Ecdysteroid definition

20E (and other ecdysteroids) are used in biochemistry research as inducers in transgenic animals, whereby if you put a new gene into an animal so that its expression is under the control of an introduced ecdysone receptor , then adding or removing 20-hydroxyecdysone from the animal's diet gives a convenient way to turn the inserted gene on or off (see Ecdysone receptor ). At usual doses, 20-hydroxyecdysone appears to have little or no effect on animals that do not have extra genes inserted; it also has high bioavailability when taken orally, so it is useful for determining whether the transgene has been taken up effectively. [ 8 ] For uses in gene therapy , it may be necessary to investigate more thoroughly the natural sources of ecdysteroids in humans (which appear to include dietary phytoecdysteroids , gut flora , helminth infections , and other diseases ).
