摘要：Diabetic embryopathy is a diabetic complication, in which maternal hyperglycemia in early pregnancy causes birth defects in newborn infants. Under maternal diabetic conditions, hyperglycemia disturbs intracellular molecular activities and organelles functions. These include protein misfolding in the endoplasmic reticulum (ER), overproduction of reactive oxygen species (ROS) in mitochondria, and high levels of nitric oxide (NO). The resultant ER, oxidative, and nitrosative stresses activate apoptotic machinery to cause cell death in the embryo, ultimately resulting in developmental malformations. Based on the basic research data, efforts have been made to develop interventional strategies to alleviate the stress conditions and to reduce embryonic malformations. One of the challenges in birth defect prevention is to identify effective and safe agents to be used in pregnancy. One approach is to search and characterize naturally occurring phytochemicals, including flavonoids, curcuminoids and stilbenoids, for use in prevention of diabetic embryopathy.
