Animal Nutrition, 2022 Cholesterol, as an indispensable nutrient, regulates molting and growth in crustacean. As crustaceans are unable to biosynthesize cholesterol de novo, it is central to understand how dietary cholesterol affects molting in crustaceans.

Steroid hormone ecdysone deficiency stimulates preparation for photoperiodic reproductive diapause
PLoS 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.

Ecdysone acts through cortex glia to regulate sleep in Drosophila
bioRxiv, 2022 Steroid hormones are attractive candidates for transmitting long-range signals to affect behavior. These lipid-soluble molecules derived from dietary cholesterol easily penetrate the brain and act through nuclear hormone receptors (NHRs) that function as

Regulation of ecdysone production in Drosophila by neuropeptides and peptide hormones
Open Biology, 2021 In both mammals and insects, steroid hormones play a major role in directing the animal's progression through developmental stages. To maximize fitness outcomes, steroid hormone production is regulated by the environmental conditions experienced by the ...

Transcriptional Activation of Ecdysone-Responsive Genes Requires H3K27 Acetylation at Enhancers
International Journal of Molecular Sciences, 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

Ecdysone regulates Drosophila wing disc size via a TORC1 dependent mechanism
Nature Communications, 2021 Most cells in a developing organ stop proliferating when the organ reaches a correct, final size. The underlying molecular mechanisms are not understood. We find that in Drosophila the hormone ecdysone controls wing disc size.

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.

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 ...
