Maternal diet: a modulator for epigenomic regulation during development in nonhuman primates and humans.


ABSTRACT: The importance of diet in health and disease has been well characterized in the past decades. Although the earlier focus of diet research was in the context of undernutrition and the importance of adequate nutrient intake to prevent malnutrition, in the current era of epidemic obesity the focus of our efforts has evolved toward understanding the effects of excess caloric intake. The current surge in childhood obesity rates suggests a correlation of maternal metabolic syndrome and obesity with programming of the fetal epigenome for metabolic diseases later in life. Alterations of the fetal genome, epigenome and metabolome have been well documented in cases of maternal malnutrition, including both overnutrition and undernutrition. It is of great interest and importance to understand how these divergent maternal factors regulate/program the fetus for metabolic diseases, and we and others have observed that epigenetic modifications to the fetal and placental epigenome accompany these reprogramming events. The following review summarizes recent studies on the effects of maternal diet and obesity on fetal epigenetics contributing to adult diseases later in life by taking advantage of state-of-the-art genomic, epigenomic and metagenomic techniques in nonhuman primate model systems.
