Condition optimization for electroporation transfection in horse skeletal muscle satellite cells

Animal Biotechnology
Satellite cells are an important cellular model for studying muscle growth and development and mammalian locomotion-related molecular mechanisms. In this study, we investigated the effects of voltage, pulse duration, and DNA dosage on horse skeletal ...

Begomovirus-Associated Satellite DNA Diversity Captured Through Vector-Enabled Metagenomic (VEM) Surveys Using Whiteflies (Aleyrodidae)

Viruses, 2016
Monopartite begomoviruses (Geminiviridae), which are whitefly-transmitted single-stranded DNA viruses known for causing devastating crop diseases, are often associated with satellite DNAs.

Bundling up DNA

eLife, 2018
Structures known as chromocenters, comprising satellite DNA and proteins such as D1 or HMGA1, help to contain DNA inside the nucleus between cell divisions.

Linajes de Trypanosoma cruzi en pacientes con enfermedad de Chagas y coinfección por VIH [PDF]

, 2009
Introducción. Las poblaciones naturales de T. cruzi han sido clasificadas en seis linajes filogenéticos o unidades de tipificación discreta: T. cruzi I, IIa, IIb, IIc, IId y IIe, que pueden jugar un rol en el tropismo tisular y patogénesis de la ...

Comparative Analysis of Satellite DNA in the Drosophila melanogaster Species Complex

G3: Genes, Genomes, Genetics, 2017
Satellite DNAs are highly repetitive sequences that account for the majority of constitutive heterochromatin in many eukaryotic genomes. It is widely recognized that sequences and locations of satellite DNAs are highly divergent even in closely related ...

Genomic characterization of repetitive DNA and transposable elements in Dyckia (Pitcairnioideae) species

BMC Research Notes
Objective Repetitive DNA comprises the majority of nuclear genomes in eukaryotes and is critical for genome stability, gene regulation and evolutionary innovation. Yet, most genomic surveys focus on lowcopy regions, leaving repeats underexplored.

Topoisomerase I is an evolutionarily conserved key regulator for satellite DNA transcription

Nature Communications
RNA Polymerase (RNAP) II transcription on non-coding repetitive satellite DNAs plays an important role in chromosome segregation, but a little is known about the regulation of satellite transcription.

DNA demethylation and heterochromatin remodelling upon heat stress [PDF]

, 2012
Conversion of environmental signals into epigenetic information is thought to occur widely but has been poorly studied as yet. It is proposed that changes in the expression of molecules involved in chromatin remodelling or their modification might play a
