FGF21 exerts beneficial metabolic effects on multiple tissues. Here the authors show that the Fgf21 gene is demethylated during the postnatal suckling period, creating an epigenetic memory that determines the responsiveness of the Fgf21 gene to inducers such as PPARα activators or fasting in adulthood.
