Neuropepride Regulators of Insect Corpora Allata

American Zoologist, 1993
SYNOPSIS. Neuropeptides of the insect brain that regulate juvenile hormone synthesis by the corpora allata include allatotropins, stimulatory modulators, and allatostatins, inhibitory modulators. A radiochemical assay for juvenile hormone synthesis by corpora allata in vitro was utilized in the high pressure liquid chromatographic isolation of brain ...

Regulation of larval corpora allata in Galleria mellonella

Nature, 1974
IN insects metamorphosis occurs when the corpora allata stop secreting juvenile hormone, but it is not known how the production of juvenile hormone is regulated. Wigglesworth1 first indicated that the nervous connections from the brain to the corpora allata provide a mechanism for control; this control could be nervous or neurohormonal.

In vitro growth of corpora allata fromDiploptera punctata

In Vitro Cellular & Developmental Biology - Animal, 1995
An in vitro organ culture system was established to support growth of corpora allata from the cockroach Diploptera punctata. During a 1-wk incubation in L-15B medium supplemented with 10% fetal bovine serum (FBS) and 10% cockroach hemolymph, adult male corpora allata exhibited a cycle of de novo DNA synthesis followed by cell division.

Prenyltransferase of larval and adult M. sexta corpora allata

Insect Biochemistry and Molecular Biology, 2007
Prenyltransferase activity derived from the corpora allata (CA) of the lepidopteran insect, Manduca sexta, has been characterized. The coupling of allylic substrates DMAPP and GPP with the non-allylic substrate IPP was evaluated using CA homogenates of both the larval and adult stages of development.
