Using genomic annotations increases statistical power to detect eGenes. [PDF]

open access: yes, 2016
MotivationExpression quantitative trait loci (eQTLs) are genetic variants that affect gene expression. In eQTL studies, one important task is to find eGenes or genes whose expressions are associated with at least one eQTL. The standard statistical method

Histone variants: deviants? [PDF]

open access: yesGenes & Development, 2005
Histones are a major component of chromatin, the protein-DNA complex fundamental to genome packaging, function, and regulation. A fraction of histones are nonallelic variants that have specific expression, localization, and species-distribution patterns.

Quantitative Kinetic Analyses of Histone Turnover Using Imaging and Flow Cytometry

open access: yesBio-Protocol, 2020
Dynamic histone changes occur as a central part of chromatin regulation. Deposition of histone variants and post-translational modifications of histones are strongly associated with properties of chromatin status.

Chromosome Centromeres: Structural and Analytical Investigations with High Resolution Scanning Electron Microscopy in Combination with Focused Ion Beam Milling [PDF]

open access: yes, 2009
Whole mount mitotic metaphase chromosomes of different plants and animals were investigated with high resolution field emission scanning electron microscopy (FESEM) to study the ultrastructural organization of centromeres, including metacentric ...

A Read/Write Mechanism Connects p300 Bromodomain Function to H2A.Z Acetylation

open access: yesiScience, 2019
Summary: Acetylation of the histone variant H2A.Z (H2A.Zac) occurs at active regulatory regions associated with gene expression. Although the Tip60 complex is proposed to acetylate H2A.Z, functional studies suggest additional enzymes are involved.

Immunoprotective Effects of Two Histone H2A Variants in the Grass Carp Against Flavobacterium columnare Infection

open access: yesFrontiers in Immunology, 2022
In teleost fish, the nucleotide polymorphisms of histone H2A significantly affect the resistance or susceptibility of zebrafish to Edwardsiella piscicida infection.

ATP-dependent chromatosome remodeling [PDF]

open access: yes, 2008
Chromatin serves to package, protect and organize the complex eukaryotic genomes to assure their stable inheritance over many cell generations. At the same time, chromatin must be dynamic to allow continued use of DNA during a cell's lifetime.

Mutations in the PKM2 exon-10 region are associated with reduced allostery and increased nuclear translocation. [PDF]

open access: yes, 2019
PKM2 is a key metabolic enzyme central to glucose metabolism and energy expenditure. Multiple stimuli regulate PKM2's activity through allosteric modulation and post-translational modifications.

Mice without MacroH2A Histone Variants [PDF]

open access: yesMolecular and Cellular Biology, 2014
MacroH2A core histone variants have a unique structure that includes a C-terminal nonhistone domain. They are highly conserved in vertebrates and are thought to regulate gene expression. However, the nature of genes regulated by macroH2As and their biological significance remain unclear.

Reciprocal intronic and exonic histone modification regions in humans. [PDF]

open access: yes, 2010
While much attention has been focused on chromatin at promoters and exons, human genes are mostly composed of intronic sequences. Analyzing published surveys of nucleosomes and 41 chromatin marks in humans, we identified histone modifications ...
