Investigation of insulin-like growth factor-1 gene with egg-laying traits in the Muscovy duck (Cairina moschata)

Abstract: Muscovy duck (Cairina moschata) is characterized by broodiness, and egg-laying traits in this species should be of primary concern. As a member of the IGF superfamily of proteins, insulin-like growth factor-1 (IGF-1) is an important positive regulator of growth and gonad development in vertebrates. To explore the effect of IGF-1 on the growth hormone/insulin-like growth factors (GH/IGF) axis, we cloned and characterized IGF-1 of Muscovy duck. The expression level of IGF-1 was widely expressed in all the tested… Show more

“…The plasma protein encoded by Ttr is involved in thyroid hormone and vitamin A transport (Chang et al 1999). Its translated peptide is primarily secreted by the liver to stimulate normal growth in birds in response to hypothalamic stimuli (Wu et al 2016). Its translated peptide is primarily secreted by the liver to stimulate normal growth in birds in response to hypothalamic stimuli (Wu et al 2016).…”

“…The gene Igf1 is critical to growth hormone and thyroid hormone crosstalk. Its translated peptide is primarily secreted by the liver to stimulate normal growth in birds in response to hypothalamic stimuli (Wu et al 2016). These 3 genes were also down-regulated in CEHs following administration of other flame retardants such as TDCPP and tris (1, 3-dichloro-2propyl) phosphate (Farhat et al 2014).…”

“…In addition, different variants of IGF-1 genes, as well as variation in IGF-1 levels in poultry, resulted mainly in variation in productivity, i.e. different numbers of eggs produced or variation in egg quality (Hocking et al, 1994;Nagaraja et al, 2000;Wu et al, 2016).…”

“…Studies in female chicken and rabbit suggests that IGF-1 is also produced by the ovary, together with and under the influence of growth hormone, where they act as paracrine/autocrine regulators during follicular development (Ahumada-Solorzano et al 2016;Yoshimura et al 1994Yoshimura et al , 1996. In addition, different variants of IGF-1 genes, as well as variation in IGF-1 levels in poultry resulted mainly in variation in productivity; different numbers of eggs produced or variation in egg quality (Hocking et al 1994;Nagaraja et al 2000;Wu et al 2016).…”

“…IGF-1, predominantly synthesized by the liver, plays a clear regulatory role in growth and development, life span and various components of reproduction (Baker et al 1993;Daftary & Gore 2005;Dantzer & Swanson 2012;Hellström et al 2016;Holzenberger et al 2003;Liu et al 1993;Velazquez et al 2008). Though, recent studies in avian species have focused on growth and body condition (Lodjak et al 2014(Lodjak et al , 2017, evidence for a link between IGF-1 and reproduction in birds exist, but is restricted to poultry and mainly in relation to variation in productivity, such as the number of eggs and egg quality (Hocking et al 1994;Nagaraja et al 2000;Wu et al 2016). The ovary expresses IGF-1 receptors (Onagbesan et al 2009), but here IGF-1 might be mainly involved in steroidogenesis or differentiation and apoptosis in pre-hierarchical follicles, rather than rapid yolk development or VTG/VLDL receptor function (Onagbesan et al 2009;Woods et al 2007).…”
