Brain Chromatin Remodeling: A Novel Mechanism of Alcoholism
Open accessAbstract
The treatment of alcoholism requires the proper management of ethanol withdrawal symptoms, such as anxiety, to prevent further alcohol use and abuse. In this study, we investigated the potential role of brain chromatin remodeling, caused by histone modifications, in alcoholism. We found that the anxiolytic effects produced by acute alcohol were associated with a decrease in histone deacetylase (HDAC) activity and increases in acetylation of histones (H3 and H4), levels of CREB (cAMP-responsive element binding) binding protein (CBP), and neuropeptide Y (NPY) expression in the amygdaloid brain regions of rats. However, the anxiety-like behaviors during withdrawal after chronic alcohol exposure were associated with an increase in HDAC activity and decreases in acetylation of H3 and H4, and levels of both CBP and NPY in the amygdala. Blocking the observed increase in HDAC activity during alcohol withdrawal with the HDAC inhibitor, trichostatin A, rescued the deficits in H3 and H4 acetylation and NPY expression (mRNA and protein levels) in the amygdala (central and medial nucleus of amygdala) and prevented the development of alcohol withdrawal-related anxiety in rats as measured by the elevated plus maze and light/dark box exploration tests. These results reveal a novel role for amygdaloid chromatin remodeling in the process of alcohol addiction and further suggest that HDAC inhibitors may be potential therapeutic agents in treating alcohol withdrawal symptoms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
