Juvenile fibromatosis: hormonal receptors

International Journal of Pediatric Otorhinolaryngology, 1993
Aggressive juvenile fibromatosis, though allegedly a benign process, is as frustrating to manage as it is perplexing to comprehend. The treatment is primarily surgical, with chemotherapy and radiation therapy recently finding support as adjuncts in selected circumstances.

Regulation of juvenile hormone esterase gene transcription by juvenile hormone

Developmental Genetics, 1994
AbstractJuvenile hormone (JH) is a major hormone regulating insect development. We have obtained a cDNA and a genomic clone for juvenile hormone esterase (JHE), the enzyme that is involved in the degradation of juvenile hormone and which is critical for insect development. Analysis of the regulation of JHE during the final larval stadium in the cabbage

Juvenil- and Steroid-Hormone

2013
Mevalonsaure ist der Vorlaufer, aus denen in allen Tierarten Squalen und Cholesterin oder davon abgewandte Strukturen gebildet werden. Das sind einerseits bei den Wirbeltieren die Steroidhormone und Vitamin D3, bei Nichtwirbeltieren und auch Pflanzen Cholesterolderivate, und bei Ecdysocoa noch das Juvenilhormon, dessen Bildung nicht uber Squalen ...

Juvenile hormone esterase is a biochemical anti-juvenile hormone agent

Insect Biochemistry, 1990
Juvenile hormone esterase, purified by affinity chromatography from the larval hemolymph of Manduca sexta in the fifth stadium, was injected into larvae of the same species in the earlier stadia resulting in a blackening of the cuticle following ecdysis to the next larval stadium.

Peptides with Juvenile Hormone Activity

Science, 1970
Peptide derivatives of juvenile hormone analogs which show substantial hormonal activity for certain insects were prepared. The most active compound, L-isoleucyl-L-alanyl- p -aminobenzoic acid ethyl ester, was up to twice as active as juvabione.

Hydroxy Juvenile Hormones: New Putative Juvenile Hormones Biosynthesized by Locust Corpora Allatain Vitro

Biochemical and Biophysical Research Communications, 1997
The in vitro production of sesquiterpenoids was investigated by using corpora allata (CA) of the African locust Locusta migratoria migratorioides. Labeled products from unstimulated biosynthesis were extracted, purified by normal phase HPLC, and derivatized to determine the functional groups present.
