Definitions
- the present invention relates to an antisense oligomer that enables skipping of the 51st exon of the human dystrophin gene and a pharmaceutical composition containing the oligomer.
- DMD Duchenne muscular dystrophy
- DMD is known to be caused by mutations in the dystrophin gene.
- the dystrophin gene exists on the X chromosome and is a huge gene consisting of 2.2 million bases of DNA.
- the mRNA that is transcribed from DNA to the mRNA precursor, and then the intron is removed by splicing to which 79 exons are bound becomes 11,058 bases.
- This mRNA is translated into 3,685 amino acids to produce dystrophin protein.
- Dystrophin protein is involved in maintaining the membrane stability of muscle cells, and is necessary to make muscle cells difficult to break. Since the dystrophin gene of DMD patients has a mutation, dystrophin protein having a function in muscle cells is hardly expressed. Therefore, in the DMD patient body, the structure of muscle cells cannot be maintained, and a large amount of calcium ions flow into the muscle cells. As a result, a reaction similar to inflammation occurs and fibrosis advances, making it difficult for muscle cells to regenerate.
- Becker muscular dystrophy is also caused by mutations in the dystrophin gene, but its symptoms are generally weaker than those of DMD, although the symptoms are weaker than muscular atrophy.
- the difference in clinical symptoms between DMD and BMD is thought to be due to whether the amino acid reading frame when dystrophin mRNA is translated into dystrophin protein due to mutation is destroyed or maintained (non-patented) Reference 1).
- DMD has a mutation that shifts the amino acid reading frame, so that almost no functional dystrophin protein is expressed, but in BMD, a part of the exon is deleted due to the mutation, but the amino acid reading frame is maintained. Therefore, a dystrophin protein having a function although it is incomplete is produced.
- Exxon skipping is expected as a treatment method for DMD.
- This method restores the amino acid reading frame of dystrophin mRNA by modifying splicing and induces the expression of dystrophin protein partially restored in function (Non-patent Document 2).
- the part of the amino acid sequence targeted for exon skipping will be lost.
- the dystrophin protein expressed by this treatment is shorter than the normal one, but the function of stabilizing muscle cells is partially retained because the amino acid reading frame is maintained.
- exon skipping is expected to cause DMD to exhibit symptoms similar to milder BMD.
- the exon skipping method has been tested in human DMD patients through animal experiments using mice and dogs.
- Exon skipping can be induced by binding of antisense nucleic acids targeting either or both 5 'or 3' splice sites, or the interior of exons. Exons are only included in mRNA if both splice sites are recognized by the spliceosome complex. Thus, exon skipping can be induced by targeting the splice site with an antisense nucleic acid. In addition, it is thought that the binding of SR protein to the exon splicing enhancer (ESE) is necessary for the exon to be recognized by the splicing mechanism. Targeting ESE can also induce exon skipping. it can.
- ESE exon splicing enhancer
- Non-patent Document 3 Since the mutation of the dystrophin gene varies depending on the DMD patient, an antisense nucleic acid corresponding to the location and type of the gene mutation is required. So far, antisense nucleic acids that induce exon skipping for all 79 exons have been created by Steve Wilton et al. Of the University of Western Australia (Non-patent Document 3), and 39 types by Annemieke Aartsma-Rus et al. Of the Netherlands. An antisense nucleic acid that induces exon skipping of exons has been produced (Non-patent Document 4).

- the gene is an mRNA precursor, ie pre-mRNA.
- the human dystrophin gene is present at locus Xp21.2.
- the human dystrophin gene has a size of 2.2 million base pairs and is the largest known human gene.
- the coding region of the human dystrophin gene is only 14 kb, and the coding region is dispersed in the dystrophin gene as 79 exons (Roberts, RG., Et al., Genomics, 16: 536-538 ( 1993)).
- Pre-mRNA a transcript of the human dystrophin gene, is spliced to produce a 14 kb mature mRNA.
- the base sequence of the human wild-type dystrophin gene is known (GenBank Accession No. NM_004006).
- the base sequence of exon 51 of the human wild type dystrophin gene is shown in SEQ ID NO: 3.

- Hybridization methods include, for example, “Sambrook & Russell, Molecular Cloning: A Laboratory Manual Manual Vol. Can be used.
- stringent conditions may be any of low stringent conditions, medium stringent conditions, and high stringent conditions.
- Low stringent conditions are, for example, conditions of 5 ⁇ SSC, 5 ⁇ Denhardt's solution, 0.5% SDS, 50% formamide, 32 ° C.
- Medium stringent conditions include, for example, 5 ⁇ SSC, 5 ⁇ Denhardt's solution, 0.5% SDS, 50% formamide, 42 ° C. or 5 ⁇ SSC, 1% 1SDS, 50 mM Tris-HCl (pH 7. 5) 50% formamide at 42 ° C.

By doing so, it is possible to achieve the same stringency. .
