Modeling substance abuse for applications in proteomics.
The ability to model aspects of human addictive behaviors in laboratory animals provides an important avenue for gaining insight into the biochemical alterations associated with drug intake and the identification of targets for medication development to treat addictive disorders. The intravenous self-administration procedure provides the means to model the reinforcing effects of abused drugs and to correlate biochemical alterations with drug reinforcement. In this chapter, we provide a detailed methodology for rodent intravenous self-administration and the isolation and preparation of proteins from dissected brain regions for Western blot analysis and high-throughput proteomic analysis. Examples of cocaine-induced alterations in the abundances of ionotropic glutamate receptor subunits in reinforcement-related brain regions are provided.
