The cell biological and molecular cross-talks between different cell types such as adipocytes, endothelial cells, immune cells and intestinal epithelial cells are examined. Gene knock-out technology and feeding trials are applied for mouse studies. Human tissue samples and cells from our dietary inter- vention studies or women with gestational diabetes are analyzed. In recent years and in ongoing projects, we have been exploring the effects of nutri- tion (high-fat diets, n6- and n3 polyunsaturated fatty acids, methyl donor- rich diets) on cell differentiation and metabolic, inflammatory and vascu- lar processes as well as on gene regulatory mechanisms in liver, adipose tissues and intestine. In order to get better insights into the role of nutri- ents in fetal and metabolic programming and their underlying molecular and epigenetic control mechanisms (DNA methylation, microRNA, histone modifications) in different periods of life, we are analyzing the development, metabolism and physiology of adipose tissues, liver and placenta from fee- ding and intervention studies in mice and humans. Our research aims to gain a better understanding how nutrition contributes to and/or can prevent disease processes. Dr. Bernhard L.
