Biological context of PIK3R1

 

Anatomical context of PIK3R1

  • Pretreatment of these oocytes with wortmannin inhibited insulin-induced activation of PI 3-kinase in vivo [10].
  • We find that a class 1A PI3K catalytic activity is required for the definition of trunk mesoderm during the blastula stages, but is less important for endoderm and prechordal plate mesoderm induction or for organiser formation [11].
  • These results indicate that alphaPIX is activated by PI3-kinase, and is involved in the receptor mediated signaling leading to the activation of the kinase activity of PAK, and the migration of mesodermal cells on extracellular matrix [12].
  • However, our analysis of these pathways in gastrula stage embryos indicates that the MAP kinase pathway is required for Cdx gene expression, whereas the PI-3 kinase pathway is not [13].
  • These data suggest that SGK is a PI3K-dependent integrator of insulin and mineralocorticoid actions that interacts with ENaC subunits to control Na+ entry into kidney collecting duct cells [14].
