    Tolerance to ethanol-induced anxiolysis promotes alcohol intake, thus contributing to alcohol use disorder development. Recent studies implicate histone deacetylase-mediated histone H3K9 deacetylation in regulating neuropeptide Y expression during rapid ethanol tolerance to the anxiolytic effects of ethanol. Furthermore, the histone
