dissertationn the fruit fly Drosophila melanogaster, a pulse of the steroid hormone ecdysone triggers metamorphosis. Ecdysone activates a genetic regulatory hierarchy that can be visualized as a reproducible pattern of puffs in the polytene chromosomes ...

Ecdysone concentration by month for infected and uninfected crabs.
Monthly boxplots of pooled ecdysone concentrations for uninfected and infected crabs are shown. The p-values listed corresponds to the t-test of ecdysone concentration between infected and uninfected crabs for each month.

Examining Relationships Between Nitric Oxide, Iron and Ecdysone Biosynthesis
Pulses of ecdysone, a steroid hormone, play an integral role during insect development however, how these ecdysone pulses are regulated has been relatively unexplored.

Ecdysone metabolism in the tick Ornithodoros moubata (Argasidae, Ixodoidea)
The metabolism of injected [3H]ecdysone was studied in final-instar nymphs of Ornithodoros moubata (Murr.) at different stages of the moult cycle in the laboratory in Switzerland.

The ecdysone signaling pathway plays a major role in various developmental transitions in insects. Recent advances in the understanding of ecdysone action have relied to a large extent on the application of molecular genetic tools in Drosophila. Here, we

Bioassay of Human Tissues for Ecdysone.
Brain(1), corpus allatum(2), and prothor-acic gland(3,4,5) of insects(6,7) have yielded respective active hormones on bioassay. Recently Kobayashi and co-workers(8) found cholesterol to be an active component in the brain of Bombyx. Schmialek(9) isolated farnesol and, with Wigglesworth(10), showed it to act in a manner similar to juvenile hormone ...

molting defective is required for ecdysone biosynthesis
20-hydroxyecdysone was discovered as the major biologically active insect steroid hormone half a century ago, yet much remains to be learned about its biosynthesis and its activities.
