Drosophila tissues with different metamorphic responses to ecdysone express different ecdysone receptor isoforms

open access: yesCell, 1993
In D. melanogaster a pulse of the steroid hormone ecdysone triggers the larval-to-adult metamorphosis, a complex process in which this hormone induces imaginal tissues to generate adult structures and larval tissues to degenerate. We show that the EcR gene encodes three ecdysone receptor isoforms (EcR-A, EcR-B1, and EcR-B2) that have common DNA- and ...

Steroid receptor coactivator TAIMAN is a new modulator of insect circadian clock.

open access: yesPLoS Genetics, 2023
TAIMAN (TAI), the only insect ortholog of mammalian Steroid Receptor Coactivators (SRCs), is a critical modulator of ecdysone and juvenile hormone (JH) signaling pathways, which govern insect development and reproduction.

Steroid Control of Longevity in Drosophila melanogaster [PDF]

open access: yes, 2003
Ecdysone, the major steroid hormone of Drosophila melanogaster, is known for its role in development and reproduction. Flies that are heterozygous for mutations of the ecdysone receptor exhibit increases in life-span and resistance to various stresses ...

Steroid hormone ecdysone deficiency stimulates preparation for photoperiodic reproductive diapause.

open access: yesPLoS Genetics, 2021
Diapause, a programmed developmental arrest primarily induced by seasonal environmental changes, is very common in the animal kingdom, and found in vertebrates and invertebrates alike.

Ecdysteroids: 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

Mechanisms regulating nutrition-dependent developmental plasticity through organ-specific effects in insects [PDF]

open access: yes, 2013
Nutrition, via the insulin/insulin-like growth factor (IIS)/Target of Rapamycin (TOR) signaling pathway, can provide a strong molding force for determining animal size and shape.

Diverse Hormone Response Networks in 41 Independent Drosophila Cell Lines

open access: yesG3: Genes, Genomes, Genetics, 2016
Steroid hormones induce cascades of gene activation and repression with transformative effects on cell fate . Steroid transduction plays a major role in the development and physiology of nearly all metazoan species, and in the progression of the most ...
