Analysis of full-term placentas exposed to maternal cigarette smoke. The placenta produces and metabolizes steroids and xenobiotics. Results provide insight into the effects of maternal cigarette smoking on the placenta at term, with a focus on xenobiotic- and steroid-metabolizing genes.

(Submitter supplied) Smoking in pregnancy increases a woman's risk of preterm delivery resulting in serious health problems during the newborn period, chronic lifelong disabilities (such as cerebral palsy, mental retardation and learning problems), and even death. Further, smoking women have placental problems such as placenta previa (a low-lying placenta that covers part or all of the opening of the uterus), placental abruption (in which the placenta peels away, partially or almost completely before delivery) often resulting in bleeding during delivery. more...

(Submitter supplied) Maternal smoking has a severe negative effect on all stages of pregnancy that in consequence impairs fetal growth and development. Tobacco smoke-related defects are well established at the clinical level; however, little is known about molecular mechanisms underlying these pathological conditions. We thus employed a genomic approach to determine transcriptome alterations induced by maternal smoking in pregnancy. more...
