Attention-deficit hyperactivity disorder (ADHD) is a common neurobehavioural disorder. It is conceivable that Gamma aminobutyric acid (GABA) neurotransmission is implicated in the pathophysiology of ADHD. This study investigated the effect of GABA transporter 1 (GAT-1) on the anxiety-like behaviours and cognitive function in knockout mice.
In all, 20 adult male mice were divided into two groups: wild-type (WT) group and GAT-1−/− group. The open field test, elevated O-maze (EZM) and Morris water maze were used to evaluate behavioural traits relevant to ADHD.
Compared with WT mice, the GAT-1−/− mice travelled longer and displayed an enhanced kinematic velocity with the significant reduction of rest time in the open field test (p<0.05). The EZM showed that GAT-1−/− mice displayed a significant increase in total entries into the open sectors and the closed sectors compared with the WT mice. The WT mice showed shorter latencies after the training session (p<0.01), whereas the GAT-1−/− mice made no difference during probe test, the GAT-1−/− mice spent less time in the target quadrant (p<0.01).
Our results demonstrated that GAT-1−/− mice have phenotypes of hyperactivity, impaired sustained attention and learning deficiency, and the performance of GAT-1−/− mice is similar to ADHD symptoms. So, the study of the GAT-1−/− mice may provide new insights into the mechanisms and the discovery of novel therapeutics for the treatment of ADHD.
