Determinants and dynamics of genome accessibility

O Bell, VK Tiwari, NH Thomä, D Schübeler - Nature Reviews Genetics, 2011 - nature.com
In eukaryotes, all DNA-templated reactions occur in the context of chromatin. Nucleosome
packaging inherently restricts DNA accessibility for regulatory proteins but also provides an …

[HTML][HTML] Dynamics and memory of heterochromatin in living cells

NA Hathaway, O Bell, C Hodges, EL Miller, DS Neel… - Cell, 2012 - cell.com
Posttranslational histone modifications are important for gene regulation, yet the mode of
propagation and the contribution to heritable gene expression states remains controversial. To …

The histone chaperone CAF-1 safeguards somatic cell identity

…, M Fellner, D Wenzel, M Zinner, SE Vidal, O Bell… - Nature, 2015 - nature.com
Cellular differentiation involves profound remodelling of chromatic landscapes, yet the
mechanisms by which somatic cell identity is subsequently maintained remain incompletely …

Altered body iron distribution and microcytosis in mice deficient in iron regulatory protein 2 (IRP2)

B Galy, D Ferring, B Minana, O Bell, HG Janser… - Blood, 2005 - ashpublications.org
Iron regulatory protein 2 (IRP2)-deficient mice have been reported to suffer from late-onset
neurodegeneration by an unknown mechanism. We report that young adult Irp2 -/- mice …

Variant histone H3. 3 is deposited at sites of nucleosomal displacement throughout transcribed genes while active histone modifications show a promoter-proximal …

C Wirbelauer, O Bell, D Schübeler - Genes & development, 2005 - genesdev.cshlp.org
Deposition of variant histones provides a mechanism to reset and to potentially specify
chromatin states. We determined the distribution of H3 and its variant H3.3 relative to chromatin …

Localized H3K36 methylation states define histone H4K16 acetylation during transcriptional elongation in Drosophila

O Bell, C Wirbelauer, M Hild, AND Scharf… - The EMBO …, 2007 - embopress.org
Post‐translational modifications of histones are involved in transcript initiation and elongation.
Methylation of lysine 36 of histone H3 (H3K36me) resides promoter distal at transcribed …

Chromatin state marks cell-type-and gender-specific replication of the Drosophila genome

M Schwaiger, MB Stadler, O Bell, H Kohler… - Genes & …, 2009 - genesdev.cshlp.org
Duplication of eukaryotic genomes during S phase is coordinated in space and time. In
order to identify zones of initiation and cell-type- as well as gender-specific plasticity of DNA …

The effects of beetroot juice supplementation on indices of muscle damage following eccentric exercise

T Clifford, O Bell, DJ West, G Howatson… - European journal of …, 2016 - Springer
Purpose Foods rich in antioxidant and anti-inflammatory phytochemicals might attenuate
skeletal muscle damage; thus, the present study investigated whether consuming an …

Heterochromatin definition and function

O Bell, A Burton, C Dean, SM Gasser… - … Reviews Molecular Cell …, 2023 - nature.com
Heterochromatin is a key characteristic of eukaryotic genomes. Since its cytological description
nearly 100 years ago, our understanding of heterochromatin features and functions, …

Accessibility of the Drosophila genome discriminates PcG repression, H4K16 acetylation and replication timing

O Bell, M Schwaiger, EJ Oakeley, F Lienert… - Nature structural & …, 2010 - nature.com
Histone modifications are thought to regulate gene expression in part by modulating DNA
accessibility. Here, we measured genome-wide DNA accessibility in Drosophila melanogaster …
