Abstract

To further define the function of the oxytocin receptor (OXTR) in vivo, we generated mice deficient in the Oxtr gene (Oxtr-/-). Oxtr-/- mice had no obvious deficits in fertility or sexual behaviour, but displayed several aberrations in social behaviours, including male aggression, and mother-offspring interaction. In addition, they showed novel physiological defects including obesity, and dysfunction in body temperature control when exposed to cold. We review here our new findings with Oxtr-/- mice, and introduce newly generated Oxtr-Venus knockin mice as a potential tool for examining molecular physiology of Oxtr-neurons.
