Abstract

Eukaryotic transcription can be regulated over tens or even hundreds of kilobases. We show that such long-range gene regulation in vivo involves spatial interactions between transcriptional elements, with intervening chromatin looping out. The spatial organization of a 200 kb region spanning the murine beta-globin locus was analyzed in expressing erythroid and nonexpressing brain tissue. In brain, the globin cluster adopts a seemingly linear conformation. In erythroid cells the hypersensitive sites of the locus control region (LCR), located 40-60 kb away from the active genes, come in close spatial proximity with these genes. The intervening chromatin with inactive globin genes loops out. Moreover, two distant hypersensitive regions participate in these interactions. We propose that clustering of regulatory elements is key to creating and maintaining active chromatin domains and regulating transcription.

  • 3C confirmed that the LCR comes into close contact with active β-globin genes, whilst the intervening inactive genes are looped out.

    “3C confirmed that the LCR comes into close contact with active β-globin genes, whilst the intervening inactive genes are looped out [266].”
  • Two papers published in 2002 used different novel biochemical techniques to demonstrate that the β-globin LCR forms chromosomal loops with the active β-globin genes in vivo.

    “Two papers published in 2002 used different novel biochemical techniques to demonstrate that the β-globin LCR forms chromosomal loops with the active β-globin genes in vivo.”
  • Enhancer-promoter looping occurred in erythroid cells, in which the β-globin genes are expressed, but not in brain cells, in which they are not.

    “Enhancer–promoter looping occurred in erythroid cells, in which the β-globin genes are expressed, but not in brain cells, in which they are not [266].”
  • Remote enhancers in the mouse β-globin gene domain form a single complex to which the genes that need to be activated are recruited.

    “It has been shown that remote enhancers in the mouse β-globin gene domain form a single complex to which the genes that need to be activated are recruited [32].”

  • Active enhancers are often in physical proximity to the promoters they activate, regardless of the genomic distances between these enhancers and promoters.

    “First, it was shown that active enhancers are often in physical proximity to the promoters they activate, regardless of the genomic distances between these enhancers and promoters [32,33,34].”

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.
