Human fat cell lipolysis was, until recently, thought to be mediated exclusively by a cAMP-dependent protein kinase (PKA)-regulated pathway under the control of catecholamines and insulin. We have shown that atrial- and B-type natriuretic peptides (ANP and BNP respectively) stimulate lipolysis in human fat cells through a cGMP-dependent protein kinase (PKG)(More)
Eight pairs of obese female monozygotic twins were subjected to a 4-week, very-low-calorie diet (VLCD) that induced a decrease in mean body mass index from 32.9 +/- 1.1 to 29.7 +/- 1.1 kg/m2. Infusion of the beta-adrenergic agonist, isoproterenol, induced an increase in plasma levels of nonesterified fatty acids and glycerol that was more pronounced during(More)
Involvement of sympathetic nervous system and natriuretic peptides in the control of exercise-induced lipid mobilization was compared in overweight and lean men. Lipid mobilization was determined using local microdialysis during exercise. Subjects performed 35-min exercise bouts at 60% of their maximal oxygen consumption under placebo or after oral(More)
