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.

Low diversity, activity, and density of transposable elements in five avian genomes

TL;DR: It is suggested that the current and recent activity of TEs in avian genomes is very limited, which may be one of the reasons of small genome sizes in birds.

Mechanism by which a LINE protein recognizes its 3′ tail RNA

TL;DR: It is demonstrated that the region between the endonuclease and reverse transcriptase domains in ORF2 is the site at which the proteins bind the stem-loop structure of the 3′ tail RNA, showing that the strict recognition of the stem -loop structure by the cognate OrF2 protein is an important step in retrotransposition.

Transition of LINE-1 DNA methylation status and altered expression in first and third trimester placentas.

TL;DR: Evidence is provided for a dynamic temporal regulation of LINE-1 methylation and activation during placental development and laid a foundation for future investigation on the function of Line-1 expression in human placenta under different patho-physiological conditions.

L1 retrotransposon-mediated stable gene silencing

TL;DR: A simple L1 retrotransposon-based system for the delivery of small interfering RNA (siRNA) and stable silencing in human cells and demonstrated long-term siRNA expression and significant reduction in both exogenous and endogenous gene expression by up to 90%.

Codon usage biases of transposable elements and host nuclear genes in Arabidopsis thaliana and Oryza sativa.

TL;DR: A remarkable positive correlation between highly expressed nuclear genes and C/G-ending codons were detected in O. sativa and A. thaliana, indicating a close association between the GC content and gene expression level in monocot species.

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.
