Nature Communications, 2017 InDrosophila, ecdysone-regulated genes are bound by a heterodimer of ecdysone receptor (EcR) and Ultraspiracle. Here, the authors provide evidence of a non-canonical complex containing EcR and the nucleosome remodeller dMi-2 that limits transcription of ...

Memorias do Instituto Oswaldo Cruz, 1988 Third instar larvae of Stomoxys calcitrans (L.) were treated with precocene II, ecdysone and juvenile hormone. The larvae were allowed to develop until pupation and when it occurred, determination of glycogen levels was assayed.

Coordinated regulation of niche and stem cell precursors by hormonal signaling. [PDF]
PLoS Biology, 2011 Stem cells and their niches constitute units that act cooperatively to achieve adult body homeostasis. How such units form and whether stem cell and niche precursors might be coordinated already during organogenesis are unknown.

Transcriptional Activation of Ecdysone-Responsive Genes Requires H3K27 Acetylation at Enhancers
, 2022 The steroid hormone ecdysone regulates insect development via its nuclear receptor (the EcR protein), which functions as a ligand-dependent transcription factor. The EcR regulates target gene expression by binding to ecdysone response elements (EcREs) in

The ecdysone receptor puzzle [PDF]
, 1999 : The present article reviews some recent findings on the functional ecdysone † receptor which is a heterodimer of two proteins: ecdysone receptor (EcR) and Ultraspiracle (USP).

Deep sequencing of the prothoracic gland transcriptome reveals new players in insect ecdysteroidogenesis. [PDF]
PLoS ONE, 2017 Ecdysteroids are steroid hormones that induce molting and determine developmental timing in arthropods. In insect larva, the prothoracic gland (PG) is a major organ for ecdysone synthesis and release.

Environmental Toxicology and Chemistry, EarlyView.Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...

Interactions of ultraspiracle with ecdysone receptor in the transduction of ecdysone‐ and juvenile hormone‐signaling [PDF]
The FEBS Journal, 2005 Analyses of integration of two‐hormone signaling through the vertebrate nuclear hormone receptors, for which the retinoid X receptor is one partner, have generated a number of mechanistic models, including those described as ‘subordination’ models wherein ligand‐activation of one partner is subordinate to the liganded state of the other partner ...

Pest Management Science, EarlyView.Extended bioassays revealed that azadirachtin and spirotetramat show strong delayed effects against Phthorimaea absoluta, underestimated by the standard Insecticide Resistance Action Committee (IRAC) method 022 protocol. Incorporating long‐term exposures is essential to accurately assess slow‐acting insecticides and improve resistance management ...
