title: RhoGAP: the next big thing for small mice?
abstract: The size of an organism is determined by the number and size of its constituent cells. The insulin/IGF-1 signaling systems have been long recognized to play a critical role in the determination of body size. Now the generation of mice deficient for a RhoGAP suggests that this small G protein might also regulate the growth of animals.
