in development, homeostasis, and pathology.
  • Approximately 700 human miRNAs influence 30% of all human genes.

Purpose of the Study:

  • This review focuses on the role of miRNAs in atherosclerosis.
  • Specifically examines the potential involvement of miRNAs in the development of vulnerable atherosclerotic plaques.
  • Discusses miRNA involvement in key plaque characteristics: inflammation, angiogenesis, and apoptosis.

Main Methods:

  • Literature review of scientific publications on miRNAs and atherosclerosis.
  • Analysis of existing research on miRNA function in cardiovascular disease.
  • Synthesis of data regarding miRNA roles in inflammation, angiogenesis, and apoptosis within atherosclerotic plaques.

Main Results:

  • miRNAs play a significant role in the pathogenesis of atherosclerosis.
  • Specific miRNAs are implicated in the development and progression of vulnerable atherosclerotic plaques.
  • miRNA dysregulation contributes to inflammation, aberrant angiogenesis, and apoptosis in plaque development.

Conclusions:

  • miRNAs are crucial in cardiovascular research, particularly in understanding atherosclerosis.
  • miRNAs hold potential as diagnostic biomarkers for vulnerable atherosclerotic plaques.
  • miRNA-based therapeutic strategies offer promising future directions for treating atherosclerosis.

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
