Increased apoptosis during neonatal brain development underlies the adult behavioral deficits seen in mice lacking a functional paternally expressed gene 3 (Peg3).

Abstract excerpt

Inactivation of the maternally imprinted, paternally expressed gene 3 (Peg3) induces deficits in olfactory function, sexual and maternal behaviors, oxytocin neuron number, metabolic homeostasis and growth. Peg3 is expressed in a number of developing hypothalamic and basal forebrain structures and is a component of the P53 apoptosis pathway. Peg3 inactivation in neuronal cell culture lines inhibits P53 mediated...
