    Multilocal expression of B-type allatostatins in crickets (Gryllus bimaculatus)
    (2004) Wang, Junling; Meyering-Vos, Martina; Hoffmann, Klaus H
    B-type allatostatins (AST) inhibit the biosynthesis of juvenile hormone (JH) in vitro in crickets, but are also present in other insects, where they may bare different functions. By means of one-step RT-PCR and in situ hybridization recently, we could show that the mRNA of the gene is expressed in various cells of the central nervous system, but also in endocrine cells of the gut. The latter results corroborated a function of these peptides in regulating gut motility. Here we report on the expression of the gene in the ovary, the fat body and the flight muscles of female adult crickets, which suggests further putative functions of the B-type allatostatins beyond their role as brain–gut peptides.
