Reverse Phase-high-performance Liquid Chromatography (RP-HPLC) Analysis of Globin Chains from Human Erythroid Cells

open access: yesBio-Protocol, 2021
β-hemoglobinopathies are severe genetic disorders characterized either by the abnormal synthesis of the adult β-globin chains of the hemoglobin (Hb) tetramer (βS-globin chains) in sickle cell disease (SCD) or by the reduced β-globin production in β ...

Chromatin Hydrodynamics [PDF]

open access: yesBiophysical Journal, 2014
Following recent observations of large scale correlated motion of chromatin inside the nuclei of live differentiated cells, we present a hydrodynamic theory-the two-fluid model-in which the content of a nucleus is described as a chromatin solution with the nucleoplasm playing the role of the solvent and the chromatin fiber that of a solute. This system

Determinants of a transcriptionally competent environment at the GM-CSF promoter [PDF]

open access: yes, 2015
Granulocyte macrophage-colony stimulating factor (GM-CSF) is produced by T cells, but not B cells, in response to immune signals. GM-CSF gene activation in response to T-cell stimulation requires remodelling of chromatin associated with the gene ...

Spermatid-specific linker histone HILS1 is a poor condenser of DNA and chromatin and preferentially associates with LINE-1 elements

open access: yesEpigenetics & Chromatin, 2018
Background Linker histones establish and maintain higher-order chromatin structure. Eleven linker histone subtypes have been reported in mammals. HILS1 is a spermatid-specific linker histone, and its expression overlaps with the histone–protamine ...

Defining the chromatin signature of inducible genes in T cells [PDF]

open access: yes, 2016
BACKGROUND Specific chromatin characteristics, especially the modification status of the core histone proteins, are associated with active and inactive genes. There is growing evidence that genes that respond to environmental or developmental signals may

Influence of M-phase chromatin on the anisotropy of microtubule asters [PDF]

open access: yes, 1996
In many eukaryotic cells going through M-phase, a bipolar spindle is formed by microtubules nucleated from centrosomes. These microtubules, in addition to being "captured" by kinetochores, may be stabilized by chromatin in two different ways: short-range

Transposable Element Dynamics and Regulation during Zygotic Genome Activation in Mammalian Embryos and Embryonic Stem Cell Model Systems

open access: yesStem Cells International, 2021
Transposable elements (TEs) are mobile genetic sequences capable of duplicating and reintegrating at new regions within the genome. A growing body of evidence has demonstrated that these elements play important roles in host genome evolution, despite ...

Investigation of the acetic acid stress response in Saccharomyces cerevisiae with mutated H3 residues

open access: yesMicrobial Cell, 2023
Enhanced levels of acetic acid reduce the activity of yeast strains employed for industrial fermentation-based applications. Therefore, unraveling the genetic factors underlying the regulation of the tolerance and sensitivity of yeast towards acetic acid

Cytoplasmic chromatin triggers inflammation in senescence and cancer [PDF]

open access: yes, 2017
Chromatin is traditionally viewed as a nuclear entity that regulates gene expression and silencing. However, we recently discovered the presence of cytoplasmic chromatin fragments that pinch off from intact nuclei of primary cells during senescence, a ...

Quantifying nuclear wide chromatin compaction by phasor analysis of histone Förster resonance energy transfer (FRET) in frequency domain fluorescence lifetime imaging microscopy (FLIM) data. [PDF]

open access: yes, 2020
The nanometer spacing between nucleosomes throughout global chromatin organisation modulates local DNA template access, and through continuous dynamic rearrangements, regulates genome function [1].
