Sepsis-induced cardiac mitochondrial dysfunction involves altered mitochondrial-localization of tyrosine kinase Src and tyrosine phosphatase SHP2.

Numai utilizatorii înregistrați pot traduce articole

Our previous research demonstrated that sepsis produces mitochondrial dysfunction with increased mitochondrial oxidative stress in the heart. The present study investigated the role of mitochondria-localized signaling molecules, tyrosine kinase Src and tyrosine phosphatase SHP2, in sepsis-induced

Alterations in glucose-6-phosphatase gene expression in sepsis.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The influence of sepsis on the expression and activity of hepatic glucose-6-phosphatase (Glu-6-Pase) was examined during the early hyperglycemic phase and the later hypoglycemic phase. METHODS Sepsis was induced in anesthetized, fasted rats by cecal ligation and puncture, and liver

[Alteration of phospholamban phosphatase activity associated with cardiac sarcoplasmic reticulum during sepsis in rats].

Numai utilizatorii înregistrați pot traduce articole

In the present study, rat cardiac sarcoplasmic reticulum (SR) phospholamban (PLB) phosphatase was partially purified by chromatography on DEAE-Sephacel. This PLB phosphatase was indentical to phosphatase-1. It was shown on electrophoresis of SDS-PAGE autoradiography that the PLB phosphatase in rats

Protection against an Escherichia coli-induced sepsis by alkaline phosphatase in mice.

Numai utilizatorii înregistrați pot traduce articole

Alkaline phosphatase (AP) is a phosphate transferase present in bacteria and eukaryotes. In previous studies, we have shown that AP is able to dephosphorylate lipopolysaccharide (LPS) at physiological pH levels. Because LPS is the causative agent of gram-negative sepsis, we hypothesize that AP might

The potential of alkaline phosphatase as a treatment for sepsis-associated acute kidney injury.

Numai utilizatorii înregistrați pot traduce articole

Sepsis-associated acute kidney injury (AKI) is associated with a high attributable mortality and an increased risk of developing chronic kidney failure in survivors. As a successful therapy is, as yet, unavailable, a pharmacological treatment option is clearly warranted. Recently, two small phase II

Mitogen-activated protein kinase phosphatase 2 regulates the inflammatory response in sepsis.

Numai utilizatorii înregistrați pot traduce articole

Sepsis results from a dysregulation of the regulatory mechanisms of the pro- and anti-inflammatory response to invading pathogens. The mitogen-activated protein (MAP) kinase cascades are key signal transduction pathways involved in the cellular production of cytokines. The dual-specific phosphatase

Alkaline phosphatase as a treatment of sepsis-associated acute kidney injury.

Numai utilizatorii înregistrați pot traduce articole

Currently there are no pharmacological therapies licensed to treat sepsis-associated acute kidney injury (AKI). Considering the high incidence and mortality of sepsis-associated AKI, there is an urgent medical need to develop effective pharmacological interventions. Two phase II clinical trials

Map kinase phosphatase 5 protects against sepsis-induced acute lung injury.

Numai utilizatorii înregistrați pot traduce articole

Mitogen-activated protein kinases (MAPKs) play a critical role in inflammation. Although activation of MAPK in inflammatory cells has been studied extensively, much less is known about the inactivation of these kinases. MAPK phosphatase 5 (MKP5) is a member of the dual-specificity phosphatase family

Alkaline phosphatase treatment improves renal function in severe sepsis or septic shock patients.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Alkaline phosphatase (AP) attenuates inflammatory responses by lipopolysaccharide detoxification and may prevent organ damage during sepsis. To investigate the effect of AP in patients with severe sepsis or septic shock on acute kidney injury. METHODS A multicenter double-blind,

Reduced Insulin Resistance Contributes to the Beneficial Effect of Protein Tyrosine Phosphatase-1B Deletion in a Mouse Model of Sepsis.

Numai utilizatorii înregistrați pot traduce articole

Hyperglycemia is a common feature of septic patients and has been associated with poor outcome and high mortality. In contrast, insulin has been shown to decrease mortality and to prevent the incidence of multiorgan failure but is often associated with deleterious hypoglycemia. Protein Tyrosine

Sepsis-induced depression of rat glucose-6-phosphatase gene expression and activity.

Numai utilizatorii înregistrați pot traduce articole

Sepsis in rats decreases the hepatic expression of the gluconeogenic enzyme glucose-6-phosphatase (G6Pase). The aim of this study was to investigate the relationship among G6Pase transcription, mRNA, enzymatic activity, and serum glucose levels at different intervals during mild or fulminant sepsis.

Redox signaling and splicing dependent change in myosin phosphatase underlie early versus late changes in NO vasodilator reserve in a mouse LPS model of sepsis.

Numai utilizatorii înregistrați pot traduce articole

Microcirculatory dysfunction may cause tissue malperfusion and progression to organ failure in the later stages of sepsis, but the role of smooth muscle contractile dysfunction is uncertain. Mice were given intraperitoneal LPS, and mesenteric arteries were harvested at 6-h intervals for analyses of

Study protocol for a multicentre randomised controlled trial: Safety, Tolerability, efficacy and quality of life Of a human recombinant alkaline Phosphatase in patients with sepsis-associated Acute Kidney Injury (STOP-AKI).

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Acute kidney injury (AKI) occurs in 55-60% of critically ill patients, and sepsis is the most common underlying cause. No pharmacological treatment options are licensed to treat sepsis-associated AKI (SA-AKI); only supportive renal replacement therapy (RRT) is available. One of the

Determination of protein phosphatase type 2A in monocytes from multiple trauma patients: a potential biomarker for sepsis.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Protein phosphatase type 2A (PP2A) can downregulate c-Jun N-terminal kinase (JNK) expression in monocytes stimulated by lipopolysaccharide. However, this effect has not been evaluated in patients with sepsis. We sought to determine whether PP2A/JNK pathway is involved in sepsis and

Programmed cell death receptor ligand 1 modulates the regulatory T cells' capacity to repress shock/sepsis-induced indirect acute lung injury by recruiting phosphatase SRC homology region 2 domain-containing phosphatase 1.

Numai utilizatorii înregistrați pot traduce articole

We recently reported that adoptively transferred (AT) exogenous CD4+ CD25+ regulatory T cells (Tregs) to wild-type (WT) mice can directly act to repress shock/sepsis-induced experimental indirect acute lung injury (iALI), and this is mediated in part by programmed cell death receptor 1 (PD-1). In
