Abstract: The process of aging and the development of age-related diseases are related to the emerging phenotypes of increasingly damaged and progressively malfunctioning proteomes. The present invention provides methods of preventing aging and age-related diseases in mammals by assessment of protein-specific oxidative damage. Methods of providing treatments that reduce intracellular reactive oxygen and/or nitrogen species, or protein-specific damage caused by reactive oxygen and/or nitrogen species, are disclosed. Furthermore, methods of screening for compounds that reduce intracellular reactive oxidative species, and/or molecules that prevent protein-specific damage by protecting the susceptible protein from such damage and therefore prevent or treat degenerative or age-related diseases, are also disclosed.

Abstract: Vaccines and therapeutic proteins, including polyclonal and monoclonal antibodies, must be maximally pure and stable in their most active native form. This is a requirement for their maximal efficacy, specificity and stability as well as for precluding immune responses against erroneous or damaged moieties. Similar considerations hold for proteins used in diagnostics, industry and research. The most frequent source of damage to proteins produced in living cells is the diverse product of oxidative damage. Two main sources of protein oxidation are the level of reactive oxygen species (ROS) and even more importantly the intrinsic susceptibility of proteins to oxidative damage. Methods for avoiding oxidative protein damage are disclosed, including providing for (i) a decrease in intracellular ROS levels and (ii) an increase in the intrinsic resilience of proteins to oxidative damage.

Abstract: This invention relates to chromosomal engineering via DNA repair process. The process of the invention comprises the steps of: 1) submitting at least one source of biological activity, e.g. Deinococcus radiodurans, to radiation, desiccation and/or chemical treatment liable to damage the DNA, so as to substantially shatter its chromosomes into short fragments; 2) annealing complementary single strand tails extended by the synthesis templated on partially overlapping DNA fragments of said shattered chromosomes; 4) converting the resulting long linear DNA intermediates into intact circular chromosomes, by means of a RecA dependent homologous recombination; whereas at least one foreign source of genetic material, e.g. DNA, can be introduced during steps 2 and/or 3; and 4) optionally separating and collecting the recombined chromosomes thus obtained.

Abstract: The present invention relates to methods for establishing a symbiosis, including the following steps: selecting an organism or an organelle to constitute the symbiont and an organism to constitute the host, the latter not existing naturally in a symbiotic relationship; contacting the symbiont and the host; and maintaining the combination of the symbiont and the host.

DNA sequences for which these methods are relevant include protein-encoding and non-coding sequences.

Abstract: The present invention relates to a process for allowing homologous recombination between non-identical DNA sequences of an organism and various applications thereof.

Abstract: A method for detecting mutations and polymorphisms, including single nucleotide polymorphisms (SNP's), is based on the use of RecA-like recombinase protein and a MutS-like mismatch binding protein. RecA coated, specific DNA oligonucleotide probes (RecA filaments) are used for homology searching in duplex DNA. Location of homologous sequences results in the formation of D-loop structures containing a duplex region comprised of the oligonucleotide probe and one strand of the test DNA. Mismatches or unpaired bases in the duplex region are substrates for MutS binding. Co-localization of MutS and oligonucleotide or RecA labels is diagnostic of specific sequence differences between the probe and test DNAs. Also provided are compositions and kits useful for practicing the methods of the present invention.

Abstract: The present invention relates to a process of recombination in vivo of partially homologous DNA sequences having up to 30% of base mismatches. According to its essential characteristic, said sequences are placed together in cells or an organism of which the enzymatic mismatch repair system is defective or has been transitorily inactivated by saturation for the time to obtain recombination between said DNA sequences or in using mutants which increase the intergeneric recombination.

Abstract: A method of producing plasmids with heteroduplex DNA sequences, in which probe plasmids containing DNA inserts that correspond to probe sequences and test plasmids containing DNA inserts that correspond to a population of test sequences are first constructed. The vector portions of the plasmids used in these constructions have similar sequences. When test and probe plasmids are cleaved with appropriate restriction enzymes and then denatured to separate strands, complementary regions of the linear strands which correspond to vector sequences can anneal. The molecules that harbor test and probe inserts that are related by sequence complementarity form non-covalently closed circular molecules. These molecules can replicate after transformation into an appropriate host organism. There is a replication bias against plasmids which anneal through vector sequences, but which do not contain homologous probe and test inserts.
