Sub-optimal early life environments can influence life-long phenotypes, and epigenetic factors are thought to be key mediators of these effects. We show that early life protein restriction in mice induces a linear correlation between growth restriction and DNA methylation at a specific genetic variant of ribosomal DNA (rDNA), which is present long after exposure has ceased. Related effects are also found in models of maternal high-fat or obesogenic diets. Our work defines a unique example of gene-environment induced epigenetic dynamics, and establishes rDNA as the only known genomic target of nutritional insults found in mammalian and non-mammalian models.
