Neurobeachin, a promising target for use in the treatment of alcohol use disorder.

ABSTRACT: Hazardous, heavy drinking increases risk for developing alcohol use disorder (AUD), which affects ~7% of adult Americans. Thus, understanding the molecular mechanisms promoting risk for heavy drinking is essential to developing more effective AUD pharmacotherapies than those currently approved by the FDA. Using genome-wide bisulfate sequencing, we identified DNA methylation (DNAm) signals within the nucleus accumbens core (NAcC) that differentiate nonheavy and heavy ethanol-drinking rhesus macaques. One differentially DNAm region (D-DMR) located within the gene neurobeachin (NBEA), which promotes synaptic membrane protein trafficking, was hypermethylated in heavy drinking macaques. A parallel study identified a similar NBEA D-DMR in human NAcC that distinguished alcoholic and nonalcoholic
