CRACKing the histone code: Cocaine's effects on chromatin structure and function

Abstract

Epigenetics, the nongenetic component of how chromatin structure influences gene expression, is amazingly complex, and linking how environmental stimuli can influence epigenetic 'gene programs' in specific nerve cells to ultimately control behavior is a seemingly insurmountable puzzle. Cocaine is a highly potent stimulus capable of influencing behavior for the lifetime of an organism. Not surprisingly, psychostimulant-induced epigenetic regulation of gene expression has thus been identified as key to understanding the pathology of addiction. In addition to identifying this essential role of epigenetics in addiction, several important concepts have emerged such as the importance of global, temporal, and spatial control of mRNA expression in considering any given histone modification's influence on a given gene. Adding to this complexity, one has to account for the cumulative influence of other epigenetic modifications on a gene's transcription in addition to the interplay between transcription factors and chromatin structure. This review highlights how bioinformatic, molecular, and behavioral studies on addiction provide new insight into these concepts and outlines two distinct psychostimulant-induced patterns of chromatin regulation which are thought to underlie unique programs of gene expression that contribute importantly to the addicted state.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Frequency of use is important, as some epigenetic changes occur with short but not repeated drug consumption, as is the case for hyperacetylation of histone H4 along the cFos gene promoter in the striatum, whereas hyperacetylation of histone H3 at BDNF promoters is seen only after repeated cocaine exposure.

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.
