The influence of maternal diet on offspring development and liver metabolism
Almond, Kayleigh (2011) The influence of maternal diet on offspring development and liver metabolism. PhD thesis, University of Nottingham.
Altering maternal nutrition affects fetal development and can have long-lasting effects on the offspring, potentially predisposing them to later metabolic disease. These effects can occur without affecting birth weight, although small for date offspring appear to be at increased risk. One mechanism linking changes in the maternal environment to an increased risk of later disease is enhanced exposure to glucocorticoids (GC). Tissue sensitivity to cortisol is regulated, in part, by the GC receptor (GR) and 11-beta-hydroxysteroid dehydrogenase (11βHSD) types 1 and 2. Several studies have shown the effects of maternal nutrient restriction on the programming of GC action in the offspring, however, dietary excess is far more characteristic of the diets consumed by contemporary pregnant women. The aim of this thesis was to provide a novel insight into the effects of moderate changes in the macronutrient ratio, within the maternal diet fed to pigs (whilst maintaining energy content), on offspring growth, development and liver metabolism until adolescence.
