GenomicsSynMyco transposon: engineering transposon vectors for efficient transformation of minimal genomes
This sample was prepared with a modified version of the Tn4001 transposon commonly used in Mycoplasmas. This transposon is described to work more efficiently in Mycoplasma agalactiae and, by extension, in other Mycoplasma species. This sample was prepared transforming this bacteria with a newly desi...

TranscriptomicsMIWI catalysis is required for piRNA amplification-independent LINE1 transposon silencing
This SuperSeries is composed of the following subset Series: GSE32180: MIWI catalysis is required for piRNA amplification-independent LINE1 transposon silencing [microarray] GSE32184: MIWI catalysis is required for piRNA amplification-independent LINE1 transposon silencing [deep sequencing] Refer to...

TranscriptomicsMIWI catalysis is required for piRNA amplification-independent LINE1 transposon silencing [microarray]
Here we show that MIWI is a small RNA-guided ribonuclease (Slicer) that requires extensive complementarity for target cleavage in vitro. Disruption of its catalytic activity in mice by a single point mutation results in male infertility and displays increased accumulation of LINE1 transposon transcr...

TranscriptomicsAn epigenetic role for maternally inherited piRNAs in transposon silencing
In plants and mammals, small RNAs indirectly mediate epigenetic inheritance by specifying cytosine methylation. Here, we find that small RNAs themselves serve as vectors for epigenetic information. Crosses between Drosophila strains that differ in the presence of a particular transposon can pr...

GenomicsClonal expansion analysis of transposon insertions by high-throughput sequencing identifies candidate cancer genes in a PiggyBac mutagenesis screen
Somatic transposon mutagenesis in mice is an efficient strategy to investigate the genetic mechanisms of tumorigenesis. The identification of tumor driving transposon insertions traditionally requires the generation of large tumor cohorts to obtain information about common insertion sites. Tumor dri...

TranscriptomicsDe novo piRNA cluster formation in the Drosophila germline triggered by transgenes containing a transcribed transposon fragment
PIWI interacting RNAs (piRNAs) provide defense against transposable element (TE) expansion in the germline of metazoans. piRNAs are processed from the transcripts encoded by specialized heterochromatic clusters enriched in damaged copies of transposons. How these regions are recognized as a source o...

TranscriptomicsRNA clamping by Vasa assembles a piRNA Amplifier complex on transposon transcripts
Germline-specific Piwi-interacting RNAs (piRNAs) protect the genome against selfish genetic elements and are essential for fertility in animals. piRNAs targeting active transposons are amplified by a feed-forward loop known as the Ping-pong cycle, which links endonucleolytic slicing of target RNA...

TranscriptomicsUAP56 couples piRNA clusters to the perinuclear transposon silencing machinery [tiling array]
The transposon silencing piRNAs are produced from precursors that are encoded by heterochromatic clusters and processed in the perinuclear nuage. We show that the Drosophila nuclear DEAD box protein UAP56, previously implicated in mRNA splicing and nuclear export, co-localizes with the cluster-assoc...

TranscriptomicsTransposon-based construction of strand-specific RNA-seq libraries
We have developed two methods for efficiently consructing RNA-seq libraries using transposition. Each method constructs high quality RNA-seq libraries when compared to standard approaches. One of the methods (Directional Tn-RNA-seq) maintains strand-of-origin information and exhibits strand specifi...
