ecdysone

noun ɛkˈdʌɪsəʊnˈɛkdɪsəʊnˈekdəˌsōn
mass nounBiochemistry
  • A steroid hormone that controls moulting in insects and other arthropods.

    Example sentencesExamples
    • Two hormones in particular drive these fundamental processes: ecdysone and juvenile hormone.
    • Larval molting in Drosophila, as in other insects, is initiated by the coordinated release of the steroid hormone ecdysone, in response to neural signals, at precise stages during development.
    • A pulse of the steroid hormone ecdysone at the onset of metamorphosis triggers the rapid transformation of a flat leg imaginal disc into an immature adult leg, largely through coordinated changes in cell shape.
    • Consequently, both the onset and the termination of disc growth are determined by the joint action of ecdysone and juvenile hormone.
    • This checkpoint may be controlled by signaling through the steroid hormone ecdysone.
