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...

Designing E1 deleted adenoviral vector by homologous recombination.

BACKGROUND 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 ...

A simple method for constructing E1- and E1/E4-deleted recombinant adenoviral vectors.

We previously developed a two-plasmid in vitro ligation method that did not require a recombination step to produce new recombinant E1- or E1/E3-deleted adenoviral vectors. In this study, we have modified the system to improve the simplicity of vector construction and, in addition, to allow for production of an E1/E4-deleted vector.

Homologous recombination

DNA damage, in the form of DNA double-strand breaks, poses a considerable threat to genomic integrity and cell survival. If left unrepaired, a single double-strand break is sufficient to cause cell death and, if repaired inappropriately, a double-strand break may give rise to a potentially oncogenic translocation. Double-strand breaks in genomic DNA may arise accidentally in a number of ways, i...

Recombination: Homologous recombination branches out

Homologous recombination can be divided into three key steps: strand exchange, branch migration and resolution. The identification of a protein complex that catalyses branch migration and Holliday junction resolution argues that the mechanism of homologous recombination is conserved from bacteria to man.
