TranscriptomicsProbing the initiation and effector phases of the somatic piRNA pathway in Drosophila
Combining RNAi in cultured cells and analysis of mutant animals, we probed roles of known piRNA pathway components in the initiation and effector phases of transposon silencing. total RNA and RNA associated with Piwi was isolated and size-fractionated by PAGE into 19-29nt. These were processed and s...

TranscriptomicsHierarchical rules for Argonaute loading in Drosophila
Drosophila Argonaute-1 and Argonaute-2 differ in function and small RNA content. AGO2 binds to siRNAs, whereas AGO1 is almost exclusively occupied by microRNAs. microRNA duplexes are intrinsically asymmetric, with one strand, the miR strand, preferentially entering AGO1 to recognize and regulate the...

TranscriptomicsThe let-7-Imp axis regulates aging of the Drosophila testis stem cell niche.
Adult stem cells support tissue homeostasis and repair throughout the life of an individual. However, numerous intrinsic and extrinsic changes occur with age that result in altered stem cell behavior and reduced tissue maintenance and regeneration. In the Drosophila testis, stem cells surround and c...

TranscriptomicsAscaris suum Small RNA-Seq data
Eukaryotic cells express several classes of small RNAs that regulate gene expression and ensure genome maintenance. Endogenous siRNAs (endo-siRNAs) and Piwi-interacting RNAs (piRNAs) mainly control gene and transposon expression in the germline, while microRNAs (miRNAs) generally function in post-tr...

TranscriptomicsProcessing of Drosophila endo-siRNAs depends on a specific Loquacious isoform
Drosophila melanogaster expresses three classes of small RNAs, which are classified according to their mechanisms of biogenesis. MicroRNAs are ~22-23-nt, ubiquitously expressed small RNAs that are sequentially processed from hairpin-like precursors by Drosha/Pasha and Dcr-1/Loquacious complexes. Mic...

TranscriptomicsProduction of artificial piRNAs in flies and mice
In animals, a discrete class of small RNAs, the piwi-interacting RNAs (piRNAs), guard germ cell genomes against the activity of mobile genetic elements. piRNAs are generated, via an unknown mechanism, from apparently single-stranded precursors that arise from discrete genomic loci, termed piRNA clus...

TranscriptomicsA genome-scale shRNA resource for transgenic RNAi in Drosophila
Existing transgenic RNAi resources in Drosophila utilize the expression of long double stranded hairpin RNAs and are powerful tools for the identification and characterization of genes involved in various processes. However, they are ineffective to knockdown genes during oogenesis, an important mode...
