Text-mined interactions from Literome

Souza et al., J Biol Chem 2002 : Activation of cyclic AMP dependent protein kinase (PKA) results in the phosphorylation of Peri A and hormone-sensitive lipase (HSL) , the predominant lipase in adipocytes, with concurrent stimulation of adipocyte lipolysis
He et al., Biochim Biophys Acta 2006 : Lipolysis is primarily regulated by protein kinase A (PKA) , which phosphorylates perilipin and hormone-sensitive lipase (HSL), and causes translocation of HSL from cytosol to lipid droplets in adipocytes
Miyoshi et al., J Biol Chem 2006 : Using adipocytes retrovirally engineered from murine embryonic fibroblasts of perilipin null mice ( Peri-/- MEF ), we demonstrate by cell fractionation and confocal microscopy that up to 50 % of cellular HSL is LD-associated in the basal state and that PKA stimulated HSL translocation is fully supported by adenoviral expression of a mutant perilipin lacking all six PKA sites ( Peri Adelta1-6 ) ... PKA stimulated HSL translocation was confirmed in differentiated brown adipocytes from perilipin null mice expressing an adipose-specific Peri Adelta1-6 transgene ... Thus, PKA induced HSL translocation was independent of perilipin phosphorylation
Granneman et al., J Biol Chem 2007 : Double label immunofluorescence analysis of 3T3-L1 adipocytes indicated that PKA activation increases the translocation of hormonesensitive lipase (HSL) to perilipin A (Plin) containing droplets and increases the colocalization of adipose tissue triglyceride lipase ( Atgl ) with its coactivator, Abhd5
Krintel et al., FEBS J 2009 : The exact molecular events of PKA mediated activation of HSL in vitro are yet to be determined, but increases in both Vmax and S0.5 seem to be involved, as recently shown for human HSL
Djouder et al., EMBO J 2010 : TAG resynthesis is associated with high-energy consumption, which when inordinate, leads to increased AMPK activity that acts to restrain hydrolysis of TAGs by inhibiting PKA mediated activation of HSL
Lee et al., Am J Physiol Endocrinol Metab 2012 (Insulin Resistance) : Cotreatment with DEX blocked TNF induction of basal lipolysis and insulin resistance by antagonizing TNF stimulation of PKA mediated phosphorylation of hormone-sensitive lipase (HSL) at Ser ( 563 ) and Ser ( 660 ) and perilipin
Mulder et al., Diabetes 1999 : Because HSL in adipocytes is activated by cAMP dependent protein kinase (PKA) , PKA regulated triglyceride hydrolysis in beta-cells may participate in the regulation of insulin secretion, possibly by providing a lipid derived signal, e.g., long-chain acyl-CoA and diacylglycerol
