Characterization of Two Satellite DNA Families in the Genome of the Oomycete Plant Pathogen Phytophthora parasitica

open access: yesFrontiers in Genetics, 2020
Satellite DNA is a class of repetitive sequences that are organized in long arrays of tandemly repeated units in most eukaryotes. Long considered as selfish DNA, satellite sequences are now proposed to contribute to genome integrity.

DNA Methylation Patterns of a Satellite Non-coding Sequence – FA-SAT in Cancer Cells: Its Expression Cannot Be Explained Solely by DNA Methylation

open access: yesFrontiers in Genetics, 2019
Satellite ncRNAs are emerging as key players in cell and cancer pathways. Cancer-linked satellite DNA hypomethylation seems to be responsible for the overexpression of satellite non-coding DNAs in several tumors.

Satellite DNA libraries and centromere evolution [PDF]

open access: yes, 2008
Related species share a pool of satellite DNA sequences known as a satellite DNA library. Such sequences may persist in the genome for long evolutionary time at latent locations and can be amplified in any species.

Conformations of satellite DNAs

open access: yesNucleic Acids Research, 1976
X-ray fiber diffraction studies of satellite DNAs from Gecarcinus lateralis, Drosophila virilis and Mus musculus, all of which have highly repetitious base sequences but with different degrees of sequence complexity, reveal only classical polynucleotide duplex structures in contrast to some highly repetitious synthetic DNAs.

Assessing the Epigenetic Status of Human Telomeres [PDF]

open access: yes, 2019
The epigenetic modifications of human telomeres play a relevant role in telomere functions and cell proliferation. Therefore, their study is becoming an issue of major interest.

RNA from a simple-tandem repeat is required for sperm maturation and male fertility in Drosophila melanogaster. [PDF]

open access: yes, 2019
Tandemly-repeated DNAs, or satellites, are enriched in heterochromatic regions of eukaryotic genomes and contribute to nuclear structure and function. Some satellites are transcribed, but we lack direct evidence that specific satellite RNAs are required ...

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 ...

Repeats as global DNA methylation marker in bovine preimplantation embryos [PDF]

open access: yes, 2017
DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive
