Genes acting in longevity-related pathways in the endoparasitoid, Pteromalus puparum.

abstract：:Bursicon is a neuropeptide that regulates cuticle sclerotization (hardening and tanning) via a G protein-coupled receptor. It consists of two subunits, an alpha and a beta. In the present study, we investigated the transcriptional expression and in situ localization of bursicon alpha and beta in the central nerve syst...
