Tacrolimus and sirolimus are important immunosuppressive drugs used in human islet transplantation; however, they are linked to detrimental effects on islets and reduction of long-term graft function. Few studies investigate the direct effects of these drugs combined in parallel with single drug exposure. Human islets were treated with or without tacrolimus(More)
OBJECTIVE Increased oxidative stress and immune dysfunction are implicated in preeclampsia (PE) and may contribute to the two- to fourfold increase in PE prevalence among women with type 1 diabetes. Prospective measures of fat-soluble vitamins in diabetic pregnancy are therefore of interest. RESEARCH DESIGN AND METHODS Maternal serum carotenoids (α- and(More)
OBJECTIVE On the basis of the role of activin A in inflammation, atherogenesis, and glucose homeostasis, we investigated whether activin A could be related to glucometabolic abnormalities in patients with acute myocardial infarction (MI). RESEARCH DESIGN AND METHODS Activin A measurement and oral glucose tolerance tests (OGTTs) were performed in patients(More)
Nitric oxide (NO) is a key molecule in vascular headaches and the dura mater has been implicated as a tissue where vascular headache develops. Here we demonstrate expression, enzyme activity and cellular distribution of the intracellular receptor for NO, soluble guanylyl cyclase (sGC), in rat dura mater. Subcutaneous treatment of rats with the NO-donor(More)
Recent studies have described bone as an endocrine organ regulating glucose metabolism, with insulin signaling regulating osteocalcin secretion and osteocalcin regulating β cell function. We have previously demonstrated increased bone expression of TXNIP in patients with endogenous Cushing's syndrome (CS), and we hypothesized that TXNIP could contribute to(More)
AIMS/HYPOTHESIS Activation of inflammatory pathways is involved in the pathogenesis of type 2 diabetes mellitus. On the basis of its role in vascular inflammation and in metabolic disorders, we hypothesised that the TNF superfamily (TNFSF) member 14 (LIGHT/TNFSF14) could be involved in the pathogenesis of type 2 diabetes mellitus. METHODS Plasma levels of(More)
Islet transplantation has become a viable clinical treatment, but is still compromised by long-term graft failure. Exendin-4, a glucagon-like peptide 1 receptor agonist, has in clinical studies been shown to improve insulin secretion in islet transplanted patients. However, little is known about the effect of exendin-4 on other metabolic parameters. We(More)
OBJECTIVE To provide novel insights on mitochondrial respiration in β-cells and the adaptive effects of hypoxia. METHODS AND DESIGN Insulin-producing INS-1 832/13 cells were exposed to 18 hours of hypoxia followed by 20-22 hours re-oxygenation. Mitochondrial respiration was measured by high-resolution respirometry in both intact and permeabilized cells,(More)
