Asano et al., J Biol Chem 2000
:
However, whereas the kinase activity of
p110beta , either endogenous or exogeneous, was markedly
enhanced by
insulin stimulation, only very small increases of the activity of p110alpha were observed
Chaussade et al., Biochem J 2007
:
Inhibition of
p110beta or p110delta alone was also not
sufficient to block
insulin signalling to PKB in these cells, but, when added in combination with p110alpha inhibitors, they are able to significantly attenuate insulin signalling ... Surprisingly, in J774.2 macrophage cells,
insulin signalling to PKB was
inhibited to a similar extent by inhibitors of p110alpha,
p110beta or p110delta ... These results provide evidence that
p110beta and p110delta can
play a role in
insulin signalling and also provide the first evidence that there can be functional redundancy between p110 isoforms
Guillermet-Guibert et al., Proc Natl Acad Sci U S A 2008
:
In fibroblasts, which express p110beta but not p110gamma,
p110beta mediated Akt activation by the GPCR ligands stromal cell derived factor, sphingosine-1-phosphate, and lysophosphatidic acid but not by the Tyr kinase ligands PDGF,
insulin , and insulin-like growth factor 1
Wang et al., Biochem J 1998
:
The hormone also caused a marked reorganization of actin filaments, which was prevented by cytochalasin D. Cytochalasin D also decreased significantly the
insulin dependent association of PI 3-kinase activity and the levels of insulin receptor substrate (IRS)-1, p85alpha and
p110beta with immunopurified GLUT4 containing compartments
