Fungal Ecdysteroid-22-oxidase, a New Tool for Manipulating Ecdysteroid Signaling and Insect Development [PDF]

, 2012
Steroid hormones ecdysteroids regulate varieties of developmental processes in insects. Although the ecdysteroid titer can be increased experimentally with ease, its artificial reduction, although desirable, is very difficult to achieve.

Differential Requirement for Translation Initiation Factor Pathways during Ecdysone-Dependent Neuronal Remodeling in Drosophila.

Cell Reports, 2018
Dendrite pruning of Drosophila sensory neurons during metamorphosis is induced by the steroid hormone ecdysone through a transcriptional program. In addition, ecdysone activates the eukaryotic initiation factor 4E-binding protein (4E-BP) to inhibit cap ...

Small Molecule‐Based Conditional Gene Regulation: Advances and Applications

Chemistry–Methods, Volume 6, Issue 4, April 2026.
The precise, temporal, and reversible control of gene expression using small molecule ligands is crucial for understanding complex cellular functions and is rapidly advancing the field of synthetic biology. Small molecule‐mediated conditional gene regulation has widespread applications, including bio‐manufacturing, cellular reprogramming, gene therapy,

Expressions of the cytochrome P450 monooxygenase gene Cyp4g1 and its homolog in the prothoracic glands of the fruit fly Drosophila melanogaster (Diptera: Drosophilidae) and the silkworm Bombyx mori (Lepidoptera: Bombycidae) [PDF]

, 2011
Here we describe the expression profiles of the cytochrome P450 monooxygenase gene Cyp4g1 in the fruit fly, Drosophila melanogaster Meigen, and its homolog in the silkworm, Bombyx mori L.

Metamorphosis and lncRNAs: A Close Relationship

genesis, Volume 64, Issue 2, April 2026.
ABSTRACT The classical definition of metamorphosis is a post‐embryonic transformation, such as from a tadpole to a froglet. However, recent studies suggest this process occurs to some degree in all vertebrates, as the underlying endocrine and molecular pathways are highly conserved. With the advent of high‐throughput sequencing, transcriptomic data for

Nutrient-Dependent Endocycling in Steroidogenic Tissue Dictates Timing of Metamorphosis in Drosophila melanogaster [PDF]

, 2017
Many animals have an intrinsic growth checkpoint during juvenile development, after which an irreversible decision is made to upregulate steroidogenesis, triggering the metamorphic juvenile-to-adult transition.

Ecdysone Oxidase: Reaction and Specificity [PDF]

European Journal of Biochemistry, 1978
Ecdysone oxidase oxidizes 3‐hydroxysteroids of the ecdysteroid type irreversibly to 3‐dehydro derivatives. The hydrogen of the steroid is transferred by the enzyme to oxygen which is reduced to hydrogen peroxide. Ecdysone oxidase is relatively specific for ecdysone and ecdysterone. Apparent Michaelis constants for these two physiological substrates are

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.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, Volume 33, Issue 2, Page 640-664, April 2026.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

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.
