Effect of a brain-penetrant selective estrogen receptor degrader (SERD) on binge drinking in female mice.

Alcohol Clin Exp Res 2022 May 17. Epub 2022 May 17.

Center for Alcohol Research in Epigenetics, Department of Psychiatry, University of Illinois at Chicago, Chicago, Illinois, USA.

Background: Greater circulating levels of the steroid hormone 17β-estradiol (E2) are associated with higher levels of binge drinking in women. In female mice, estrogen receptors in the ventral tegmental area, a dopaminergic region of the brain involved in the motivation to consume ethanol, regulate binge-like ethanol intake. We recently developed a brain-penetrant selective estrogen receptor degrader (SERD), YL3-122, that could be used to test the behavioral role of brain estrogen receptors. Read More

Targeted epigenomic editing ameliorates adult anxiety and excessive drinking after adolescent alcohol exposure.

Sci Adv 2022 05 4;8(18):eabn2748. Epub 2022 May 4.

Center for Alcohol Research in Epigenetics, Department of Psychiatry, University of Illinois at Chicago, Chicago, IL 60612, USA.

Adolescent binge drinking is a major risk factor for psychiatric disorders later in life including alcohol use disorder. Adolescent alcohol exposure induces epigenetic reprogramming at the enhancer region of the activity-regulated cytoskeleton-associated protein (Arc) immediate-early gene, known as synaptic activity response element (SARE), and decreases expression in the amygdala of both rodents and humans. The causal role of amygdalar epigenomic regulation at SARE in adult anxiety and drinking after adolescent alcohol exposure is unknown. Read More
