Abstract

Enhanced anxiety is a salient feature of a number of psychiatric disorders including anxiety disorders, trauma-related disorders and depression. Although aberrant expression of various genes has been detected in patients suffering from persistent high anxiety as well as in high anxiety rodent models, the molecular mechanisms responsible for altered transcription regulation have been poorly addressed. Transcription regulation intimately involves the contribution of chromatin modifying processes, such as histone modification and ATP-dependent chromatin remodeling, yet their role in pathological anxiety is not known. Here, we investigated for the first time if altered levels of several ATP-dependent chromatin remodeling factors (ChRFs) and histone deacetylases (HDACs) may be linked to high trait anxiety in mice. While we found protein levels of the ChRFs SNF2H, ATRX, CHD1, CHD3 and CHD5 and of HDACs 1-3 and 6 to be similar in most of the tested brain areas of mice with high (HAB) versus normal (NAB) anxiety-related behavior, we observed distinctly altered regulation of SNF2H in the amygdala, and of CHD3 and CHD5 in the ventral hippocampus. In particular, CHD3 and CHD5 exhibited altered expression of protein but not of mRNA in HAB mice. Since both proteins are components of NuRD-like complexes, these results may indicate an impaired equilibrium between different NuRD-like complexes in the ventral hippocampus. Overall, our data provide novel evidence for localized differences of specific ATP-dependent chromatin remodeling factors in mice with high trait anxiety that may ultimately contribute to altered transcriptional programs resulting in the manifestation of pathological anxiety.

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.
