Abstract

SUMMARY The removal of histone H3 lysine27 (H3K27) trimethylation mark is important for the robust induction of many cell type-specific genes during differentiation. Here we show that UTX, a H3K27 demethylase, acts as a critical switch to promote a cardiac-specific gene program. UTX-deficient ESCs failed to develop heart-like rhythmic contractions under a cardiac differentiation condition. UTX deficient mice show severe defects in heart development and embryonic lethality. We found that UTX is recruited to cardiac-specific enhancers by associating with core cardiac transcription factors and demethylates H3K27 residues in cardiac genes. In addition, UTX facilitates the recruitment of Brg1 to the cardiac-specific enhancers. Together, our data reveal key roles for UTX in a timely transition from poised to active chromatin in cardiac genes during heart development and a fundamental mechanism by which a H3K27 demethylase triggers tissue-specific chromatin changes.

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.
