Evidence for the hormonal function of a CRF-related diuretic peptide (Locusta-DP) in Locusta migratoria
Locusta-DP is a corticotropin-releasing factor (CRF)-related diuretic peptide isolated from the migratory locust Locusta migratoria. At nanomolar concentrations, synthetic Locusta-DP stimulated fluid secretion and cyclic AMP production by Malpighian tubules isolated in vitro and increased the rate of amaranth clearance in starved locusts to levels comparable with those observed during post-feed...
متن کاملDifferences in Hydrolysis and Binding of Homologous Juvenile Hormones in Locusta migratoria Hemolymph
Male Locusta hemolymph contains JH-esterase(s) and a JH-carrier protein with high affinity and low capacity that both interact enantioselectively with juvenile hormones. Exposure of racemic JH-I and JH-III results in preferential hydrolysis of the naturally configurated enantiomer of JH-I but the unnaturally configurated enantiomer of JH-III. The JH-carrier protein has a remark able specificit...
متن کاملCharacterization of the Binding of Apolipophorin Iii to Lipopolysaccharides
CHARACTERIZATION OF THE BINDING OF APOLIPOPHORIN III TO LIPOPOLYSACCHARIDES By Merve Oztug August, 2009 Apolipophorin III (apoLp-III) is a small insect apolipoprotein used as a model. Apolipoproteins neutralize lipopolysaccharides but the details are poorly understood. Lipopolysaccharides of gram negative bacteria can induce a septic shock, a common lethal condition. In the present study, the a...
متن کاملParental crowding influences life-history traits in Locusta migratoria females.
Parental environments could play an important role in controlling insect outbreaks, provided they influence changes in physiological, developmental or behavioural life-history traits related to fluctuations in population density. However, the potential implication of parental influence in density-related changes in life-history traits remains unclear in many insects that exhibit fluctuating pop...
متن کاملInnervation of the ventral diaphragm of the locust (Locusta migratoria).
1. Innervation and some electrical properties of the locust ventral diaphragm were investigated with electrophysiological and histological methods. 2. Muscle fibres are coupled electrically. Electrical stimulation evokes a graded active membrane response. 3. Each segment is innervated by four motor neurones as follows. Two motor neurones are situated in each abdominal ganglion. Branches of thei...
