Abstract

Scope: Early life nutrition has long-lasting influence in adults through key mediators that modulate epigenetic states, although the determinants involved that underlie this response remain controversial. Because of the similarities between metabolic, physiological, and endocrine changes and those occurring in human type 2 diabetes, we studied the interaction of diet during pregnancy regulating RNA adenosine methylation (N6-methyladenosine [m6A]) and the transcriptome in Psammomys obesus. Methods and results: Breeding pairs were randomly allocated standard diet (total digestible energy 18 MJ kg−1) or low-fat diet (15 MJ kg−1). Offspring were weaned onto the low-fat diet at 4 weeks of age and..
