Biological Activity
| Description | 20-Hydroxyecdysone (Ecdysterone, 20E, B-ecdysone, Commisterone, Crustecdysone) is a naturally occurring ecdysteroid hormone which controls the ecdysis (moulting) and metamorphosis of arthropods.20-Hydroxyecdysone (Ecdysterone, 20E) inhibits caspase activity and induces autophagy via the 20E nuclear receptor complex, EcR-USP. | |

| Targets |
|
|
| In vitro | In H4IIE cell culture, 20-Hydroxyecdysone treatment decreases expression of phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase), reduces glucose production, and induces Akt2 phosphorylation sensitive to the phosphoinositide-3 kinase pathway-specific inhibitor LY-294002. [1] 20-Hydroxyecdysone treatment before or after CoCl2 exposure significantly ameliorates CoCl2-induced cellular injuries. 20-Hydroxyecdysone dramatically reduces the CoCl2-induced production of reactive oxygen species (ROS), decreases the depolarization of the mitochondrial membrane, inhibits the release of cytochrome c into the cytosol, increases the Bax/Bcl-2 ratio, and eliminates the CoCl2-induced activation of caspase-3. [2] 20-Hydroxyecdysone inhibits NF-κB activation in HeLa cells stably transfected with an IL-6-bound reporter gene with IC50 of 31.8 µM. [3] In vitro treatment of larval fat body tissues with 20-Hydroxyecdysone upregulates the apoptotic genes including Apaf-1, Nedd2 like1, Nedd2 like2, ICE1, ICE3, ICE5, Arp, and IAP. [4] 20-Hydroxyecdysone reverses TGF-β1-induced increase in intracellular and extracellular fibronectin, and reverses TGF-β1-induced down-regulation of Smad7. Additionally, 20-Hydroxyecdysone significantly attenuates TGF-β1-induced upregulation of Smad2/3 and pSmad2/3, and downregulation of E-Cadherin. Moreover, 20-Hydroxyecdysone dramatically suppresses TGF-β1-induced increases in the expression of Snail. [5] | |
| In vivo | Oral administration of 20-Hydroxyecdysone (10 mg/kg/day for 13 weeks) ameliorates obesity and insulin resistance in C57BL/6J mice fed a high-fat diet and produces a significant decrease of body weight gain and body fat mass compared with untreated animals. In addition, plasma insulin levels and glucose tolerance are significantly lowered by 20-Hydroxyecdysone treatment. These changes are accompanied by the reduced hepatic expression of PEPCK and G6Pase and increased adiponectin production by visceral fat tissue. [1] In the fat body of the silkworm, Bombyx mori, injection of 20-Hydroxyecdysone into day 2 of fifth instar larvae significantly induces apoptosis and upregulates apoptotic genes after 6 hours of treatment. [4] 20-Hydroxyecdysone (5 mg/kg/day) treatment does not have potent anabolic properties, however, a muscle-specific increase is observed and genes are identified to provide an explanation for the muscle accretion.
