Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance In vertebrates, steroid hormones regulate developmental transition from juveniles to adults. Insect steroid hormone, 20-hydroxyecdysone (20E), coordinates with juvenile hormone (JH) to regulate metamorphosis; however, the precise cross-talk ...

Halloween genes in panarthropods and the evolution of the early moulting pathway in Ecdysozoa [PDF]
Royal Society Open Science, 2018 Moulting is a characteristic feature of Ecdysozoa—the clade of moulting animals that includes the hyperdiverse arthropods and less speciose groups, such as onychophorans, tardigrades and nematodes.

New insights on the effects of spinosad on the development of Helicoverpa armigera
Ecotoxicology and Environmental Safety, 2021 Helicoverpa armigera (cotton bollworm) is one of the most destructive pests worldwide. Due to resistance to Bacillus thuringiensis and conventional insecticides, an effective management strategy to control this pest is urgently needed.

New Cytotoxic Steroid from Stachyurus imalaicus var. himalaicus
Molecules, 2007 A phytochemical study of the ethanolic extract of Stachyurus imalaicus var. himalaicus was undertaken and as a result a new polyoxygenated steroid, named stachsterol ((20S)-20, 25-dihydroxy-4-cholesten-3-one, 1) and three known ecdysteroids, 20 ...
