Abstract

Substance abuse and other psychiatric diseases may share molecular pathology. In order to test this hypothesis, we examined the role of Disrupted In Schizophrenia 1 (DISC1), a psychiatric risk factor, in cocaine self-administration (SA). Cocaine SA significantly increased expression of DISC1 in the nucleus accumbens (NAc); while knockdown of DISC1 in NAc significantly increased cocaine SA and decreased phosphorylation of GSK-3β at Ser9 compared to scrambled shRNA. Our study provides the first mechanistic evidence of a critical role of DISC1 in drug-induced behavioral neuroadaptations and sheds more light at the shared molecular pathology of drug abuse and other major psychiatric disorders.
