Studies on the purification of locust adipokinetic hormone
Life Sciences, 1977Abstract 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.

The hyperglycaemic activity of locust adipokinetic hormone
Physiological Entomology, 1977ABSTRACT. 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, 1983Adipokinetic 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, 1996L-[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, 2011Adipokinetic 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.

Locust Adipokinetic Hormones: Molecular Biology of Biosynthesis
1990Adipokinetic hormone is the name given to a biological activity detectable in extracts taken from the locust corpora cardiaca, major neuroendocrine structures in insects (Mayer and Candy, 1969; Beenakkers, 1969). In recent years there has been a great deal of progress at the molecular level concerning these and related hormones in other insects and ...
