Sex determination gene transformer regulates the male-female difference in Drosophila fat storage via the adipokinetic hormone pathway

open access: yeseLife, 2021
Sex differences in whole-body fat storage exist in many species. For example, Drosophila females store more fat than males. Yet, the mechanisms underlying this sex difference in fat storage remain incompletely understood. Here, we identify a key role for

Induced hyperlipaemia and immune challenge in locusts [PDF]

open access: yes, 2004
Injections of immunogens, such as β-1,3-glucan or lipopolysaccharide (LPS), bring about a marked hyperlipaemia with associated changes in lipophorins and apolipophorin-III in the haemolymph of Locusta migratoria.

Regulation of Metabolism by an Ensemble of Different Ion Channel Types: Excitation-Secretion Coupling Mechanisms of Adipokinetic Hormone Producing Cells in Drosophila

open access: yesFrontiers in Physiology, 2020
Adipokinetic Hormone (AKH) is the primary insect hormone that mobilizes stored energy and is functional equivalent to mammalian glucagon. While most studies have focused on exploring the functional roles of AKH, relatively little is known about how AKH ...

Interactions between the endocrine and immune systems in locusts [PDF]

open access: yes, 2003
The prophenoloxidase cascade in the haemolymph of mature adult Locusta migratoria migratorioides (R & F) is activated in response to injection of laminarin, a -1,3 glucan.

Biosynthesis of adipokinetic hormones (AKHs): further characterization of precursors and identification of novel products of processing [PDF]

open access: yesThe Journal of Neuroscience, 1989
Two adipokinetic hormones (AKH I: pGlu-Leu-Asn-Phe-Thr-Pro-Asn-Trp-Gly- Thr-NH2, and AKH II: pGlu-Leu-Asn-Phe-Ser-Thr-Gly-Trp-NH2) are synthesized by the neurosecretory cells of the corpora cardiaca (CC) of the locust Schistocerca gregaria. Both AKHs are released into the blood during flight and serve to regulate lipid metabolism and other ...

Managing fuels and fluids: Network integration of osmoregulatory and metabolic hormonal circuits in the polymodal control of homeostasis in insects

open access: yesBioEssays, Volume 45, Issue 9, September 2023., 2023
Insect homeostasis relies on the coordinated release of hormones to recruit the appropriate combination of responses to restore balance. Here we discuss emerging evidence that osmotic and metabolic signals are integrated by the same hormonal circuits to provide a framework for understanding the network interactions that underlie the polymodal ...

Diversity of adipokinetic hormones in termites (Isoptera)

open access: yesEuropean Journal of Entomology, 2016
In this study we report on the structural diversity of adipokinetic hormones (AKHs) in the evolutionarily oldest group of social insects, the termites (Isoptera).

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 ...

A quantitative study of adipokinetic hormone of the firebug, Pyrrhocoris apterus [PDF]

open access: yes, 2002
The development of an enzyme-linked immunoassay (ELISA) for the adipokinetic neuropeptide hormone, Pya-AKH, from the firebug Pyrrhocoris apterus L. is described. The ELISA measures as little as 20 fmol of Pya-AKH.

An Adipokinetic Hormone Acts as a Volume Regulator in the Intertidal Gastropod Mollusk, Aplysia californica

open access: yesFrontiers in Endocrinology, 2018
Adipokinetic hormone (AKH) is a multifunctional neuropeptide in the gonadotropin-releasing hormone superfamily. In insects, AKH acts to mobilize energy stores during times of high energetic demand, but has been shown to have other effects.
