Does corazonin signal nutritional stress in insects?
2009, Insect Biochemistry and Molecular BiologyCitation Excerpt :It is interesting to see that in crustaceans both GnRH homologs, i.e. RPCH and corazonin, effect tegumentary chromatophores. The half life of corazonin in the hemolymph has been reported to be about 20 min (Vandersmissen et al., 2006), a value close to the physiological half life of the hyperglycemic hormones of the American cockroach, which have a similar structure (Veenstra, 1989b). Such a short half life makes it virtually impossible for the injected hormone to persist for several days, as needed for two of the bioassays used for corazonin, the effects on phase transition in locusts, and spinning in silk worm.
Drosophila Neuropeptide Signaling
2003, Advances in GeneticsCitation Excerpt :Neuropeptide signaling is terminated by a combination of mechanisms that include receptor desensitization or internalization, peptide diffusion, and enzymatic degradation by specific peptidases (reviewed by Grady et al., 1997). The half-lives of a few insect neuropeptides have been studied and found not to be significantly different from those of vertebrates (Reynolds et al., 1979; Quistad et al., 1984; Veenstra, 1989b). In this section we review work on the identification of peptidases that have been implicated in terminating insect peptide signaling (Table 1.5).
