Octopamine in Male Aggression of Drosophila [PDF]

Current Biology, 2008
In mammals and humans, noradrenaline is a key modulator of aggression. Octopamine, a closely related biogenic amine, has been proposed to have a similar function in arthropods. However, the effect of octopamine on aggressive behavior is little understood.An automated video analysis of aggression in male Drosophila has been developed, rendering ...

Coumarin‐Based Octopamine Phototriggers and their Effects on an Insect Octopamine Receptor

ChemBioChem, 2012
AbstractWe have developed and characterized efficient caged compounds of the neurotransmitter octopamine. For derivatization, we introduced [6‐bromo‐8‐(diethylaminomethyl)‐7‐hydroxycoumarin‐4‐yl]methoxycarbonyl (DBHCMOC) and {6‐bromo‐7‐hydroxy‐8‐[(piperazin‐1‐yl)methyl]coumarin‐4‐yl}methoxycarbonyl (PBHCMOC) moieties as novel photo‐removable protecting

Differences in the phototaxis of pollen and nectar foraging honey bees are related to their octopamine brain titers

Frontiers in Physiology, 2014
The biogenic amine octopamine is an important neuromodulator, neurohormone and neurotransmitter in insects. We here investigate the role of octopamine signaling in honey bee phototaxis.

Octopamine Drives Endurance Exercise Adaptations in Drosophila

Cell Reports, 2017
Summary: Endurance exercise is an effective therapeutic intervention with substantial pro-healthspan effects. Male Drosophila respond to a ramped daily program of exercise by inducing conserved physiological responses similar to those seen in mice and ...

Octopaminergic agonists for the cockroach neuronal octopamine receptor

Journal of Insect Science, 2003
The compounds 1-(2,6-diethylphenyl)imidazolidine-2-thione and 2-(2,6-diethylphenyl)imidazolidine showed the almost same activity as octopamine in stimulating adenylate cyclase of cockroach thoracic nervous system among 70 octopamine agonists, suggesting ...

Octopamine and adrenergic-like octopamine receptors in Ixodes ricinus salivary glands

The neurotransmitter octopamine, a structural and functional analogue of the vertebrate adrenaline,plays essential roles in various aspects of invertebrate physiology. Here, using in silico approacheswe identified that in tick genomes two types of adrenergic-like octopamine and two types oftyramine receptors are present.

Octopamine modulates insect mating and Oviposition

, 2022
The neuro-mechanisms that regulate insect reproduction are not fully understood. Biogenic amines, including octopamine, are neuromodulators that have been shown to modulate insect reproduction in various ways, e.g., promote or inhibit insect mating or ...

Dopamine modulates acetylcholine release via octopamine and CREB signaling in Caenorhabditis elegans. [PDF]

PLoS ONE, 2013
Animals change their behavior and metabolism in response to external stimuli. cAMP response element binding protein (CREB) is a signal-activated transcription factor that enables the coupling of extracellular signals and gene expression to induce ...

Hearing of malaria mosquitoes is modulated by a beta-adrenergic-like octopamine receptor which serves as insecticide target

Nature Communications, 2023
Malaria mosquitoes acoustically detect their mating partners within large swarms that form transiently at dusk. Indeed, male malaria mosquitoes preferably respond to female flight tones during swarm time.

Comparison of the Effects of Octopamine and Noradrenaline on Feeding and Sleep-like Behaviour in Fasted Chicks

The Journal of Poultry Science, 2002
Octopamine, an important neurotransmitter in invertebrates, has noted several similarities with noradrenaline (NA) in mammals. To compare the effect of octopamine and NA in the central nervous system, food intake and categorized postures of fasted chicks
