Inheritance of the epsilon4 allele of the apolipoprotein E gene (APOE4) is a major risk factor for the development of Alzheimer's disease (AD). Although the association between APOE4 and AD is well documented, the mechanism by which apolipoprotein E exerts an isoform-specific effect on neurons in disease is unknown. In this report, we demonstrate that apoE4(More)
BACKGROUND Because no study has documented the angiogenic properties of hepatocyte growth factor (HGF) in a diabetes model, we examined the feasibility of gene therapy using HGF to treat peripheral arterial disease in diabetes. METHODS AND RESULTS Because intramuscular injection of luciferase plasmid by the hemagglutinating virus of Japan (HVJ)-liposome(More)
BACKGROUND AND PURPOSE A disordered proliferative process in the vascular wall is thought to underlie the pathogenesis of restenosis after percutaneous transluminal angioplasty and carotid endarterectomy. A growth inhibitory property of overexpressed prostacyclin (PGI2) synthase (PGIS) was recently implicated in the pathological proliferation of vascular(More)
AIM To indicate the extent of lipid peroxidation induced by oxidative stress, by measuring aldehyde end products in biological samples. METHODS A highly specific gas chromatography and mass spectrometry (GC/MS) method was used to measure plasma concentrations of aliphatic aldehydes within the first week of life in 13 premature infants who subsequently(More)
Alzheimer's disease (AD) is the most common cause of dementia (32). Although the majority of cases of AD are sporadic, the most consistent risk factor detected in several epidemiological studies has been a positive family history of the disease (14,21). In addition, many large pedigrees have been described in which AD appears to be inherited as an autosomal(More)
Hepatocyte growth factor (HGF) exclusively stimulates the growth of endothelial cells without replication of vascular smooth muscle cells and acts as a survival factor against endothelial cell death. Therefore we hypothesized that a decrease in local vascular HGF might be related to the pathogenesis of peripheral arterial disease. We initially evaluated(More)
Glucocorticoids reportedly induce insulin resistance. In this study, we investigated the mechanism of glucocorticoid-induced insulin resistance using 3T3-L1 adipocytes in which treatment with dexamethasone has been shown to impair the insulin-induced increase in glucose uptake. In 3T3-L1 adipocytes treated with dexamethasone, the GLUT1 protein expression(More)
BACKGROUND Because hepatocyte growth factor (HGF) prevented and/or regressed fibrosis in liver and pulmonary injury models, HGF may play an important role in the pathogenesis of fibrotic cardiovascular disease. Because angiotensin (Ang) II significantly decreased local HGF production, we performed (1) in vitro experiments using fibroblasts and (2)(More)
Upon binding to the cAMP-response element of a gene's promoter, the transcription factor known as cAMP-response element-binding protein (CREB) facilitates transcription of many different neuronal genes including those involved with synaptic function. Based on our previous reports of gene structure (GenBank accession number AF029701 ), we now demonstrate(More)
BACKGROUND The Framingham Study recently revealed that the homozygous deletion polymorphism of the angiotensin-converting enzyme gene (ACE DD) is associated with increased risk for essential hypertension in a male-specific manner. However, this association has not been confirmed in races other than whites. METHODS AND RESULTS Using a large number of(More)
