Text-mined interactions from Literome

Patti et al., Ann N Y Acad Sci 1999 (Diabetes Mellitus, Type 2...) : Similarly, activation of the hexosamine pathway by infusion of glucosamine also reduces insulin stimulated phosphorylation of IRS proteins, activation of PI3-kinase , and activation of glycogen synthase
Hemi et al., J Biol Chem 2002 (Insulin Resistance...) : Similar to TNF, cycloheximide and anisomycin stimulated serine phosphorylation of IRS-1 and IRS-2, reduced their ability to interact with the insulin receptor, inhibited the insulin induced tyrosine phosphorylation of IRS proteins, and diminished their association with phosphatidylinositol 3-kinase (PI3K)
Hers et al., Biochem J 2002 : In contrast, inhibition of PI 3-kinase led to a decrease in insulin stimulated p85 binding to IRS-3 , but had no effect on SHP-2 binding
Kaburagi et al., Biochem Biophys Res Commun 2003 : Overexpressed IRS-3 as well as IRS-1 enhanced phosphoinositide (PI) 3-kinase activity in response to insulin and increased phosphorylation of protein kinase B (PKB) at S473 and phosphorylation of one of the members of the forkhead transcription factor FKHRL1 on T32 in both insulin untreated and -treated states
Folli et al., J Biol Chem 1992 : Thus, IRS-1 phosphorylation plays a significant role in the activation of PI 3-kinase in vivo by insulin
Luna et al., Diabetologia 2006 (Diabetes Mellitus, Type 2) : In contrast, IRS-1 dependent phosphatidylinositol (PI) 3-kinase activity and Ser473 phosphorylation of protein kinase B were not altered by metformin therapy, whereas the responsiveness of muscle aPKC to PI-3,4,5- ( PO ( 4 ) ) ( 3 ), the lipid product of PI 3-kinase, was improved
Biswas et al., Molecular vision 2009 : Together, these data indicate that disruption of PDGF receptor signaling compromises the pro-survival effect of insulin induced IRS dependent PI 3-kinase/Akt signaling in RGCs, and that the maintenance of PDGF induced PI 3-kinase/Akt signaling is critical for the survival of retinal neuronal cells
Hügl et al., J Biol Chem 1998 : Thus, glucose and IGF-I induced beta-cell proliferation were mediated via a signaling mechanism that was facilitated by mitogen activated protein kinase but dependent on IRS mediated induction of PI 3'-kinase activity and downstream activation of p70 ( S6K )
Anai et al., J Biol Chem 1998 (Insulin Resistance) : In contrast, IRS-3 is located mainly in the plasma membrane ( PM ) fraction and contributes to PI 3-kinase activation in the PM fraction
