... and Drosophila melanogaster , the larval size at which metamorphosis is initiated largely determines adult size, and metamorphosis is initiated when larvae attain a critical mass. We hypothesized that oxygen effects on final size might be mediated by oxygen effects on the critical weight and the ecdysone titers...

... suggests that elevated ecdysone may facilitate onset of diapause in A. socius . Upregulation seen for the transcription factors Reptin and TFDp2 may serve to depress transcription and cell cycle progression. Cathpesin B-like protease, ACLY and MSP are three downregulated genes associated with yolk...

Palli; Marc Tatar; Neal Silverman SUMMARY Juvenile hormone (JH) and 20-hydroxy-ecdysone (20E) are highly versatile hormones, coordinating development, growth, reproduction...

... Caenorhabditis elegans ; domain IV was replaced by a unique `T domain' sequence. It was expressed in most tissues,except eyestalk ganglia and Y-organ. The effects of elevated ecdysteroid,induced by eyestalk ablation, on calpain and ecdysone receptor (Gl-EcR) mRNA levels in skeletal muscles were quantified...

...R. D. Watson; T. K. Williams; W. E. Bollenbacher ABSTRACT A recently isolated haemolymph protein appears to be an important regulator of ecdysone biosynthesis by prothoracic glands in Manduca sexta . Using a dose-response titration protocol, the haemolymph titre of this stimulatory factor...

...Wendy A. Smith; M. F. Bowen; Walter E. Bollenbacher; Lawrence I. Gilbert ABSTRACT Prothoracic glands from diapausing pupae of the tobacco hornworm, Manduca sexta , synthesize markedly less ecdysone in vitro in response to prothoracicotropic hormone (PTTH) than do glands from non-diapausing pupae...

... of the steroid moulting hormone is thought to be responsible for the diapause state and it is apparently a consequence of the failure of the diapausing pupal prothoracic glands (PG) to synthesize ecdysone at an increased rate. In Manduca , this apparent failure of PG activation during diapause may be in response...
