Abstract Background and Aims Chronic kidney disease (CKD) is a leading cause of global morbidity mortality independently associated with cardiovascular disease. Indeed, patients CKD are more likely to die than they progress failure. Despite current standard care, outcomes remain poor newer therapies needed. Apelin, an endothelium-dependent vasodilator potent inotrope, potential novel treatment ...

Aim: A testicular germ cell tumour is not observed widely, but its incidence and mortality rates have increased in recent years. One of the most common forms this seminoma. Germ neoplasia situ (GCNIS) precursor The apelin/APJ axis many cancers a pathway that plays an active role angiogenesis, lymphangiogenesis, growth, migration. This study investigated cellular distributions apelin APJ protein...

Objective. The present study was designed to compare serum levels of apelin between lean PCOS women and healthy women with regular menses. Study Design. A total of 30 lean patients with PCOS and 30 healthy subjects were included in this study. Serum apelin levels were compared between groups. Results. Serum apelin levels in lean PCOS patients were not significantly different from the control su...

BACKGROUND During acute myocardial infarction, phosphorylated TnI levels, Ca2+ sensitivity and ATPase activity are decreased in the myocardium, and the subsequent elevation in Ca2+ levels activates protease I (caplain I), leading to the proteolytic degradation of troponins. Concurrently, the levels of apelin and APJ expression are increased by limiting myocardial injury. METHODS In this prosp...

Background: Apelin has recently been identified as an analgesic agent and a novel neuropeptide. On the other hand, it has been shown that exercise can lead to reduced pain in morphine-dependent patients. Objectives: Therefore, the aim of this study was to evaluate apelin and pain threshold changes in healthy and morphine-dependent rats in response to two exercise paradigms. Materials and Method...

Recently, a paper by Kim et al. [1] in Nature Medicine magazine in January, 2013 showed that apelin (also known as APLN) inhibits fibroblast growth factor 2 (FGF2) and FGF receptor 1 (FGFR1) expression to ameliorate pulmonary hypertension by regulating the expression of miR-424 and miR-503. This study revealed the molecular mechanism of apelin in inhibiting the process of pulmonary arterial hyp...

Apelin, a (neuro)vasoactive peptide, plays a prominent role in controlling body fluid homeostasis and cardiovascular functions. In animal models, experimental data demonstrate that intracerebroventricular injection of apelin into lactating rats inhibits the phasic electrical activity of arginine vasopressin (AVP) neurons, reduces plasma AVP levels, and increases aqueous diuresis. In the kidney,...

Apelin acts via the G protein-coupled apelin receptor (APJ) to mediate effects on cardiovascular and fluid homeostasis. G protein-coupled receptor (GPCR) trafficking has an important role in the regulation of receptor signalling pathways and cellular functions, however in the case of APJ the mechanisms and proteins involved in apelin-induced trafficking are not well understood. We generated a s...

Adipocytes are not only for energy storage, but are also functionally active cells, producing biologically active peptides called adipocytokines. Adipocytokines control nutrition, thermogenesis, immunity, thyroid and reproductive hormones, and neuroendocrine functions. One of the most important new members of this family is apelin. In patients with thyroid dysfunctions, there are usually change...

Heart failure is a chronic, progressive disease in which the overexpression of biologically active molecules and neurohomonal activation are the key factors of the evolution and natural history. The apelin-APJ system is a newly discovered molecular pathway and the RAAS counterbalance is its principal effect. The apelin is a potent inotrope, vasodilator and diuretic with crucial cardioprotective...
