Fig. 1. Theoretical epigenetic mechanisms regulating ARC expression.

Fig. 1.

Alcohol consumption during adolescence increases addiction- and anxiety-like behavior in adulthood through epigenetic suppression of the Arc gene. Targeting dCas9-P300 to the Arc SARE restores Arc mRNA expression and reverses these behavioral phenotypes. In the future, novel therapeutics aimed at reversing the epigenetic suppression of Arc may be an effective treatment for patients with anxiety or substance use disorders. gRNA, guide RNA; TSS, transcription start site.
