...-instar nymphs hatched from the eggs laid by females injected with dsRNA for eclosion hormone (dsEH), crustacean cardioactive peptide (dsCCAP) and dsOKA died at the expected time of ecdysis, indicating the crucial involvement of these genes in post-embryonic development. No phenotypes were observed upon...

...Tania Y. Estévez-Lao; Dacia S. Boyce; Hans-Willi Honegger; Julián F. Hillyer SUMMARY Crustacean cardioactive peptide (CCAP) is a highly conserved arthropod neurohormone that is involved in ecdysis, hormone release and the modulation of muscle contractions. Here, we determined the CCAP gene...

... the CG while AST-3 strongly inhibited its motor output. We also studied the actions of other peptides and small molecule transmitters known to be present in C. borealis . Dopamine, serotonin, proctolin, crustacean cardioactive peptide(CCAP), a number of extended FLRFamide peptides, and cholinergic...

...J. S. Chung; D. C. Wilcockson; N. Zmora; Y. Zohar; H. Dircksen; S. G. Webster SUMMARY Full-length cDNAs encoding crustacean cardioactive peptide (CCAP) were isolated from several decapod (brachyuran and astacuran) crustaceans: the blue crab Callinectes sapidus , green shore crab Carcinus maenas...

... preparation caused an increase in bursting frequency in the FG, whereas application of 10 -6 mol l -1 eclosion hormone (EH) caused an instantaneous, though temporary, total inhibition of all FG rhythmic activity. Crustacean cardioactive peptide (CCAP), an important peptide believed to turn on ecdysis...

... by injecting sensitive animals with the neuropeptide ecdysis-triggering hormone (ETH). Exposure to ETH stimulates the release of eclosion hormone (EH) which, in turn, activates a set of neurons containing crustacean cardioactive peptide (CCAP) by elevating their levels of intracellular cyclic GMP. We...

...P. K. LOI; S. A. EMMAL; Y. PARK; N. J. TUBLITZ SUMMARY The crustacean cardioactive peptide (CCAP) gene was isolated from the tobacco hawkmoth Manduca sexta . The gene has an open reading frame of 125 amino acid residues containing a single, complete copy of CCAP. Analysis of the gene structure...

... showing distinct behavioural changes involved in the shedding of the head appendages, abdomen and pereiopods. Together with an enzyme immunoassay for crustacean cardioactive peptide (CCAP), the substaging has been used to demonstrate a large, rapid and reproducible peak in haemolymph CCAP levels...

...Stephen C. Gammie; James W. Truman ABSTRACT Three insect peptide hormones, eclosion hormone (EH), ecdysis-triggering hormone (ETH) and crustacean cardioactive peptide (CCAP), have been implicated in controlling ecdysis behavior in insects. This study examines the interactions between these three...

... as well as a release of EH within the central nervous system. This phasic signal then causes the tonic activation of a distributed network of peptidergic neurones that contain crustacean cardioactive peptide. The relationship of the latter cells to the subsequent maintenance of the ecdysis motor programme...
