Transposable elements in mosquitoes

Cytogenetic and Genome Research, 2005
We describe the current state of knowledge about transposable elements (TEs) in different mosquito species. DNA-based elements (class II elements), non-LTR retrotransposons (class I elements), and MITEs (Miniature Inverted Repeat Transposable Elements) are found in the three genera, <i>Anopheles, Aedes</i> and <i>Culex</i> ...

Transposable Elements and Cancer

1986
Tumor progression is accompanied by many chromosomal aberrations and DNA rearrangements which contribute to the aggressiveness of the tumor. It is possible that active transposition of DNA elements play a role in these events. Approximately one third of the mammalian genome is composed of repetitive sequences (103 — 105 copies).

Evolution of transposable elements

Journal of Antimicrobial Chemotherapy, 1986
Transposable elements are at an advantage compared with other DNA sequences. This has led to the generation of transposable systems from a variety of different sources. Once fabricated, these elements can very simply acquire accessory genes, such as those that encode resistance to antibiotics.

Transposable elements in cancer

Nature Reviews Cancer, 2017
Transposable elements give rise to interspersed repeats, sequences that comprise most of our genomes. These mobile DNAs have been historically underappreciated - both because they have been presumed to be unimportant, and because their high copy number and variability pose unique technical challenges. Neither impediment now seems steadfast. Interest in

Transposable Elements in Yeast

1983
Publisher Summary Transposable elements are the DNA sequences that move to new genomic locations at a much higher rate than that of the bulk of the cellular DNA. The ability to cause deletions or chromosomal rearrangements is characteristic of these elements, and many have been shown to affect the expression of chromosomal genes by inserting adjacent

Transposable Elements in Nematodes

1994
Transposable elements are present in the genomes of most, if not all, organisms. Because of their ability to insert into and excise from the chromosomes of their hosts transposons are a significant source of spontaneous mutations in organisms. Therefore they can be used as a tool for cloning genes that have been identified by mutations and for which no

Transposable Elements in Eukaryotes

1985
Publisher Summary This chapter classifies transposable elements according to their structure. It reviews some of the information available concerning transposable elements of each type. It also discusses some questions raised by transposable elements in general, particularly with regard to their biological significance and their possible use as ...
