Protein kinase C delta phosphorylates ecdysone receptor B1 to promote gene expression and apoptosis under 20-hydroxyecdysone regulation

, 2017
Significance The steroid hormone 20-hydroxyecdysone (20E) promotes apoptosis during larval-to-adult metamorphosis in insects. However, the mechanisms governing this process are unclear.

Decreased survival of mosquito cells after stable transfection with a Drosophila ecdysteroid response element: Possible involvement of a 40 kDa DNA binding protein

Journal of Insect Science, 2002
Homologous transfection systems provide a useful tool for characterizing promoters and other regulatory elements from cloned genes. We have used cultured Aedes albopictus C7-10 mosquito cells to evaluate expression of 20-hydroxyecdysone-inducible genes ...

Endocrine control of molting in the parasitic nematodes Dirofilaria immitis and Onchocerca lienalis: The effect of juvenile hormone-I, two juvenile hormone analogs, precocene II, 20-hydroxyecdysone, and noradrenaline

, 1992
The potential regulation of larval filarial molting by insect juvenile hormones/analogs (JH/JH-analogs) has not been intensively investigated. JH-I, JH-analogs, the JH antagonist precocene-II, and insect molting hormone 20-hydroxyecdysone, were ...
