Application

20-Hydroxyecdysone has been used:
  • in Leibovitz′s dissecting medium for culturing sorting zone and neuropil-associated glia and antennal lobes of Manduca sexta
  • in Schneider′s medium to reproduce ex-vivo imaginal disc eversion
  • as a supplement in Mcl8 medium for culturing Drosophila wing imaginal discs

Biochem/physiol Actions

20-Hydroxyecdysone is an ecdysteroid hormone that plays a key role in insect development, cell proliferaton, growth and apoptosis by controlling gene expression involved in molting and metamorphosis. It acts through a heterodimeric receptor comprising the ecdysone receptor and the ultraspiracle proteins (USP).

In 1974, Ashburner and colleagues postulated a model to explain the control of the puffing sequence on Drosophila polytene chromosomes initiated by the molting hormone 20-hydroxyecdysone. This model inspired a generation of molecular biologists to clone and characterize elements of

Insect metamorphosis proceeds in two modes: hemimetaboly, gradual change along the life cycle; and holometaboly, abrupt change from larvae to adult mediated by a pupal stage. Both are regulated by 20-hydroxyecdysone (20E), which promotes molts, and juvenile hormone (JH), which

Mature microRNAs (miRNAs) are processed from primary transcripts (pri-miRNAs), and their expression is controlled at transcriptional and post-transcriptional levels. However, how regulation at multiple levels achieves precise control remains elusive. Using published and new datasets, we profile a time course
