Ecdysone oxidase and 3-dehydroecdysone-3β-reductase contribute to the synthesis of ecdysone during early embryonic development of the silkworm

International Journal on Biological Sciences, 2018
Maternal ecdysteroids regulate a variety of cellular processes during early embryonic development of insects, yet little is known about the genes involved in the biosynthesis of these hormones.

Morin hydrate reduces survival and fertility, delays development and weakens lipid reserves in Aedes aegypti

Medical and Veterinary Entomology, EarlyView.
Morin hydrate promoted mortality and reduced the rate of pupation and egg laying in Aedes aegypti larvae that survive treatment. Morin hydrate reduces the levels of triacylglycerol, the main lipid reserve in A. aegypti larvae. The expression of proteins involved in lipogenesis and lipolysis was downregulated and upregulated, respectively, in larvae ...

Annotation of Tribolium nuclear receptors reveals an evolutionary overacceleration of a network controlling the ecdysone cascade [PDF]

Insect Biochemistry and Molecular Biology 4, 38 (2008) 416-429, 2008
The Tribolium genome contains 21 nuclear receptors, representing all of the six known subfamilies. When compared to other species, this first complete set for a Coleoptera reveals a strong conservation of the number and identity of nuclear receptors in holometabolous insects.

Serum metabolic and microbial profiling yields insights into promoting effect of tryptophan‐related metabolites for health longevity in centenarians

iMeta, Volume 4, Issue 3, June 2025.
Schematic representation of the design. Tryptophan metabolism is enriched in serum metabolites and gut microbiota of centenarians, potentially contributing to healthy longevity. A key tryptophan metabolite 5‐methoxyindoleacetic acid (5‐MIAA) is linked to the Christensenellaceae R‐7 group and exhibits effects of delaying cell senescence, promoting ...

New reporter gene assays for detecting natural and synthetic molting hormone agonists using yeasts expressing ecdysone receptors of various insects

FEBS Open Bio, 2017
Synthetic nonsteroidal ecdysone agonists, a class of insect growth regulators (IGRs), target the ecdysone receptor (EcR), which forms a heterodimer with ultraspiracle (USP) to transactivate ecdysone response genes.

Unexpected soundscape response to insecticide application in oak forests

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract Rachel Carson's warning of a silent spring directed attention to unwanted side effects of pesticide application. Though her work led to policies restricting insecticide use, various insecticides currently in use affect nontarget organisms and may contribute to population declines.

Neuropeptide Ecdysis‐Triggering Hormone and Its Receptor Mediate the Fecundity Improvement of ‘Candidatus Liberibacter Asiaticus’‐Infected Diaphorina citri Females and CLas Proliferation

Advanced Science, Volume 12, Issue 18, May 15, 2025.
In CLas‐infected D. citri, CLas lowers 20E levels initially, relieving the suppression of ETH release. The subsequent increase in ETH levels upregulates its receptor DcETHR and activates the JH signaling pathway. The signaling cascade of 20E‐ETH/ETHR‐JH along with miR‐210, targeting DcETHR, boost female fecundity in CLas+ D.
