Phytoecdysteroids in the Genus (Polypodiaceae) of French Polynesia

Natural Product Communications, 2007
A chemical survey of the six species of Microsorum in French Polynesia has been performed to determine and quantify the phytoecdysteroids. The content and composition of these compounds in the fronds of each of the six species were established.

20-Hydroxyecdysone (20E) Primary Response Gene E75 Isoforms Mediate Steroidogenesis Autoregulation and Regulate Developmental Timing in Bombyx*

Journal of Biological Chemistry, 2016
The temporal control mechanisms that precisely control animal development remain largely elusive. The timing of major developmental transitions in insects, including molting and metamorphosis, is coordinated by the steroid hormone 20-hydroxyecdysone (20E)

miR-34-5p mediates 20E-induced autophagy in the fat body of Bombyx mori by targeting Atg1

BMC Genomics
Background 20-Hydroxyecdysone (20E) is an important hormone that regulates insect development and metamorphosis. The fat body of insects plays a crucial role in nutrient storage and energy metabolism and is considered the exchange center for regulating ...

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

Regeneration ofSarcophagaImaginal Discsin Vitro:Implication of 20-Hydroxyecdysone

Developmental Biology, 1997
When the 3/4 sectors of leg imaginal discs of Sarcophaga were cultured in vitro in the presence of 2.5 x 10(-8) M 20-hydroxyecdysone, wound healing and restoration of their morphology occurred. This concentration of ecdysone was critical for wound healing and was 40 times lower than that necessary for inducing differentiation of imaginal discs in vitro.

Effect of 20-Hydroxyecdysone, a Phytoecdysteroid, on Development, Digestive, and Detoxification Enzyme Activities of Tribolium castaneum (Coleoptera: Tenebrionidae)

Journal of Insect Science, 2019
Plants present a delimited reservoir of biologically active compounds. Many plants synthesize several compounds of secondary metabolism, such as alkaloids, terpenoids, phenolics, steroids, etc. Such compounds are generally thought to be involved in plant–
