AIMS Bacteriophage vectors have potential as gene transfer and vaccine delivery vectors because of their low cost, safety and physical stability. However, little is known concerning phage-mediated gene transfer in mammalian hosts. We therefore performed experiments to examine phage-mediated gene transfer in vivo. METHODS AND RESULTS Mice were inoculated with recombinant lambda phage containin...

background: the aim of this study was to evaluate over expression of epidermal growth factor receptor (egfr) gene in localized prostate cancers and determine its relation with clinical and pathological factors affecting the progression of the disease. methods: in the tissue samples of the patients with prostate cancer undergoing radical prostatectomy, egfr expression was evaluated by immunohist...

Background: Crohn’s disease (CD) and ulcerative colitis (UC) are two major clinical presentations of inflammatory bowel disease (IBD). Many novel candidate genes have been found to be associated with increased risk for IBD. Recently IL-23 receptor gene is identified as an IBD associated gene in genome-wide studies. Objective: To ascertain whether rs7517847 and rs1004819 SNPs in the IL-23 recept...

human mitochondrial dna (mtdna) is 16,569 base pairs (bp) in length, coding for 37 genes. during the course of evolution, nearly all the genes expressing ribosomal proteins and ribosomal rnas (rrna) genes have been transferred from the mitochondria to the nucleus. however, mitochondrial dna contains two ribosomal rnas genes (12s and 16s), which have not yet transferred to the nucleus. these two...

Recombinant retroviral vectors are still the most common gene delivery vehicles for gene therapy purposes, especially for construction of genetically modified tumor vaccines (GMTV). However, these vehicles are characterized by relatively low titre and in the case of many tumor cell lines, low transduction efficiency. We constructed bicistronic retroviral vector pseudotypes of amphotropic murine...

A transgenic animal as originally defined by Gordon and Ruddle (1981), is an organism carrying recombinant molecules that were intentionally introduced by human intervention. Classically this entailed the stable integration of the transgene within the host animal’s genome and its transmission to progeny through normal breeding programmes. Transgenic chicken holds great promise in basic biologic...

Peripheral blood lymphocytes (PBLs) are key target cells for gene therapy of a number of inherited and acquired blood disorders. We have systematically compared four retroviral vectors, designed according to different strategies, for their efficiency in transfer and expression in human PBLs of the same reporter gene. The receptor gene used in the study codes for the human low-affinity nerve gro...
