Insights

MicroRNAs (miRNAs) are key gene regulators. This review explores their role in chronic wound healing, suggesting potential as diagnostic and therapeutic targets for better patient outcomes.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Regenerative Medicine

Background:

  • Chronic wounds pose a significant clinical and economic burden.
  • MicroRNAs (miRNAs) are critical regulators of gene expression involved in numerous biological processes.
  • The specific role of miRNAs in chronic wound pathogenesis is not fully understood.

Purpose of the Study:

  • To review the existing literature on the function of miRNAs in wound healing.
  • To explore the potential involvement of miRNAs in the pathology of chronic wounds.
  • To discuss the prospective use of miRNAs in diagnostics and therapeutics for chronic wounds.

Main Methods:

  • Comprehensive literature review of studies investigating miRNAs and wound healing.
  • Analysis of miRNA involvement in epidermal differentiation, proliferation, inflammation, and angiogenesis.
  • Synthesis of current knowledge regarding miRNA dysregulation in chronic wounds.

Main Results:

  • miRNAs regulate key processes essential for normal wound healing, including cellular differentiation, proliferation, inflammation, and blood vessel formation.
  • Aberrant miRNA expression is implicated in the development and persistence of chronic wounds.
  • miRNAs show promise as biomarkers for assessing debridement needs and as therapeutic targets.

Conclusions:

  • miRNAs play a crucial role in both normal and pathological wound healing processes.
  • Understanding miRNA functions offers new avenues for diagnosing and treating chronic wounds.
  • miRNAs represent a promising frontier for novel therapeutic strategies in wound care.

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 ends...

Overview of Regeneration and Repair

Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Tissue Injury: Inflammation and Repair

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...
Regulation of Angiogenesis and Blood Supply01:24

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 hydroxylase and factor...
