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 کاملHomologous 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...
متن کاملRecombination: 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.
متن کاملIs homologous recombination really an error-free process?
Homologous recombination (HR) is an evolutionarily conserved process that plays a pivotal role in the equilibrium between genetic stability and diversity. HR is commonly considered to be error-free, but several studies have shown that HR can be error-prone. Here, we discuss the actual accuracy of HR. First, we present the product of genetic exchanges (gene conversion, GC, and crossing over, CO)...
متن کاملThe many facets of homologous recombination at telomeres
The ends of linear chromosomes are capped by nucleoprotein structures called telomeres. A dysfunctional telomere may resemble a DNA double-strand break (DSB), which is a severe form of DNA damage. The presence of one DSB is sufficient to drive cell cycle arrest and cell death. Therefore cells have evolved mechanisms to repair DSBs such as homologous recombination (HR). HR-mediated repair of tel...
