Summary
Cell-free non-coding RNAs in biofluids show promise as non-invasive biomarkers for chronic wound healing. These molecules can help predict outcomes and guide personalized treatments for conditions like diabetic foot ulcers.
Area of Science:
- Biomolecular Medicine
- Molecular Diagnostics
- Regenerative Medicine
Background:
- Chronic non-healing wounds pose significant clinical and economic challenges.
- Current biomarkers for predicting wound healing are limited, hindering personalized patient care.
- Cell-free nucleic acids (cfNAs) offer a non-invasive window into wound pathophysiology.
Purpose of the Study:
- To review the challenges in current wound healing biomarker development.
- To explore the potential of cell-free non-coding RNAs as biomarkers for chronic wounds.
- To highlight the utility of microRNAs, long non-coding RNAs, and circular RNAs in wound assessment.
Main Methods:
- Literature review focusing on cell-free RNAs in chronic wound healing.
- Survey of microRNAs, long non-coding RNAs, and circular RNAs in wound biomarker research.
- Analysis of extracellular RNAs for disease signature identification.
Main Results:
- Cell-free RNAs, including non-coding RNAs, are detectable in biofluids like serum and plasma.
- These RNAs provide dynamic molecular insights into wound healing processes.
- Specific non-coding RNA profiles correlate with wound severity and healing potential.
Conclusions:
- Extracellular non-coding RNAs represent a rich resource for developing novel wound healing biomarkers.
- These biomarkers can aid in stratifying wound severity and predicting healing trajectories.
- Non-invasive cfRNA profiling may guide personalized therapeutic interventions for chronic wounds.
