Apelin is highly expressed in the lungs, especially in the pulmonary vasculature, but the functional role of apelin under pathological conditions is still undefined. Hypoxic pulmonary hypertension is the most common cause of acute right heart failure, which may involve the remodeling of artery and regulation of autophagy. In this study, we determined(More)
OBJECTIVE To assess the global changes in and characteristics of the transcriptome of long noncoding RNAs (LncRNAs) in heart tissue, whole blood and plasma during heart failure (HF) and association with expression of paired coding genes. METHODS Here we used microarray assay to examine the transcriptome of LncRNAs deregulated in the heart, whole blood,(More)
I t has been unclear whether there is a pathway that regulates plasma glucose through the action of peripheral tissue of apelin with the secretory function of insulin, which exerts a control in adipo-cytes in addition to the direct regulation of plasma glucose. Our study was designed to identify the changes in plasma apelin levels in newly diagnosed type 2(More)
OBJECTIVE Adipose tissue expressed endogenous cystathionine gamma lyase (CSE)/hydrogen sulfide (H2S) system. H2S precursor inhibited catecholamine stimulated lipolysis. Thus, we hypothesized that CSE/H2S system regulates lipolysis which contributed to the pathogenesis of insulin resistance. METHODS We treated rat adipocyte with DL-propargylglycine (PAG, a(More)
Previous studies have demonstrated that β2-adrenergic receptors (β2ARs) can be phosphorylated by G protein-coupled receptor kinases (GRKs) and protein kinase A (PKA), affecting β2AR internalization and desensitization. However, the exact physiological function of β2ARs in cardiomyocytes is unknown. In this study, we showed that neonatal mouse cardiomyocytes(More)
OBJECTIVE The aim of this study was to determine whether TPCN2 genetic variants are associated with type 2 diabetes and to elucidate which variants in TPCN2 confer diabetes susceptibility in the Chinese population. RESEARCH DESIGN AND METHODS The sample population included 384 patients with type 2 diabetes and 1468 controls. Anthropometric parameters,(More)
Apelin, a small bioactive peptide, plays an important role in the pathogenesis of mood disorders through the endogenous ligand APJ. Although the anxiolytic effect of apelin is well established, the mechanisms are poorly understood. In this study, we hypothesized that apelin played an anxiolytic role in chronic normobaric hypoxia (CNH)-induced anxiety like(More)
In this paper, we study the effect of stimulation of the genioglossus with percutaneous biphasic electrical pulses on patients with the obstructive sleep apnea syndrome (OSAS). The experiment was conducted in 22 patients clinically diagnosed with OSAS. The patients were monitored with polysomnography (PSG) in the trial. When the sleep apnea was detected,(More)
BACKGROUND The objective of this study was to assess the effects of metformin monotherapy or combined treatment with a dipeptidyl peptidase-4 inhibitor (vildagliptin) on apelin levels in patients with type 2 diabetes mellitus. METHODS Twenty-five patients with poor glycemic control (glycosylated hemoglobin >6.5% [48 mmol/mol]) taking 1,000 mg of metformin(More)
This study aims to investigate whether inflammation mediated by NF-κB activation is involved in the induction of anxiety-like behavior in chronic normobaric hypoxia (CNH) exposed rats and to investigate the underlying mechanism. To this end, rats were exposed in a normobaric hypoxic chamber with a fraction of inspired oxygen (FIO2) of ∼ 10%, 23 h/d,(More)
