Abnormal angiogenesis in diabetes mellitus

Area of Science:

• Endocrinology
• Vascular Biology
• Diabetology

Background:

• Diabetes mellitus is associated with widespread organ damage, often linked to hyperglycemia.
• Abnormalities in angiogenesis (new blood vessel formation) are increasingly recognized as a key factor in diabetic complications.
• Existing diabetes management primarily targets blood glucose control, potentially overlooking angiogenic factors.

Purpose of the Study:

• To review the clinical manifestations of aberrant angiogenesis in diabetes mellitus.
• To elucidate the molecular mechanisms underlying abnormal angiogenesis in diabetic patients.
• To discuss potential therapeutic strategies for managing angiogenesis-related diabetic complications.

Main Methods:

• This is a review article, synthesizing existing literature.
• The review examines clinical observations and experimental findings related to angiogenesis in diabetes.
• Molecular pathways and pathogenetic mechanisms are analyzed based on published research.

Main Results:

• Diabetic patients exhibit vascular abnormalities in the retina, kidneys, and fetus.
• Impaired wound healing, heightened transplant rejection risk, and poor coronary collateral formation are linked to aberrant angiogenesis.
• Excessive and insufficient angiogenesis can paradoxically occur in different organs within the same diabetic individual.

Conclusions:

• Aberrant angiogenesis is a significant contributor to the pathogenesis of numerous diabetic complications.
• Understanding the molecular basis of abnormal angiogenesis is crucial for developing targeted therapies.
• Future treatments may focus on modulating angiogenic processes to mitigate long-term diabetic sequelae.
