Effect of mago nashi depletion on gene expression in Drosophila S2R+ cells

ABSTRACT: This study was designed to identify changes in gene expression resulting from depletion of Mago nashi (Mago), a core subunit of the exon junction complex. Drosophila S2R+ cells were treated with double-stranded RNA targeting either LacZ or Mago for 6 days. Poly(A)+ RNA was purified from each sample and sequenced using 54 bp reads on an Illumina Genome Analyzer II. Fold changes in expression were calculated for each gene as the ratio of the reads per kilobase per million reads (RPKM) for Mago relative to LacZ. In other experiments, we have shown that Mago is required for correct splicing of the MAP kinase gene and its depletion causes a large reduction in MAP kinase mRNA levels. MAP kinase is a large gene in heterochromatin. In this study, we find that heterochromatic genes are disproportionately down-regulated in Mago-depleted cells, and those with large introns are particularly likely to be affected. SRA accession number: SRP003001.1

Effect of histone H2Av depletion on temperature dependence of the Drosophila S2R+ cell transcriptome

Project description:The histone H2A variant H2A.Z has a crucial role in the regulation of temperature-dependent gene expression in the plant Arabidopsis thaliana. To evaluate whether the Drosophila homolog histone H2Av has a similar role in the control of the transcriptional response to temperature change, we depleted this histone variant by RNA interference in S2R+ cells and analyzed the effect on the transcriptome after temperature shifts to different temperatures (14, 25 and 30°C). For control, we performed analogous experiments using treatment with lacZ dsRNA instead of His2Av dsRNA.

Time-series analysis of transcription factor knockdown in Drosophila S2R+ cells using RNA-Seq.

Project description:To understand how RNAi depletion of transcription factors impact the Drosophila transcriptome, we performed selective knockdown of 46 transcription factors in Drosophila S2R+ cell line. We treated cells with long double strand RNAs by bathing for 1 to 3 days. We purified polyA+ RNA and prepared strand-specific RNA-Seq libraries. We quantitatively measured transcriptomic responses using a time series analysis.

Time series RNA-seq analyses of Drosophila S2R+ cells after insulin stimulation

Project description:Purpose: identifying genes responding to insulin stimulation in S2R+ cells through whole transcriptome RNA-seq analyses Methods: Total RNA was extracted from S2R+ cells using TRIzol® reagent (Invitrogen). After assessing RNA quality with an Agilent Bioanalyzer, libraries were constructed with Illumina TruSeq mRNA Library Prep Kit , libraries were sequenced using an Illumina HiSeq 4000 at the Columbia Genome Center (http://systemsbiology.columbia.edu/genome-center). Results: Using an time series data analysis workflow incorporating polynormials , we identified 1254 temproally differentially expressed genes responding to insulin stimulation in the S2R+ cells.

ChIP-seq using a Dp1 antibody in Drosophila S2R+ cells

Project description:Here we report the identification of genomic regions of DNA bound by Dp1 in Drosophila S2R+ cells. Dp1 is a dimerization partner of several E2F transcription factors and is needed for E2F target promoter binding. We find that Dp1 binds the promoter regions of genes important for oxidative phosphorylation. This result is important since our data demonstrates that expression of several oxidative phosphorylation genes is down-regulated in dDP mutant Drosophila 3rd instar larval eye imaginal discs. These ChIP-seq results suggest that the mechanism by which dDP regulates expression of these genes is direct. In addition, we have confirmed a number of these Dp1 bound gene promoters by conventional Chromatin Immunoprecipitation. Examination of Dp1 bound regions of genomic DNA in S2R+ cells.
