- the subject matter disclosed herein relates to the production of artificial recombinant chromosomes and cells comprising the same.
- Transgenic animals are animals that have introduced artificial traits, and are used for research on various diseases, mechanisms, and development of therapeutic agents.
- the method for producing a transgenic animal includes introducing a desired trait into an animal cell. For this, a method using a cloning vector is currently being used.
- the method using a cloning vector is a method in which a desired trait, that is, a vector artificially created by cloning a target gene to be expressed in a transgenic animal, is transferred to an animal cell and inserted into the genome.
- This method uses a plasmid, a bacterial artificial chromosome (BAC) or a yeast artificial chromosome (YAC).
- BAC or YAC is a DNA construct capable of carrying a larger fragment (150-350 kbp) than a plasmid, and is widely used for transformation.
- BAC or YAC has the advantage of being able to carry a relatively large fragment compared to a plasmid, and thus is used for transduction of a gene of interest having a large size.
- a plurality of BACs or YACs are required.
- a mouse cell into which a human immunoglobulin (Ig) gene is introduced in order to produce the mouse, a mouse cell into which a human immunoglobulin (Ig) gene is introduced must be produced.
- a vector for transformation by cloning a human immunoglobulin heavy (IGH) gene having a size of 1250 kilobases (kb) must be constructed.
- the transformation vector is BAC, at least 4 to 9 BACs each having different DNA fragments are made. These BACs are sequentially introduced into mouse cells and inserted into the genome.
- the first BAC is introduced into the mouse cell and inserted into the genome, and the mouse cell into which the first BAC is inserted is selected.
- a second BAC is introduced into the selected mouse cells and inserted into the genome, and the mouse cells into which the second BAC has been inserted are selected again.
- the above process should be repeated. This repetitive process becomes a factor that reduces the yield of mouse cells into which the full length of the target gene is inserted.
- problems such as time consumption and cost consumption due to repetition of the transduction and selection process occur.
- the time and cost of creating multiple BACs is considerable.
- the present invention has developed a transformation technique using recombination between chromosomes and chromosomes.
- the content disclosed by the present specification shows that by producing an artificial recombinant chromosome through recombination between chromosomes, it is possible to replace the existing system using transformation vectors such as BAC and YAC.
- the method disclosed by this specification discloses a transduction (transformation) method using a chromosome that is not BAC or YAC.
- the transduction method using a chromosome is a process of introducing one chromosome into an animal cell instead of BAC or YAC, which was used in the previous method, and recombining the target gene into the animal's genome, thereby transforming the transformed (transduced) animal cell. To make.
- the transduction method using a chromosome disclosed by the present specification can be largely divided into three processes.
- the first is a process of artificially manipulating a target gene, that is, a chromosome containing a gene for transduction (transformation) and a chromosome into which the target gene is to be inserted, to contain elements necessary for recombination.
- This process may be performed in a donor cell having a chromosome containing a target gene and a acceptor cell having a chromosome into which the target gene is to be inserted.
- the element necessary for recombination may be a factor that enables recombination using a recombinant enzyme or homologous recombination.
- the site recognized by the recombinant enzyme can be said to be an element necessary for recombination.
- an element necessary for recombination may be loxP.
- an element required for recombination may be FRT.
- the purpose of the above process is to provide a site that can be recognized by a recombinant enzyme during recombination between chromosomes or a homologous site for homologous recombination.
- the second is microcell production and cell fusion process using the same.
- This process uses the cells (donor cells) produced in the previous process, and the microcells produced through this process have a chromosome containing a target gene into which an element necessary for recombination is inserted.
- the microcells produced through this process have a fragment of a chromosome containing a target gene into which an element necessary for recombination is inserted, wherein the fragment includes a target gene into which an element necessary for recombination is inserted.
- the above process may be performed using a known technique, MMCT (Microcell-Mediated Chromosome Transfer).
- MMCT is a technique commonly used to transfer chromosomes from donor cells to receptor cells (Thorfinn Ege et al., 1974; Thorfinn Ege et al., 1977).
- the microcells produced through the above process include a chromosome or a fragment of a chromosome, and the chromosome or fragment of a chromosome is not a cloning vector such as a plasmid replicated through artificial cloning.
- the chromosome or chromosome fragment contains an element necessary for recombination, and the contained element required for recombination is paired with an element required for recombination contained in a receptor cell.
- the produced microcells are fused with the receptor cells.
- the chromosome containing the target gene into which the element necessary for recombination of the donor cell is inserted is introduced (transferred) into the recipient cell through the fusion of the microcells.
- the third is a cell production process that includes a recombinant enzyme or an artificial recombinant chromosome using homologous recombination.
- This process is a process of inducing recombination between chromosomes by treating the cells produced in the previous process, that is, the fusion cells produced through cell fusion, with a recombinant enzyme or a factor induced by homologous recombination.
- the recombinant enzyme is processed in this process, recombination between the sites recognized by the recombinant enzyme, that is, between chromosomes having elements necessary for the recombination, is induced.
- the generated artificial recombinant chromosome is a chromosome in which a target gene is inserted into a chromosome into which the target gene is to be inserted, that is, a desired trait (target gene) is inserted.
- the generated artificial recombinant chromosome is a chromosome in which a part of the chromosome of a donor cell (i.e., the target gene) is inserted into the chromosome of the recipient cell (i.e., the chromosome into which the target gene is to be inserted), and is produced by interchromosomal recombination. It is a chromosome.
- Transgenic animals can be produced using cells having the artificial recombinant chromosome.
- a human immunoglobulin heavy (IGH) gene having a size of 1250 kilobases (kb) must be introduced into the mouse cell.
- a chromosome containing a human immunoglobulin heavy (IGH) gene that is, a human chromosome 14 is introduced into a mouse cell.
- the chromosome containing the human IGH gene is a target gene, that is, a chromosome artificially engineered to contain an element necessary for recombination at both ends of the human IGH gene.
- Microcell-Mediated Chromosome Transfer may be used.
- microcells and mouse cells are fused to form a fused cell, wherein the fused cell includes the entire chromosome of the mouse cell and the human chromosome 14.
- the fusion cell is treated with a recombinant enzyme to induce recombination between the introduced human chromosome 14 and the desired chromosome (eg, mouse chromosome 12 containing a mouse IGH gene) to be inserted.
- the desired chromosome into which the target gene is to be inserted is the locus where the target gene is desired to be inserted (eg, the mouse IGH gene Both ends) are artificially engineered chromosomes to contain elements necessary for recombination.
- the human IGH gene of the human chromosome 14 is inserted or replaced into the desired locus (eg, mouse IGH locus) in which the target gene is inserted.
- the human IGH gene can be inserted upstream or downstream of the mouse IGH locus.
- the mouse IGH gene may be replaced with a human IGH gene at the mouse IGH locus.
- Recombination insertion or replacement insertion
- Recombination can be varied depending on the design of the elements required for recombination.
- the example described above is only an example, and the target gene can be selectively changed and diversified.
- the transduction method using a chromosome disclosed by the present specification uses the chromosome itself present in the cell without an artificial cloning step, and has technical differentiation from the system using transformation vectors such as BAC and YAC.
- the transduction method using the chromosome disclosed by the present specification is to introduce a target gene, particularly, a target gene of a large size, sequential introduction over several times using a transformation vector such as BAC and YAC of the existing method. It is a new technology that can solve the problems of the existing method (efficiency, time, cost, etc.) by significantly reducing the number of times.
- the transduction method using a chromosome disclosed by the present specification does not clone the gene to be introduced, that is, the entire sequence of the target gene.
- the transduction method using a chromosome disclosed by the present specification involves recombining the chromosome by processing a recombinant enzyme (or a factor induced by homologous recombination) after fusion of cells, Does not fuse.
- the transduction method using the chromosome is performed to introduce each target gene into the genome, and at this time, the trait using the chromosome
- the step of fusing the microcells to introduce the second target gene into the cells into which the first target gene generated through the introduction method has been introduced is further performed.
