Fission yeast condensin contributes to interphase chromatin organization and prevents transcription-coupled DNA damage

Genome Biology, 2020
Background Structural maintenance of chromosomes (SMC) complexes are central organizers of chromatin architecture throughout the cell cycle. The SMC family member condensin is best known for establishing long-range chromatin interactions in mitosis ...

MECP2, a multi-talented modulator of chromatin architecture [PDF]

Briefings in Functional Genomics, 2016
It has been a long trip from 1992, the year of the discovery of MECP2, to the present day. What is surprising is that some of the pivotal roles of MeCP2 were already postulated at that time, such as repression of inappropriate expression from repetitive elements and the regulation of pericentric heterochromatin condensation.

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Initial Genomics of the Human Nucleolus [PDF]

, 2010
We report for the first time the genomics of a nuclear compartment of the eukaryotic cell. 454 sequencing and microarray analysis revealed the pattern of nucleolus-associated chromatin domains (NADs) in the linear human genome and identified different ...

NoRC, a novel chromatin remodeling complex involved in ribosomal RNA gene silencing [PDF]

, 2004
Regulation of gene expression takes place in the nucleus in a highly structured and condensed nucleoprotein environment, called chromatin (Felsenfeld and Groudine, 2003; Khorasanizadeh, 2004; Vaquero et al., 2003).

Decoding the role of chromatin architecture in development: coming closer to the end of the tunnel.

Frontiers in Plant Science, 2014
Form and function in biology are intimately related aspects that are often difficult to untangle. While the structural aspects of chromatin organization were apparent from early cytological observations long before the molecular details of chromatin ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

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

, 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.

The insulator EACBE regulates V(D)J recombination of Tcrd gene by modulating chromatin organization

Frontiers in Immunology
T cell receptor (TCR) diversity, essential for the recognition of a wide array of antigens, is generated through V(D)J recombination. The Tcra and Tcrd genes reside within a shared genomic locus, with Tcrd rearrangement occurring first in the double ...

Pioneer factors outline chromatin architecture

Current Opinion in Cell Biology
Pioneer factors are transcription factors capable of binding to nucleosomal DNA, initiating chromatin opening, and facilitating gene expression. By overcoming nucleosomes, pioneer factors enable cellular reprogramming, tissue-specific gene expression, and genome response to external stimuli.
