Changes in lipophorins are related to the activation of phenoloxidase in the haemolymph of Locusta migratoria in response to injection of immunogens [PDF]

, 2003
In Locusta migratoria, activation of phenoloxidase in the haemolymph in response to injection of laminarin is age-dependent: being absent in fifth instar nymphs and newly emerged adults, and only becoming evident four days after the final moult.

Adipokinetic hormone enhances laminarin and bacterial lipopolysaccharide-induced activation of the prophenoloxidase cascade in the African migratory locust, Locusta migratoria [PDF]

, 2002
Lom-AKH-I enhances the activation in vivo of prophenoloxidase in the haemolymph of the African migratory locust, Locusta migratoria, in response to challenge with laminarin.

Coordinated RNA-Seq and peptidomics identify neuropeptides and G-protein coupled receptors (GPCRs) in the large pine weevil Hylobius abietis, a major forestry pest [PDF]

, 2018
Hylobius abietis (Linnaeus), or large pine weevil (Coleoptera, Curculionidae), is a pest of European coniferous forests. In order to gain understanding of the functional physiology of this species, we have assembled a de novo transcriptome of H. abietis,

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

Journal 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 ...

The proprotein convertase encoded by amontillado (amon) is required in Drosophila corpora cardiaca endocrine cells producing the glucose regulatory hormone AKH. [PDF]

PLoS Genetics, 2010
Peptide hormones are potent signaling molecules that coordinate animal physiology, behavior, and development. A key step in activation of these peptide signals is their proteolytic processing from propeptide precursors by a family of proteases, the ...

A neuronal relay mediates a nutrient responsive gut/fat body axis regulating energy homeostasis in adult Drosophila [PDF]

, 2019
The control of systemic metabolic homeostasis involves complex inter-tissue programs that coordinate energy production, storage, and consumption, to maintain organismal fitness upon environmental challenges.

High-fat diet enhances starvation-induced hyperactivity via sensitizing hunger-sensing neurons in Drosophila

eLife, 2020
The function of the central nervous system to regulate food intake can be disrupted by sustained metabolic challenges such as high-fat diet (HFD), which may contribute to various metabolic disorders.

Regulation of a Trehalose-Specific Facilitated Transporter (TRET) by Insulin and Adipokinetic Hormone in Rhodnius prolixus, a Vector of Chagas Disease

Frontiers in Physiology, 2021
Using the blood-sucking kissing bug, Rhodnius prolixus as an experimental model, we have studied the involvement of insulin-like peptides (ILPs) and adipokinetic hormone (AKH) signaling in carbohydrate metabolism, focusing on the regulation of the ...

Morin hydrate reduces survival and fertility, delays development and weakens lipid reserves in Aedes aegypti. [PDF]

Med Vet Entomol
Morin hydrate promoted mortality and reduced the rate of pupation and egg laying in Aedes aegypti larvae that survive treatment. Morin hydrate reduces the levels of triacylglycerol, the main lipid reserve in A. aegypti larvae. The expression of proteins involved in lipogenesis and lipolysis was downregulated and upregulated, respectively, in larvae ...
