RNA-seq of Hml-SwitchGal4 induced pathway activation in Drosophila plasmatocytes
Ontology highlight
ABSTRACT: Drosophila carrying Hml-SwitchGal4 were crossed to different uas-constructs (uas-eGFP, uas-PGRP-LC, uas-hop, uas-tkvQD). 3rd instar larvae were either kept as control or SwitchGal4 was activated by hormone feeding for 24h. Afterwards plasmatocytes were extracted and subjected to RNA-seq.
Project description:OrR drosophila 3rd instar larvae were subjected to septic injury with a mixture of E.coli and S.aureus at 3h, 6h and 18h. Plasmatocytes were isolated afterwards and subjected to RNA-seq
Project description:Drosophila plasmatocyes expressed control or trxG RNAis under the plasmatocyte specific Hml promotor. 6h prior to plasmatocyte collection animals were split into control and septic injury groups and treated accordingly. Afterwards plasmatocytes were isolated and polyA RNA was subjected to RNA-seq.
Project description:Drosophila 3rd instar larvae were subjected to septic injury. After 6h plasmatocytes were isolated, fixed and subjected to ChIP-seq.
Project description:To identify the presence of different chromatin states in homogeneous primary cells, Drosophila melanogaster plasmatocytes were isolated from 3rd instar larvae and subjected to cross-linked ChIP-seq using antibodies against a range of H3 histone modifications and PolII.
Project description:Drosophila melanogaster 3rd instar wandering larvae with a genetic construct for hemocyte ablation were collected along with genetically matched non-ablated animals, RNA was extracted from whole animals and used for RNA-seq.
Project description:The miRNA 310-311-312-313 cluster from D. melanogaster (referred to as Dm310s) and the homolog from D. pseudoobscura (Dp310s) were used to transform D. melanogaster. The over-expression of UAS-miR310s in two Dm310s transgenic lines (M1-7 and M1-3) and Dp310s transgenic line P4-18 was driven by GAL4 line NP5941 with native miR-310 expression pattern. We used Drosophila Tiling 1.0 F arrays to assess the effects of miR310s over-expression on the whole transcriptome. We compared the transcriptional profiling of Dm310s and Dp310s overexpression in D.melanogaster using double-stranded cDNA followed by bioprime random labeling, and hybridization to Affy Drosophila tiling 1.0 F array. Third-instar progeny larvae from the crosses with maternal NP5941 and paternal UAS-miR-310 cluster transgenic lines were collected and third-instar larvae from the cross with maternal NP5941 and paternal w1118 were used as control. Three biological repeats were used for each stock. A processed data matrix reporting values (log2 intensity after quantile normalization) for all of the Samples is linked below as a supplementary file.

We used DGRC-1 cDNA arrays to assess the effects of miR310s over-expression on the whole transcriptome. Direct two-colour design involving six arrays in three dye-swap pairs, with each pair used for the pairwise comparison of Dm310s, Dp310s and w1118 (control).
Project description:Gliogenesis in the Drosophila CNS occurs during embryogenesis and also during the postembryonic larval stages. Several glial subtypes are generated in the postembryonic CNS through the proliferation of differentiated glial cells. The genes and molecular pathways that regulate glial proliferation in the postembryonic CNS are poorly understood. In this study we aimed to use gene expressing profiling of CNS tissue enriched in glia to identify genes expressed in glial cells in the postembryonic CNS. We used microarrays to compare the gene expression profiles from the larval CNS of animals that had increased numbers of glial cells to identify genes that are expressed in glia. RNA was purified from the late third instar larval CNS from control larvae, or larvae expressing an activated form of the FGF receptor (Hlt[ACT]), or overexpressing the insulin receptor (InR) in glial cells using the glial specific driver repoGal4 to increase the number of glial cells and generate CNS tissue enriched in glia.
