A novel gene encoding a 25-kDa neuronal-specific protein, here named 'NP25', has been isolated as a cDNA clone from rat brain. The sequence of the NP25 cDNA reveals a single open reading frame that encodes a primary translation product of 206 amino acids. A search of the protein sequence databank indicates that NP25 is significantly homologous with three(More)
BACKGROUND The existence of circulating endothelial progenitor cells (CEPCs) has previously been documented. These cells can be mobilized by cytokines and are recruited to sites of injury, where they may participate in tissue repair. In the present study, we examined the hypothesis that mobilization of CEPCs by exogenous granulocyte-colony stimulating(More)
BACKGROUND Circulating endothelial progenitor cells (EPCs) have been reported previously. In this study, we examined the hypothesis that overexpression of vasculoprotective gene endothelial nitric oxide synthase (eNOS) and heme oxygenase-1 (HO-1) in EPCs enhances their ability to inhibit neointimal hyperplasia. METHODS AND RESULTS EPCs were isolated from(More)
Recent molecular studies have suggested that viral myocarditis frequently underlies human congestive cardiomyopathy; however, only moderately sensitive and specific techniques were used. Polymerase chain reaction (PCR) gene amplification is a sensitive, specific technique ideally suited for the diagnosis of viral disease in small tissue samples where low(More)
BACKGROUND The regulation of extracellular calcium concentration by parathyroid hormone is mediated by a calcium-sensing, G-protein-coupled cell-surface receptor (CASR). Mutations of the CASR gene alter the set-point for extracellular ionised calcium [Ca2+]o and cause familial hypercalcaemia or hypocalcaemia. The CASR missense polymorphism, A986S, is common(More)
Considerable neuroanatomical and pharmacological evidence suggests that preproenkephalin A-derived peptides, particularly methionine-enkephalin, are involved in regulation of the cardiovascular system in both physiological and pathological states. In this study, we used a rat preproenkephalin A complementary DNA to determine whether proenkephalin A-derived(More)
BACKGROUND Endothelin-1 (ET-1) may function as an aldosterone secretagogue and, in turn, aldosterone can upregulate ET-1 expression. Hence, the existence of a feedforward loop involving ETs and aldosterone has been speculated in primary aldosteronism (PA). In the present study, we sought to examine ET-1 secretion from the adrenal glands in patients with PA.(More)
It has been suspected that the cause of malignant hyperthermia (MH) is an abnormality in the sarcoplasmic reticulum of skeletal muscle. We isolated the sarcoplasmic reticulum from malignant hyperthermia-susceptible (MHS) patients and controls and analysed the protein composition with sodium dodecyl sulfate polyacrylamide gel electrophoresis. There were no(More)
Non-histone chromatin proteins (NHCP) were isolated from skeletal muscle, left ventricle and liver of swine susceptible to malignant hyperthermia and from controls. These proteins were extracted with phenol buffers and fractionated by polyacrylamide gel electrophoresis. Isoelectrofocusing gel electrophoresis revealed quantitative differences in NHCP from(More)
Muscular subaortic stenosis (MSS) is a genetically determined cardiomyopathy, whereas right ventricular infundibular hypertrophy (IH) apparently is an acquired condition. Since genetic expression in eukaryotic cells may be regulated primarily by DNA-associated proteins, we isolated and characterized the proteins of heart nuclei from nine patients with MSS,(More)
