Rodrigues, Marisa A. Flatt, Thomas 2016-08-01 In most animals reproduction trades off with somatic maintenance and survival. Physiologically this trade-off is mediated by hormones with opposite effects on reproduction and maintenance. In many insects, this regulation is achieved by an endocrine network that integrates insulin-like/IGF-1 signaling (IIS), juvenile hormone (JH), and the yolk precursor vitellogenin (Vg) (or, more generally, yolk proteins [YPs]). Downregulation of this network promotes maintenance and survival at the expense of reproduction. Remarkably, however, queens of highly eusocial social insects exhibit both enormous reproductive output and longevity, thus escaping the trade-off. Here we argue — based on recent evidence — that the proximate reason for why eusocial insects can decouple this trade-off is that they have evolved a different ‘wiring’ of the IIS-JH-Vg/YP circuit. application/pdf https://folia.unifr.ch/global/documents/307560 https://folia.unifr.ch/documents/307560/files/2016_eut.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.cois.2016.04.013 info:eu-repo/semantics/openAccess License undefined Current Opinion in Insect Science. - 2016, vol. 16, p. 1–8 info:eu-repo/classification/udc/57 Endocrine uncoupling of the trade-off between reproduction and somatic maintenance in eusocial insects http://purl.org/coar/resource_type/c_6501
