Analysis of differential gene expression in Drosophila dIME4 null mutants [single-end]

Project description:Methylation of mRNA at the N6 position of adenosin is known for a long time, but its function remains poorly understood. Here generated a null mutant in the catalytic subunit of the m6A mRNA methylosome, dIME4, in Drosophila to determine the impact of loss of m6A on gene expression using Illumina sequencing.

RNA-Seq of Drosophila melanogaster Cdk12-null mutants versus control

Project description:In a forward genetic screen, we have previously identified a null mutant of Cdk12 that results in alterations in actin dynamics, the axon initial segment and electrophysiology in Drosophila melanogaster. To decipher how Cdk12 may be having these effects, we extracted RNA from pooled Drosophila heads and compared Cdk12-null mutants to controls at the transcriptome level.

RNA-seq profiling of Drosophila larval ring glands of kdm5 null mutants

Project description:kdm5 is an essential gene in Drosophila that has critical developmental roles in the prothoracic gland cells of the larval ring gland. We performed a bulk transcriptome analysis of the larval ring gland in w[1118] (wild type) and kdm5[140] (null mutant) in order to identify genes in the prothoracic gland involved in the lethality of kdm5 null mutants. We found that the absence of kdm5 causes dysregulation of genes involved in various metabolic pathways. In particular, genes both bound by KDM5 and differentially expressed in this cell type are involved in regulation of mitochondrial biology and autophagy.

Expression profiles of dnaA null, rok null, and dnaA null; rok null mutants

Project description:To identify potential targets of co-regulation by DnaA and Rok, we compared the transcriptional profiles of dnaA null, rok null, and dnaA null rok null mutants. Because a dnaA null mutant requires an oriC- strain background, we used an oriC- oriN+ background for all strains, to allow direct comparisons.

Differential gene expression in heart tubes of hand[173] null mutants vs. w[1118]

Project description:Hand proteins belong to the highly conserved family of basic Helix-Loop-Helix transcription factors and are critical for distinct developmental processes, including cardiogenesis and neurogenesis in vertebrates. In Drosophila melanogaster a single orthologous hand gene is expressed with absence of the respective protein causing semilethality during early larval instars. Surviving adult animals suffer from shortened lifespan associated with a disorganized myofibrillar structure being apparent in the dorsal vessel, the wing hearts and in midgut tissue. Based on these data, the major biological significance of Hand seems to be related to muscle development, maintenance or function; however, up to now the physiological basis for Hand functionality remained elusive. Thus, the identification of genes whose expression is, directly or indirectly, regulated by Hand has considerable relevance with respect to understanding its biological functionality in flies and vertebrates. Beneficially, hand mutants are viable and exhibit affected tissues which renders Drosophila an ideal model to investigate up- or downregulated target genes by a comparative microarray approach focusing on the respective tissues from mutant specimens. Our present work reveals for the first time that Drosophila melanogaster Hand regulates the expression of numerous genes of diverse physiological relevancy including distinct factors required for proper muscle development and function, such as Zasp52 or Msp-300. These results relate Hand activity to muscle integrity and functionality and may thus be highly beneficial in order to understand hand phenotypes described earlier. For hand[173] null mutants and w[1118] heart tissues of wandering 3d instar larvae were dissected, RNA was isolated and samples were subjected to microarray analysis.
