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

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

Three distinct classes of nuclear receptors, EcR, E75, and HR3, are key regulators in the ecdysone-inducible gene activation cascade in insects. The transcription of these genes is induced by ecdysone (20E) differently, although the detailed mechanisms underlying their responses to

Insect metamorphosis is one of the most fascinating biological processes in the animal kingdom. The dramatic transition from an immature juvenile to a reproductive adult is under the control of the steroid hormone ecdysone, also known as the insect molting

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

In Drosophila, growth takes place during the larval stages until the formation of the pupa. Starvation delays pupariation to allow prolonged feeding, ensuring that the animal reaches an appropriate size to form a fertile adult. Pupariation is induced by a
