Abstract: Major depression is becoming one of the most prevalent  forms of psychiatric disorders. However, the mechanisms of major  depression are still not well-understood. Most antidepressants are only  effective in some patients and produce some serious side effects. Animal  models of depression are therefore essential to unravel the mechanisms  of depression and to develop novel therapeutic strategies. Our previous  studies showed that Abelson helper integration site-1 (Ahi1) deficiency  causes depression-like behaviors in mice. In this study, we  characterized the biochemical and behavioral changes in Ahi1 knockout  (KO) mice. In Ahi1 KO mice, neurotransmitters including serotonin and  dopamine were significantly decreased in different brain regions.  However, glutamate and GABA levels were not affected by Ahi1 deficiency.  The antidepressant imipramine attenuated depressive behaviors and  partially restored brain serotonin level in Ahi1 KO mice. Our findings  suggest that Ahi1 KO mice can be used for studying the mechanisms of  depression and screening therapeutic targets.
