Mesoscale Modeling Reveals Hierarchical Looping of Chromatin Fibers Near Gene Regulatory Elements.

While it is well-recognized that chromatin loops play an important role in gene regulation, structural details regarding higher order chromatin loops are only emerging. Here we present a systematic study of restrained chromatin loops ranging from 25 to 427 nucleosomes (fibers of 5-80 Kb DNA in length), mimicking gene elements studied by 3C contact data. We find that hierarchical looping represe...

Linking Chromatin Fibers to Gene Folding by Hierarchical Looping.

While much is known about DNA structure on the basepair level, this scale represents only a fraction of the structural levels involved in folding the genomic material. With recent advances in experimental and theoretical techniques, a variety of structures have been observed on the fiber, gene, and chromosome levels of genome organization. Here we view chromatin architecture from nucleosomes an...

Cell-type-specific long-range looping interactions identify distant regulatory elements of the CFTR gene

Identification of regulatory elements and their target genes is complicated by the fact that regulatory elements can act over large genomic distances. Identification of long-range acting elements is particularly important in the case of disease genes as mutations in these elements can result in human disease. It is becoming increasingly clear that long-range control of gene expression is facili...

Pharmacologic control of chromatin looping

S ickle cell disease (SCD) and b-thalassemia are widespread genetic disorders that result from inherited mutations in the adultb-globin gene. An important aspect of SCD and b-thalassemia is that diseasecausing mutations affect the adult b-globin gene but leave intact its fetal counterparts Ggand Ag-globin, a point that explains why SCD and b-thalassemia patients first experience major symptoms ...

FAIRE (Formaldehyde-Assisted Isolation of Regulatory Elements) isolates active regulatory elements from human chromatin.

DNA segments that actively regulate transcription in vivo are typically characterized by eviction of nucleosomes from chromatin and are experimentally identified by their hypersensitivity to nucleases. Here we demonstrate a simple procedure for the isolation of nucleosome-depleted DNA from human chromatin, termed FAIRE (Formaldehyde-Assisted Isolation of Regulatory Elements). To perform FAIRE, ...
