Phosphorylated Tyr(1138) binds STAT3 to mediate its tyrosine phosphorylation and transcriptional activation, while phosphorylated Tyr(985) binds the tyrosine phosphatase SHP-2 and reportedly mediates both activation of ERK kinases and inhibition of LRb-mediated STAT3 activation.

Thus, our data suggest that in addition to mediating SHP-2 binding and ERK activation during acute stimulation, Tyr(985) of LRb mediates feedback inhibition of LRb signaling by binding to LRb-induced SOCS3.

Western blotting confirmed a profound effect of insulin resistance and diabetes on Akt and ERK signaling in stented segments. p-ERK/p-Akt ratio in stented segments uniquely correlated with neointimal response (R2=0.888, P=0.04) in insulin-resistant and type 1 and 2 diabetic rats, but not in lean controls.

Moreover, glucokinase gene up-regulation requires the integrity of the juxtamembrane IR-B NPEY-motif and signaling via PI3K-C2alpha-like/PDK1/PKB, while c-fos gene activation requires the intact C-terminal YTHM-motif and signaling via PI3K Ia/Shc/MEK1/ERK.

Up-regulation of insulin-like growth factor 1 (IGF-1) expression and plasma levels and increasing IGF-1 receptor phosphorylation in muscle may explain the increased insulin receptor substrate 1, PI3K, and ERK phosphorylation in skeletal muscle.

Kinases, including IKKbeta, JNK, ERK, mTOR, and S6K, activated by the inducers of insulin resistance induce uncontrolled IRS serine phosphorylation.

Among them, ERK can be positively/negatively regulated by PPARgamma ligands, as in endothelial cells, where TZDs exert anti-inflammatory effects through a novel mechanism involving a rapid inhibition of ERK1/2 phosphorylation/activation.

Furthermore, dephosphorylation of the scaffold protein, KSR, at a critical serine residue is also synergistically promoted by GH and EGF, suggesting that GH sensitizes these cells to EGF-induced ERK activation by augmenting the actions of KSR in facilitating MEK-ERK activation.

Similarly specific synergy in ERK activation is also detected in human T47D breast cancer cells by cotreatment with PRL and PDGF.

Consistent with this synergy, PRL and PDGF also synergized for c-fos-dependent transactivation of a luciferase reporter gene in T47D cells, indicating that events downstream of ERK activation reflect this signaling synergy.

Insulin-induced egr-1 mRNA in HTC-IR cells was associated with corecruitment of IR signaling cascade (IR, SOS, Grb2, B-Raf, MEK, and ERK) to this gene.

In mouse LbetaT2 immortalized gonadotrophs, rosiglitazone treatment inhibited GnRH stimulation of the stress kinases p38MAPK and MAPKs/JNKs, but did not alter activation of ERKs, both in the presence and absence of activin.

CCK stimulated an association of Lyn with PKC-delta, Shc, p125(FAK) and PYK2 as well as with their autophosphorylated forms, but not with Cbl, p85, p130(CAS) or ERK 1/2.
