Abstract

We have used an ultraviolet light cross-linking and immunoadsorption assay to demonstrate that histones H1 and H2B are bound to the repressed MMTV promoter. Hormone activation results in reduced H1 content with little or no change in H2B. High resolution analysis of the glucocorticoid-inducible DNaseI hypersensitive region demonstrates an NF-1 footprint as well as specific sites of enhanced cleavage on nucleosome B and in the nucleosome B/nucleosome A linker. These results are consistent with a model in which binding of the glucocorticoid receptor to glucocorticoid regulatory elements on the surface of nucleosome B induces a chromatin transition that is necessary for transcription factor (NF-1 and TFIID) recruitment to the MMTV promoter. We hypothesize that association of histone H1 with important cis-elements on the promoter masks these sites, and glucocorticoid-induced displacement of H1 is necessary to expose factor binding sites at the 3' edge of nucleosome B, in the nucleosome B/nucleosome A linker and at the 5' edge of nucleosome A.

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.
