BACKGROUND The epicardial border zone (EBZ) of surviving myocytes in the healing, 4- to 5-day-old canine infarct is an arrhythmogenic substrate characterized by both structural and functional remodeling of Cx43. Unknown is whether the remodeling of gap junction conductance is heterogeneous in the EBZ like that of sarcolemmal ion channel remodeling and how(More)
PURPOSE Provide a reproducible method for culturing confluent monolayers of hfRPE cells that exhibit morphology, physiology, polarity, and protein expression patterns similar to native tissue. METHODS Human fetal eyes were dissected on arrival, and RPE cell sheets were mechanically separated from the choroid and cultured in a specifically designed medium(More)
Retinitis pigmentosa is one of the main causes of blindness throughout the world and its pathogenesis remains unclear. In this study, patch-clamp recording was performed from ganglion cells in retinal dystrophic Royal College of Surgeons rats and normal rats during development. The three discharge patterns of action potential in ganglion cells of Royal(More)
Telomeres are protective chromosomal structures that play a key role in preserving genomic stability. Epidemiologic studies have shown that the abnormal telomere length in leukocytes is associated with some mental disorders and age-related diseases. However, the association between leukocyte telomere length and autism has not been investigated. Here we(More)
OBJECTIVE Current evidence suggests high serum uric acid may increase the risk of type 2 diabetes, but the association is still uncertain. The aim of the study was to evaluate the association between serum uric acid and future risk of type 2 diabetes by conducting a meta-analysis of prospective cohort studies. DESIGN AND METHODS We conducted a systematic(More)
Adrenocorticotropic hormone (ACTH) has a renoprotective effect in chronic kidney disease; however, its effect on acute kidney injury (AKI) remains unknown. In a rat model of tumor necrosis factor (TNF)-induced AKI, we found that ACTH gel prevented kidney injury, corrected acute renal dysfunction, and improved survival. Morphologically, ACTH gel ameliorated(More)
Miller SS. IFN␥ regulates retinal pigment epithelial fluid transport. experiments show that IFN␥ receptors are mainly localized to the basolateral membrane of human retinal pigment epithelium (RPE). Activation of these receptors in primary cultures of human fetal RPE inhibited cell proliferation and migration, decreased RPE mitochon-drial membrane(More)
Notch signaling plays a critical role during development by directing the binary cell fate decision between progenitors and differentiated cells. Previous studies have shown sustained Notch activation in cartilage leads to chondrodysplasia. Genetic evidence indicates that Notch regulates limb bud mesenchymal stem cell differentiation into chondrocytes via(More)
Proteinuria is an independent risk factor for end-stage renal disease (ESRD) (Shankland, 2006). Recent studies highlighted the mechanisms of podocyte injury and implications for potential treatment strategies in proteinuric kidney diseases (Zhang et al., 2012). Reactive oxygen species (ROS) are cellular signals which are closely associated with the(More)
Podocytes have a complex cellular architecture with interdigitating processes maintained by a precise organization of actin filaments. The actin-based foot processes of podocytes and the interposed slit diaphragm form the final barrier to proteinuria. The function of podocytes is largely based on the maintenance of the normal foot process structure with(More)
