BACKGROUND/AIMS Metformin, the common medication for type II diabetes, has protective effects on cerebral ischemia. However, the molecular mechanisms are far from clear. Mitotic arrest deficient 2-like protein 2 (MAD2B), an inhibitor of the anaphase-promoting complex (APC), is widely expressed in hippocampal and cortical neurons and plays an important role in mediating high glucose-induced neur...
We aimed to determine whether epidermal growth factor receptor (EGFR) inhibition, in addition to a peroxisome proliferator-activated receptor gamma (PPAR γ ) agonist, prevents high-glucose-induced proximal tubular fibrosis, inflammation, and sodium and water retention in human proximal tubule cells exposed to normal glucose; high glucose; high glucose with the PPAR γ agonist pioglitazone or wit...
Introduction: In diabetes mellitus, stem cells are exposed to inappropriate conditions such as an increase of glucose in extracellular space, oxidative stress, and deprivation from growth factors (following ischemia). This study was aimed to evaluate the effect of these conditions on stem cells. Methods: Stem cells were isolated from subcutaneous adipose tissue of rats. The cells were maintaine...
Tumor cells survive under conditions of nutrient deprivation by mechanisms that are not fully understood. The MUC1 oncoprotein is aberrantly overexpressed by most human carcinomas and blocks oxidative stress-induced death. The present studies show that MUC1 inhibits the induction of necrosis in response to the deprivation of glucose. MUC1 suppressed glucose deprivation-induced increases in reac...
BACKGROUND The nuclear receptor peroxisome proliferator-activator gamma (PPARγ) is a useful therapeutic target for obesity and diabetes, but its role in protecting β-cell function and viability is unclear. METHODS To identify the potential functions of PPARγ in β-cells, we treated mouse insulinoma 6 (MIN6) cells with the PPARγ agonist pioglitazone in conditions of lipotoxicity, endoplasmic re...
BACKGROUND No pharmacologic therapy has conclusively proved to be effective for the treatment of nonalcoholic steatohepatitis, which is characterized by insulin resistance, steatosis, and necroinflammation with or without centrilobular fibrosis. Pioglitazone is a thiazolidinedione that ameliorates insulin resistance and improves glucose and lipid metabolism in type 2 diabetes mellitus. METHOD...
OBJECTIVE To investigate the influence of peroxisome proliferator-activated receptor-gamma (PPAR-gamma) gene variants on the response rate to therapy with the thiazolidinedione (TZD) pioglitazone, because in vitro studies have suggested that genetic variants of the PPAR-gamma gene may influence the drug efficacy of TZD. RESEARCH DESIGN AND METHODS A total of 131 patients were treated in an op...
AIMS To assess the long-term glycaemic effects, concomitant changes in medications and initiation of permanent insulin use (defined as daily insulin use for a period of > or = 90 days or ongoing use at death/final visit) with pioglitazone vs. placebo in diabetic patients receiving metformin or sulphonylurea monotherapy at baseline in the PROspective pioglitAzone Clinical Trial in macroVascular ...
Abstract Circulating nonadherent monocytes can migrate to extravascular sites by a process that involves adherence. Alterations in intracellular metabolism shape the immunological phenotype of phagocytes upon activation. To determine effect adherence on their metabolic and functional response human were stimulated with LPS under adherent conditions. Adherent (relative monocytes) produced less T...
A new experimental model for the study of two important aspects of ischemia, namely, oxygen and substrate deprivation, is proposed: the intact, beating fetal mouse heart in organ culture. This model offers long-term stability, ease and reproducibility of preparation, and the ability to manipulate experimental conditions. Hearts deprived of oxygen and glucose ceased beating immediately. After 3-...
