LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus
Insect Science, EarlyView.The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum
Insect Science, EarlyView.RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Origin and diversification of steroids: Co-evolution of enzymes and nuclear receptors [PDF]
, 2010 Recent sequencing of amphioxus and sea urchin genomes has provided important data for understanding the origins of enzymes that synthesize adrenal and sex steroids and the receptors that mediate physiological response to these vertebrate steroids ...

Frontiers in Physiology, 2017 Ovarian development plays an important role in the life history of insects and is crucial for control of the insect population. The metamorphosis of an insect is precisely regulated by the interaction of the juvenile hormone and ecdysone.

Transcriptional control of steroid biosynthesis genes in the Drosophila prothoracic gland by ventral veins lacking and knirps. [PDF]
PLoS Genetics, 2014 Specialized endocrine cells produce and release steroid hormones that govern development, metabolism and reproduction. In order to synthesize steroids, all the genes in the biosynthetic pathway must be coordinately turned on in steroidogenic cells.

Prioritising research on endocrine disruption in the marine environment: a global perspective
Biological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

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.

Bicistronic Expression of Ecdysone-Inducible Receptors in Mammalian Cells
BioTechniques, 2001 The recent emergence of inducible expression systems for mammalian cells has greatly facilitated the in vivo analysis of gene function. The ecdysone-inducible expression system is particularly attractive because of (i) extremely low basal expression and ...

Epitranscriptomics as a Candidate Universal Modulator of Dormancy Transitions
Ecology and Evolution, Volume 16, Issue 2, February 2026.Dormancy is presented as a conserved, reversible survival program in which epitranscriptomic RNA modifications are proposed to provide a rapid, energy‐efficient layer that establishes, maintains, and terminates the state by modulating mRNA stability, translation, and localization.
