Induction of insulin resistance by the adipokines resistin, leptin, plasminogen activator inhibitor-1 and retinol binding protein 4 in human megakaryocytes

open access: yesHaematologica, 2012
Background In normal platelets, insulin inhibits agonist-induced Ca2+ mobilization by raising cyclic AMP. Platelet from patients with type 2 diabetes are resistant to insulin and show increased Ca2+ mobilization, aggregation and procoagulant activity. We

Effect of diet-induced obesity on protein expression in insulin signalling pathways of skeletal muscle in male Wistar rats [PDF]

open access: yes, 2012
BACKGROUND: The prevalence of diet-induced obesity is increasing globally, and posing significant health problems for millions of people worldwide. Diet-induced obesity is a major contributor to the global pandemic of type 2 diabetes mellitus.

Insulin receptor substrates-5 and -6 are poor substrates for the insulin receptor

open access: yesMolecular Medicine Reports, 2009
Insulin receptor substrates (IRS)-5 and -6 are two recently identified members of the IRS family. We investigated their roles as insulin receptor substrates and compared them with Src-homology-2-containing (Shc) protein, a well-established substrate. Bioluminescence resonance energy transfer (BRET) experiments showed no interaction between the receptor

Caspase-mediated Cleavage of Insulin Receptor Substrate [PDF]

open access: yesJournal of Biological Chemistry, 2004
Apoptosis is an important mechanism for maintaining tissue homeostasis. The efficient induction and execution of apoptosis are essential for cell clearance in specific developmental situations. Insulin-like growth factor (IGF)-I is a survival factor for epithelial cells in the mammary gland, and its withdrawal or inhibition leads to apoptosis.

Tissue-specific regulation of IRS-1 in unilaterally nephrectomized rats

open access: yesBrazilian Journal of Medical and Biological Research, 1997
Insulin stimulates the tyrosine kinase activity of its receptor, resulting in the phosphorylation of its cytosolic substrate, insulin receptor substrate 1 (IRS-1).

The Common Single Cause of Chronic Multi-Hormonal Resistance in Oxidative Stress

open access: yesAntioxidants, 2022
In diseases with concomitant oxidative stress, chronic multi-hormonal resistances could be detected. The most conspicuous component of these resistances is insulin resistance, but also leptin, erythropoietin, acetylcholine, triiodothyronine and glucagon ...

53BP2S, Interacting with Insulin Receptor Substrates, Modulates Insulin Signaling [PDF]

open access: yesJournal of Biological Chemistry, 2007
It is well known that insulin receptor substrates (IRS) act as a mediator for signal transduction of insulin, insulin-like growth factors, and several cytokines. To identify proteins that interact with IRS and modulate IRS-mediated signals, we performed yeast two-hybrid screening with IRS-1 as bait.

Mechanism by Which Fatty Acids Inhibit Insulin Activation of Insulin Receptor Substrate-1 (IRS-1)-associated Phosphatidylinositol 3-Kinase Activity in Muscle*

open access: yesJournal of Biological Chemistry, 2002
Recent studies have demonstrated that fatty acids induce insulin resistance in skeletal muscle by blocking insulin activation of insulin receptor substrate-1 (IRS-1)-associated phosphatidylinositol 3-kinase (PI3-kinase). To examine the mechanism by which

Insulin receptor substrate 2 is required for testicular development. [PDF]

open access: yesPLoS ONE, 2013
Insulin receptor substrate (IRS) proteins are key mediators of insulin and insulin-like growth factor (IGF) signalling. In mice, deletion of Irs1 is associated with profound growth retardation and increased longevity whereas Irs2-deficiency causes ...

Insulin Regulation of Membrane-associated Insulin Receptor Substrate 1 [PDF]

open access: yesJournal of Biological Chemistry, 1995
Insulin stimulation of 3T3-L1 adipocytes results in rapid activation of the insulin receptor tyrosine kinase followed by autophosphorylation of the receptor and phosphorylation of insulin receptor substrate 1 (IRS-1), its major substrate. The insulin receptor resides mostly at the cell surface of 3T3-L1 adipocytes under basal conditions, while about ...
