Compositional and structural analysis of selected chromosomal domains from Saccharomyces cerevisiae [PDF]

, 2012
In eukaryotic genomes, chromatin is the template of all nuclear processes including transcription, recombination and replication. Besides the wrapping of DNA in nucleosome core particles, eukaryotic chromatin is associated, interpreted and modified by ...

CHRAC/ACF contribute to the repressive ground state of chromatin

Life Science Alliance, 2018
Chromatin accessibility complex/ATP-utilizing chromatin assembly and remodeling factor help to establish basal transcriptional repression, conceivably through improving the regular spacing of nucleosomes in euchromatin. The chromatin remodeling complexes

Stress-Induced PARP Activation Mediates Recruitment of Drosophila Mi-2 to Promote Heat Shock Gene Expression [PDF]

, 2011
Eukaryotic cells respond to genomic and environmental stresses, such as DNA damage and heat shock (HS), with the synthesis of poly-ADP-ribose] (PAR) at specific chromatin regions, such as DNA breaks or HS genes, by PAR polymerases (PARP). Little is known

The Adenomatous Polyposis Coli protein contributes to normal compaction of mitotic chromatin [PDF]

, 2012
The tumour suppressor <i>Adenomatous Polyposis Coli</i> (APC) is required for proper mitosis; however, the exact role of APC in mitosis is not understood.

Mechanism of chromatin reassembly at the yeast PHO5 promoter upon repression [PDF]

, 2007
The goal of this study has been to elucidate the mechanisms responsible for rebuilding nucleosomes at the PHO5 promoter upon rerepression. In this work, I could unambiguously show that histones are incorporated at the PHO5 promoter upon repression ...

Dynamic remodeling of individual nucleosomes across a eukaryotic genome in response to transcriptional perturbation. [PDF]

PLoS Biology, 2008
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined ...

Mutations to the histone H3 alpha N region selectively alter the outcome of ATP-dependent nucleosome-remodelling reactions [PDF]

, 2009
Mutational analysis of the histone H3 N-terminal region has shown it to play an important role both in chromatin function in vivo and nucleosome dynamics in vitro.

A Double-Edged Role for SIRT7 in Cancer: Can Anti-Cancer Immunity Tip the Balance?

Pharmaceuticals
Background/Objectives: Sirtuin 7 (SIRT7), a nuclear NAD+-dependent deacylase, plays multifaceted and sometimes opposing roles in tumorigenesis. By preserving chromatin architecture and genome integrity, SIRT7 protects against malignant transformation ...

H2A.Z facilitates access of active and repressive complexes to chromatin in embryonic stem cell self-renewal and differentiation. [PDF]

, 2013
SummaryChromatin modifications have been implicated in the self-renewal and differentiation of embryonic stem cells (ESCs). However, the function of histone variant H2A.Z in ESCs remains unclear.
