OBJECTIVES We evaluated ankyrin repeat domain 1 (ANKRD1), the gene encoding cardiac ankyrin repeat protein (CARP), as a novel candidate gene for dilated cardiomyopathy (DCM) through mutation analysis of a cohort of familial or idiopathic DCM patients, based on the hypothesis that inherited dysfunction of mechanical stretch-based signaling is present in a(More)
OBJECTIVES The purpose of this study was to explore a novel disease gene for hypertrophic cardiomyopathy (HCM) and to evaluate functional alterations caused by mutations. BACKGROUND Mutations in genes encoding myofilaments or Z-disc proteins of the cardiac sarcomere cause HCM, but the disease-causing mutations can be found in one-half of the patients,(More)
Circadian disruption has deleterious effects on metabolism. Global deletion of Bmal1, a core clock gene, results in β-cell dysfunction and diabetes. However, it is unknown if this is due to loss of cell-autonomous function of Bmal1 in β cells. To address this, we generated mice with β-cell clock disruption by deleting Bmal1 in β cells (β-Bmal1(-/-)).(More)
OBJECTIVES This study sought to evaluate the outcome and prevalence of viral endomyocardial infection after cardiac transplantation. BACKGROUND Viral myocardial infection causes heart failure, but its role after cardiac transplantation is unclear. We hypothesized that viral infection of the cardiac allograft reduces graft survival. METHODS Between June(More)
BACKGROUND Detection of viral genome in rejecting cardiac transplant patients has been reported, with coxsackievirus and adenovirus causing premature graft failure. Recently, parvovirus B19 (PVB19) genome in myocardial samples has been increasingly reported, but its role in cardiac pathology and effect on transplant graft survival are unknown. The(More)
Circadian disruption is the bane of modern existence and its deleterious effects on health; in particular, diabetes and metabolic syndrome have been well recognized in shift workers. Recent human studies strongly implicate a 'dose-dependent' relationship between circadian disruption and diabetes. Genetic and environmental disruption of the circadian clock(More)
BACKGROUND Obesity and cachexia are risk factors for adverse outcomes in adult transplant patients. However, little is known about the effects of body mass index (BMI) on outcomes in pediatric heart transplant patients. METHODS Patients > 2 years of age undergoing heart transplantation from 1985 to 2004 at our institution were included in this study. BMI(More)
A breakdown in self-tolerance underlies autoimmune destruction of β-cells and type 1 diabetes. A cure by restoring β-cell mass is limited by the availability of transplantable β-cells and the need for chronic immunosuppression. Evidence indicates that inhibiting costimulation through the PD-1/PD-L1 pathway is central to immune tolerance. We therefore tested(More)
BACKGROUND Complete atrioventricular canal defects (CAVC) are a common heart defect, but few epidemiologic studies have evaluated non-syndromic CAVC. Risk factors for non-syndromic CAVC have not been well established. METHODS To assess the relationship between risk for non-syndromic CAVC in offspring and several sociodemographic and reproductive parental(More)
BACKGROUND Viral genome in cardiac allograft has been associated with early graft loss in children who have undergone cardiac transplant from unknown mechanisms. METHODS This study is a retrospective review of children who have undergone cardiac transplant at a single institution from 1/2004 to 5/2008. Patients underwent cardiac catheterisations with(More)
