Splanchnic lipolysis in human obesity.
Elevated FFA concentrations have been shown to reproduce some of the metabolic abnormalities of obesity. It has been hypothesized that visceral adipose tissue lipolysis releases excess FFAs into the portal vein, exposing the liver to higher FFA concentrations. We used isotope dilution/hepatic vein catheterization techniques to examine whether intra-abdominal fat contributes a greater portion of...
متن کاملChanges in catecholamine-induced lipolysis in isolated human fat cells during the first year of life.
Catecholamine-induced lipolysis in isolated human adipocytes during the first year of life was investigated. During this period fat cell size increased markedly. Basal and catecholamine-induced glycerol release were positively correlated with age when lipolysis was expressed per cell. However, when lipolysis was expressed per unit of cell surface area (micrometer squared), this correlation was ...
متن کاملCatecholamine-induced lipolysis causes mTOR complex dissociation and inhibits glucose uptake in adipocytes.
Anabolic and catabolic signaling oppose one another in adipose tissue to maintain cellular and organismal homeostasis, but these pathways are often dysregulated in metabolic disorders. Although it has long been established that stimulation of the β-adrenergic receptor inhibits insulin-stimulated glucose uptake in adipocytes, the mechanism has remained unclear. Here we report that β-adrenergic-m...
متن کاملCatecholamine and insulin control of lipolysis in subcutaneous adipose tissue during long-term diet-induced weight loss in obese women.
The aim of this study was to investigate the evolution of the adrenergic and insulin-mediated regulation of lipolysis during different phases of a 6-mo dietary intervention. Eight obese women underwent a 6-mo dietary intervention consisting of a 1-mo very low-calorie diet (VLCD) followed by a 2-mo low-calorie diet (LCD) and 3-mo weight maintenance (WM) diet. At each phase of the dietary interve...
متن کامل[Catecholamine-induced myocarditis in pheochromocytoma].
Pheochromocytoma is a rare tumor, usually benign, potentially lethal in case of crisis with acute release of catecholamines. The heart is a target and the clinical presentation can mimic various cardiac conditions, thus rendering diagnosis elusive. Cardiac magnetic resonance is a valuable non-invasive diagnostic tool for the evaluation of cardiomyopathies; it allows the identification of catech...
