Insights

MicroRNAs (miRNAs) are key regulators in atherosclerosis, influencing lipid dysfunction, inflammation, and aging. This review explores how miRNA dysregulation drives vascular aging and atherosclerotic disease progression.

Area of Science:

  • Cardiovascular Biology
  • Molecular Biology
  • Aging Research

Background:

  • Atherosclerosis is driven by lipid dysfunction, inflammation, immune responses, and aging.
  • MicroRNAs (miRNAs) are critical post-transcriptional gene regulators involved in vascular pathologies associated with aging.
  • Dysregulated miRNAs play a significant role in all stages of atherosclerotic disease, from plaque formation to rupture.

Purpose of the Study:

  • To review recent advances in understanding the role of miRNAs in vascular aging.
  • To elucidate the complex pathophysiological mechanisms by which miRNAs regulate atherosclerosis.
  • To focus on the impact of miRNAs on endothelial cells and immune systems in vascular aging.

Main Methods:

  • Literature review of recent studies on miRNAs and atherosclerosis.
  • Analysis of miRNA involvement in endothelial cells and immune responses.
  • Synthesis of current knowledge on miRNA regulation in vascular aging.

Main Results:

  • miRNAs are crucial regulators in the initiation and progression of atherosclerosis.
  • miRNA dysregulation is implicated in plaque formation, destabilization, and rupture.
  • miRNAs impact endothelial cell function and both innate and adaptive immune systems in vascular aging.

Conclusions:

  • miRNAs are central players in the pathogenesis of atherosclerosis, particularly in the context of aging.
  • Understanding miRNA mechanisms offers potential for novel therapeutic strategies.
  • Future research should focus on specific miRNA targets for clinical intervention in vascular aging and atherosclerosis.

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...

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
