BACKGROUND Essential hypertension has been recognized as a disease resulting from a combination of environmental and genetic factors. Recent studies demonstrated that microRNAs (miRNAs) are involved in cardiac hypertrophy and heart failure. However, little is known about the roles of miRNAs in essential hypertension. METHODS AND RESULTS Using(More)
Evidence suggests Ginsenoside Rd (GSRd), a biologically active extract from the medical plant Panax Ginseng, exerts antioxidant effect, decreasing reactive oxygen species (ROS) formation. Current study determined the effect of GSRd on myocardial ischemia/reperfusion (MI/R) injury (a pathological condition where ROS production is significantly increased) and(More)
The Arabidopsis Ethylene-Insensitive 2 (EIN2) gene has been shown to be involved in the regulation of abiotic and biotic stresses, including ozone stress, high salt, oxidative stress and disease resistance. However, little is known about the role of EIN2 gene in lead (Pb) resistance in Arabidopsis. In this study, we showed that EIN2 gene is required for(More)
AIMS Mesenchymal stem cells (MSCs) can ameliorate myocardial infarction (MI) injury. However, older-donor MSCs seem less efficacious than those from younger donors, and the contributing underlying mechanisms remain unknown. Here, we determine how age-related expression of pigment epithelium-derived factor (PEDF) affects MSC therapeutic efficacy for MI. (More)
Vascular complications are the major causes of death in patients with diabetes, and endothelial dysfunction is the earliest event in vascular complications of diabetes. It has been reported that plasma irisin level is significantly reduced in patients with type 2 diabetic patients. The present study aimed to investigate whether irisin improved endothelial(More)
APOBEC3G (A3G), a member of cytidine deaminase family, has potent anti-human immunodeficiency virus type 1 (HIV-1) activity. It has been demonstrated that alpha interferon (IFN-alpha) can significantly enhance the expression of A3G in human primary resting CD4(+) T-cells, macrophages and primary hepatocytes, subsequently decreasing their viral(More)
The ability of N-n-butyl haloperidol iodide (F2) to cause vasodilation, and thereby produce a cardioprotective effect, has been well documented. The aim of this study was to investigate whether F2 might act as a Ca2+ antagonist. Myocytes were obtained from rat heart, and the whole-cell patch-clamp technique was used to record Ca2+ current. Laser scanning(More)
Interferon regulatory factor 8 (IRF8) is known to affect the innate immune response, for example, by regulating the differentiation and function of immune cells. However, whether IRF8 can influence cardiac hypertrophy is unknown. Here we show that IRF8 levels are decreased in human dilated/hypertrophic cardiomyopathic hearts and in murine hypertrophic(More)
AIMS Dickkopf-3 (DKK3), a secreted protein in the Dickkopf family, is expressed in various tissues, including the heart, and has been shown to play an important role in tissue development. However, the biological function of DKK3 in the heart remains largely unexplored. This study aimed to examine the role of DKK3 in pathological cardiac hypertrophy. (More)
OBJECTIVES Vascular insulin resistance plays a crucial pathogenic role in the development of genetic hypertension. However, it is not known whether hypertension-associated myocardial insulin resistance also exists, and whether this is involved in the development of related diseases, such as hypertensive heart failure. The present study aimed to determine(More)
