BACKGROUND Inherited mutations cause approximately 35 percent of cases of dilated cardiomyopathy; however, few genes associated with this disease have been identified. Previously, we located a gene… Expand

Abstract— Sarcoplasmic reticulum (SR) Ca2+ transport proteins, especially ryanodine receptors (RyR) and their accessory protein FKBP12.6, have been implicated as major players in the pathogenesis of… Expand

To examine the role of alterations in myofibrillar function in human dilated cardiomyopathies, we determined isometric tension-calcium relations in permeabilized myocytesized myofibrillar… Expand
Diastolic Compliance of Hypertrophied Ventricle Is Not Acutely Altered by Pharmacologic Agents Influencing Active Processes
Diastolic dysfunction plays an important role in the pathophysiology of human ventricular hypertrophy [1-5]. This dysfunction has two prominent components. Passive structural changes in the… Expand
Sarcomere length dependence of the rate of tension redevelopment and submaximal tension in rat and rabbit skinned skeletal muscle fibres
1 We examined the hypothesis that in skeletal muscle the steep relationship between twitch tension and sarcomere length (SL) within the range 2.30 to 1.85 μm involves SL‐dependent alterations in the… Expand
Rate of tension development in cardiac muscle varies with level of activator calcium.
In skeletal muscle, the rate of transition from weakly bound to force-generating crossbridge states increases as calcium concentration is increased. To examine possible calcium sensitivity of this… Expand
Abnormal Ca 2 Release , but Normal Ryanodine Receptors , in Canine and Human Heart Failure
Sarcoplasmic reticulum (SR) Ca transport proteins, especially ryanodine receptors (RyR) and their accessory protein FKBP12.6, have been implicated as major players in the pathogenesis of heart… Expand
Age-associated changes in function, structure and mitochondrial genetic and enzymatic abnormalities in the Fischer 344 x Brown Norway F(1) hybrid rat heart.
We hypothesized that cardiac aging in the rat involves mitochondrial genetic damage and mitochondrial enzymatic dysfunction of individual cardiomyocytes as has been demonstrated previously only in… Expand
Alterations in left ventricular mechanics, energetics, and contractile reserve in experimental heart failure.
The contributions of changes in primary systolic and diastolic properties, limitations of contractile reserve, and alterations in energy efficiency to the left ventricular dysfunction seen with… Expand
Calcium sensitivity of isometric tension is increased in canine experimental heart failure.
To examine the role of alterations in myofibrillar function in chronic heart failure, we determined isometric tension-pCa relations in permeabilized myocardium from a canine model of dilated… Expand
