Three-dimensional super-resolution microscopy of the inactive X chromosome territory reveals a collapse of its active nuclear compartment harboring distinct Xist RNA fociSpringer Science and Business Media LLC - Tập 7 - Trang 1-27 - 2014

A Xist RNA decorated Barr body is the structural hallmark of the compacted
inactive X territory in female mammals. Using super-resolution three-dimensional
structured illumination microscopy (3D-SIM) and quantitative image analysis, we
compared its ultrastructure with active chromosome territories (CTs) in human
and mouse somatic cells, and explored the spatio-temporal process of Barr body

Activation of the alpha-globin gene expression correlates with dramatic upregulation of nearby non-globin genes and changes in local and large-scale chromatin spatial structureSpringer Science and Business Media LLC - Tập 10 - Trang 1-19 - 2017

In homeotherms, the alpha-globin gene clusters are located within permanently
open genome regions enriched in housekeeping genes. Terminal erythroid
differentiation results in dramatic upregulation of alpha-globin genes making
their expression comparable to the rRNA transcriptional output. Little is known
about the influence of the erythroid-specific alpha-globin gene transcription

A combined HM-PCR/SNuPE method for high sensitive detection of rare DNA methylationSpringer Science and Business Media LLC - Tập 3 - Trang 1-8 - 2010

DNA methylation changes are widely used as early molecular markers in cancer
detection. Sensitive detection and classification of rare methylation changes in
DNA extracted from circulating body fluids or complex tissue samples is crucial
for the understanding of tumor etiology, clinical diagnosis and treatment. In
this paper, we describe a combined method to monitor the presence of methylated

The fungus Neurospora crassa displays telomeric silencing mediated by multiple sirtuins and by methylation of histone H3 lysine 9Springer Science and Business Media LLC - Tập 1 Số 1 - 2008

Abstract Background Silencing of genes inserted near telomeres provides a model
to investigate the function of heterochromatin. We initiated a study of
telomeric silencing in Neurospora crassa, a fungus that sports DNA methylation,
unlike most other organisms in which telomeric silencing has been characterized.
Results The selectable marker, hph, was inserted at the subtelomere of Linkage

Application of dual reading domains as novel reagents in chromatin biology reveals a new H3K9me3 and H3K36me2/3 bivalent chromatin stateSpringer Science and Business Media LLC - Tập 10 - Trang 1-19 - 2017

Histone post-translational modifications (PTMs) play central roles in
chromatin-templated processes. Combinations of two or more histone PTMs form
unique interfaces for readout and recruitment of chromatin interacting
complexes, but the genome-wide mapping of coexisting histone PTMs remains an
experimentally difficult task. We introduce here a novel type of affinity
reagents consisting of two fuse... hiện toàn bộ
