(Zoology) a hormone secreted by the prothoracic gland of insects that controls ecdysis and stimulates metamorphosis [C20: from Germanecdyson,from Greekekdusis;see ecdysis] Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 1998, 2000,...
20-hydroxyecdysone (20E; also known as ecdysterone), an ecdysone analogue, is secreted by the prothoracic glands of lepidopterans (Subramanian and Shankarganesh, 2016) and is associated with various male and female reproductive processes. A study in Drosophila revealed that the ecdysone receptor is...
Ecdysones are hormones that regulate molting and metamorphosis in insects and are secreted by the living prothoracic gland (Karlson 1963). Diapause is associated with a deficiency of ecdysone, and by the administration of ecdysone, is terminated immediately by resumption of normal development. Such...
It is the target organ of prothoracotropic hormone (PTTH) secreted by the neurosecretory cells of the brain. Some investigators have shown that the prothoracic gland is the site王宗舜陈娥英伊淑霞魏定义郭郛殷之铭科学通报(英文版)王宗舜,陈娥英,伊淑霞,魏定义,郭郛,殷之铭.In vitro SYNTHESIS OF...
E93 encodes a transcription factor that is specifically induced by the prepupal pulse of ecdysone, supporting a model proposed by earlier work that it specifies the onset of adult development. Although a number of studies have addressed these functions for E93, little is known about its roles in...
Ultimately we will need to examine PTTH null mutants to prove that PTTH, and not some other factor, is the tropic signal secreted from the PG neurons. However, the recent finding that PTTH signals through the Drosophila receptor tyrosine kinase (RTK) Torso is certainly consistent with the ...
Ecdysone is a steroid hormone secreted by prothoracic gland that, in its active form, stimulates metamorphosis and regulates molting in insects. In the tobacco hornworm, Manduca sexta, these hormones control metamorphosis, especially processes of muscle degeneration and programmed neuron death (Weeks ...
