There are two different co-expression systems including bicistronic; dual-vector or two-promoter to express two different genes simultaneously and also to study protein-protein interactions. Bicistronic system has disadvantages e.g. compared with two-promoter system. In this paper, a simple method based on spliced overlap extension by polymerase chain reaction (SOE-PCR) technique was demonstrat...

objective: in this study, two conserved genes (m1 and np) of influenza virus were expressed in a bicistronic vector in order to develop a universal gene based vaccine. materials and methods: plasmids m1-pires2-egfp, pires2-np were constructed by cloning the pcr products of m1 and np genes which were amplified from the a/peurto rico/8/34 (h1n1) influenza virus strain into the plasmid expression...
Due to the lack of an adequate conventional therapy against lower limb ischemia, gene transfer for therapeutic angiogenesis is seen as an attractive alternative. However, the possibility of side effects, due to the expression of large amounts of angiogenic factors, justifies the design of devices that express synergistic molecules in low controlled doses. We have developed an internal ribosome ...
Glioblastoma multiforme (GBM) is a deadly primary brain tumor. Conditional cytotoxic/immune-stimulatory gene therapy (Ad-TK and Ad-Flt3L) elicits tumor regression and immunological memory in rodent GBM models. Since the majority of patients enrolled in clinical trials would exhibit adenovirus immunity, which could curtail transgene expression and therapeutic efficacy, we used high-capacity aden...
Cell vaccines engineered to express immunomodulators have shown feasibility in eliminating leukemia in murine models. Vectors for efficient gene delivery to primary human leukemia cells are required to translate this approach to clinical trials. In this study, second-generation lentiviral vectors derived from human immunodeficiency virus 1 were evaluated, with the cytomegalovirus (CMV) promoter...
The efficacy and specificity of small interfering RNAs (siRNAs) are largely dependent on the siRNA sequence. Since only empirical strategies are currently available for predicting these parameters, simple and accurate methods for evaluating siRNAs are needed. To simplify such experiments, target genes are often tagged with reporters for easier readout. Here, we used a bicistronic vector express...
Stable expression of G protein coupled receptors in cell lines is a crucial tool for the characterization of the molecular pharmacology of receptors and the screening for new antagonists. However, in some instances, many difficulties have been encountered to obtain stable cell lines expressing functional receptors. Here, we addressed the question of vector optimization to establish cell lines e...
Manipulation of angiogenesis in vivo is an example of successful gene therapy strategies. Overexpression of angiogenic genes like VEGF, FGF or PDGF causes new vessel formation and improves the clinical state of patients. Gene therapy is a very promising procedure but requires large amounts of pharmaceutical-grade plasmid DNA. In this regard we have constructed a bicistronic plasmid DNA vector e...
