Prenatal nicotine exposure can lead to cardiac function reprogramming in adult offspring

WASHINGTON -- At least 11 percent of American women smoke during pregnancy. The negative effects of nicotine exposure to their fetuses and newborns are significant. A 2004 report by the Surgeon General, for example, found that women who smoked during pregnancy had children who were at a three times higher risk for SIDS than were the offspring of non-smokers. Now, a new study using laboratory rats, provides strong evidence that the effects of maternal smoking during the prenatal period of life can lead to cardiac vascular dysfunction beyond the formative years -- and into adulthood.

The finding is part of a new study entitled Effect of Prenatal Nicotine Exposure on Coronary Flow in Adult Offspring: A Gender Dichotomy. It was conducted by Daliao Xiao, Jennifer Lawrence, Shumei Yang, and Lubo Zhang, all of the Center for Perinatal Biology, Loma Linda University, School of Medicine, Loma Linda, and the Department of Chemistry and Biochemistry, California State University, San Bernardino, CA Dr. Zhang will lead a discussion of the findings at the 120th annual meeting of the American Physiological Society (APS; www.the-APS.org), being held as part of the Experimental Biology (EB 07) meeting. More than 12,000 scientists and researchers are attending the conference, being held April 28-May 2, 2007 at the Washington, DC Convention Center.

Summary of Methodology

Nicotine (2.1 mg/d) was administered via osmotic minipumps placed under the skin throughout gestation and up to ten days after delivery. Hearts were isolated from three month old male and female offspring, and subjected to 25-minutes of mechanical obstruction of blood flow ischemia followed by 60-minutes of myocardial impairment caused by opening of the blockage. Pulmonary artery discharge was collected as an index of coronary flow (ml/min/g heart wet weight).
