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.

Extensive mitochondrial DNA transfer in a rapidly evolving rodent has been mediated by independent insertion events and by duplications.

TL;DR: The data suggest that numt translocation in MicroTus is more extensive than in either Mus or in Rattus, consistent with the elevated rate of speciation, karyotypic rearrangement, and mitochondrial DNA evolution in Microtus.

Evolution and expression of chimeric POTE–actin genes in the human genome

TL;DR: The detection of the 120-kDa POTE–actin fusion protein in breast cancer cell lines known to express the fusion transcript indicates that new functional human genes can evolve by insertion of retroposons.

Regulatory non-coding transcripts in spermatogenesis: shedding light on 'dark matter'.

TL;DR: Recent progress in understanding about the involvement of ncRNAs including microRNAs, PIWI‐interacting RNAs, endogenous small‐interfering RNAs and long non‐coding RNAs as controller of gene expression at transcriptional as well as post‐transcriptional level in different biological context and disease processes is discussed.

Handling multi-mapped reads in RNA-seq

TL;DR: The mechanisms leading to sequence duplication, the biotypes affected, the computational strategies employed to deal with multi-mapped reads and the challenges that still remain to be overcome are discussed.

Increased expression and copy number amplification of LINE-1 and SINE B1 retrotransposable elements in murine mammary carcinoma progression

TL;DR: It is reported that both LINE-1 and SINE B1 retrotransposons are up-regulated at a very early stage of tumorigenesis, indicating that RT activity is distinctive of breast cancer cells and that, furthermore, LINE- 1 and Sine B1 undergo copy number amplification during cancer progression.

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.
