Epigenetics of cocaine addiction placebo, it was found that HDAC inhibitors had a significant effect on lowering cocaine-seeking behavior. This also suggests an epigenetic mechanism involved in HDAC chromatin regulation. The data is crucial to proving the hypothesis that trichostatin A can remodel chromatin structure and prevent behavioral changes following cocaine exposure. Tests also revealed that HDAC inhibitor administration can not only prevent addiction, but also helps reduce the risk of a relapse in cocaine addicts in the rat model system. As the previous findings suggest, chronic cocaine use caused both alterations in the chromatin remodeling activity of HDACs and drug seeking behavior. Renthal
