Project description:Profiling of changes in steady state RNA levels upon RNAi-mediated knockdown of the nucleosome remodeling ATPase ISWI in Drosophila SL2 cells. Quantitation of the corresponding proteomes has been performed to describe transcriptome-proteome relations. The analysis indicates a limited correlation of the two expression steps. Experiment Overall Design: Drosophila SL2 cells were incubated 7 days after treatment with 10 ug of dsRNA directed against GST or ISWI, respectively. 3 biological replicates per experimental conditions have been collected.

Project description:We used microarrays to detail the global gene expression changes following RNAi knock-down of dTip60 in Drosophila SL2 cells Experiment Overall Design: We compared SL2 cells treated with dTip60-RNAi with SL2 cells mock-treated with eGFP-RNAi to determine global gene expression changes by microarray analysis
Project description:In mammalian cells, AU-rich elements (AREs) are well known regulatory sequences located in the 3' untranslated region (UTR) of many short-lived mRNAs that suppress gene expression at the posttranscriptional level. Tis11, a zinc finger RNA-binding protein homologous to mammalian tristetraprolin, targets ARE-containing reporter mRNAs for rapid degradation in SL2 cells. To identify Drosophila mRNA targets of Tis11, we performed genome-wide expression profiling after dsRNA-mediated depletion of endogenous Tis11 in SL2 cells. Furthermore, we studied the involvement of Tis11 in regulating the Drosophila immune response by profiling mRNA expression after LPS treatment, in the presence or absence of Tis11.

Furthermore, we studied the involvement of Tis11 in regulating the Drosophila immune response by profiling mRNA expression after LPS treatment, in the presence or absence of Tis11. SL2 cells were treated with either dsRNA against Tis11 or dsRNA against GFP (control). After 4 days of treatment with 12.5 microgram dsRNA / ml medium, total RNA was extracted and hybridized to Drosophila Genome 2.0 Arrays (Affymetrix, Cat. No. 900531). Where indicated, cells were treated with lipopolysaccharide (LPS, Sigma, O55:B5) at a concentration of 10 microgram / ml for 4 hours before lysis. All experiments were performed in 3 biological replicates.
