Project description:Small RNAs are now known to be major regulatory factors of gene expression. Emerging methods based on deep-sequencing have enabled the analysis of small RNA expression in a high-throughput manner, leading to the identification of large numbers of small RNAs in various species. Moreover, profiling small RNA data together with transcriptome data enables transcriptional and post-transcriptional regulation mediated by small RNAs to be hypothesized. Here, we isolated PIWIL1 (MIWI)-associated small RNAs from mouse testes, and performed small RNA-seq analysis. In addition, directional RNA-seq was performed using Piwil1 mutant mouse testes. Using these data, we describe protocols for analyzing small RNA-seq reads to obtain profiles of small RNAs associated with PIWI proteins. We also present bioinformatic protocols for analyzing RNA-seq reads that aim to annotate expression of piRNA clusters and identify genes regulated by piRNAs.

Project description:Small RNAs mediate gene silencing by binding Argonaute/Piwi proteins to regulate target RNAs. Here we describe small RNA profiling of the adult testes of Callithrix jacchus, the common marmoset. The most abundant class of small RNAs in the adult testis was piRNAs, while 353 novel miRNAs but few endo-siRNAs were also identified. MARWI, a marmoset homolog of mouse MIWI and a very abundant PIWI in adult testes, associates with piRNAs that show characteristics of mouse pachytene piRNAs. As in other mammals, most marmoset piRNAs are derived from conserved clustered regions in the genome, which are annotated as intergenic regions. However, some of these piRNA cluster regions contain antisense-orientated pseudogenes, suggesting regulation of parental functional protein-coding genes. More piRNAs map to transposable element (TE) subfamilies when they have copies in piRNA clusters. In addition, the strand-bias observed for piRNAs mapped to each TE subfamily correlates with the polarity of copies inserted in clusters. These findings suggest that pachytene piRNA clusters determine the abundance and strand-bias of TE-derived piRNAs, and also regulate protein-coding genes via pseudogene-derived piRNAs. small RNA levels in the adult marmoset testis, and MARWI-IP small RNA levels and RNA levels from the adult marmoset testis with two replicates.
