Editorial: Nutrigenomics: omics of maternal nutrition and foetal programming

Résumé

The impact of nutrition on maternal and fetal health is enormous and can limit the newborns productive 12 performance as well as metabolic functions such those related to lipids and carbohydrates. Maternal 13 nutrition has been taken to the molecular level, where the interplay between maternal functional 14 nutrients uptake and fetal-Omics has brought to us several key pathways to better understand the 15 maternal nutrigenomics (effect of nutrition on gene expression at different tissue levels analyzed pancreatic islets from male progeny of rats at postnatal days from juveniles and young adults. 38 Specifically, they analyzed the expression of genes involved in β-cell function and DNA methylation. 39In general, their study showed that lack of dietary protein during gestation alters genes related to β-cell 40 function in male juvenile offspring while decreasing DNA methylation. Interestingly, this process
