OBJECTIVES Protein phosphatase 4 (PP4) has been reported to be indispensable for cell proliferation and survival. Deletion of PP4 has been shown to induce abnormal and even lethal events in growth and development both in lower eukaryotes and in mammals. However, until now, effects of PP4 up-regulation have remained unclear. MATERIALS AND METHODS To test(More)
Simvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, has antioxidant and anti-inflammatory properties that are independent of lipid-lowering abilities. This experiment was carried out to explore the effects of simvastatin on apoptosis in vulnerable atherosclerotic plaques of apoE-deficient mice. Eight weeks-old apoE−/− mice were fed a(More)
By influencing the activity of the PI3K/AKT pathway, IL-6 acts as an important regulator of hepatic insulin resistance. miR-200s have been shown to control growth by regulating PI3K, but the role of miR-200s in the development of hepatic insulin resistance remains unclear. The present study showed that elevated serum concentration of IL-6 is associated with(More)
BACKGROUND The bispectral (BIS) index is a processed electroencephalogram (EEG) parameter with extensive validation and demonstrated clinical utility. The study aimed to investigate the correlation between the BIS index and the prognosis of patients with coma in the ICU. METHODS A total of 208 patients with coma in the ICU were enrolled in this study.(More)
AIMS N-acetylcysteine (NAC) has antioxidant and anti-inflammatory properties. To explore the mechanisms underlying atherosclerotic plaque stabilization induced by NAC, we examined the effects of NAC administration in apoE-deficient mice on the expression of the receptor of advanced glycation end products (RAGE), matrix metalloproteinases (MMPs) and the(More)
In type 2 diabetes, pancreatic β-cells cannot secret enough insulin compensate for insulin resistance, which are often accompanied by abnormality in lipid metabolism such as hypertriglyceridemia. It is reported that oxidative stress is involved in pancreatic β-cell dysfunction. However, molecular mechanisms linking between excessive generations of reactive(More)
Sodium/proton exchanger 1 (NHE1) plays an important role in the cardiomyocyte development. To study the effect of NHE1 activity in stem cells differentiation into cardiomyocytes, we treated P19 stem cells with dimethyl sulfoxide (DMSO) to initiate cardiomyocyte differentiation. In separate experiments, P19 cells were incubated with NHE1 specific inhibitor(More)
BACKGROUND Panax notoginseng saponins (PNS) extracted from the roots of panax notoginseng are free radical-scavenger, with an antioxidant property, capable of inhibiting expression of adhesion molecules and chemokines. This study was designed to test the effects of PNS administration in apolipoprotein (apo)-E-deficient mice on the activation of JNK,(More)
BACKGROUND There is increasing evidence that miRNAs are involved in cellular apoptosis. However, the specific role of miR-291b-3p in apoptosis has not been elucidated. In the present study, we investigated the effect of miR-291b-3p on NCTC1469 cell growth and apoptosis. METHODS Cell viability and apoptosis were examined in NCTC1469 cells transfected with(More)
BACKGROUND/AIMS IL-6 has been implicated in the pathogenesis of insulin resistance. MiR-301a plays an important role in various biological and pathological processes, including cellular development and differentiation, inflammation, apoptosis and cancer. However, whether miR-301a mediates IL-6-induced insulin resistance in hepatocytes remains unknown. (More)
