Induction of exon skipping in eukaryotic cells
First Claim
1. A method for directing splicing of a pre-mRNA in a cell capable of performing a splicing operation to reduce the production of an undesired protein in the cell, the method comprising:
- contacting the pre-mRNA in the cell with an antisense-oligonucleotide capable of specifically inhibiting an exon inclusion signal of at least one exon in the pre-mRNA, wherein the antisense-oligonucleotide is directed against the interior of the at least one exon and contains between 14-40 nucleotides.

Abstract
Described is a method for at least in part decreasing the production of an aberrant protein in a cell, the cell comprising pre-mRNA comprising exons coding for the protein, by inducing so-called exon skipping in the cell. Exon-skipping results in mature mRNA that does not contain the skipped exon, which leads to an altered product of the exon codes for amino acids. Exon skipping is performed by providing a cell with an agent capable of specifically inhibiting an exon inclusion signal, for instance, an exon recognition sequence, of the exon. The exon inclusion signal can be interfered with by a nucleic acid comprising complementarity to a part of the exon. The nucleic acid, which is also herewith provided, can be used for the preparation of a medicament, for instance, for the treatment of an inherited disease.

5. A method for at least in part decreasing the production of an aberrant protein in a cell, the cell comprising pre-mRNA comprising exons coding for the protein, the method comprising:
providing the cell with an antisense-oligonucleotide capable of specifically inhibiting an exon inclusion signal of at least one of the exons, wherein the antisense-oligonucleotide is directed against the interior of the at least one exon and contains between 14-40 nucleotides, the method further comprising allowing translation of mRNA produced from splicing of the pre-mRNA.

12. A method for determining whether a nucleic acid, having complementarity to a part of an exon, is capable of specifically inhibiting an exon inclusion signal of the exon, the method comprising:
-
providing a cell having a pre-mRNA containing the exon, with the nucleic acid, culturing the cell to allow the formation of an mRNA from the pre-mRNA, and determining whether the exon is absent from the mRNA. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
