Associations of IGF2 with chemical compounds

 

Physical interactions of IGF2

  • The developmental patterns of [125I]IGF-I and [125I]IGF-II binding to brain were similar, and IGF-I showed approximately a 2-fold higher binding than IGF-II; there was a sharp increase from days 3 to 6, and a subsequent gradual fall during the second and third weeks of ontogeny [22].
  • Both IGF-I and IGF-II ligands in the Western ligand blot revealed the most intense binding at 30 kDa for plasma obtained from chickens with restricted food intake [23].
 

Regulatory relationships of IGF2

  • IGF-I and IGFBP concentrations in the plasma of young broiler chickens were influenced by nutritional state but IGF-II concentrations were not [23].
  • The role of protein kinase A and cyclin-dependent (CDC2) kinase in the control of basal and IGF-II-induced proliferation and secretory activity of chicken ovarian cells [24].
 

Other interactions of IGF2

  • Half-maximal responses required 0.2 nM IGF2 or IGF1, or 20 nM insulin [25].
  • Insulin-like growth factor-I and IGF-II peaked at 14E [18].
  • Potential role for insulin-like growth factor II and vitronectin in the endothelial-mesenchymal transition process [11].
  • In contrast to the monophasic profile for IGF-I, plasma concentrations of IGF-II were maximal on Day 10.5 of incubation and declined to a nadir on Day 17.5 of incubation [26].
  • A striking observation concerning the expression profiles of both IGF-II and IGFBP-5 at early stages of chick embryogenesis is that both these genes are expressed asymmetrically in a pattern similar to that of Sonic Hedgehog (Shh) [27].
