Apoptosis Determinants in Drosophila Melanogaster
The file named "chewsu.pdf" is the primary dissertation file. All other files ("*.mov") are supplemental files and may be viewed individually.

Avoidance learning in Drosophila melanogaster
<p>The importance of showing that Drosophila are capable of learning an instrumental response would, with the information already known from genetic studies, enable researchers to possibly isolate the genetic basis of a simple learning process and thus gain greater insight into this phenomenon. If …

Sterol requirements in Drosophila melanogaster
Sterol is an abundant component of eukaryotic cell membranes and is thought to influence membrane properties such as permeability, fluidity and microdomain formation. Drosophila is an excellent model system in which to study functional requirements for membrane sterol because, although it does not …

Lokalisierung eines Gedächtnisses bei Drosophila melanogaster
… olfaktorische Kurzzeitgedächtnis von Drosophila melanogaster in den Pilzkörpern lokalisiert ist. Zu Beginn dieser Doktorarbeit war bekannt, daß die Pilzkörper notwendig für das Geruchsgedächtnis sind. Drei unabhängige Methoden der Ablation bzw. Veränderung der biochemischen Eigenschaften der …

Expression analysis of Drosophila melanogaster microRNAs
… aufgelöste Expressionsmuster der Drosophila melanogaster miRNAs mittels Northern blot Analyse unterschiedlicher Entwicklungsstadien der Fliege untersucht. Zeitabhängige Expressionsmuster von miRNAs können zur Verifizierung vorhergesagter miRNA targets und biologischer Funktionen benutzt …

Functional Characterization of Amphiphysin in Drosophila melanogaster
… Amph function in vivo, I used Drosophila melanogaster as a model organism. I discovered that Drosophila Amph was broadly expressed throughout all developmental stages and was also highly expressed in specialized membranes such as the postsynaptic membrane at the larval neuromuscular …

Visuelle Mustererkennung und Parameterextraktion bei Drosophila melanogaster
… werden vier Parameter gefunden die Drosophila melanogaster aus visuellen Mustern extrahieren kann: Musterfläche, vertikale Position des Musterschwerpunkts, Verteiltheit und Musterausrichtung in horizontaler und vertikaler Richtung. Es ist nicht auszuschliessen, dass die Fliege weitere …

Candidate mechanosensitive transduction channels in Drosophila melanogaster
… von Gravitation und Tönen benötigt Drosophila melanogaster das Johnstonsche Organ (JO), welches ein chordotonaler Streckrezeptor ist. Es sitzt im 2ten Antennensegment und besteht aus ca. 500 mechanosensorischen Neuronen. Diese JO-Neuronen wandeln stimulus induzierte Antennenbewegungen in …

Extracellular matrix protein receptors in Drosophila melanogaster
… developmental consequences in Drosophila melanogaster. The remainder of this work deals with three Drosophila homologs of vertebrate proteins that may interact with integrins, a family of cell surface receptors for extracellular matrix ligands. The three integrin-interacting proteins are …

The inducible antiviral immune response of Drosophila melanogaster
In der vorliegenden Arbeit wurde Drosophila melanogaster als Modell ge- nutzt, um die angeborene Immunantwort gegen virale Infektionen zu studie- ren. Wir untersuchten mit Hilfe von genomweiten microarrays das Transkriptom von Fliegen, welche entweder mit dem Drosophila C Virus (DCV), dem Flock- …

Analyse des meiotischen Cohesinkomplexes in Drosophila melanogaster-Weibchen
… Funktion in der weiblichen Meiose von Drosophila melanogaster innehat. Im zweiten Teil der Arbeit wurden Funktionsanalysen eines weiteren Proteins (SOLO; sisters-on-the-loose) durchgeführt, für das bereits kohäsive Funktionen während der Meiose beschrieben wurden. Um zu testen, ob dieses Protein …

Causes of Naive Ethanol Avoidance in Drosophila Melanogaster
BACKGROUND: Alcohol dependence is a pressing public health concern, yet little is still known about its molecular causes. Although current studies have started to understand human addiction, Drosophila research is used as a tool to carry out more genetic and behavioral approaches that are crucial …

Time-Restricted Feeding Extends Longevity in Drosophila Melanogaster
… shown to improve cardiac health in Drosophila melanogaster, reduce metabolic markers in rodent models, and reduce glycemic indices in prediabetic men. However, the mechanism and long-term effects of this intervention remain elusive. To understand the effect of TRF on longevity we used the fruit …

Control of perineurial glial growth in Drosophila melanogaster
Although intercellular communication within peripheral nerves is critical to the structure and function of the nervous system, it is incompletely understood. Drosophila peripheral nerves comprise motor and sensory axons bundled by peripheral glia (Schwann cells) and wrapped by perineurial glia …

Modeling human Usher syndrome during Drosophila melanogaster development
… well understood. Here, I identified Drosophila melanogaster genes related to human Usher syndrome and characterized some of them (Cad99C, DSANS and crinkled) during Drosophila development, in the processes of microvilli morphogenesis in the follicular and wing imaginal disc epithelia. Cadherin …

Antimicrobial activity in cultures of female Drosophila Melanogaster
… cultures of the vinegar fly Drosophila melanogaster, fly food from mated female cultures show reduced microbial growth compared to food from male cultures. We confirmed this, hypothesising that the disparity may be due to the presence of small molecule antimicrobials secreted by female …

Investigating neuronal mitochondrial DNA loss in Drosophila melanogaster
… have used the fruitfly, Drosophila melanogaster, to study how loss of mtDNA affects neuronal function. We find that both ubiquitous RNAi and overexpression of the mtDNA binding protein TFAM causes reduced mtDNA content and lethality. TFAM RNAi or overexpression specifically in motor …

Identifizierung und Charakterisierung von Histonmethyltransferasen in Drosophila melanogaster
… die Einbeziehung des Modellsystems Drosophila melanogaster in die Erforschung der Funktionen der Histonmethylierung, für ein besseres Verständnis der epigenetischen Aktivierung und erweitert die Komplexität des „Histoncodes“.
