Designing E1 Deleted Adenoviral Vector by Homologous Recombination
Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...
متن کاملNascent DNA synthesis during homologous recombination is synergistically promoted by the rad51 recombinase and DNA homology.
In this study, we exploited a plasmid-based assay that detects the new DNA synthesis (3' extension) that accompanies Rad51-mediated homology searching and strand invasion steps of homologous recombination to investigate the interplay between Rad51 concentration and homology length. Mouse hybridoma cells that express endogenous levels of Rad51 display an approximate linear increase in the freque...
متن کاملNitric oxide-induced homologous recombination in Escherichia coli is promoted by DNA glycosylases.
Nitric oxide (NO*) is involved in neurotransmission, inflammation, and many other biological processes. Exposure of cells to NO* leads to DNA damage, including formation of deaminated and oxidized bases. Apurinic/apyrimidinic (AP) endonuclease-deficient cells are sensitive to NO* toxicity, which indicates that base excision repair (BER) intermediates are being generated. Here, we show that AP e...

متن کاملInitiation of genetic recombination: homologous pairing between duplex DNA molecules promoted by recA protein.
recA protein has been shown to promote hydrogen bonding between single-stranded DNA fragments and duplex DNA molecules homologous to them. However, genetic and biochemical evidence indicates that genetic exchanges generally take place between duplex molecules. We therefore chose to study the interactions promoted by recA protein between intact duplex DNA molecules and molecules containing gaps ...
