DNA Repair Protocols: Eukaryotic Systems: 113 (Methods in Molecular Biology, 113) - Tapa blanda

Sinopsis

The field of eukaryotic DNA repair is enjoying a period of remarkable growth and discovery, fueled by technological advances in molecular biol ogy, protein biochemistry, and genetics. Notahle achievements include the molecular cloning of multiple genes associated with classical human repair disorders, such as xeroderma pigmentosum, Cockayne syndrome, and ataxia telangiectasia; elucidation of the core reaction of nucleotide excision repair (NER); the discovery that certain NER proteins participate not only in repair, but also in transcription; recognition of the crucial role played by mismatch repair processes in maintenance of genome stability and avoidance of cancer; the findings that the tumor suppressor protein p53 is mutated in many types of cancer, and has a key role in directing potentially malignant, genotoxin-dam aged cells towards an apoptotic fate; and the discovery and elaboration of DNA darnage (and replication) checkpoints, which placed repair phenomenol ogy firmly within a cell-cycle context. Of course, much remains to be learned about DNA repair. Tothat end, DNA Repair Protocols: Eukaryotic Systems is about the tools and techniques that have helped propel the DNA repair field into the mainstream of biological research. DNA Repair Protoco/s: Eukaryotic Systems provides detailed, step-by step instructions for studying manifold aspects of the eukaryotic response to genomic injury. The majority of chapters describe methods for analyzing DNA repair processes in mammalian cells. However, many ofthose techniques can be applied with only minor modification to other systems, and vice versa.
