Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia. [PDF]

open access: yes, 2020
BACKGROUND: Tudor domain-containing proteins (TDRDs) play a critical role in piRNA biogenesis and germ cell development. piRNAs, small regulatory RNAs, act by silencing of transposons during germline development and it has recently been shown in animal ...

A Naturally Active Spy Transposon Discovered from the Insect Genome of Colletes gigas as a Promising Novel Gene Transfer Tool

open access: yesAdvanced Science
Novel active DNA transposons, such as Spy transposons from the PHIS superfamily, are identified through bioinformatics in this study. The native transposases cgSpy and cvSpy displayed transposition activities of approximately 85% and 35% compared to the ...

The Integration Preference of Sleeping Beauty at Non-TA Site Is Related to the Transposon End Sequences

open access: yesFrontiers in Genetics, 2021
Recently, we proved that Sleeping Beauty (SB) transposon integrates into non-TA sites at a lower frequency. Here, we performed a further study on the non-TA integration of SB and showed that (1) SB can integrate into non-TA sites in HEK293T cells as well

Human Transposon Tectonics [PDF]

open access: yesCell, 2012
Mobile DNAs have had a central role in shaping our genome. More than half of our DNA is comprised of interspersed repeats resulting from replicative copy and paste events of retrotransposons. Although most are fixed, incapable of templating new copies, there are important exceptions to retrotransposon quiescence.

Higher yields of cyclodepsipetides from Scopulariopsis brevicaulis by random mutagenesis [PDF]

open access: yes, 2013
The ascomycete Scopulariopsis brevicaulis, which was isolated from the marine sponge Tethya aurantium, produces two cyclodepsipeptides, scopularides A and B [1]. Both peptides exhibit activity against several tumor cell lines.

Transposon variants and their effects on gene expression in arabidopsis [PDF]

open access: yes, 2013
Transposable elements (TEs) make up the majority of many plant genomes. Their transcription and transposition is controlled through siRNAs and epigenetic marks including DNA methylation.

Activity of Genes with Functions in Human Williams-Beuren Syndrome Is Impacted by Mobile Element Insertions in the Gray Wolf Genome. [PDF]

open access: yes, 2018
In canines, transposon dynamics have been associated with a hyper-social behavioral syndrome, although the functional mechanism has yet to be described.

Chromosomal DNA deletion confers phage resistance to Pseudomonas aeruginosa. [PDF]

open access: yes, 2014
Bacteria develop a broad range of phage resistance mechanisms, such as prevention of phage adsorption and CRISPR/Cas system, to survive phage predation.

Global Spread of Multiple Aminoglycoside Resistance Genes

open access: yesEmerging Infectious Diseases, 2005
Emergence of the newly identified 16S rRNA methylases RmtA, RmtB, and ArmA in pathogenic gram-negative bacilli has been a growing concern. ArmA, which had been identified exclusively in Europe, was also found in several gram-negative pathogenic bacilli ...
