Influence of DNA methylation on positioning and DNA flexibility of nucleosomes with pericentric satellite DNA [PDF]

open access: yesOpen Biology, 2015
DNA methylation occurs on CpG sites and is important to form pericentric heterochromatin domains. The satellite 2 sequence, containing seven CpG sites, is located in the pericentric region of human chromosome 1 and is highly methylated in normal cells ...

Transcription of Satellite DNAs in Insects

open access: yes, 2010
The very complex life cycle and extreme diversity of insect life forms require a carefully regulated network of biological processes to switch on and off the right genes at the right time. Chromatin condensation is an important regulatory mechanism of gene silencing as well as gene activation for the hundreds of functional protein genes harbored in ...

The structure of alphoid satellite DNA on normal and abnormal human Y chromosomes

open access: yes, 1989
The long-range structure of the Y chromosome alphoid satellite DNA has been determined in the cell lines 3E7 and OXEN. Variation in alphoid DNA block size and restriction enzyme sites were observed.

Repetitive DNA is associated with centromeric domains in Trypanosoma brucei but not Trypanosoma cruzi. [PDF]

open access: yes, 2007
BACKGROUND: Trypanosomes are parasitic protozoa that diverged early from the main eukaryotic lineage. Their genomes display several unusual characteristics and, despite completion of the trypanosome genome projects, the location of centromeric DNA has ...

A recombinant DNA‐satellite associated with Pepper yellow leaf curl Indonesia virus in highland area

open access: yesIndonesian Journal of Biotechnology, 2021
Yellow curl disease caused by begomovirus is a major threat for horticulture in Indonesia. Control mea‐ sures for the disease face several constraints, one of which is the association between begomovirus and DNA satellites which can affect the severity ...

Satellite DNA in insects: a review [PDF]

open access: yesHeredity, 2008
The study of insect satellite DNAs (satDNAs) indicates the evolutionary conservation of certain features despite their sequence heterogeneity. Such features can include total length, monomer length, motifs, particular regions and/or secondary and tertiary structures.

More efficient repair of DNA double-strand breaks in skeletal muscle stem cells compared to their committed progeny

open access: yesStem Cell Research, 2014
The loss of genome integrity in adult stem cells results in accelerated tissue aging and is possibly cancerogenic. Adult stem cells in different tissues appear to react robustly to DNA damage.

Molecular characterization of SSS139, a new satellite DNA family in sibling species of the Drosophila buzzatii cluster

open access: yesGenetics and Molecular Biology, 2008
We characterized sequences of a novel SSS139 RsaI satellite DNA family in Drosophila gouveai and Drosophila seriema, two members of the Drosophila buzzatii cluster (D. repleta group).

Replicating satellite RNA induces sequence-specific DNA methylation and truncated transcripts in plants

open access: yes, 2001
Tobacco plants were transformed with a chimeric transgene comprising sequences encoding β-glucuronidase (GUS) and the satellite RNA (satRNA) of cereal yellow dwarf luteovirus.

DNA topoisomerases participate in fragility of the oncogene RET [PDF]

open access: yes, 2013
Fragile site breakage was previously shown to result in rearrangement of the RET oncogene, resembling the rearrangements found in thyroid cancer. Common fragile sites are specific regions of the genome with a high susceptibility to DNA breakage under ...
