Project description:Caspase is best known as an enzyme involved in programmed cell death that is conserved in multicellular organisms. In addition to its role in cell death, caspase is emerging as an indispensable enzyme for a wide range of cellular functions, which have recently been termed as Caspase-Dependent non-lethal cellular Processes. We carefully examined the involvement of cell death signaling in tissue size determination using Drosophila wing as a model. We found that executioner caspase activity promoted wing growth independent of apoptosis. To identify the gene expression changes which account for the observed phenomena, we performed microarray analysis of wing imaginal disc upon caspase activity-inhibition by overexpressing p35. The analysis revealed the change in overall transcriptome, but not in the major tissue growth promoting signaling pathways.

Project description:Wing imaginal discs were dissected to generate body wall and wing/hinge fragments. Targets from three biological replicates of each were generated and the expression profiles were determined using Affymetrix Drosophila Genechip 1 arrays. Comparisons between the sample groups allow the identification of genes with localized expression patterns. Keywords = Drosophila, wing disc, spatially restricted transcripts Keywords: repeat sample

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/).

Project description:The outcome of Notch proliferation on proliferation depends on the context. In Drosophila wing imaginal discs Notch activation causes hyperplasia despite having localized inhibitory effects on proliferation. To understand te underlying mechanisms we have used genomic strategies to identify the Notch-Su(H) target genes during wing discs hyperplasis. these data are the results from expression profiling the RNAs from hyperplastic wing discs overexpressing Nicd. Direct comparison of third instar lavae wing imaginal disc Nicd (abxUbxFLPase; Act>y>Gal4, UAS GFP; FRT82B tubGal80 with UAS-Nicd; FRT82B) vs control (abxUbxFLPase; Act>y>Gal4, UAS GFP; FRT82B tubGal80 with FRT82B ). 4 Biological replicates, the 2nd replicate was performed as a dye-swap.

Project description:The outcome of Notch activation of proliferation depends on cellular context. In Drosophila wing discs Notch pathway overactivation results in hyperplasia. To understand the mechanisms we have used genomic strategies to indetify the Notch-S(H) target genes directly regulated in wing disc hyperplasia. These data are the results from expression profiling the RNAs from hyperplastic wing discs overexpressing Su(H). Direct comparison of Giant third instar lavae wing imaginal disc (UAS-GFP:Su(H) expressed by the patched[559.1]-Gal4 driver) vs control (UAS-NLS-GFP expressed by the patched[559.1]-Gal4 driver). 3 Biological replicates, the 3rd replicate was performed as a dye-swap.

Project description:Drosophila imaginal disc cells exhibit a remarkable ability to switch cell fates under various perturbations, a phenomenon known as transdetermination (TD). The winged eye (wge) gene induces eye-to-wing TD by its overexpression in eye imaginal discs using eye specific Gal4 driver (eyeless-Gal4). Gene network controlling this process, however, is largely unclear. Additionally, we identified that heterochromatin-related histone methyltransferase Su(var)3-9 is essential for wge-mediated TD. We used microarray to detail the global gene network underlying wge-mediated eye-to-wing TD, and the involvement of Su(var)3-9 in the gene network.
