Summary: The combination of 1320-nm laser lipolysis with lipoaspiration was observed to improve the appearance and contour of the infrachin neck, doubling the improvement seen with prior lipoaspiration performed by identical technique but without the addition of laser lipolysis. This is a preliminary report as to safety of the use of 1320-nm laser lipolysis. No adverse effects were observed in ...

Fibrosis is the pathological accumulation of extracellular matrix and can occur in all soft tissues. In many organs, including skin, fibrosis also associated with a loss fat or lipid-filled cells. dermal adipose tissue has critical roles which are likely impacted by fibrotic remodeling. Despite identifying numerous dysregulated signaling pathways common to disease, mechanism remains poorly unde...

The mechanisms that control lipolysis in intra-abdominal fat cells from various primate species, the marmoset (Callithrix jacchus), the baboon (Papio papio), and the macaque (Macaca fascicularis), were compared to those of human intraabdominal fat cells. Selective beta 1- or beta 2-adrenoceptor agonists induced lipolysis in all species. Selective beta 3-agonists (BRL 37344, CL 316243, and SR 58...

Adiponectin is an adipokine increasing glucose and fatty acid metabolism and improving insulin sensitivity. The aim of this study was to investigate the role of adiponectin in the regulation of adipocyte lipolysis. Human adipocytes isolated from biopsies obtained during surgical operations from 16 non-obese and 17 obese subjects were incubated with 1) human adiponectin (20 microg/ml) or 2) 0.5 ...

hormone-sensitive lipase, although a role for Ca2+ in some capacity cannot be excluded. The decreased lipolysis cannot be accounted for by a diminished response to cyclic AMP, but the lack of ready reversal of the effects on lipolysis, and the lowering of cell ATP content, suggest that a large part of the effects of both EGTA and ionophore A23 187 on lipolysis may result from damage to fragile ...

Lipolysis is defined as the sequential hydrolysis of triacylglycerol (TAG) stored in cell lipid droplets. For many years, it was believed that hormone-sensitive lipase (HSL) and monoacylglycerol lipase (MGL) were the main enzymes catalyzing lipolysis in the white adipose tissue. Since the discovery of adipose triglyceride lipase (ATGL) in 2004, many studies were performed to investigate and cha...

The ability to sense and respond the external environment capacitates tissue stem cells tailor their activity meet organismal needs. It has long been observed in human that irritation leads acquired hypertrichosis, but mechanism remains unclear. We found that, mice, hair follicle (HFSCs) are activated by with prominent regeneration. is not directly sensed HFSCs themselves niche adipocytes which...

Epidemiological and interventional studies have implicated elevated triglyceride-rich lipoprotein (TGRL) levels as a risk factor for cardiovascular disease and vascular inflammation, though the results have not been entirely consistent. This appears particularly relevant in model systems where the lipolysis occurs in the setting of established inflammation (e.g., in pre-existing atherosclerotic...

The aim of the present study was to gain insight into the signaling pathway used by leptin to stimulate lipolysis. The lipolytic rate of white adipocytes from sex- and age-matched lean (+/+) and fa/fa rats was determined in the absence or presence of leptin together with a number of agents acting at different levels of the signaling cascade. Leptin did not modify FSK-, dbcAMP-, and IBMX-stimula...

OBJECTIVE Elevation of triglyceride-rich lipoproteins (TGRLs) contributes to the risk of atherosclerotic cardiovascular disease. Our work has shown that TGRL lipolysis products in high physiological to pathophysiological concentrations cause endothelial cell injury; however, the mechanisms remain to be delineated. APPROACH AND RESULTS We analyzed the transcriptional signaling networks in arte...
