Abstract:
Chronic wounds are a major burden to overall healthcare cost and patient morbidity. Chronic wounds affect a large portion of the US, and billions of healthcare dollars are spent in their treatment and management. microRNAs (miRNAs) are small, noncoding double-stranded RNAs that post-transcriptionally downregulate the expression of protein-coding genes. Studies have identified miRNAs involved in all three phases of wound healing including inflammation, proliferation, and remodeling. Some miRNAs have been demonstrated in vitro with primary keratinocyte wound healing model and in vivo with mouse wound healing model through regulation of miRNA expression to affect the wound healing process. This review updates the current miRNAs involved in wound healing and discusses the future therapeutic implications and research directions.
Insights
MicroRNAs (miRNAs) are key regulators of chronic wound healing. This review explores their role in inflammation, proliferation, and remodeling, highlighting therapeutic potential for better wound management.
Area of Science:
- Biochemistry
- Molecular Biology
- Regenerative Medicine
Background:
- Chronic wounds represent a significant healthcare burden, impacting patient morbidity and incurring substantial treatment costs.
- MicroRNAs (miRNAs) are small, noncoding RNAs that regulate gene expression post-transcriptionally.
- These miRNAs play crucial roles in the distinct phases of wound healing: inflammation, proliferation, and remodeling.
Purpose of the Study:
- To review the current understanding of microRNAs involved in the wound healing process.
- To discuss the therapeutic implications of targeting miRNAs for chronic wound treatment.
- To identify future research directions in miRNA-based wound healing therapies.
Main Methods:
- Literature review of studies investigating microRNAs in wound healing.
- Analysis of in vitro models using primary keratinocytes.
- Examination of in vivo studies utilizing mouse wound healing models.
Main Results:
- Specific miRNAs have been identified that influence all three phases of wound healing.
- Modulation of miRNA expression has been shown to impact the speed and efficacy of wound closure.
- Evidence supports the involvement of miRNAs in regulating key cellular processes during healing.
Conclusions:
- MicroRNAs are critical regulators of chronic wound healing.
