Disease relevance of 3-Dehydroecdysone

 

High impact information on 3-Dehydroecdysone

 

Biological context of 3-Dehydroecdysone

  • The enzyme responsible for hydroxylation at C-25 of the putative 3-dehydroecdysone precursor, 14-hydroxy-5 beta-cholest-7-en-3,6-dione, is also microsomal, while those mediating hydroxylations at C-22 and C-2 of 3,14,25-trihydroxy-5 beta-cholest-7-en-6-one are mitochondrial [6].
  • The prothoracic glands of the tobacco hornworm, Manduca sexta, respond to prothoracicotropic hormone (PTTH) by a regulatory pathway involving cAMP, protein phosphorylation, protein synthesis, and enhanced secretion of ecdysteroids including ecdysone and 3-dehydroecdysone [7].

Gene context of 3-Dehydroecdysone

 

Analytical, diagnostic and therapeutic context of 3-Dehydroecdysone

  • The prothoracic glands (PGs) of Lymantria dispar (day-5 female, last-stage larvae) produce both ecdysone and an ecdysteroid which has the same retention time on reverse-phase liquid chromatography (RPLC) as a known standard of 3-dehydroecdysone [10].
