New concepts in diabetic embryopathy

Area of Science:

• Reproductive biology
• Developmental toxicology
• Endocrinology

Background:

• Diabetes mellitus contributes to approximately 10% of fetal anomalies in pregnancies affected by the condition.
• Despite advanced perinatal care and glycemic control in developed nations, diabetic pregnancies exhibit elevated birth defect rates compared to the general population.

Purpose of the Study:

• To review the cellular and molecular mechanisms underlying diabetic embryopathy.
• To emphasize the need for translational research bridging animal studies and human clinical applications.

Main Methods:

• Review of animal models investigating diabetic embryopathy.
• Analysis of cellular activities (proliferation, apoptosis) and intracellular metabolic stress (nitrosative, oxidative, endoplasmic reticulum stress).

Main Results:

• Animal models demonstrate that major cellular activities and intracellular metabolic conditions are linked to diabetic embryopathy.
• Key factors include disruptions in proliferation, apoptosis, and various forms of cellular stress.

Conclusions:

• Diabetic embryopathy involves complex cellular and metabolic dysregulation.
• Translating findings from animal models to human clinical practice requires interdisciplinary collaboration among basic, preclinical, and clinical researchers.
