in heroin-conditioned place preference paradigm. Heroin could dose-dependently increase
histone H3 phosphoacetylation specifically in the NAc and could enhance heroin place
preference. Injection of trichostatin A into the NAc significantly augmented heroin-induced
histone H3 phosphoacetylation and enhanced heroin place preference. Conversely,
injection of MK-801 into the NAc attenuated histone H3 phosphoacetylation and reduced …
