Methoprene modifies adipokinetic hormone characteristics in the firebug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2010
In the present study the hypothesis that there is a feedback between juvenile hormone and adipokinetic hormones (AKHs) was investigated by topical application of the juvenoid methoprene on 9-day-old adult males of the firebug Pyrrhocoris apterus.

Systemic corazonin signalling modulates stress responses and metabolism in Drosophila [PDF]

open access: yesOpen Biology, 2016
Stress triggers cellular and systemic reactions in organisms to restore homeostasis. For instance, metabolic stress, experienced during starvation, elicits a hormonal response that reallocates resources to enable food search and readjustment of ...

The Role of Peptide Hormones in Insect Lipid Metabolism

open access: yesFrontiers in Physiology, 2020
Lipids are the primary storage molecules and an essential source of energy in insects during reproduction, prolonged periods of flight, starvation, and diapause.

Effect of adipokinetic hormone on the structure and properties of lipophorin in locusts.

open access: yesJournal of Lipid Research, 1986
The reversible association of a low molecular weight hemolymph protein (mol wt 20,000 estimated by SDS-polyacrylamide gel electrophoresis) with lipophorin, following treatment with adipokinetic hormone (AKH), was demonstrated by density gradient ...

Primary role of adipokinetic hormone in the formation of low density lipophorin in locusts.

open access: yesJournal of Lipid Research, 1990
It was demonstrated that the primary action of adipokinetic hormone (AKH) is to stimulate calcium ion uptake into the fat body cell, subsequently causing the formation of diacylglycerol from triacylglycerol. Furthermore, it was also shown that AKH is not

Research Overview on Corpora Cardiaca Function of Drosophila melanogaster

open access: yesShiyan dongwu yu bijiao yixue
Taking the corpora cardiaca (CC) of Drosophila melanogaster as the central focus, this review establishes a four-dimensional framework of "development-secretion-regulation-function" to systematically summarize the core role of CC in glucose metabolic ...

Prediction of the post-translational modifications of adipokinetic hormone receptors from solitary to eusocial bees

open access: yesSociobiology, 2018
Adipokinetic hormone receptor (AKHR) was regarded as the crucial regulator of lipid consuming, but now has been renewed as a pluripotent neuropeptide G protein-coupled receptor. It has been identified in all sequenced bee genomes from the solitary to the

Population Density-Dependent Developmental Regulation in Migratory Locust

open access: yesInsects
Insect development is intricately governed by hormonal signaling pathways, yet the pivotal upstream regulator that potentiates hormone activation remains largely elusive.
