Maternal obesity and fetal metabolic programming: a fertile epigenetic soil.
The incidence of obesity and overweight has reached epidemic levels in the United States and developed countries worldwide. Even more alarming is the increasing prevalence of metabolic diseases in younger children and adolescents. Infants born to obese, overweight, and diabetic mothers (even when normal weight) have increased adiposity and are at increased risk of later metabolic disease. In ad...
متن کاملEpigenetic programming of stress responses through variations in maternal care.
Early life experiences shape an individual's physical and mental health across the lifespan. Not surprisingly, an upbringing that is associated with adversity can produce detrimental effects on health. A central theme that arises from studies in human and nonhuman species is that the effects of adversity are mediated by the interactions between a mother and her young. In this review we describe...
متن کاملIron status of suckling rats as influenced by maternal diet during gestation and lactation.
1. Two experiments are reported. In Expt 1, pregnant Sprague-Dawley rats (200-220 g) were given purified diets containing 35, 75, 150 or 300 mg Fe/kg throughout gestation and lactation. In Expt 2, the levels of Fe given were 250 and 300 mg/kg diet. 2. Litters were standardized at birth to contain seven pups. On day 20 of lactation blood, milk, spleen and liver were collected for Fe analysis. 3....
متن کاملPerturbation of epigenetic status by toxicants.
It is becoming increasingly apparent that toxicant-induced changes in epigenetic status, particularly DNA methylation patterns, may play a role in some mechanisms of toxicity. Here, we discuss briefly the evidence that alterations in DNA methylation accompany, and may even promote, carcinogenesis induced by non-genotoxic chemicals. We also address recent findings indicating that the availabilit...
متن کاملP-81: Distinct Epigenetic Status of Fully Grown and Growing Oocytes Selected by BCB Staining
Background: Since the sheep ‘Dolly’ was successfully cloned by somatic cell nuclear transfer (SCNT), the inefficiency of SCNT cloning and abnormality of cloned animals have been a focus of considerable controversy. Oocyte quality has been shown to contribute to poor somatic cloning and cell reprogramming efficiency with many factors affecting oocyte quality and developmental potential. It has b...
