Prostaglandin E(2) (PGE(2)) stimulated leptin release over a 24-h incubation of mouse adipose tissue in primary culture. The maximal stimulation of leptin release was seen with 100 nm PGE(2). The role of endogenous eicosanoids in the regulation of lipolysis and leptin formation was examined in the presence of NS-398, a selective cyclooxygenase-2 inhibitor. NS-398 at a concentration of 5 microm ...
The insect steroid hormone 20-hydroxyecdysone (20E) acts through a specific nuclear receptor complex, ecdysone receptor (EcR) and ultraspiracle (USP). EcR and USP are FXR/LXR and RXR orthologs, respectively, which play critical roles in the regulation of lipid metabolism in mammals. Lipid concentration in Bombyx hemolymph and lipase activity in fat body peaked during molting and pupation, sugge...
The present study was carried out in two phases. In phase one optimization for the stage, form and rate of addition cardamom to control lipolysis out. prepared khoa packed polypropylene (PP) containers stored at 7±1°C and/or 15±1°C. During storage, samples were evaluated an interval 48 hours acceptability by sensory analysis monitored lipolytic changes terms free fatty acids (FFA) content. Base...
In adipocytes the hydrolysis of TAG to produce fatty acids and glycerol under fasting conditions or times of elevated energy demands is tightly regulated by neuroendocrine signals, resulting in the activation of lipolytic enzymes. Among the classic regulators of lipolysis, adrenergic stimulation and the insulin-mediated control of lipid mobilisation are the best known. Initially, hormone-sensit...
Fatty acids (FAs) activate and fuel UCP1-mediated non-shivering thermogenesis (NST) in brown adipose tissue (BAT). Release of FAs from intracellular fat stores by adipose triglyceride lipase (ATGL) is considered a key step in NST. Accordingly, the severe cold intolerance of global ATGL knockout (AKO) mice has been attributed to defective BAT lipolysis. Here we show that this conclusion is incor...
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...
Although laser lipolysis has been described as a “lunchtime treatment”, it is nevertheless classified as a surgical procedure associated with certain risks due to surgical incisions and the use of anesthetics, as well as with subsequently reduced skin firmness and lack of skin ability to conform to the reduced body size. We aimed to develop a safe and effective alternative to address both exces...
The current literature on lipolysis in murine primary adipocytes is rife with experiments performed under conditions not optimized for reproducible and reliable results. Here, we present conditions for optimizing the measurement of lipolysis in murine adipocytes. We demonstrate that adenosine management is of paramount importance in evaluating the lipolytic response under basal and stimulated c...
The purine bases hypoxanthine, xanthine, guanine, and purine markedly inhibit epinephrine-induced lipolysis in rat adipose tissue, an action previously ascribed only to nucleosides, nucleotides, and nucleic acids. The inhibition by purines and purine conjugates is associated with increased destruction of epinephrine. Allopurinol, an inhibitor of xanthine oxidase, prevents the degradation of epi...
Catecholamine-stimulated lipolysis occurs by activating adenylate cyclase and raising cAMP levels, thereby increasing protein kinase A (PKA) activity. This results in phosphorylation and modulated activity of several key lipolytic proteins. Adipose triglyceride lipase (ATGL) is the primary lipase for the initial step in triacylglycerol hydrolysis, and ATGL activity is increased during stimulate...
