Our results indicate that levels of ecdysone
were increased in the hemolymph of shell-diseased lobsters, with a medium level of expression of the disease to 89 [+ or -] 32 ng/mL (n = 76), whereas unaffected, presumably healthy ones had 57 [+ or -] 16 ng/mL (n = 210).
Programmed cell death in the Drosophila CNS is ecdysone
-regulated and coupled with a specific ecdysone
binding antagonistically to an ecdysone
receptor) rather than a constructive interaction (i.
Our results are consistent with former studies showing that the molting and pupation of larvae were blocked by virus infection via controlling host insect ecdysone
levels (O'Reilly & Miller 1989; Liu et al.

Other investigators have shown interplay between MF and ecdysone

The identified compounds belonged to three structural types: ecdysone

Molting in decapod crustaceans is controlled by the X-organ/sinus gland complex, which is located within the eyestalks and secretes a neuropeptide, molt-inhibiting hormone (MIH), that inhibits ecdysone
production by a pair of Y-organs located in the cephalothorax (reviewed in Skinner, 1985; Hopkins, 1992; Chang et al.
