Ecdysone coordinates plastic growth with robust pattern in the developing wing

eLife, 2022
Animals develop in unpredictable, variable environments. In response to environmental change, some aspects of development adjust to generate plastic phenotypes.

Azadirachtin disrupts ecdysone signaling and alters sand fly immunity [PDF]

Parasites & Vectors
Background Leishmaniasis is a group of neglected vector-borne diseases transmitted by phlebotomine sand flies. Leishmania parasites must overcome various defenses in the sand fly midgut, including the insects’s immune response.

Bicistronic Expression of Ecdysone-Inducible Receptors in Mammalian Cells [PDF]

BioTechniques, 2001
The recent emergence of inducible expression systems for mammalian cells has greatly facilitated the in vivo analysis of gene function. The ecdysone-inducible expression system is particularly attractive because of (i) extremely low basal expression and ...

Larval diapause termination in the bamboo borer, Omphisa fuscidentalis. [PDF]

PLoS ONE, 2017
In insects, juvenile hormone (JH) and 20-hydroxyecdysone (20E) regulate larval growth and molting. However, little is known about how this cooperative control is terminating larval diapause especially in the bamboo borer, Omphisa fuscidentalis.

Spider Hemocyanin Binds Ecdysone and 20-OH-Ecdysone [PDF]

Journal of Biological Chemistry, 1999
Fluorescence quenching studies and binding experiments with [(3)H]ecdysone reveal that the respiratory protein, hemocyanin, of the tarantula Eurypelma californicum binds ecdysone. The binding constant for ecdysone ranges between 0.5 and 5 mM, indicating a low affinity binding.

Network pharmacology combined with molecular docking to explore the anti-osteoporosis mechanisms of β-ecdysone derived from medicinal plants

Open Chemistry, 2022
β-Ecdysone is a phytosteroid derived from multifarious medicinal plants, such as Achyranthes root (Achyranthes bidentata) and Tinospora cordifolia, possessing the potential anti-osteoporosis effect.

Ecdysone Quantification from Whole Body Samples of Drosophila melanogaster Larvae

Bio-Protocol, 2021
Steroid hormones strictly control the timing of sexual maturation and final body size both in vertebrates and invertebrates. In insects, the steroid hormone ecdysone controls the timing of the molts between larval instars as well as the transition to ...

Co-option of immune effectors by the hormonal signalling system triggering metamorphosis in Drosophila melanogaster.

PLoS Genetics, 2021
Insect metamorphosis is triggered by the production, secretion and degradation of 20-hydroxyecdysone (ecdysone). In addition to its role in developmental regulation, increasing evidence suggests that ecdysone is involved in innate immunity processes ...
