Direct linkHonda, Takato – Learning & Memory, 2022
Neural network dynamics underlying flexible animal behaviors remain elusive. The fruit fly "Drosophila" melanogaster is considered an excellent model in behavioral neuroscience because of its simple neuroanatomical architecture and the availability of various genetic methods. Moreover, "Drosophila" larvae's transparent body…

Shan, Jianying; Shen, Jie; Dong, Li; Xu, Yifan; Li, Honglin; Zhong, Lichao; Tang, Hao – Journal of Biological Education, 2023
Human ageing and age-associated diseases are among the greatest challenges and financial burdens faced by developed countries. Unfortunately, undergraduate students often do not experience any laboratory training in ageing research in the current laboratory curriculum of majors in biology, biotechnology, or medicine. In this study, we developed…

Bargiela, Ariadna; Artero, Ruben – Biochemistry and Molecular Biology Education, 2021
Laboratory practical sessions are critical to scientific training in biology but usually fail to promote logical and hypothesis-driven reasoning and rely heavily on the teacher's instructions. This paper describes a 2-day laboratory practicum in which students prepare and analyze larval cuticle preparations of "Drosophila" segmentation…

Wong, J. Y. Hilary; Wan, Bo Angela; Bland, Tom; Montagnese, Marcella; McLachlan, Alex D.; O'Kane, Cahir J.; Zhang, Shuo Wei; Masuda-Nakagawa, Liria M. – Learning & Memory, 2021
Discrimination of sensory signals is essential for an organism to form and retrieve memories of relevance in a given behavioral context. Sensory representations are modified dynamically by changes in behavioral state, facilitating context-dependent selection of behavior, through signals carried by noradrenergic input in mammals, or octopamine (OA)…

Mancini, Nino; Hranova, Sia; Weber, Julia; Weiglein, Alice; Schleyer, Michael; Weber, Denise; Thum, Andreas S.; Gerber, Bertram – Learning & Memory, 2019
Adjusting behavior to changed environmental contingencies is critical for survival, and reversal learning provides an experimental handle on such cognitive flexibility. Here, we investigate reversal learning in larval "Drosophila." Using odor-taste associations, we establish olfactory reversal learning in the appetitive and the aversive…

Weiglein, Alice; Gerstner, Florian; Mancini, Nino; Schleyer, Michael; Gerber, Bertram – Learning & Memory, 2019
Animals of many species are capable of "small data" learning, that is, of learning without repetition. Here we introduce larval "Drosophila melanogaster" as a relatively simple study case for such one-trial learning. Using odor-food associative conditioning, we first show that a sugar that is both sweet and nutritious…

The Fly-CURE is a genetics-focused multi-institutional Course-Based Undergraduate Research Experience (CURE) that provides undergraduate students with hands-on research experiences within a course. Through the Fly-CURE, undergraduate students at diverse types of higher education institutions across the United States map and characterize novel…

Baggett, Vincent; Mishra, Aditi; Kehrer, Abigail L.; Robinson, Abbey O.; Shaw, Paul; Zars, Troy – Learning & Memory, 2018
Animals in a natural environment confront many sensory cues. Some of these cues bias behavioral decisions independent of experience, and action selection can reveal a stimulus-response (S-R) connection. However, in a changing environment it would be a benefit for an animal to update behavioral action selection based on experience, and learning…

Munn, Bethany; Ericson, Brad; Carlson, Darby J.; Carlson, Kimberly A. – Bioscene: Journal of College Biology Teaching, 2015
A single fly RT-PCR protocol has recently been developed to detect the presence of the persistent, horizontally transmitted Nora virus in "Drosophila." Wild-caught flies from Ohio were tested for the presence of the virus, with nearly one-fifth testing positive. The investigation presented can serve as an ideal project for biology…

Kleber, Jörg; Chen, Yi-Chun; Michels, Birgit; Saumweber, Timo; Schleyer, Michael; Kähne, Thilo; Buchner, Erich; Gerber, Bertram – Learning & Memory, 2016
Synapsin is an evolutionarily conserved presynaptic phosphoprotein. It is encoded by only one gene in the "Drosophila" genome and is expressed throughout the nervous system. It regulates the balance between reserve and releasable vesicles, is required to maintain transmission upon heavy demand, and is essential for proper memory function…

Yu, Dinghui; Tan, Ying; Chakraborty, Molee; Tomchik, Seth; Davis, Ronald L. – Learning & Memory, 2018
The evolutionarily conserved Elongator Complex associates with RNA polymerase II for transcriptional elongation. Elp3 is the catalytic subunit, contains histone acetyltransferase activity, and is associated with neurodegeneration in humans. Elp1 is a scaffolding subunit and when mutated causes familial dysautonomia. Here, we show that…

Choi, Annette; Wang, Mengqi; Hrizo, Stacy; Buckley, Martin S. – Biochemistry and Molecular Biology Education, 2018
Exposure of organisms to high temperatures and various chemical and physical stressors can cause protein misfolding and aggregation. In turn, this can disrupt the functions of proteins, threatening both development and homeostasis. To overcome this, cells can initiate the highly conserved heat shock (HS) stress response pathway. In eukaryotes,…

This work describes the development and evaluation of a two-session laboratory class based on Tet-on technology and sex determination in the fruit fly "Drosophila melanogaster." The Tet-on system allows conditional control of gene expression, when doxycycline is applied. A laboratory exercise has been developed to illustrate how the…

The initial phase of the COVID-19 pandemic changed the nature of course delivery from largely in-person to exclusively remote, thus disrupting the well-established pedagogy of the Genomics Education Partnership (GEP; https://www.thegep.org). However, our web-based research adapted well to the remote learning environment. As usual, students who…

It has been noted that undergraduate project-based laboratories lead to increased interest in scientific research and student understanding of biological concepts. We created a novel, inquiry-based, multiweek genetics research project studying Ptpmeg, for the Introductory Biology Laboratory course at Brandeis University. Ptpmeg is a protein…
