(Submitter supplied) We report the transcriptional profiles obtained by next-generation sequencing (NGS) of FACS-purified somatic cyst stem cells (CySCs) from adult testes of Drosophila melanogaster. The goals of this study are to compare NGS-derived transcriptome profiling (RNA-seq) of wild type CySCs to those that have decreased Chinmo, increased Chinmo, elevated JAK/STAT signaling or elevated Hh signaling.

(Submitter supplied) Here we used laser cutting microdissection and RNA amplification to profile the gene expression in wildtype female germaria and male apex of the testes. These tissue contain germline stem cells and early dividing germ cells. Our goal was to identify genes expressed in these cell types.

(Submitter supplied) Both transcription and post-transcriptional processes, such as alternative splicing, play crucial roles in controlling developmental programs in metazoans. Recently emerged RNA-seq method has brought our understanding of eukaryotic transcriptomes to a new level, because it can resolve both gene expression level and alternative splicing events simultaneously. To gain a better understanding of cellular differentiation in gonads, we analyzed mRNA profiles from Drosophila testes and ovaries using RNA-seq. more...

(Submitter supplied) Here we employed a FACS-based approach for isolation of early and mature somatic cyst cells from whole testes of adult Drosophila males. We prepared and analyzed RNA-seq libraries to reveal differences in transcriptional patterns of these cells and to uncover protein complexes functioning in cyst cells at different stages of spermatogenesis.

(Submitter supplied) Whereas in ovo exposure of genetically male (ZZ) chicken embryos to exogenous estrogens temporarily feminizes gonads at the time of hatching, the morphologically ovarian ZZ-gonads (FemZZs for feminized ZZ gonads) are masculinized back to testes within one year. To identify the feminization-resistant “memory” of genetic male sex, FemZZs showing varying degrees of feminization were subjected to transcriptomic, DNA methylome, and immunofluorescence analyses. more...

(Submitter supplied) The Piwi-piRNA pathway is well known for its germline function, yet its somatic role remains elusive. We show here that Piwi is required autonomously not only for germline stem cell (GSC) but also for somatic cyst stem cell (CySC) maintenance in the Drosophila testis. Reducing Piwi activity in the testis caused defects in CySC differentiation. Accompanying this, GSC daughters expanded beyond the vicinity of the hub but failed to differentiate further. more...

(Submitter supplied) piRNAs function in silencing retrotransposons by associating with the PIWI proteins, AGO3, Aub, and Piwi, in Drosophila germlines. Bioinformatics analyses of piRNAs in Drosophila ovaries suggested that piRNAs are produced by two systems, the primary processing pathway and the amplification loop, from repetitive genes and piRNA clusters in the genome. The amplification loop occurs in a Dicer-independent, PIWI-Slicer-dependent manner. more...

(Submitter supplied) Fetal life is a crucial period for sexual reproduction when bipotential gonads differentiate into either a testis or an ovary. Gaining insights into the complex molecular events underlying this process is central to a better understanding of disorders of sexual development. The present work therefore intends to improve the knowledge on molecular pathways at play during gonad development in humans using RNA-Sequencing.

(Submitter supplied) In Drosophila, Piwi proteins associate with Piwi-interacting RNAs (piRNAs) and protect the germline genome by silencing mobile genetic elements. This defense system acts in germline and gonadal somatic tissue to preserve germline development. Genetic control for these silencing pathways varies greatly between tissues of the gonad. Here, we identified Vreteno (Vret), a novel gonad-specific protein essential for germline development. more...

(Submitter supplied) Here, we analyzed small RNA libraries derived from ovarian tissues heterozygous or mutant for the Tudor gene, Vreteno. In the absence of vret, Piwi-bound piRNAs are lost without changes in piRNA precursor transcript production, supporting a role for Vret in primary piRNA biogenesis. In the germline, piRNAs can engage in an Aub/Argonaute 3 (AGO3)-dependent amplification in the absence of Vret, suggesting that Vret function can distinguish between primary piRNAs loaded into Piwi/Aub complexes and piRNAs engaged in the amplification cycle. more...

(Submitter supplied) The Drosophila sex determination hierarchy consists of a splicing cascade with sex-specific transcription directing somatic sexual dimorphism. Our understanding of this pathway, and many others, is incomplete. Here we pioneer an approach to expand our knowledge of gene regulatory networks (GRNs) by leveraging natural genetic variation. This approach is generalizable to any natural population, including humans. more...

(Submitter supplied) Drosophila melanogaster adult males perform an elaborate courtship ritual to entice females to mate. fruitless (fru), a gene that is one of the key regulators of male courtship behavior, encodes multiple male-specific isoforms (FruM). These isoforms vary in their carboxy-terminal zinc finger domains, which are predicted to facilitate DNA binding. By over-expressing individual FruM isoforms in fru-expressing neurons in either males or females and assaying the global transcriptional response by RNA-sequencing, we show that three FruM isoforms have different regulatory activities that depend on the sex of the fly. more...

(Submitter supplied) The piRNA pathway is an adaptive mechanism for maintaining the stability of the genome by repression selfish genomic elements such as transposons. As a host defense mechanism the piRNA pathway is rapidly evolving with different sets of piRNA silencing different targets in closely-related species. In male germline of D.melanogaster, repression of Stellate genes by piRNA generated from Supressor of Stellate, Su(Ste), locus is required for male fertility, but both Su(Ste) piRNA and their targets are absent in other Drosophila species. more...
