Delayed effects of experimental maternal diabetes on plasma cholesterol level and vascular prostacyclin synthesis in the offspring

The effect of streptozotocin-induced diabetes during pregnancy in rats on prostacyclin synthesis in aorta and heart of offsprings was investigated. Although the aortic and heart syntheses of 6-keto-PGF1 alpha in the offsprings of diabetic rats were not altered at birth, a significant rise in aorta and a decrease in the heart were evident at weaning. At weaning, offsprings of diabetic rats also show a significant rise in plasma cholesterol. These studies show that maternal diabetes might cause effects in the offspring which might become evident in later life.
