Measurement of Sleep and Arousal in Drosophila
[Abstract] Sleep is a conserved neurobehavioral state observed in animals with sufficiently complex nervous systems and is critical for survival. While the exact function of sleep remains unknown, the lack of sleep can have a range of physiological and behavioral effects. Studies in invertebrates and vertebrates have identified conserved neural mechanisms ...
Accessing Olfactory Habituation in Drosophila melanogaster with a T-maze Paradigm
[Abstract] Habituation is the process whereby perceptual changes alter the value of environmental stimuli, enabling salience filtering. This behavioral response decrement is a form of non-associative learning, where the subject learns about the stimulus and does not involve sensory adaptation, sensory or motor fatigue. The range of behavioral responses in D. ...
pNP Transgenic RNAi System Manual in Drosophila
[Abstract] Much of our knowledge about the mechanisms underlying biological processes relies on genetic approaches, whereby gene activity is reduced and the phenotypic consequences of perturbation are analyzed in detail. For functional genomic studies, a specific, systematic, and cost-effective manner is critical. Transgenic RNAi system is the top priority ...
Flip-flop Mediated Conditional Gene Inactivation in Drosophila
[Abstract] Mosaic analysis in Drosophila, an important tool to assess cellular phenotypes of mutants in an otherwise heterozygous background, relies on mitosis. Hence, it cannot be used to inactivate gene function in mitotically inactive, terminally differentiated cells such as neurons. To address this issue, we developed “Flip-flop”, a novel, ...

[Abstract] Copper-catalyzed azide-alkyne-cycloaddition (CuAAC), also known as ‘click chemistry’ serves as a technique for bio-orthogonal, that is, bio-compatible labeling of macromolecules including proteins or lipids. Click chemistry has been widely used to covalently, selectively, and efficiently attach probes such as fluorophores or biotin to small ...
flySAM Transgenic CRISPRa System Manual
[Abstract] Powerful and general methods that can enhance gene expression are useful to systematically study gene function. To date, compared with the methods in generating loss-of-function mutants, methods to achieve gain-of-function are limited. The entire field in Drosophila has relied heavily on the Gal4/UAS:cDNA overexpression system developed ...
