Abstract Neuroparsins were originally identified in locust corpus cardiacum extracts as folliculostatic or ‘antigonadotropic’ neuropeptides. This paper presents the cloning of two different neuroparsin precursor cDNAs from brain desert locust, Schistocerca gregaria . The first transcript encodes ( Scg ‐NPP1) S. A and B, whereas second codes for a novel neuroparsin‐related peptide ‐NPP2). Both precursors display significant sequence similarities with each other Locusta migratoria Lom ‐NPP)...

Abstract The effects of neuroparsins on hemolymph trehalose and lipid levels total glycogen content were analyzed in Locusta migratoria . Saline methanol extracts the two lobes corpora cardiaca assayed. Neuroparsins (A B) demonstrated to be hypertrehalosemic hyperlipemic proteins neural lobe. Both these metabolic activities somewhat less potent than those adipokinetic hormone (AKH). Neuroparsin activity could distinguished from AKH by blockage with an antiserum specific neuroparsin. response...

Interaction with the environment appears necessary for maturation of sensorimotor and cognitive functions in early life. In rats, a model restriction (SMR) from postnatal day 1 (P1) to P28 has shown that low atypical activities induced perturbation motor behavior due muscle weakness functional disorganization primary somatosensory cortices. present study, our objective was understand how SMR affects muscle–brain dialogue. We focused on irisin, myokine secreted by skeletal muscles response...

Summary Corpora cardiaca (CC) of the migratory locust contain two antidiuretic (AD) factors increasing fluid reabsorption isolated recta over a 5-h period. They are contained in storage lobes (SL) and glandular (GL) CC. differ size can be separated from each other different ways (extraction, dialysis, electrophoresis). The AD factor GL CC is stable at 4°C quickly destroyed 100°C. It stimulates dose-dependent manner. Its release into haemolymph seems to controlled by octopamine, which...

The cDNA encoding neuroparsin A, a polytropic neurohormone of the locust, Locusta migratoria, was inserted into genome Autographa californica nuclear polyhedrosis virus such that transcription under control p10 promoter. A polypeptide having same charge and apparent molecular weight as authentic reactive against immune serum produced in recombinant virus-infected lepidopteran cell lines but not cells. baculovirus-expressed purified by two steps liquid chromatography (anion exchange reversed...
