Clinical Report: Transcriptomic Analysis of a Diabetic Porcine Model for Wound Healing
Overview
This study characterizes a diabetic porcine model of full-thickness wound healing, revealing significant delays in wound closure and distinct transcriptional profiles compared to non-diabetic wounds. The study identifies pathways involved in metabolism, inflammation, and oxidative stress associated with impaired wound healing in diabetes.
Background
Diabetic foot ulcers (DFUs) are associated with high rates of lower limb amputation and increased mortality. The DFU microenvironment is characterized by inflammation, metabolic dysfunction, and oxidative stress, complicating healing. Understanding wound healing mechanisms in relevant animal models is essential for developing effective therapies.
Data Highlights
No numerical data available.
Key Findings
Diabetes induced in Yucatan minipigs via STZ resulted in significant delays in wound closure and contraction.
Diabetic wounds exhibited reduced collagen and granulation tissue deposition compared to non-diabetic wounds.
Bulk RNA sequencing revealed 1015 differentially expressed genes between diabetic and non-diabetic wounds.
Key dysregulated pathways included those related to metabolism, inflammation, and oxidative stress.
Immune dysregulation was evident, with upregulated genes associated with innate and adaptive immunity.
Clinical Implications
Understanding these pathways may lead to improved healing outcomes.
Conclusion
This study provides insights into the transcriptional changes associated with impaired wound healing in diabetes.
