Abstract:
Wound healing is a complex biological process that is impaired under diabetes conditions. Chronic non-healing wounds in diabetes are some of the most expensive healthcare expenditures worldwide. Early diagnosis and efficacious treatment strategies are needed. microRNAs (miRNAs), a class of 18-25 nucleotide long RNAs, are important regulatory molecules involved in gene expression regulation and in the repression of translation, controlling protein expression in health and disease. Recently, miRNAs have emerged as critical players in impaired wound healing and could be targets for potential therapies for non-healing wounds. Here, we review and discuss the mechanistic background of miRNA actions in chronic wounds that can shed the light on their utilization as specific wound healing biomarkers.
Insights
Diabetes impairs wound healing, leading to costly chronic wounds. MicroRNAs (miRNAs) are key regulators in this process and show promise as diagnostic biomarkers and therapeutic targets for improved diabetes wound care.
Area of Science:
- Biomedical Science
- Molecular Biology
- Endocrinology
Background:
- Wound healing is a complex biological process significantly impaired in diabetic patients.
- Chronic non-healing diabetic wounds represent a major global healthcare cost.
- Current diagnostic and treatment strategies for these wounds are insufficient.
Purpose of the Study:
- To review the mechanistic role of microRNAs (miRNAs) in impaired wound healing.
- To discuss the potential of miRNAs as biomarkers for chronic wounds.
- To explore miRNAs as therapeutic targets for non-healing diabetic wounds.
Main Methods:
- Literature review and synthesis of existing research on miRNAs in wound healing.
- Analysis of the regulatory functions of miRNAs in gene and protein expression.
- Discussion of the implications of miRNA dysregulation in diabetes-associated wound complications.
Main Results:
- MicroRNAs (miRNAs) are critical regulatory molecules involved in gene expression.
- miRNAs play significant roles in the pathophysiology of impaired wound healing in diabetes.
- Dysregulated miRNA expression contributes to chronic non-healing wounds.
Conclusions:
- MicroRNAs (miRNAs) are emerging as crucial factors in the impaired wound healing observed in diabetes.
- miRNAs hold potential as specific biomarkers for early diagnosis of chronic wounds.
- Targeting miRNAs may offer novel therapeutic strategies for treating non-healing diabetic wounds.
