Locust adipokinetic hormones mobilize diacylglycerols selectively

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2010
The diacylglycerols (DG) molecular species and their fatty acid (FA) composition were investigated by electrospray mass spectrometry (ESI-MS) and by gas chromatography with flame ionisation detection (GC-FID) in haemolymph of Locusta migratoria after application of adipokinetic hormones Locmi-AKH-I, -II and -III. The analyses showed (1) a heterogeneous

Adipokinetic Hormones: Coupling between Biosynthesis and Release

Annals of the New York Academy of Sciences, 1999
Abstract: During long‐distance flight of migratory locusts, the dramatic energy demand of the flight muscles is controlled by three adipokinetic hormones (AKHs). These peptide hormones regulate the mobilization of lipid and carbohydrate stored in the fat body to serve as energy substrates for the flight muscles.

SOLID‐PHASE SYNTHESIS OF LOCUST ADIPOKINETIC HORMONE

International Journal of Peptide and Protein Research, 1981
The synthesis of locust adipokinetic hormone by the solid‐phase method is described. The synthetic product has been shown by bioassay to possess lipid‐mobilizing activity identical to that of the natural hormone.

Adipokinetic Hormones in Locusts

1984
The actions of adipokinetic hormones are more diverse than their utilitarian name suggests. We will review here the known actions of these hormones in adult locusts to emphasise their importance in the integrated utilisation of metabolic fuels during flight.

Primary Structures of Locust Adipokinetic Hormones II

Biological Chemistry Hoppe-Seyler, 1985
Adipokinetic hormones II from corpora cardiaca of the locusts Schistocerca gregaria and Locusta migratoria, respectively, have been isolated and their primary structures elucidated. Both octapeptides are N-terminally blocked by a 5-oxoproline (pyroglutamate) residue and had to be cleaved by 5-oxoprolyl-peptidase to make them available for the Edman ...

Mass spectral signature for insect adipokinetic hormones

Rapid Communications in Mass Spectrometry, 2005
Abstract Insect adipokinetic hormones (AKHs) are structurally similar. They consist of 8 to 10 amino acid residues, and are post‐translationally modified at the N‐terminus (pyroglutamic acid) and at the C‐terminus (carboxyamide).

NMR Study of Insect Adipokinetic Hormones

Spectroscopy Letters, 2000
Abstract Mem-CC (pGlu-Leu-Asn-Tyr-Ser-Pro-Asp-Trp-NH2), Tem-HrTH (pGlu-Leu-Asn-Phe-Ser-Pro-Asn-Trp-NH2) and Del-CC (pGlu-Leu-Asn-Phe-Ser-Pro-Asn-Trp-GIy-Asn-NH2) are adipokinetic hormones, isolated from the corpora cardiaca of different insect species. These hormones regulate energy metabolism during flight and so are intimately involved in an insect's

The adipokinetic hormones of Odonata: A phylogenetic approach

Journal of Insect Physiology, 2005
Adipokinetic neuropeptides from the corpora cardiaca of the major families of all three suborders of the Odonata were identified by one or more of the following methods: (1) Isolation of the peptides from a methanolic extract of the corpora cardiaca by liquid chromatography, peak monitoring by fluorescence of the Trp residue and comparison of the ...

Adipokinetic hormone-induced antioxidant response in Spodoptera littoralis

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2012
The antioxidative potential of the Manduca sexta adipokinetic hormone (Manse-AKH) in the last instar larvae of Spodoptera littoralis (Noctuidae, Lepidoptera) was demonstrated after exposure to oxidative stress (OS) elicited by feeding on artificial diet containing tannic acid (TA).
