Active autophagy but not lipophagy in macrophages with defective lipolysis
During autophagy, autophagosomes fuse with lysosomes to degrade damaged organelles and misfolded proteins. Breakdown products are released into the cytosol and contribute to energy and metabolic building block supply, especially during starvation. Lipophagy has been defined as the autophagy-mediated degradation of lipid droplets (LDs) by lysosomal acid lipase. Adipose triglyceride lipase (ATGL)...
متن کاملHormone-stimulated lipolysis in cardiac myocytes.
Type L hormone-sensitive lipase (HSL) activity was increased approx. 35% above control in cardiac myocytes incubated for 15 min with 5 nM-adrenaline. Concomitantly. adrenaline-stimulated myocytes had a lower triacylglycerol content, released more non-esterified fatty acid and had a higher intracellular concentration of cyclic AMP than did myocytes incubated without hormone. The lipase activity ...
متن کاملEffect of β2‐adrenergic receptor polymorphisms on epinephrine and exercise‐stimulated lipolysis in humans
The β2-adrenergic system is an important regulator of human adipose tissue lipolysis. Polymorphisms that result in amino acid substitutions in the β2-adrenergic receptor have been reported to alter lipolysis. We hypothesized that variations in the amino acid at position 16 of the β2-adrenergic receptor would result in different lipolytic responses to intravenous epinephrine and exercise. 17 vol...
متن کاملLipolysis
Successful adaptation to starvation in mammals depends heavily on the regulated mobilization of fatty acids from triacylglycerols stored in adipose tissue. Although it has long been recognized that cyclic AMP represents the critical second messenger and hormone-sensitive lipase (HSL)**Abbreviations used in this paper: ADRP, adipocyte differentiation-related protein; HSL, hormone-sensitive lipas...
متن کاملEffect of purines on epinephrine-induced lipolysis in adipose tissue.
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...
