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 ...

Regenerative capacity of old muscle stem cells declines without significant accumulation of DNA damage.

open access: yesPLoS ONE, 2013
The performance of adult stem cells is crucial for tissue homeostasis but their regenerative capacity declines with age, leading to failure of multiple organs.

Evolutionary Dynamics of Satellite DNA Repeats across the Tettigoniidae Family: Insights from Genomic Analysis

open access: yesBiomolecules
Satellite DNA repeats are repetitive DNA sequences found in eukaryotic genomes, typically consisting of short DNA motifs repeated in tandem arrays. Despite the vast body of literature on satellite DNA repeats in other taxa, investigations specifically ...

Comparative repeatome analysis on Triatoma infestans Andean and Non-Andean lineages, main vector of Chagas disease.

open access: yesPLoS ONE, 2017
Triatoma infestans is the most important Chagas disease vector in South America. Two main evolutionary lineages, named Andean and non-Andean, have been recognized by geographical distribution, phenetic and genetic characteristics.

Histone modifications within the human X centromere region. [PDF]

open access: yesPLoS ONE, 2009
Human centromeres are multi-megabase regions of highly ordered arrays of alpha satellite DNA that are separated from chromosome arms by unordered alpha satellite monomers and other repetitive elements.

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.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

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 ...

DNA Environment of Centromeres and Non-Homologous Chromosomes Interactions in Mouse

open access: yesCells, 2021
Although the pericentromeric regions of chromosomes that are enriched in tandemly repeated satellite DNA represent a significant part of eukaryotic genomes, they remain understudied, which is mainly due to interdisciplinary knowledge gaps. Recent studies
