Cytosolic lipolysis is induced during heart failure, and adipose triglyceride lipase (ATGL) regulates cardiac function. Kintscher et al. discuss how the deletion or inhibition of adipose tissue ATGL improves cardiac function in pre-clinical heart failure models. Pharmacological inhibition of adipose tissue ATGL may provide a therapeutic intervention direction for heart failure.

2015-8-1 · Lipolysis and lipases in white adipose tissue - An update. 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.
Regulation of Lipolysis in Adipocytes
INTRODUCTION. White adipose tissue (WAT) triacylglycerol (TAG) is the major energy reserve in higher eukaryotes. This lipid pool is in a constant state of flux, resulting from a largely futile cycle of lipolysis and re-esterification ().During times of energy deprivation, WAT undergoes a shift toward greater net rates of lipolysis, which can be defined as the hydrolysis of TAG to generate ...
The Molecular Brakes of Adipose Tissue Lipolysis
Adipose tissue, the body’s largest reservoir of energy and a major source of metabolic fuel, exerts a buffering function for fluctuations in nutrient availability. This functional plasticity ranges from energy storage in the form of triglycerides during periods of excess energy intake to energy mobilization via lipolysis in the form of free ...
Importance of TNFα and neutral lipases in human adipose ...
Catecholamines and natriuretic peptides stimulate human adipocyte lipolysis through an increase in cAMP and cGMP levels, resulting in phosphorylation and activation of hormone-sensitive lipase. A defect in hormone-sensitive lipase expression might contribute to the resistance to catecholamine-induced lipolysis observed in obesity. The respective roles and regulation of …
Fat Mobilization in Adipose Tissue Is Promoted by Adipose ...
2004-11-19 · Mobilization of fatty acids from triglyceride stores in adipose tissue requires lipolytic enzymes. Dysfunctional lipolysis affects energy homeostasis and may contribute to the pathogenesis of obesity and insulin resistance. Until now, hormone-sensitive lipase (HSL) was the only enzyme known to hydrolyze triglycerides in mammalian adipose tissue.

The understanding of the cellular factors regulating triglyceride hydrolysis and the metabolic function of lipases has considerably expanded in the last few years, revealing an …
Regulation of adipose tissue lipolysis revisited - PubAg
Regulation of adipose tissue lipolysis revisited. Human obesity and its complications are an increasing burden in developed and underdeveloped countries. Adipose tissue mass and the mechanisms that control it are central to elucidating the aetiology of obesity and insulin resistance. Over the past 15 years tremendous progress has been made in ...

2005-11-1 · The rate-limiting role of HSL in adipose tissue lipolysis has been challenged by the data from HSL knockout mice (12–15). Catecholamine-induced lipolysis is abrogated, but residual basal lipolysis is observed in adipocytes from HSL-null mice. These data suggest the existence of non-HSL lipases in adipose tissue.
