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).

Role of adipokinetic hormone during starvation in Drosophila

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2018
The role of adipokinetic hormone (Drome-AKH) in maintaining the levels of basic nutrients, under starvation conditions, was studied using Drosophila melanogaster mutants with AKH deficiency (Akh1) and AKH abundance (EE-Akh). Our results showed lipids as the main energy reserve in Drosophila, and their physiological level and metabolism were shown to be

Studies on the purification of locust adipokinetic hormone

Life Sciences, 1977
Abstract Locusta adipokinetic hormone (AKH) has been purified from glandular lobes of corpora cardiaca by a series of chromatographic steps that have allowed a 58 to 77% recovery of activity. Methanolic extracts of the glandular lobes were fractionated on Sephadex LH-20 and then on thin-layer plates.

Adipokinetic hormone inhibits protein synthesis in Locusta

Nature, 1979
The adipokinetic hormone (AKH) of the locust has been isolated, characterised and synthesised1,2. In this insect, its function is to mobilise diglycerides from the fat body to provide energy for sustained flight3. In addition, it modifies the metabolic activity of the flight muscles so as to oxidise fatty acids preferentially4.

The hyperglycaemic activity of locust adipokinetic hormone

Physiological Entomology, 1977
ABSTRACT. Pure adipokinetic hormone (AKH) extracted from the glandular lobes of locusts induces hyperglycaemia in cockroaches. Larger doses (20–200 pmol) of AKH are required to induce hyperglycaemia in the cockroach than are required to produce hyperlipaemia in locusts (1–20 pmol).

Locust adipokinetic hormone stimulates lipid mobilization in Manduca sexta

Biochemical and Biophysical Research Communications, 1983
Adipokinetic hormone, a decapeptide isolated from the locust, stimulates mobilization of diacylglycerols from the locust fat body and loading of the lipid transport protein, lipophorin. Injection of the synthetic locust adipokinetic hormone into a sphinx moth, Manduca sexta, causes lipid loading of lipophorin. The lipophorin decreases in density from 1.

Synthesis of [3H-pyroglutamyl1]-adipokinetic hormone-1

Journal of Labelled Compounds and Radiopharmaceuticals, 1996
L-[3,4- 3 H(N)]-Glutamine was cyclized to [ 3 H]-pyroglutamic acid and coupled with [des-pGlu 1 ]-AKH-I to give [ 3 H-pyroglutamyl 1 ]-adipokinetic hormone-I with a specific activity of 46 Ci/mmole. Results relating to stability of this product during storage are reported.

Adipokinetic hormones provide inference for the phylogeny of Odonata

Journal of Insect Physiology, 2011
Adipokinetic neuropeptides from the corpora cardiaca of 17 species of Odonata encompassing mainly the families Corduliidae and Libellulidae were isolated and structurally elucidated using liquid chromatography coupled with ion trap electrospray ionization mass spectrometry.
