Developmental regulation of ecdysone
receptor (EcR) and EcR-controlled gene expression during pharate-adult development of honeybees (Apis mellifera).
2011) showed that in the cladoceran crustacean species Daphnia magna, RXR is activated by TBT and elicits toxicity by interfering with the ecdysone
The roles of juvenile hormone, ecdysone
and the ovary in the control of Drosophila vitellogenesis.
Our current working theory is based upon an inference that PCP may act as an antagonist on ecdysone
receptors related to growth and development.
Female lobsters were used in this study to reduce the variability that would have been introduced by analyzing lobsters of both genders, because severe cases of ESD are relatively common in ovigerous females, and because abnormal molting and ecdysone
levels have been reported in females with signs of ESD (Laufer et al.
remota has led to the identification of various compounds like ajugarin I, II an III along with ajugasterone C, ajugalactone, cyasterone, [beta] ecdysone
and ergosterol 5, 8-peroxide.
Fifth larval instar Manduca sexta midgut mitochondria catalyze ecdysone
conversion to the active hormone, 20-hydroxyecdysone, via ecdysone
On the basis of the mode of action, IGRs are grouped into three categories: juvenile hormones (JHs) and their analogs (JHAs), also called juvenoids; ecdysone
agonists (EA); and chitin synthesis inhibitors (CSIs) or molt inhibitors (MIs) .
This process is controlled by ecdysone
, an insect hormone that regulates gene activity during metamorphosis (development), reproduction and moulting.
The rate of synthesis and secretion of ecdysone
by the Y-organ is negatively regulated by the X-organ sinus gland complex.
The exogenous application of ecdysone
or their allied forms generally upsets the hormonal titre in the body and results in moulting disorder (Giesultwiz et al.
Drosophila ultraspiracle modulates ecdysone
receptor function via heterodimer formation.
