Mucopolysaccharidosis type I (MPS I) is a lysosomal disease caused by α-l-iduronidase (IDUA) deficiency and accumulation of glycosaminoglycans (GAG). Lentiviral vector encoding correct IDUA cDNA could be used for treating MPS I. To optimize the lentiviral vector design, 9 constructs were designed by combinations of various promoters, enhancers, and codon optimization. After in vitro transfectio...
Thirty-three pestiviruses isolated from bovines on different farms in Chile were characterized at the molecular level. The 5'-untranslated region (5'UTR) of the isolates was amplified by reverse transcription-polymerase chain reaction (RT-PCR) and subsequently digested with restriction enzymes (RE) Bgl I, Xho I and Pst I. Furthermore, the isolates were amplified by differential RT-PCR, which se...
INTRODUCTION Since the concept of reprogramming mature somatic cells to generate induced pluripotent stem cells (iPSCs) was demonstrated in 2006, iPSCs have become a potential substitute for embryonic stem cells (ESCs) given their pluripotency and "stemness" characteristics, which resemble those of ESCs. We investigated to reprogram fibroblast-like synoviocytes (FLSs) from patients with rheumat...
Lentiviral vectors are efficient vehicles for stable gene transfer in both dividing and non-dividing cells. This feature among others makes lentiviral vectors a powerful tool in molecular research. However, the use of lentiviruses in research studies and clinical trials requires a precise and validated titration method. In this study, we describe a qPCR-based approach for estimation of lentivir...
BACKGROUND: Although lentiviral vectors have been widely used for in vitro and in vivo gene therapy researches, there have been few studies systematically examining various conditions that may affect the determination of the number of viable vector particles in a vector preparation and the use of Multiplicity of Infection (MOI) as a parameter for the prediction of gene transfer events. METHODS:...
Genotypes and subgenotypes of bovine viral diarrhea virus (BVDV) field isolates from Japan, Germany and the United States of America (USA) were identified, and the prevalent pattern of BVDV in individual countries was estimated genetically. Subgenotypes were determined based on phylogenetic analyses of nucleotide sequences of a part of the E2-coding gene of BVDV. Forty-five, 61 and 56 BVDV stra...
Substitution of lentiviral cis-acting elements by heterologous sequences might allow the safety of lentiviral vectors to be enhanced by reducing the risk of homologous recombination and vector mobilization. Therefore, a substitution and deletion analysis of the R region of simian immunodeficiency virus (SIV)-based vectors was performed and the effect of the modifications on packaging and transf...
