Repetitive elements in genomes of parasitic protozoa.
Repetitive DNA elements have been a part of the genomic fauna of eukaryotes perhaps since their very beginnings. Millions of years of coevolution have given repeats central roles in chromosome maintenance and genetic modulation. Here we review the genomes of parasitic protozoa in the context of the current understanding of repetitive elements. Particular reference is made to repeats in five med...
متن کاملRepetitive Elements in Mycoplasma hyopneumoniae Transcriptional Regulation
Transcriptional regulation, a multiple-step process, is still poorly understood in the important pig pathogen Mycoplasma hyopneumoniae. Basic motifs like promoters and terminators have already been described, but no other cis-regulatory elements have been found. DNA repeat sequences have been shown to be an interesting potential source of cis-regulatory elements. In this work, a genome-wide sea...
متن کاملSequencing homopolymer tracts and repetitive elements.
We investigated the use of Taq dye primer and Taq terminator sequencing chemistry to optimize the quality of sequence data obtained from templates containing homopolymer tracts and repetitive elements. In direct side-by-side comparisons using the Applied Biosystems Model 373A Fluorescent Sequencer, the Taq terminator sequencing chemistry gave much cleaner and more consistent results on long hom...
متن کاملA repetitive elements perspective in Polycomb epigenetics
Repetitive elements comprise over two-thirds of the human genome. For a long time, these elements have received little attention since they were considered non-functional. On the contrary, recent evidence indicates that they play central roles in genome integrity, gene expression, and disease. Indeed, repeats display meiotic instability associated with disease and are located within common frag...
متن کاملLsh, an epigenetic guardian of repetitive elements.
The genome is burdened with repetitive sequences that are generally embedded in silenced chromatin. We have previously demonstrated that Lsh (lymphoid-specific helicase) is crucial for the control of heterochromatin at pericentromeric regions consisting of satellite repeats. In this study, we searched for additional genomic targets of Lsh by examining the effects of Lsh deletion on repeat regio...
