Helper virus-free herpes simplex virus (HSV-1) plasmid vectors are attractive for neural gene transfer, but a promoter that supports neuronal-specific, long-term expression is required. Although expression from many promoters is unstable, a 6.8-kb, but not a 766-bp, fragment of the tyrosine hydroxylase (TH) promoter supports long-term expression. Thus, 5'(More)
BACKGROUND AND OBJECTIVE The drug transporter MDR1 and the drug metabolizing enzyme CYP3A are the two major biological factors determining the pharmacokinetics of many drugs. The functional MDR1 single nucleotide polymorphisms (SNPs) and a prevalent CYP3A5 SNP show marked interethnic variation among Orientals, Caucasians and Africans. In this study, we(More)
Herpes simplex virus type 1 (HSV-1) plasmid vectors have a number of attractive features for gene transfer into neurons. In particular, the large size of the HSV-1 genome suggests that HSV-1 vectors might be designed to co-express multiple genes. Here, we report a general strategy for constructing large HSV-1 plasmid vectors that co-express multiple genes.(More)
BACKGROUND AND OBJECTIVE Tacrolimus, an immunosuppressant widely used after liver transplantation, is characterized by a large inter-individual variability in its pharmacokinetics. The aim of this study was to perform population pharmacokinetic analysis of oral tacrolimus in liver transplant recipients and clarify the potential role of CYP3A5, MDR1 and(More)
Herpes simplex virus (HSV-1) gene expression is hypothesized to shut off promoters in HSV-1 vectors, but in a helper virus-free HSV-1 vector system, a number of promoters support only short-term expression. Thus, recombinant gene expression remains short-term in the absence of approximately 99% of the HSV-1 genome. To resolve this paradox, we hypothesized(More)
A helper virus-free herpes simplex virus type 1 (HSV-1) plasmid vector system has potential for both gene therapy and physiological studies, but relatively low titers have complicated use of this system. In this article, the packaging efficiency was improved by optimizing the packaging protocol and by adding noninfectious HSV-1-related particles, i.e.,(More)
This paper reports an interesting case of myelodysplastic syndrome (MDS), whose bone marrow karyotype at diagnosis was 46, XY, t(16;17) (q12;q25). Fourteen months later, the disease transformed into erythroleukemia, and several correlative clones with hyperdiploid appeared at the same time. Thus, we consider that detecting karyotypic evolution may help(More)
WHAT IS KNOWN AND OBJECTIVE Cytochrome P450 2C19 (CYP2C19) and CYP2D6 are important xenobiotic metabolic enzymes and both show considerable genetic variability between Orientals and Caucasians. There are known marked heterogeneity in susceptibility to various cancers and hypertension among Chinese Mongolian, Hui and Han ethnic groups, but the molecular(More)
Herpes simplex virus type 1 (HSV-1) plasmid vectors have a number of attractive features for gene transfer into neurons. In particular, the large size of the HSV-1 genome suggests that HSV-1 vectors might be designed to accommodate large inserts. We now report the construction and characterization of a 51 kb HSV-1 plasmid vector. This vector was efficiently(More)
