WebJun 16, 2016 · aegypti, the neuropeptide called ovary ecdysteroidogenic hormone (OEH) is also known to induce ovarian ecdysteroid biosynthesis and regulate egg maturation [47,48], while a role of OEH in GSC proliferation has not yet been examined. Somehow it seems that orthologues of OEH genes have been lost from the D. Webscript levels of these ecdysteroidogenic enzymes are the critical determinants of basal PG activity, and that the regulators of P450 gene expression are key players in the regulation of insect development. Prothoracicotropic hormone (PTTH) is a principal candidate for such regulators.8–10) PTTH has been gobbler race
