Maternal copper deficiency perpetuates altered vascular function in Sprague-Dawley rat offspring

Little is known about the consequences of maternal copper (Cu) deficiency on the vascular function of offspring or on perpetuation of vascular effects to a second generation. We examined vascular functional responses in mesenteric arteries from Cu-deficient Sprague-Dawley rat dams and from offspring directly exposed to maternal Cu deficiency during development and lactation and perpetuation of the effects in a second generation of offspring.

Preeclampsia: Exposing Future Cardiovascular Risk in Mothers and Their Children

There is an increased risk for future cardiovascular disease in women who have had preeclampsia. In infants born to mothers with preeclampsia, there is growing evidence of increased risk for both cardiovascular disease and preeclampsia. Epidemiologic and experimental data provide a strong link between intrauterine exposure to preeclampsia and subsequent risk for the development of cardiovascular disease in women.
 

Placental Insufficiency: Programming of Leptin Secretion, Blood Pressure, and Postnatal Growth in Two Generations of Sprague-Dawley Rats

Regulatory process may be altered in response to the intrauterine environment, leading to the development of altered growth trajectory and disease later in life. Previously, our lab reported reduced leptin levels in pregnant hypertensive Sprague-Dawley rat dams with placental insufficiency. The purposes of this study were to investigate the relationship between leptin levels, growth and hypertension in two generations of offspring exposed to placental insufficiency. Leptin levels were significantly different only at 12 weeks in female first generation offspring (p < 0.05).
