Mobile elements within genomes have driven genome evolution in diverse ways and are becoming useful tools for learning more about genome evolution and gene function.
Abstract
Mobile elements within genomes have driven genome evolution in diverse ways. Particularly in plants and mammals, retrotransposons have accumulated to constitute a large fraction of the genome and have shaped both genes and the entire genome. Although the host can often control their numbers, massive expansions of retrotransposons have been tolerated during evolution. Now mobile elements are becoming useful tools for learning more about genome evolution and gene function.

Myriad Triple-Helix-Forming Structures in the Transposable Element RNAs of Plants and Fungi

TL;DR: Their presence in intronless, but not intron-containing, hAT transposase genes supports the idea that TEs acquired ENEs to counteract the RNA-destabilizing effects of intron loss, a potential evolutionary consequence of TE horizontal transfer in organisms that couple RNA silencing to splicing deficits.

Genome-wide analysis of mobile genetic element insertion sites

TL;DR: The genomes of Homo sapiens, Mus musculus, Drosophila melanogaster and Entamoeba histolytica are studied via a protocol whereby DNASCANNER is used to identify a common set of statistically important signals flanking the insertion sites in the various genomes, suggesting a common insertion mechanism that operates in a variety of eukaryotes.

PIWI-interacting RNAs (piRNAs) - a mouse testis perspective.

TL;DR: This review will focus on the genomic origins, biogenesis, and function of piRNAs in the mouse testis — an exceptionally robust experimental system amenable to genetic, cell-biological, molecular, and biochemical studies.
Journal ArticleDOI

Perspective on mutagenesis and repair: the standard model and alternate modes of mutagenesis.

TL;DR: An emerging paradigm is defined that describes how mechanisms exist that can direct point mutations to specific designated genes or regions of genes, and how high mutability is programmed into the sequence of certain genes to help generate diversity.
Journal ArticleDOI

Fishing for answers with transposons

TL;DR: Results of these studies show that SB-mediated trans genesis is more efficient than that by injection of simple plasmids and that expression of transgenesis is stable and reliable following passage through the germline.

hEST2, the Putative Human Telomerase Catalytic Subunit Gene, Is Up-Regulated in Tumor Cells and during Immortalization

TL;DR: The cloning of a human gene, hEST2, that shares significant sequence similarity with the telomerase catalytic subunit genes of lower eukaryotes is reported, suggesting that the induction of hEST 2 mRNA expression is required for the telomersase activation that occurs during cellular immortalization and tumor progression.

HIV-1 Integration in the Human Genome Favors Active Genes and Local Hotspots

TL;DR: Global analysis of cellular transcription indicated that active genes were preferential integration targets, particularly genes that were activated in cells after infection by HIV-1, and this data suggests how selective targeting promotes aggressive HIV replication.
