B-type natriuretic peptide (BNP) is a hormone released from cardiomyocytes in response to cell stretching and elevated in heart failure. Recent observations indicate a distinct connection between chronic heart failure and diabetes mellitus. This study investigated the role of BNP on glucose metabolism. Ten healthy volunteers (25 ± 1 years; BMI 23 ± 1 kg/m2;(More)
CONTEXT Osteopontin (OPN) is a multifunctional protein involved in bone metabolism, cardiovascular disease, diabetes, and obesity. OPN levels are elevated in the plasma and adipose tissue of obese subjects, and are decreased with diet-induced weight loss. OBJECTIVE We investigated the effect of bariatric surgery on plasma OPN concentrations in morbidly(More)
Oxytocin is a hormone and neurotransmitter found to have anti-inflammatory functions in rodents. Here we used experimental bacterial endotoxinemia to examine the role of exogenous oxytocin administration on innate immune responses in humans. Ten healthy men received, in a randomized, placebo-controlled, crossover design, placebo, oxytocin, LPS, and LPS +(More)
CONTEXT Sonic hedgehog (Shh) belongs to a family of signaling proteins involved in development and has been recently implicated in cancer. Shh signaling is active in the corticotrophs of the adult pituitary gland, where it cross-talks with the CRH pathway and regulates ACTH secretion. Because developmental pathways are involved in pituitary tumorigenesis,(More)
BACKGROUND Growth differentiation factor-15 (GDF-15) is a stress-responsive cytokine linked to obesity comorbidities such as cardiovascular disease, inflammation, and cancer. GDF-15 also has adipokine properties and recently emerged as a prognostic biomarker for cardiovascular events. METHODS We evaluated the relationship of plasma GDF-15 concentrations(More)
Sonic hedgehog (Shh) is a signaling protein that binds to Patched and mediates its effects through Gli transcription factors. Shh is important in regulating survival and growth in both the embryo and the adult. It is known to be involved in pituitary development, but its role in the adult pituitary has not been investigated. Here, we show Shh and Gli1(More)
AIMS We aimed to evaluate the association of the nutritional status by using the nutritional risk index (NRI) with metabolic and inflammatory biomarkers, and appetite-regulatory hormones in a cohort of stable patients with heart failure (HF), and to analyse its prognostic value. METHODS AND RESULTS In this prospective observational cohort study, we(More)
Adrenomedullin (ADM) is a vasoactive peptide found to be related to obesity and its comorbidities: type 2 diabetes, hypertension, atherosclerosis, and coronary heart disease. ADM is increased both in plasma and in adipose tissue of obese individuals when compared to lean subjects and is considered as a member of the adipokine family. We determined plasma(More)
CONTEXT Ghrelin is a gut hormone with a highly preserved biological activity, which seems not to be restricted to the regulation of food intake, body composition, and growth. Continuous research is unraveling new properties of ghrelin, among others cardiovascular and antiinflammatory activities. Ghrelin is recently implicated in the host response to(More)
