Project description:Affymetrix microarray to detect changes in gene expression between lgl27S3/lglE2S31 and FRT82B larvae 4-day old 3rd instar lgl27S3/lglE2S31 larvae were compared to 0-day old 3rd instar FRT82B larvae
Project description:Single channel custom oligonucleotide array of 147 microRNAs to detect changes in expression of a lgl-hypomorph mutant versus wild-type 0, 3, and 5 day old 3rd instar lgl-hypomorph larvae were compared to 0 day 3rd instar wild-type larvae to test for differences in microRNA expression
Project description:Using RNAseq we report differentially expressed genes after knockdown of Ataxin-2 in Drosophila S2 lysate and Drosophila 3rd instar larvae brain
Project description:Total protein was isolated from the trachea and midgut of D. melanogaster 3rd instar larvae and analysed by shotgun proteomics in order to identify the putative carbohydrate-active enzymes.
Project description:Gene expression levels were determined in 3rd instar and adult Drosophila melanogaster reared during spaceflight, to elucidate the genetic and molecular mechanisms underpinning the effects of microgravity on the immune system. The goal was to validate the Drosophila model for understanding alterations of innate immune responses in humans due to spaceflight. Five containers of flies, with ten female and five male fruit flies in each container, were housed and bred on the space shuttle (average orbit altitude of 330.35 km) for 12 days and 18.5 hours, with a new generation reared in microgravity. RNA was extracted on the day of shuttle landing from whole body animals (3rd instar larvae and adults), hybridized to Drosophila 2.0 Affymetrix genome arrays, and the expression level of all genes was normalized against the gene expression level from the corresponding developmental stage animals raised on ground. Spaceflight altered the expression of larval genes involved in the maturation of plasmatocytes (macrophages) and their phagocytic response, as well as the level of constitutive expression of pattern recognition receptors and opsonins that specifically recognize bacteria, and of lysozymes, antimicrobial peptide pathway and immune stress genes, hallmarks of humoral immunity.
