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 ...

Male Germline Chromatin [PDF]

open access: yes, 2020
Spermatogenesis requires radical restructuring of germline chromatin at multiple stages, involving coordinated waves of DNA methylation/demethylation, histone modification, and the replacement and removal that occurs before, during, and after meiosis ...

Quantitative analysis of chromatin compaction in living cells using FLIM-FRET [PDF]

open access: yes, 2009
We present a quantitative Forster resonance energy transfer (FRET)-based assay using multiphoton fluorescence lifetime imaging microscopy (FLIM) to measure chromatin compaction at the scale of nucleosomal arrays in live cells. The assay uses a human cell

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 ...

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

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

Repressive and non-repressive chromatin at native telomeres in Saccharomyces cerevisiae [PDF]

open access: yes, 2009
Background In Saccharomyces cerevisiae genes that are located close to a telomere can become transcriptionally repressed by an epigenetic process known as telomere position effect.

Identification and validation of transcription factors that regulate chromatin dynamics [PDF]

open access: yes, 2012
Gene expression has to be tightly regulated during all cellular processes. During embryonic development differentiating cells loose their developmental potential and acquire specific functions by activating lineage-specific genes.

Distinct roles of haspin in stem cell division and male gametogenesis

open access: yesScientific Reports, 2021
The kinase haspin phosphorylates histone H3 at threonine-3 (H3T3ph) during mitosis. H3T3ph provides a docking site for the Chromosomal Passenger Complex at the centromere, enabling correction of erratic microtubule-chromosome contacts.
