A
dolescent alcohol use is widely practiced at great personal and societal costs, including a prolonged vulnerability to
mood disorders and alcoholism. It is unknown how this environmental insult during development produces lasting
neurobiological changes, chronically predisposing one to psychopathology. Hypoxia inducible transcription factors (HIF)
regulate brain development and may mediate effects of repeated alcohol exposure during adolescence. Alcohols effect on
hypoxia pathways in the brain is unknown. This study aimed to characterize the changes in amygdaloid, hippocampal, and
hypothalamic HIF expression in response to adolescent intermittent ethanol (AIE) exposure in rats. A rat model of adolescent
binge-like ethanol exposure during postnatal days (PND) 28-41 was applied. Anxiety was measured using the light/dark box
assay at adolescence, PND 41 and 42 (1 and 24 hours after the final ethanol exposure), and at adulthood, PND 92. Increased
anxiety-like behaviors were detected in AIE adolescent rats during ethanol withdrawal and AIE adult rats. On the molecular
level, AIE induced amygdaloid, hippocampal, and hypothalamic HIF subunit 3a (HIF3a) mRNA expression when ethanol was
on board during adolescence. HIF3a expression increase was normalized upon withdrawal from ethanol. In AIE adult rats,
HIF3a expression was decreased in the amygdala, increased in the hippocampus, and showed no significant change in the
hypothalamus. These results suggest that HIF3a, via its regulatory actions on crucial target genes, may mediate ethanol-related
behaviors on the molecular level. Altered HIF3a expression in adulthood, in response to AIE, may underlie the AIE mediated
increased risk for alcoholism and anxiety-like behaviors in adulthood

Christina V Floreani completed her combined MD, PhD training from the University of Illinois at Chicago in 2011. She is currently a fourth year psychiatry resident at the University of Illinois at Chicago and is participating in research to investigate the molecular biology of alcoholism, with the ultimate goal of advancing our treatment options for alcoholism with or without comorbid psychiatric disorders.
