Ecdysone and 20 hydroxyecdysone: new hormones for the human parasite Schistosoma mansoni

, 1983
The insect moulting hormones, ecdysone and 20 hydroxyecdysone, were detected by the combined use of radioimmunoassay and high performance liquid chromatography in the human parasite Schistosoma mansoni. On day 11 after infection only the ecdysone form is

SRP/dGATAb modulates the ecdysone response bidirectionally via locus-specific regulatory landscape

Epigenetics & Chromatin
Background Steroid hormones drive the transcription of developmental genes by activating distinct sets of enhancers across tissues and developmental contexts, but the mechanisms that target specific enhancers remain incompletely understood, even in model

Disrupting shadow in the prothoracic gland induced larval development arrest in the fall armyworm Spodoptera frugiperda

Frontiers in Physiology
IntroductionThe juvenile hormone (JH) and 20-hydroxyecdysone (20E) are the central regulating hormones of insect development. The timing of their secretion usually leads to developmental transitions.MethodsThe developmental transitions were evaluated via
