Invertebrate neuropeptide hormones
International Journal of Peptide and Protein Research, 1983The development of a long‐term research program on the neurosecretory hormones of arthropods is described. The purification and full characterization of the first invertebrate neurohormones, the red pigment‐concentrating hormone (RPCH) and the distal retinal pigment hormone (DRPH) demonstrated that they are peptides, an octapeptide and an ...

Ultraspiracle: An invertebrate nuclear receptor for juvenile hormones [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1997 Juvenile hormones (JH), a sesquiterpenoid group of ligands that regulate developmental transitions in insects, bind to the nuclear receptor ultraspiracle (USP). In fluorescence-based binding assays, USP protein binds JH III and JH III acid with specificity, adopting for each ligand a different final conformational state.

Invertebrate Hormones and Tumors
1974Hereditary, melanotic tumors in Drosophila have attracted the attention of research workers since the report of Bridges (1916) that a gene, 1(1)7, causes melanotic tumors associated with the presence of clusters of larval cells that become pigmented. Stark (1935) viewed these tumors as possibly analogous to lymphosarcoma in vertebrates.

Experientia, 1979
Antibodies against hyperglycemic hormone (CHH) of Carcinus were raised in rabbits by injection of extract from sinus glands which contain high concentrations of CHH. The antiserum neutralizes the biological activity of CHH and binds 125-J-CHH. A RIA for CHH was established and was used to measure the hormone content of sinus glands.

Hormonal control of invertebrate behavior
Hormones and Behavior, 1978Abstract Invertebrates show a wide variety of behaviors that are influenced by hormones. In insects the involvement of hormones at a particular life stage is directly correlated with the complexity of the behavioral repertoire at that stage. In larval stages, the steroid hormone, ecdysone, when present with juvenile hormone, apparently causes the ...

Chromatographic Detection and Immunoassay of Invertebrate Hormones
1974Bioassays of invertebrate hormones continue to serve a very useful purpose, but other approaches to detection that could become more specific and sensitive have been explored and are beginning to yield encouraging results. Principal alternatives that have been used both for isolation and identification of these hormones and analogs are radioimmunoassay
