Ex vivo Follicle Rupture and in situ Zymography in Drosophila

Authors: Elizabeth M Knapp, Lylah D Deady and Jianjun Sun, date: 05/20/2018, view: 305, Q&A: 0

[Abstract] Ovulation, the process of releasing a mature oocyte from the ovary, is crucial for animal reproduction. In order for the process of ovulation to occur, a follicle must be fully matured and signaled to rupture from the ovary. During follicle rupture in both mammals and Drosophila, somatic follicle cells are enzymatically degraded to allow ...

A Method to Injure, Dissect and Image Indirect Flight Muscle of Drosophila

Authors: Kunal Chakraborty, K. VijayRaghavan and Rajesh Gunage, date: 05/20/2018, view: 687, Q&A: 0

[Abstract] Inducing an injury specifically to Drosophila flight muscles is a difficult task, owing to the small size of the muscles and the presence of the cuticle. The protocol described below provides an easy and reproducible method to induce injury in the Drosophila flight muscles.

Flight and Climbing Assay for Assessing Motor Functions in Drosophila

Authors: Steffy B Manjila and Gaiti Hasan, date: 03/05/2018, view: 678, Q&A: 0

[Abstract] Motor control requires the central nervous system to integrate different sensory inputs and convey this information to the relevant central pattern generator for execution of motor function through motor neurons and muscles. Proper motor control is essential for any mobile organism to survive and interact with the external environment. For flying ...

Terminal Deoxynucleotidyl Transferase Mediated Production of Labeled Probes for Single-molecule FISH or RNA Capture

Authors: Imre Gaspar, Frank Wippich and Anne Ephrussi, date: 03/05/2018, view: 779, Q&A: 0

[Abstract] Arrays of short, singly-labeled ssDNA oligonucleotides enable in situ hybridization with single molecule sensitivity and efficient transcript specific RNA capture. Here, we describe a simple, enzymatic protocol that can be carried out using basic laboratory equipment to convert arrays of PCR oligos into smFISH and RAP probesets in a ...

Assaying Thermo-nociceptive Behavior in Drosophila Larvae

Authors: Meike Petersen, Federico Tenedini, Nina Hoyer, Fritz Kutschera and Peter Soba, date: 02/20/2018, view: 627, Q&A: 0

[Abstract] Thermo-nociception, the detection and behavioral response to noxious temperatures, is a highly conserved action to avoid injury and ensure survival. Basic molecular mechanisms of thermal responses have been elucidated in several model organisms and are of clinical relevance as thermal hypersensitivity (thermos-allodynia) is common in neuropathic ...

Assaying Mechanonociceptive Behavior in Drosophila Larvae

Authors: Nina Hoyer, Meike Petersen, Federico Tenedini and Peter Soba, date: 02/20/2018, view: 678, Q&A: 0

[Abstract] Drosophila melanogaster larvae have been extensively used as a model to study the molecular and cellular basis of nociception. The larval nociceptors, class IV dendritic arborization (C4da) neurons, line the body wall of the animal and respond to various stimuli including noxious heat and touch. Activation of C4da neurons results in a ...

Determination of DNA Damage in the Retina Photoreceptors of Drosophila

Authors: Damulewicz Milena and Pyza Elzbieta, date: 02/05/2018, view: 560, Q&A: 0

[Abstract] The retina is sensitive for light damages, because of direct light exposure, especially intense blue and UV light, which increase level of ROS and other toxic phototransduction products in photoreceptor cells. In our previous work (Damulewicz et al., 2017a and 2017b), we used 8-oxo-deoxyguanosine (8-OHdG) as a marker for oxidative stress ...

In vivo Assessment of Intestinal Permeability in Multiple Model Organisms

Authors: Raquel R. Martins, Andrew W. McCracken, Mirre J. P. Simons, Catarina M. Henriques and Michael Rera, date: 02/05/2018, view: 1290, Q&A: 0

[Abstract] The Smurf Assay (SA) was initially developed in the model organism Drosophila melanogaster where a dramatic increase of intestinal permeability has been shown to occur during aging (Rera et al., 2011). We have since validated the protocol in multiple other model organisms (Dambroise et al., 2016) and have utilized the ...

Preparation of Precisely Oriented Cryosections of Undistorted Drosophila Wing Imaginal Discs for High Resolution Confocal Imaging

Authors: Samuel Petshow and Marcel Wehrli, date: 02/05/2018, view: 845, Q&A: 0

[Abstract] The combination of immunofluorescence and laser scanning confocal microscopy (LSM) is essential to high-resolution detection of molecular distribution in biological specimens. A frequent limitation is the need to image deep inside a tissue or in a specific plane, which may be inaccessible due to tissue size or shape. Recreating high-resolution 3D ...

Drosophila Model of Leishmania amazonensis Infection

Authors: Kendi Okuda and Neal Silverman, date: 12/05/2017, view: 1033, Q&A: 0

[Abstract] This protocol describes how to generate and harvest antibody-free L. amazonensis amastigotes, and how to infect adult Drosophila melanogaster with these parasites. This model recapitulates key aspects of the interactions between Leishmania amastigotes and animal phagocytes.
