[Effect of injection of a human gonadotropin on the synthesis and liberation of vitellogenin by adipose tissue of the marine crustacean isopod Idotea balthica basteri Audouin].

Human chorionic gonadotrophin (HCG) stimulates the rate of vitellogenin synthesis and release by fat bodies in puberal females of the marine Crustacean isopods Idotea balthica basteri. Moreover this effect is specific for vitellogenin: since 48 hr after the treatment, the rate of total protein synthesis, in treated females, is not significantly different from that of females injected with physiological medium, or with denaturated gonadotrophin.
