Lipoprotein lipase (LPL) hydrolyzes triacylglycerol (TG) of TG-rich lipoproteins. We investigated the effects of sphingomyelin (SM) and cholesterol (Chol) on the lipolysis of lipid emulsions by LPL using human apolipoprotein C-II (apoC-II) or plasma as an activator. Kinetic studies of the lipolysis rates clearly demonstrated that the primary effect of the activator on the LPL reaction was not t...
Animal/cell investigations indicate that there is a decreased adipose tissue mass resulting from skeletal muscle (SkM) IL-15 secretion (e.g., SkM-blood-adipose tissue axis). IL-15 could regulate fat mass accumulation in obesity via lipolysis, although this has not been investigated in humans. Therefore, the purpose was to examine whether SkM and/or subcutaneous adipose tissue (SCAT) IL-15 conce...
Internal lipoplasty (iLAL) represents an evolving procedure that depends on delivery of sufficient and controlled thermal energy for lipolysis and collagen denaturation. Of the two outcomes, the particular advantage of iLAL may exist in its capability to selectively denature, remodel, and contract collagen and elastin fibers for eventual skin contraction. Despite the practice of sound laser pri...
The aim of this experiment was to evaluate the direct effect of genistein, daidzein and zearalenone on basal and hormone-induced lipogenesis and lipolysis in isolated rat adipocytes. In lipogenesis, daidzein and zearalenone were used at concentrations of 0.01, 0.1 and 1 mmol x L(-1) and genistein at concentrations of 0.01, 0.3, 0.6 and 1 mmol x L(-1). In lipolysis, concentrations of tested comp...
Since insulin is known to stimulate intracellular hydrogen peroxide production in rat epididymal fat cells, the effects of exogenous hydrogen peroxide on rates of basal and hormone-stimulated lipolysis were investigated in a perifusion system. H2O2 (60 microM) caused a weak and transient stimulation of basal lipolysis that did not interfere with subsequent activation of lipolysis by hormones. M...
Lipases are extensively used in the dairy industry for the hydrolysis of milk fat. The dairy industry uses lipases to modify the fatty acid chain lengths, to enhance the flavours of various cheeses. Current applications also include the acceleration of cheese ripening and the lipolysis of butter, fat and cream. The free fatty acids generated by the action of lipases on milk fat endow many dairy...
BACKGROUND/AIMS In fat cells of obese humans, basal lipolysis is increased but catecholamine-stimulated lipolysis is blunted. This is linked to decreased expression of hormone-sensitive lipase (HSL). Upon stimulation by cAMP, HSL is phosphorylated at several serine residues (P-Ser(552), P-Ser(649) and P-Ser(650)) leading to enzymatic activation. In contrast, P-Ser(554) prevents phosphorylation ...
In obesity, high levels of tumor necrosis factor α (TNFα) stimulate lipolysis in adipocytes, leading to hyperlipidemia and insulin resistance. Thiazolidinediones (TZDs), the insulin-sensitizing drugs, antagonize TNFα-induced lipolysis in adipocytes, thereby increasing insulin sensitivity in diabetes patients. The cellular target of TZDs is peroxisome proliferator-activated receptor γ (PPARγ), a...
