Coexpression of IRS-1 or IRS-1F-895 with the insulin receptor was required for insulin-stimulated mitogenesis in 32-D cells, while expression of the insulin receptor alone was sufficient to mediate insulin-stimulated tyrosine phosphorylation of Shc and activation of p21ras and mitogen-activated protein (MAP) kinase.
|

|
The Shc-GRB-2 complex formed during insulin stimulation is a possible mediator of p21ras and MAP kinase activation in IRS-1-deficient 32-D cells.
|

|
Interestingly, IRS-1, but not IRS-1F-895, enhanced the stimulation of MAP kinase by insulin in 32-D cells expressing insulin receptors.
|

|
Thus, IRS-1 contributes to the stimulation of MAP kinase by insulin, probably through formation of the IRS-1-GRB-2 complex at Tyr-895.

In contrast, the treatment with 23 nM TNF-alpha failed to phosphorylate either IGF-I receptor beta-subunit or IRS-1 but did phosphorylate MAP kinase as much as IGF-I did.
|
14 |
8803477
|
Despite a similar extent to which TNF-alpha induced MAP kinase phosphorylation as IGF-I did, TNF-alpha stimulated glucose uptake less compared to IGF-I.

Scavenger receptors have only been shown to bind proteins modified by AGE to a much higher extent than found in vivo. 80K-H phosphoprotein is involved in FGFR3 signal transduction to MAP kinase, and may be involved in AGE-receptor signal transduction.

By using inhibitors of the different signaling pathways evoked by insulin-receptor binding, it has been shown that the biosynthesis of PAI-1 is due to phosphatidylinositol (PI) 3-kinase activation, followed by protein kinase C and ultimately by mitogen-activated protein (MAP) kinase activation and extracellular signal-regulated kinase 2 phosphorylation.

The enhancing effect of angiotensin AT(1) receptor antagonist on skeletal muscle glucose uptake may be attributable to MAP kinase activation or other mechanisms rather than phosphatidylinositol 3-kinase activation.

26 |

|
Inhibition of phosphatidylinositol 3-kinase with wortmannin blocked the ability of insulin to stimulate increased expression of endothelial nitric-oxide synthase, did not affect insulin-induced activation of MAP kinase, and increased the effects of insulin on prenylation of Ras and Rho proteins.

Finally, using in vitro cellular models of amyloid precursor protein (APP)-processing and Abeta generation/clearance, we confirmed that human recombinant (hr)CTGF may increase Abeta1-40 and Abeta1-42 peptide steady-state levels, possibly through a mechanism that involves gamma-secretase activation and decreased insulin-degrading enzyme (IDE) steady-state levels in a MAP kinase (MAPK)/ phosphatidylinositol 3-kinase (PI-3K)/protein kinase-B (AKT)1-dependent manner.

IkappaB kinase-(IKK)-beta inhibition prevented mitogen-activated protein (MAP) kinase kinase (MEK)/ERK1/2 activation in response to interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha but not insulin in 3T3-L1 and human adipocytes, suggesting that IKKbeta regulated a MAP kinase kinase kinase (MAP3K) involved in ERK1/2 activation induced by inflammatory cytokines.
