Screening of drug for attention deficit hyperactive disorder by using GIT1 knock-out mice as a novel ADHD mouse model

Abstract

Provided is a method of using any mammal except humans, in particular, a mammal as an attention deficit hyperactivity disorder model, wherein genes of G protein-coupled receptor kinase interacting protein 1 (GIT1) as a neuronal synapse protein in the brain are knocked out from the mammal. In addition, disclosed is analysis of GIT1 knock-out mice in aspects of molecular biology, cellular biology, electrical biology and animal behavior and, more particularly, a screening method of novel drug, wherein excessive behavior as an attention deficit hyperactive disorder as well as recovery of theta wave in the frontal lobe are observed by administering a candidate material of the drug, thereby inducing recovery of the attention deficit hyperactivity disorder.
