Targeting site-specific chromosome integration.
The concept of gene therapy was introduced with great promise and high expectations. However, what appeared simple in theory has not translated into practice. Despite some success in clinical trials, the research community is still facing an old problem: namely, the need for a vector that can deliver a gene to target cells without adverse events while maintaining a long-term therapeutic effect....
متن کاملSite-specific integration by adeno-associated virus.
Adeno-associated virus (AAV) has attracted considerable interest as a potential vector for gene delivery. Wild-type virus is notable for the lack of association with any human disease and the ability to stably integrate its genome in a site-specific manner in a locus on human chromosome 19 (AAVS1). Use of a functional model system for AAV DNA integration into AAVS1 has allowed us to conclude th...
متن کاملSite-specific integration with bacteriophage ΦC31 integrase.
Few nonviral techniques exist for efficient and stable eukaryotic gene transfer and fewer still are broadly useful in both cell culture and whole-organism applications. C31 integrase, a site-specific bacteriophage recombinase, is able to catalyze chromosomal transgene insertion under a diverse range of experimental and therapeutic conditions. The enzyme recognizes and catalyzes unidirectional r...
متن کاملSite-specific chromosomal integration of large synthetic constructs
We have developed an effective, easy-to-use two-step system for the site-directed insertion of large genetic constructs into arbitrary positions in the Escherichia coli chromosome. The system uses lambda-Red mediated recombineering accompanied by the introduction of double-strand DNA breaks in the chromosome and a donor plasmid bearing the desired insertion fragment. Our method, in contrast to ...
متن کاملRepetitive, marker-free, site-specific integration as a novel tool for multiple chromosomal integration of DNA.
We present a tool for repetitive, marker-free, site-specific integration in Lactococcus lactis, in which a nonreplicating plasmid vector (pKV6) carrying a phage attachment site (attP) can be integrated into a bacterial attachment site (attB). The novelty of the tool described here is the inclusion of a minimal bacterial attachment site (attB(min)), two mutated loxP sequences (lox66 and lox71) a...
