(Submitter supplied) G protein-coupled receptor kinase 2 (GRK2) has emerged as a key regulator of cardiac function and myocardial structure. Cardiac GRK2 is increased in heart failure and ischemia in humans, whereas genetic inhibition of GRK2 is cardioprotective in animal models of these pathologies. However, the mechanistic basis underlying these effects are not fully understood. We have used adult GRK2 hemizygous mice (GRK2+/-) as a model to assess the effects of a sustained systemic inhibition of GRK2 in heart tissue with age. more...

(Submitter supplied) In order to study the heart disorder that the long term, high energy diet caused, Bama miniature pigs were fed a high-fat, high-sucrose diet for 23 months. These pigs developed symptoms of metabolic syndrome and showed cardiac steatosis and hypertrophy with a greatly increased heart weight (1.82-fold, P<0.05) and heart volume (1.60-fold, P<0.05) compared with the control pigs. To understand the molecular mechanisms of cardiac steatosis and hypertrophy, nine pig heart cRNA samples were hybridized to porcine GeneChips.

(Submitter supplied) The fatty acid synthase (FASN) is the major fat synthesizing enzyme. FASN is an indispensable enzyme because mice with genetic deletion of Fasn are not viable. Apart from its physiological function, previous studies indicated that FASN could also exert a pathophysiological role, in the heart, because patients with heart failure showed up-reguation of FASN. To investigate the in vivo function of FASN up-regulation in the heart, we generated mice with myocardium-specific expression of FASN under control of the alpha-MHC promoter. more...

(Submitter supplied) The anti-diabetic drug and agonist of the peroxisome proliferator-activated receptor gamma (Pparg), rosiglitazone, was recently withdrawn in many countries because the drug use was associated with an increased risk of heart failure. To investigate underlying pathomechanisms, we chose 6-month-old apolipoprotein E (apoE)-deficient mice, which are prone to atherosclerosis and insulin resistance, and thereby mimic the risk profile of patients with cardiovascular disease. more...

(Submitter supplied) The ubiquitously expressed G-protein-coupled receptor kinase 2 (GRK2, ADRBK1) is an indispensable kinase involved in growth, differentiation and development. Exaggerated GRK2 activity plays a major pathophysiological role in the development of cardiovascular diseases such as heart failure and hypertension. GRK2 exerts its functions by kinase-dependent and kinase-independent effects. To assess the differential impact of GRK2 on cellular signalling we established HEK cell clones with over-expression of comparable protein levels of GRK2 or the kinase-deficient GRK2-K220R mutant, respectively. more...

(Submitter supplied) The Raf kinase inhibitor protein (RKIP) is a dual inhibitor of the Raf kinase and the G-protein-coupled receptor kinase 2 (GRK2). GRK2 is an indispensable kinase, which exerts a major role in the pathogenesis of heart failure, and inhibition of GRK2 is cardioprotective in experimental models of heart failure. To investigate the cardiac function of RKIP as GRK2 inhibitor, we generated transgenic mice with myocardium-specific expression of RKIP under control of the alpha-MHC promoter. more...

Analysis of HEK cells expressing dominant-negative GRK2-K220R. HEK cells were cultured, or expanded in NOD.Scid mice, or re-cultured after NOD.Scid expansion. GRK2-K220R enhances growth of NOD.Scid HEK cells but not cultured HEK cells. Results provide insight into basis of growth control by GRK2.

(Submitter supplied) Insulin resistance increases patient’s risk of developing type 2 diabetes (T2D), nonalcoholic steatohepatitis (NASH) and a host of other comorbidities including cardiovascular disease and cancer. At the molecular level, insulin exerts its function through the insulin receptor (IR), a transmembrane receptor tyrosine kinase. Data from human genetic studies have shown that Grb14 functions as a negative modulator of IR activity, and germline Grb14-knockout (KO) mice have improved insulin signaling in liver and muscle tissues. more...

(Submitter supplied) The raf kinase inhibitor protein, RKIP, is up-regulated on cadiac biopsy specimens of heart failure patients. To investigate the in vivo role of an increased cardiac content of RKIP, we generated transgenic mice with myocardium-specific expression of RKIP (PEBP1; phosphatidylethanolamine binding protein 1) under control of the alpha-MHC promoter in B6 (C57BL/6J) background. Because RKIP is a dual-specific GRK2 and Raf kinase inhibitor, RKIP-transgenic mice were compared to transgenic mice with myocardium-specific expression of the GRK2 inhibitor, GRK2-K220R, which is a kinase-inactive GRK2 (ADRBK1) mutant with dominant-negative function. more...
