Action of ecdysterone on the moulting of amphipod females: Gammarus pulex (L.) and G.fossarum Koch. Early results. [Translation from: Crustaceana 28, 86-88, 1975.] [PDF]

open access: yes, 1975
In studying sexual attraction in gammarids of the group pulex, it has seemed necessary to dissociate the processes of moulting and ovogenesis in order to recognize their respective effects on this phenomenon.

Genes for Drosophila small heat shock proteins are regulated differently by ecdysterone

open access: yes, 1991
Genes for small heat shock proteins (hsp27 to hsp22) are activated in late third-instar larvae of Drosophila melanogaster in the absence of heat stress.

A novel class of anabolic agents? [PDF]

open access: yes, 2015
Increasing numbers of dietary supplements with ecdysteroids are marketed as “natural anabolic agents”. Results of recent studies suggested that their anabolic effect is mediated by estrogen receptor (ER) binding. Within this study the anabolic potency of

Identification, purification and functional analysis of ecdysterone receptor from Drosophila melanogaster

open access: yes, 1990
The ecdysterone receptor regulates the expression of an array of genes during Drosophila puparium formation, and therefore, plays a key role in development.

Synthesis of Low Molecular Weight Heat Shock Peptides Stimulated by Ecdysterone In a Cultured Drosophila Cell Line. [PDF]

open access: yes, 1982
Treatment of Schneider\u27s line 3 Drosophila cells with the steroid hormone ecdysterone rapidly stimulated the synthesis and accumulation of the polypeptide previously designated p7 [Berger, E. M., Ireland, R. C. & Wyss, C. (1980) Somatic Cell Genet. 6,

Haemolymph calcium in Helix pomatia: effects of EGTA, ganglion extracts, ecdysterone, cyclic amp and ionophore A23187

open access: yes, 1977
1. After snails (Helix pomatia) have been infused with Na4EGTA, levels of unchelated Ca return to normal in about 0.5 hr and then rise higher. 2.

EFFECTS OF ECDYSTERONE ON THE DEPOSITION OF COCKROACH CUTICLEIN VITRO

open access: yesThe Biological Bulletin, 1972
Quantitative studies were made of the stimulation of cuticular deposition in cockroach leg regenerates in vitro by the molting hormone ecdysterone. Preliminary experiments showed that the hormone remained active and that the tissues remained sensitive in vitro for as long as 30 days.
