描述 |
Crustecdysone (20-Hydroxyecdysone) 是一种天然存在的蜕皮激素,源于露水草 Cyanotis arachnoides C.B.Clarke, 可控制节肢动物的蜕皮和变态,它通过 20E 核受体复合物 EcR-USP 抑制半胱天冬酶 (Caspase) 活性并诱导自噬 (autophagy)。Crustecdysone 在心血管系统中具有调节或保护作用。 |

Functions of nuclear receptor HR3 during larval-pupal molting in Leptinotarsa decemlineata (Say) revealed by in vivo RNA interference. Insect Biochem. Mol. Biol. 63 , 23-33, (2015)
Our previous results revealed that RNA interference-aided knockdown of Leptinotarsa decemlineata FTZ-F1 (LdFTZ-F1) reduced 20E titer, and impaired pupation. In this study, we characterized a putative …
