Healing the diabetic wound: Unlocking the secrets of genes and pathways

Area of Science:

• Biomedical Science
• Molecular Biology
• Regenerative Medicine

Background:

• Diabetic wounds (DWs) are chronic sores complicated by infection, hypoxia, oxidative stress, and hyperglycemia.
• Impaired healing in DWs results from dysregulated cellular and molecular events across four phases: homeostasis, inflammation, proliferation, and remodeling.

Purpose of the Study:

• To review the pathogenesis, healing process, and involved genes and signaling pathways in diabetic wounds.
• To explore nanotechnology-based therapeutic strategies targeting these pathways.
• To cover clinical trials related to gene therapy for diabetic wounds.

Main Methods:

• Comprehensive literature review of diabetic wound pathogenesis.
• Analysis of key genes and signaling pathways (e.g., VEGF, TGF-β, NF-κB, MAPK) in wound healing.
• Examination of nanotechnology and gene therapy approaches for DW treatment.

Main Results:

• Diabetic wound healing is a complex process involving numerous dysregulated genes and signaling pathways.
• Nanotechnology offers promising strategies for targeted delivery and therapeutic intervention.
• Gene therapy clinical trials show potential for novel DW treatments.

Conclusions:

• Understanding the molecular mechanisms of DWs is crucial for developing effective therapies.
• Targeting specific genes and pathways with nanotechnology and gene therapy holds significant therapeutic promise.
• Further research and clinical trials are needed to optimize treatments for diabetic wounds.
