Riassunto

The potential now exists in many experimental systems to transfer a cloned, modified gene back into the genome of the host organism. In the ideal situation, the cloned gene is returned to its homologous location in the genome and becomes inserted at the target locus. This process is a controlled means for the repair of DNA damage and ensures accurate chromosome disjunction during meiosis. The paradigm for thinking about the mechanism of this p- cess has emerged primarily from two sources: (1) The principles of reaction mechanics have come from detailed biochemical analyses of the RecA protein purified from Escherichia coli; and (2) the principles of information transfer have been derived from genetic studies carried out in bacteriophage and fungi. A compelling picture of the process of homologous pairing and DNA strand exchange has been influential in directing investigators interested in gene t- geting experiments. The ability to find and pair homologous DNA molecules enables ac- rate gene targeting and is the central phenomenon underlying genetic recombi- tion. Biochemically, the overall process can be thought of as a series of steps in a reaction pathway whereby DNA molecules are brought into homologous register, the four-stranded Holliday structure intermediate is formed, hete- duplex DNA is extended, and DNA strands are exchanged. Not much is known about the biochemical pathway leading to homologous recombination in euka- otes.

Su questo libro

Dalla quarta di copertina

In Gene Targeting Protocols, a panel of innovative investigators present in readily reproducible detail the latest techniques for gene replacement, gene knockout, and gene repair in both animals and plants. These expert researchers review the best gene transfer vehicles (liposomes, PEI, and EPD), discuss the parameters that affect vector uptake, and detail successful methods for gene targeting (Cre-ox, and adeno and adeno-associated viruses). The methods include two fundamentally different approaches to gene targeting- one using a fusion protein to deliver a vector to a virus for possible therapeutic effect, and one entailing an episomal-based Epstein-Barr vector that can modulate the chromatin assembly process, and thus overcome a serious barrier to therapeutic gene targeting. The book also has several techniques for using oligonucleotides in gene targeting, a methodology that may revolutionize the entire field.
Innovative and wide ranging, Gene Targeting Protocols offers today's researchers robust and proven gene-targeting techniques that are essential to understanding and regulating biological processes at the genetic level.
