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.

Temperature dependence of the transcriptome in cultured Drosophila S2R+ cells

Project description:Cells in ectothermic organisms often maintain homeostatic function over a considerable range of ambient temperatures. However, as temperature has pronounced effects on all biological processes, but not necessarily in a uniform manner on each of the myriad of distinct processes, cellular acclimation to ambient temperature change is predicted to involve complex regulation. To assess the effects of temperature change within the readily tolerated temperature range on the transcriptome, we have performed expression profiling with S2R+ cells, which are derived from the ectothermic organism Drosophila melanogaster.

Effects of ambient temperature on DNA accessibility in nuclear chromatin of Drosophila S2R+ cells [ATAC-seq]

Project description:Cells in ectothermic organisms often maintain homeostatic function over a considerable range of ambient temperatures. However, as temperature has pronounced effects on all biological processes, but not necessarily in a uniform manner on each of the myriad of distinct processes, cellular acclimation to ambient temperature change is predicted to involve complex regulation, including the transcriptional level. To study effects of changes in ambient temperature on chromatin accessibility, we performed ATAC-Seq with S2R+ cells, a line derived from embryos of the ectothermic organism Drosophila melanogaster. Aliquots of S2R+ cells were exposed to different temperatures (14, 25 and 29°C) within the readily tolerated range before analysis with ATAC-Seq.

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

Project description: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.

Temporal dynamics of transcriptome change in Drosophila S2R+ cells after a temperature shift from 25 to 14°C

Project description:Cells in ectothermic organisms often maintain homeostatic function over a considerable range of ambient temperatures. However, as temperature has pronounced effects on all biological processes, but not necessarily in a uniform manner on each of the myriad of distinct processes, cellular acclimation to distinct temperatures is predicted to involve complex regulation. To assess the effects of a temperature downshift from 25 to 14°C, i.e. from the optimal temperature to the lower limit of the readily tolerated range, on the transcriptome in a time-resolved manner, we have performed expression profiling with S2R+ cells, which are derived from the ectothermic organism Drosophila melanogaster.

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.
