Exposure to a choline-deficient diet during pregnancy and lactation alters the liver transcriptome profile in offspring of dams with fatty liver.
Background & aims: The developmental origin of health and disease hypothesis shows that early adverse exposures can have lifelong health effects. Thus, the aim of this study was to analyze the impact of choline intake during pregnancy and/or lactation on gene expression profiles in the liver of 24-day-old male rat offspring from dams with non-alcoholic fatty liver disease (NAFLD).
Methods: Phenotypic characteristic, histological examination and global transcriptome pattern of liver tissue specimens obtained from offspring of dams suffering from fatty liver, provided with proper choline intake during pregnancy and lactation (NN), fed a choline-deficient diet during both periods (DD), deprived of choline only during pregnancy (DN), or only during lactation (ND), was performed. The global gene expression profile was analyzed by using microarray approach (Affymetrix® Rat Gene 2.1 ST Array Strip). The relative expression of selected genes was validated by real-time polymerase chain reaction (qPCR).
Results: The histological examination of rat liver sections indicated alternations typical for fatty liver in all analyzed groups with increased progression among groups deprived of choline. Choline deficiency in the maternal diet was associated with changes in body mass and composition but not with biochemical marker levels, except for the high density lipoprotein fraction of cholesterol (HDL). Enhanced expression of genes involved in oxidative stress, cell proliferation, activation of catabolic processes related to hepatocyte dysfunction and cell membrane composition were simultaneously observed in all choline-deficient groups.
Conclusions: An adequate amount of choline in the diet of a mother with fatty liver during pregnancy and/or lactation can regulate gene expression in the offspring's liver and contribute to a milder stage of the disease in the progeny. Moreover, proper choline supply during the postpartum period is as crucial as during the prenatal period.
期刊介绍：
Clinical Nutrition ESPEN is an electronic-only journal and is an official publication of the European Society for Clinical Nutrition and Metabolism (ESPEN). Nutrition and nutritional care have gained wide clinical and scientific interest during the past decades. The increasing knowledge of metabolic disturbances and nutritional assessment in chronic and acute diseases has stimulated rapid advances in design, development and clinical application of nutritional support. The aims of ESPEN are to encourage the rapid diffusion of knowledge and its application in the field of clinical nutrition and metabolism. Published bimonthly, Clinical Nutrition ESPEN focuses on publishing articles on the relationship between nutrition and disease in the setting of basic science and clinical practice. Clinical Nutrition ESPEN is available to all members of ESPEN and to all subscribers of Clinical Nutrition.
