Résumé :

In order to recover new mutant alleles of the Polycomb group gene Additional sex combs (Asx), mutagenized chromosomes were screened over the putative Asx allele XT129. Thirteen new mutant strains that fail to complement XT129 were recovered. Unexpectedly, the thirteen strains sorted into four complementation groups. Recombination mapping suggests that each complementation group represents a separate locus. The largest group fails to complement a deletion of Asx and maps in the vicinity of 2-72, the published location of Asx. All new mutant strains enhance the phenotype of Polycomb mutant flies

Résumé :

Errata pasted onto back page. Bibliography: p. 133-149. The RhoGEF activity of PBL is shown to be acting predominantly by the activation of Rho1 and downstream signaling pathways required for contractile ring function during cytokinesis. Genetic evidence suggests this could be through the activation of Diaphanous (an FH protein) to reorganize the actin cytoskeleton, as well as through the activation of Rho-kinase which results in the phosphorylation, and activation of myosin. Highlights a possible role for PBL during contractile ring function at a later stage that previously thought. Genetic

Résumé :

Translational control is an important means of regulating gene expression. Development of the Drosophila germ line relies on translational regulation to differentially express maternal mRNAs, allowing it to develop distinctly from the soma. One of the critical factors required for germ cell development and function is the conserved DEAD-box RNA helicase Vasa (Vas). The research presented in this thesis examines the role of Vas in translational regulation during Drosophila germ line development. A two-hybrid screen conducted with Vas identified a translation initiation factor eIF5B (dIF2

Résumé :

DRMT4 (Drosophila Arginine MethylTransferase 4) is an arginine methyltransferase in Drosophila (Boulanger et al. 2004). It shows the highest identities with mammalian PRMT4/CARM1 (Protein Arginine MethylTransferase 4) (59% identity, 75% similarity). HPLC analysis demonstrated that DRMT4 belongs to the type I class of methyltransferases (Boulanger et al. 2004), meaning that DRMT4 catalyzes asymmetrical dimethylarginine formation. A polyclonal antibody against DRMT4 was generated and used to study DRMT4 expression using western blots and immunostainings. In order to study DRMT4 function

Résumé :

ADAR is an adenosine deaminase that acts on dsRNA. Once bound to dsRNA, ADAR deaminates specific adenosines into inosines. If this occurs within the coding region of a transcript the inosine will be read as a guanosine. This can lead to a change in the amino acid at this position and increase protein diversity. In mammals there are three ADAR genes: ADAR1, ADAR2 and ADAR3. However, only ADAR1 and ADAR2 have been shown to be enzymatically active. ADAR1 is widely expressed and can edit both coding RNA and non-coding RNA. ADAR2 is restricted to the CNS and the key transcript that it edits encodes

Résumé :

Aggression is a key component of the normal repertoire of behaviours in a broad range of animals from insects to mammals. Although the genetic basis for aggression is widely accepted, only a few individual candidate genes have been studied. Recent studies have indicated that Drosophila melanogaster can serve as a powerful model system to study the genetics of aggression. The aim of this project was to identify genes associated with aggression by global profiling of the fly transcriptome using DNA expression microarrays. At the core of this study was a behavioural screen in which the aggression

The localization of oskar and nanos mRNAs is closely related to their translational activation. We provide evidence here by in vitro biochemical assays that Vasa protein is an ATP-de

Résumé :

Patterning of the Drosophila eggshell requires the induction of dorsal fates in the follicular epithelium of the ovary, which will secrete this eggshell. These fates are induced by the localized activation of epidermal growth factor (Egfr) signaling mediated by its localized ligand Gurken (Grk), which restricts the acquisition of dorsal fates to the dorsal anterior domain of the epithelium. The generation of the complex pattern of fates along the dorsal-ventral (DV) axis has been proposed to be generated by the induction of a second round of Egfr signaling in the follicular epithelium by the l

The indiscriminate action of reactive oxygen species (ROS), if left unregulated, has long been considered contributory to a range of disease processes within the animal kingdom and is also a factor associated with ageing. Consequently modifying the molecular mechanisms that regulate ROS levels may prove therapeutic and could also positively affect longevity. One of the key components of this machinery is the superoxide dismutase (SOD) family of enzymes which regulate ROS levels by scavenging the ROS superoxide. Mammals have three distinct SOD enzymes each responsible for managing superoxide le

A general form of this sequence, TNNCT was found associated with other Drosophila tRNA genes which showed high ill vitro transcription efficiency.

Behaviors are complex traits, which exhibit continuous phenotypic variation in natural populations. The continuous variation is attributable to the segregation of multiple interacting loci with individually small effects on behavior, which are sensitive to the environment.

The diversity of animal shapes and sizes, colors and textures, or behaviors and habitats all depend on specialized cells. A newly fertilized embryo must build all these specialized cell types, a process called differentiation. Much of differentiation depends on appropriately turning genes on and off in each cell type. Cell type specific control of gene expression is encoded in a type of regulatory DNA called enhancers. I am interested in how enhancers control the cell type specific gene expression that enables specialized cell functions. Enhancers read in information from regulatory proteins
