Apelin, an adipocyte-secreted factor upregulated by insulin, is increased in adipose tissue (AT) and plasma with obesity. Apelin was recently identified as a new player in the control of glucose homeostasis. However, the regulation of apelin and APJ (apelin receptor) expression in skeletal muscle in relation to insulin resistance or type 2 diabetes is not known. Thus we studied apelin and APJ e...
Apelin receptors, present on vascular smooth muscle cells, endothelium, and cardiomyocytes, are activated by the family of apelin peptides to elicit cardiovascular effects in experimental animals, but functional activity in humans has not been studied in detail. We detected low levels of apelin immunoreactivity in plasma of volunteers consistent with an autocrine/paracrine action and detected a...
KEY POINTS Dysfunctions in CNS regulation of arterial blood pressure lead to an increase in sympathetic nerve activity that participates in the pathogenesis of hypertension. The apelin-apelin receptor system affects arterial blood pressure homeostasis; however, the central mechanisms underlying apelin-mediated changes in sympathetic nerve activity and blood pressure have not been clarified. We ...
Lymphatic endothelium serves as a barrier to control fluid balance and immune cell trafficking to maintain tissue homeostasis. Long-term alteration of lymphatic vasculature promotes edema and fibrosis, which is an aggravating factor in the onset of cardiovascular diseases such as myocardial infarction. Apelin is a bioactive peptide that plays a central role in angiogenesis and cardiac contracti...
Vascular calcification, which results from a process osteoblastic differentiation of vascular smooth muscle cells (VSMCs), is a major risk factor for cardiovascular morbidity and mortality. Apelin is a recently discovered peptide that is the endogenous ligand for the orphan G-protein-coupled receptor, APJ. Several studies have identified the protective effects of apelin on the cardiovascular sy...
The cardiovascular profile of the apelin makes it a promising therapeutic target for heart failure and ischemic heart disease. However, it remains unknown whether apelin affect the clinical outcome of patients with ST elevation myocardial infarction (STEMI) and received percutaneous coronary intervention (PCI). We enrolled a total of 120 patients with acute STEMI who underwent primary PCI. Seru...
Apelin, the endogenous ligand of the APJ receptor, has been identified in a variety of tissues, including stomach, heart, skeletal muscle, and white adipose tissue. We sought to clarify the effects of apelin on body adiposity and the expression of uncoupling proteins (UCPs) in C57BL/6 mice. Treatment with ip apelin at a dose of 0.1 mumol/kg.d for 14 d decreased the weight of white adipose tissu...
Various studies have shown that eicosapentaenoic acid (EPA) has beneficial effects on obesity and associated disorders. Apelin, the ligand of APJ receptor also exerts insulin-sensitizing effects especially by improving muscle metabolism. EPA has been shown to increase apelin production in adipose tissue but its effects in muscle have not been addressed. Thus, the effects of EPA supplementation ...
Apelin-13 is extensively expressed in various tissues, particularly breast tissue. Apelin‑13 has been shown to promote tumor proliferation in various types of cancer, including hepatocellular, lung and ovarian cancer. However, the effect and molecular mechanism of apelin‑13 in breast cancer cells remains unclear. The present study investigated the effect of apelin‑13 on MCF‑7. Therefore, cell p...
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by the selective loss of motor neurons. Recent studies have implicated that chronic hypoxia and insufficient vascular endothelial growth factor (VEGF)-dependent neuroprotection may lead to the degeneration of motor neurons in ALS. Expression of apelin, an endogenous ligand for the G protein-coupled receptor APJ, is...
