Single-cell RNA-seq of Drosophila melanogaster male late third instar larval gonads

Project description:The male larval gonad is a complex tissue made up of multiple cell types including germ cells and somatic cells. It is also a key developmental stage with the germline undergoing spermatogenesis. The diversity of cell types and transcriptional regulation of the developing gonad has only been broadly described. In order to get single cell resolution, we profiled late third instar larval testes of a reference Drosophila melanogaster genotype, w[1118] using single-cell RNA-Seq (scRNA-Seq). We identified and annotated 9 cell types including 4 stages of the germ cell lineage, and provide transcriptional profiles for each cell type.

Drosophila melanogaster female late third instar larval gonads single-cell RNA-Seq (scRNA-Seq) profiling

Project description:The larval ovary is made up of multiple cell types including germ cells and somatic cells. The diversity of cell types and transcriptional regulation is not fully understood. To get single cell resolution of larval ovary regulation, we generated single-cell RNA expression profiles (scRNA-Seq) from late third instar larval ovaries of a reference Drosophila melanogaster genotype w[1118].

Whole-genome expression analysis in the third instar larval midgut of Drosophila melanogaster.

Project description:Survival of insects on a substrate containing toxic substances such as plant secondary metabolites or insecticides is dependent on the metabolism or excretion of those xenobiotics. The primary sites of xenobiotic metabolism are the midgut, Malpighian tubules, and fat body. In general, gene expression in these organs is reported for the entire tissue by online databases, but several studies have shown that gene expression within the midgut is compartmentalized. Here, RNA sequencing is used to investigate whole-genome expression in subsections of third instar larval midguts of Drosophila melanogaster. The data support functional diversification in subsections of the midgut. Analysis of the expression of gene families that are implicated in the metabolism of xenobiotics suggests that metabolism may not be uniform along the midgut. These data provide a starting point for investigating gene expression and xenobiotic metabolism and other functions of the larval midgut.

Drosophila melanogaster late third instar larval testes and gonadal fatbody RNA-seq profiling

Project description:In order to study the effect of protease treatment on dissected testes, we performed different strategies of cleaning and dissociation on Drosophila melanogaster w1118 larval testes. We collected testes without protease treatment with fatbody just attached around the gonad, fatbody alone dissected from around the testes, testes without fatbody and testes dissociated by either by Papain or Trypsin and Collagenase cocktail. We prepared poly A+ RNA-Seq libraries and performed transcriptional profiling to generate 50 bp stranded single end reads.

Drosophila melanogaster late third instar larval ovary and gonadal fatbody polyA+ RNA-Seq profiling.

Project description:Here we perform transcriptional profiling of late third instar larval ovaries and gonadal fatbody from Drosophila melanogaster w1118 flies. We designed this experiment to investigate the effect of protease treatment on dissected ovaries. We profiled ovaries without protease treatment with some fatbody still attached, fatbody alone dissected from around the ovaries, ovaries cleaned of fatbody using a papain/collagenase cocktail, and ovaries dissociated using a papain/collagenase cocktail. We then constructed polyA+ libraries and performed 50 bp stranded single end RNA-Seq.

PolyA+ RNA-Seq profiling of Drosophila melanogaster late third instar larval ovary, testis and sex transformed gonads as a result of tra and dsx perturbation.

Project description:We designed this experiment to investigate the transcriptional changes in gonads as a result of sex transformation. Here we performed transcriptional profiling of the ovary transformed into testis from the tra loss of function (XX_tra_lof), testis transformed into ovary from the tra gain of function (XY_tra_gof) and ovary transformed into testis in dsxM gain of function (XX_DsxM_gof/lof) Drosophila melanogaster third instar larvae in biological quadruplicates. In addition, as controls we sequenced ovaries and testes from the female and male wildtype larvae respectively. We constructed polyA+ libraries of the gonads, cleaned off the fatbody and performed 50 bp, stranded single-end RNA-Seq.

Analysis of Drosophila melanogaster Third Instar Larval Eye and Antennal Disc Transcriptomes

Project description:The goal of this study was to examine RNA expression levels in the Drosophila larval eye and antennal discs and determine whether higher levels of transcription were correlated with the ability of transgenes to drive pairing with their homologous endogenous loci between chromosomes. Additionally, RNA expression levels were compared between the eye and antennal discs to determine whether increased insulator protein expression contributed to increased pairing in the eye disc.
