Allgemeine Beschreibung

α-Ecdysone is a phytoecdysteroid, synthesized from cholesterol, and one of the major insect molting hormones. Ecdysone is secreted by the ecdysial glands present in insects.

Anwendung

α-Ecdysone has been used:
  • to study its effects on Drosophila melanogaster′s sexual maturation
  • to study its effects on specification of neurons in Drosphila male-specific neurite
  • as a standard to evaluate the ecdysteroid levels by liquid chromatography-mass spectrometry (LC-MS/MS)

Biochem./physiol. Wirkung

Ecdysone exerts its effects via the ecdysone receptor and regulates larval molting, reproduction, and metamorphosis in insects.

Steroid hormones act as important developmental switches, and their nuclear receptors regulate many genes. However, few hormone-dependent enhancers have been characterized, and important aspects of their sequence architecture, cell-type-specific activating and repressing functions, or the regulatory roles of their chromatin

The concentration changes of endogenous ecdysteroids are closely related to the regulation of insect growth and development. Although they are frequently measured by immunoassays with anti-steroid antibodies, the separate estimations of the individual concentrations of ecdysone and other ecdysteroids with

Steroid hormones trigger the onset of sexual maturation in animals by initiating genetic response programs that are determined by steroid pulse frequency, amplitude and duration. Although steroid pulses coordinate growth and timing of maturation during development, the mechanisms generating these
