Transcriptional profiling of Drosophila wing pouch following CR32027 RNAi

Project description:The eukaryotic cell cycle, driven by both transcriptional and post-translational mechanisms, is the central molecular oscillator underlying tissue growth throughout animals. While genome-wide studies have investigated cell cycle-associated transcription in unicellular systems, global patterns of periodic transcription in multicellular tissues remain largely unexplored. Here we define the cell cycle-associated transcriptome of the developing Drosophila wing epithelium and compare it with that of cultured Drosophila S2 cells, revealing a core set of periodic genes as well as a surprising degree of context-specificity in periodic transcription. We further employ RNAi-mediated phenotypic profiling to define functional requirements for over 300 periodic genes, with a focus on those required for cell proliferation in vivo. Finally, we investigate the role of novel genes required for interkinetic nuclear migration. Combined, these findings provide a global perspective on cell cycle control in vivo, and highlight a critical need to understand the context-specific regulation of cell proliferation. Two RNAi lines of CR32027, a non-coding RNA gene identified in this study, are examined for transcriptional changes relative to wt. Transcriptional profiles of two RNAi knockdowns, CR32027-IR1 and CR32027-IR2, are examined in Drosophila wing pouch relative to OreR wt in triplicate by RNA Seq.

The exon junction complex regulates the splicing of cell polarity gene dlg1 to control Wingless signaling in development

Project description:Wingless (Wg)/Wnt signaling is conserved in all metazoan animals and plays critical roles in development. The Wg/Wnt morphogen reception is essential for signal activation, whose activity is mediated through the receptor complex and a scaffold protein Dishevelled (Dsh). We report here that the exon junction complex (EJC) activity is indispensable for Wg signaling by maintaining an appropriate level of Dsh protein for Wg ligand reception in Drosophila. Transcriptome analyses in Drosophila wing imaginal discs indicate that the EJC controls the splicing of the cell polarity gene disc large 1 (dlg1), whose coding protein directly interacts with Dsh. Genetic and biochemical experiments demonstrate that Dlg1 protein acts independently from its role in cell polarity to protect Dsh protein from lysosomal degradation. More importantly, human orthologous Dlg protein is sufficient to promote Dvl protein stabilization and Wnt signaling activity, thus revealing a conserved regulatory mechanism of Wg/Wnt signaling by Dlg and EJC. whole transcriptome RNA-seq to examine mRNAs extracted from wildtype (i.e. overexpressing lacZ) and pre-EJC-defective (i.e. overexpressing tsu RNAi) wing discs, respectively.

Genome-wide chromatin analysis of wing imaginal discs

Project description:We report the relationship between 'absent, small or homeotic discs 2' (ASH2) occupancy, histone modifications and the transcription machinery using the wing disc as a source of chromatin. Our results indicate that genes related to development and transcriptional regulation are direct targets of ASH2 and that this protein contributes to H3K4me3 of nearby nucleosomes. Moreover, ASH2 occupancy correlates with phosphorylated forms of RNA polymerase II and histone positive marks in active genes. RNA Pol II phosphorylation in Ser5 is reduced in ash2 mutants, indicating that ASH2 plays a role in promoter stalling. Examination of three histone modifications and two polymerase modifications in wing imaginal dics cells.

Microarray comparison of anterior and posterior Drosophila wing imaginal disc cells

Project description:Signaling between cells in the Anterior (A) and Posterior (P) compartments directs Drosophila wing disc development and is dependent on expression of the homeodomain transcription factor Engrailed (En) in P cells. Downstream of en, posteriorly expressed Hedgehog (Hh) protein signals across the A/P border to establish a developmental organizer that directs pattern formation and growth throughout the wing primordium. Here we extend investigations of the processes downstream of en by using expression array analysis to compare A and P cells. 102 candidate genes were identified that express differentially in the A and P compartments; four were characterized: Stubble (Sb) expression is restricted to A cells due to repression by en. CG15905, CG16884, and CG10200/hase und igel (hui) are expressed in A cells downstream of Hh signaling; and RNA interference for hui, Stubble, and CG16884 revealed that each is essential to wing development. We carried out a global screen for genes with compartment-specific expression using expression array hybridization to compare transcript levels in A and P wing disc cells. GFP-labeled wing imaginal discs (ptc-Gal4/UAS-GFP and hh-Gal4/UAS-GFP) were micro-dissected under a fluorescence dissecting microscope. RNA isolation, amplification and microarray procedures were previously described (Klebes et al., 2002; Klebes et al., 2005; Klebes and Kornberg, 2008). In brief, hybridization probes were generated by two rounds of T7-catalyzed linear RNA amplification and labeled with Cy3 and Cy5 dyes. Reciprocally labeled probes (M-bM-^@M-^Xdye flipM-bM-^@M-^Y) were hybridized to custom produced glass microarrays (GPL2581) that contained approximately 14,000 100-600 bp exon sequences that were generated by PCR. Signal intensities were collected with a GenePix 4000B Scanner and processed with GenePix software (Molecular Devices) and global median normalized with NOMAD (http://ucsf-nomad.sourceforge.net/).
