Summary
This study reveals microRNA (miRNA) profiles in human oral wound healing, identifying key molecules like SERPINB1 and IL-33 as potential therapeutic targets for faster, scar-free healing.
Area of Science:
- Molecular Biology
- Genomics
- Epigenetics
Background:
- MicroRNAs (miRNAs) regulate biological processes, but their role in human oral wound healing remains unexplored.
- Oral wound healing is distinct from skin healing, characterized by speed and minimal scarring.
Purpose of the Study:
- To investigate the miRNA expression profile in experimental human oral wounds.
- To perform an integrative analysis of mRNA and miRNA expression during oral wound healing.
Main Methods:
- Biopsies from human palatal wounds at 5 days of healing were analyzed using next-generation sequencing for miRNA and mRNA.
- Correlation and network analyses, real-time PCR (qPCR), and immunohistochemistry were employed.
Main Results:
- 169 significantly regulated precursor miRNAs, including 21 novel ones, were detected.
- Hsa-miR-223-3p and hsa-miR-124-3p were the most upregulated and downregulated miRNAs, respectively.
- SERPINB1 and IL33 were significantly upregulated and correlated with specific miRNAs, suggesting their involvement in healing.
Conclusions:
- This is the first report on the miRNome of human gingival healing with integrated miRNA/mRNA analysis.
- Findings provide novel insights into molecular mechanisms of oral wound healing.
- SERPINB1 and IL-33 are identified as potential therapeutic targets for enhancing oral wound healing.
