S-nitrosation of the insulin receptor, insulin receptor substrate 1, and protein kinase B/Akt: a novel mechanism of insulin resistance.
Evidence demonstrates that exogenous nitric oxide (NO) and the NO produced by inducible nitric oxide synthase (iNOS) can induce insulin resistance in muscle. Here, we investigated whether thisExpand

Gut Microbiota Is a Key Modulator of Insulin Resistance in TLR 2 Knockout Mice
A genetic and pharmacological approach reveals novel insights into how changes in gut microbiota can subvert genetically predetermined phenotypes from lean to obese.

Western diet modulates insulin signaling, c-Jun N-terminal kinase activity, and insulin receptor substrate-1ser307 phosphorylation in a tissue-specific fashion.
The mechanisms by which diet-induced obesity is associated with insulin resistance are not well established, and no study has until now integrated, in a temporal manner, functional insulin actionExpand

Cold-induced PGC-1alpha expression modulates muscle glucose uptake through an insulin receptor/Akt-independent, AMPK-dependent pathway.
Peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1alpha) participates in control of expression of genes involved in adaptive thermogenesis, muscle fiber type differentiation,Expand

Cross-talk between the insulin and leptin signaling systems in rat hypothalamus.
OBJECTIVE To investigate whether insulin and leptin share common intracellular signal transduction pathways and to determine whether these hormonal signaling systems modulate each other's action inExpand

Exercise Improves Insulin and Leptin Sensitivity in Hypothalamus of Wistar Rats
Prolonged exercise of medium to high intensity is known to promote a substantial effect on the energy balance of rats. In male rats, moderately to severely intense programs lead to a reduction inExpand

Infliximab restores glucose homeostasis in an animal model of diet-induced obesity and diabetes.
TNF-alpha plays an important role in obesity-linked insulin resistance and diabetes mellitus by activating at least two serine kinases capable of promoting negative regulation of key elements of the insulin signaling pathway. Expand

Targeted disruption of iNOS prevents LPS-induced S-nitrosation of IRbeta/IRS-1 and Akt and insulin resistance in muscle of mice.
We have previously demonstrated that the insulin resistance associated with inducible nitric oxide synthase (iNOS) induction in two different models of obesity, diet-induced obesity and the ob/obExpand

A novel function of transferrin as a constituent of macromolecular activators of phagocytosis from platelets and their precursors.
Macromolecular activators of phagocytosis from platelets (MAPP:s-MAPP, 1500kDa and 1-MAPP, 300kDa) are glycoproteins released from human platelets and activate leukocyte phagocytosis via the Fc gammaExpand

Participation of prolactin receptors and phosphatidylinositol 3-kinase and MAP kinase pathways in the increase in pancreatic islet mass and sensitivity to glucose during pregnancy.
Prolactin (PRL) exerts its biological effects mainly by activating the Janus kinase/signal transducer and activator of transcription 5 (JAK/STAT5) signaling pathway. We have recently demonstratedExpand
