Chronic thromboembolic pulmonary hypertension (CTEPH) is an entity of PH that not only limits patients quality of life but also causes significant morbidity and mortality. The treatment of choice is pulmonary endarterectomy. However numerous patients do not qualify for pulmonary endarterectomy or present with residual vasculopathy post pulmonary endarterectomy and require specific vasodilator t...

Apelin is a regulatory peptide, identified as an endogenous ligand of the Apelin receptor (APJ). Both the apelin and the APJ were detected in brain, lung, heart, mammary gland, kidney, placenta, adipose tissues and the gastrointestinal tract. Apelin is considered an important regulatory gut peptide with a potential physiological role in gastrointestinal cytoprotection, regulation of food intake...
BACKGROUND Although accumulating data has implicated a role for the Apelinergic system in cirrhosis, the role of Apelin during different stages of fibrogenesis has not been clarified, whereas no studies have been conducted on its expression in human hepatocellular carcinoma (HCC). This study aimed to elucidate its role in hepatic remodelling and carcinogenesis. METHODS Immunolocalization of A...
Studies have shown significant cardiovascular effects of exogenous apelin administration, including the potent activation of cardiac contraction. However, the role of the endogenous apelin-APJ pathway is less clear. To study the loss of endogenous apelin-APJ signaling, we generated mice lacking either the ligand (apelin) or the receptor (APJ). Apelin-deficient mice were viable, fertile, and sho...
INTRODUCTION Cardiovascular disease is classes of diseases or illness that mainly involves blood vessel which include veins, arteries and capillaries or the heart or the both. Etiology for the cardiovascular diseases is diverse but most common etiology is atherosclerosis and hypertension. Most common risk factors that contribute cardiovascular diseases are, Hypertension, Radiation therapy-repor...
Background—Apelin, the endogenous ligand for the novel G protein– coupled receptor APJ, has major cardiovascular effects in preclinical models. The study objectives were to establish the effects of acute apelin administration on peripheral, cardiac, and systemic hemodynamic variables in healthy volunteers and patients with heart failure. Methods and Results—Eighteen patients with New York Heart...
Apelin, a new bioactive peptide, was identified as an endogenous ligand for APJ (Angiotensin II receptor-like 1). Apelin and its receptor have an abundant distribution in central nervous system and peripheral tissues, including liver. Apelin/APJ has diverse physiological and pathological effects, including regulation of cardiovascular function, angiogenesis, fluid homeostasis and so on. Apelin/...
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...
Apelin, an endogenous ligand for APJ receptor, has been reported to be upregulated in paraventricular nucleus (PVN) following stress. Central apelin is known to stimulate release of corticotropin-releasing factor (CRF) via APJ receptor. We tested the hypothesis that stress-induced gastrointestinal (GI) dysfunction is mediated by central apelin. We also assessed the effect of exogenous apelin on...
