Evidence for nucleosome depletion at active regulatory regions genome-wide

Abstract

The identification of nuclease-hypersensitive sites in an active globin gene and in the 5' regions of fruit fly heat shock genes first suggested that chromatin changes accompany gene regulation in vivo. Here we present evidence that the basic repeating units of eukaryotic chromatin, nucleosomes, are depleted from active regulatory elements throughout the Saccharomyces cerevisiae genome in vivo. We found that during rapid mitotic growth, the level of nucleosome occupancy is inversely proportional to the transcriptional initiation rate at the promoter. We also observed a partial loss of histone H3 and H4 tetramers from the coding regions of the most heavily transcribed genes. Alterations in the global transcriptional program caused by heat shock or a change in carbon source resulted in an increased nucleosome occupancy at repressed promoters, and a decreased nucleosome occupancy at promoters that became active. Nuclease-hypersensitive sites occur in species from yeast to humans and result from chromatin perturbation. Given the conservation of sequence and function among components of both chromatin and the transcriptional machinery, nucleosome depletion at promoters may be a fundamental feature of eukaryotic transcriptional regulation.

Claims other papers make about this one

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

  • Genomic sequences with high chromatin accessibility are typically bound by one or more TFs, although the identity of the TF is not directly measured by the experiment.

    “DNA is typically accessible in a highly local and cell-type-specific manner, and in particular, genomic sequences with high accessibility are typically bound by one or more TFs, although the identity of the TF is not directly measured by the experiment (Lee et al., 2004).”

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.
