Expression data from third instar Drosophila larvae

Project description:Ectopic expression of DNMT3L in Drosophila causes melanotic tumor in the transgenic flies from fifth generation onwards. We used microaarray data analysis to look for the genes and pathways which are affected on ectopic expression of DNMT3L in Drosophila. Drosophila third instar larvae were selected at particular stages of development for RNA extraction and hybridization on Affymetrix microarrays.

Transcription profiling of Drosophila third instar larvae midgut

Project description:Oligoarray analysis was used to determine the number and nature of genes expressed in third-instar Drosophila melanogaster larval midguts. The majority of transcripts were associated with protein synthesis and metabolism. Serine proteases were the main proteolytic enzymes detected. Experiment Overall Design: Three replicates for each sample. We used Affy chip Drosophila 1.

Expression data from Drosophila third instar larvae eye imaginal discs

Project description:The kinase nmo is required for proper ommatidial rotation in the developing Drosophila compound eye. It has been suggested to regulate gene expression by phosphorylating transcription factors. We used microarray analysis to identify genes which expression is regulated by nmo during ommatidial rotation.

Expression data from control and high sugar-fed third instar Drosophila larvae

Project description:Chronic high sugar feeding induces obesity, hyperglycemia, and insulin resistance in flies and mammals. To gain insight into the mechanisms underlying this response, we profiled gene expression in chronically high sugar fed, wandering (post-prandial) third instar wild type larvae (L3). These data were compared to control-fed larvae as well as those (mid-L3) actively feeding for twelve hours on both diets. We used microarrays to detail the response of Drosophila larvae to high sugar-induced insulin resistance.

Comparison of D. simulans/D. sechellia third instar male larvae hybrid expression values to pure-species larvae parents

Project description:Species often produce sterile hybrids early in their evolutionary divergence, and some evidence suggests that hybrid sterility may be associated with deviations or disruptions in gene expression. In support of this idea, many studies have shown that a high proportion of male-biased genes are underexpressed compared to non-sex-biased genes in sterile F1 male hybrids of Drosophila species. In this study, we examined and compared patterns of misexpression in F1 hybrid male third instar larvae of Drosophila simulans and its sibling species, D. sechellia. We analyzed hybrids using custom cDNA arrays we developed from RT-PCRs of spermatogenesis-related transcripts from these species and another sibling species (D. mauritiana). The results from a commercial genome-wide array and custom chip for adults of this species pair, from the custom chip and the genome-wide chip for adults of the D. simulans-D. mauritiana species pair, and from the larvae of the D. simulans-D. mauritiana species pair, are presented separately. Keywords: Comparison of pure-species Drosophila expression to hybrid expression in larvae

DmSAS is required for sialic acid biosynthesis in cultured Drosophila third instar larvae CNS neurons.

Project description:Sialylation is an important carbohydrate modification of glycoconjugates that has been shown to modulate many cellular/molecular interactions in vertebrates. In Drosophila melanogaster (Dm), using sequence homology, several enzymes of the sialylation pathway have been cloned and their function tested in expression systems. Here we investigated whether sialic acid incorporation in cultured Dm central nervous system (CNS) neurons required endogenously expressed Dm sialic acid synthase (DmSAS). We compared neurons derived from wild type Dm larvae with those containing a DmSAS mutation (148 bp deletion). The ability of these cells to produce Sia5NAz (sialic acid form) from Ac(4)ManNAz (azide-derivatized N-acetylmannosamine) and incorporate it into their glycoconjugates was measured by tagging the azide group of Sia5NAz with fluorescent agents via Click-iT chemistry. We found that most of the wild type Dm CNS neurons incorporated Sia5NAz into their glycoconjugates. Sialic acid incorporation was higher at the soma than at the neurite and could also be detected at perinuclear regions and the plasma membrane. In contrast, neurons from the DmSAS mutant did not incorporate Sia5NAz unless DmSAS was reintroduced (rescue mutant). Most of the neurons expressed ?2,6-sialyltransferase. These results confirm that the mutation was a null mutation and that no redundant sialic acid biosynthetic activity exists in Dm cells, i.e., there is only one DmSAS. They also provide the strongest proof to date that DmSAS is a key enzyme in the biosynthesis of sialic acids in Dm CNS neurons, and the observed subcellular distribution of the newly synthesized sialic acids offers insights into their biological function.
