Title
(EN) INDUCTION OF EUKARYOTIC CELL IN EXON SKIPPING
(JA) 真核細胞におけるエキソンスキッピングの誘導
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a method for at least partially reducing production of an aberrant protein by a cell, in which so-called exon skipping is induced to the cell having an mRNA precursor containing an exon that codes the aberrant protein.

SOLUTION: In exon skipping, an altered product is obtained in the case where a mature mRNA having no skipped exon is created and a skipped exon codes an amino acid. Exon skipping is performed by giving a reagent which is capable of specifically inhibiting an exon inclusion signal of a given exon, which is an exon recognition sequence for example, to a cell. The exon inclusion signal can be interfered by a nucleic acid complementary to a part of exon. There is also provided the above-described nucleic acid that can be used for preparing a medical drug, which is a medical drug aimed at treatment of genetic diseases, for example.

【課題】細胞による異常型タンパク質の産生を少なくとも部分的に減少させるための方法であって、異常型タンパク質をコードするエキソンを含むmRNA前駆体を有する細胞にいわゆるエキソンスキッピングを誘導することを特徴とする方法を提供する。
【解決手段】エキソンスキッピングは、スキップされたエキソンを有さない成熟mRNAを生じ、スキップされたエキソンがアミノ酸をコードしている場合、変化した産物が得られる。エキソンスキッピングはあるエキソンのエキソン封入シグナル、例えばエキソン認識配列、を特異的に阻害することが可能な試薬を細胞に与えることによって行われる。該エキソン封入シグナルはエキソンの一部に対して相補的な核酸によって干渉することができる。医薬、例えば遺伝病の治療を目的とした医薬の調製に用いることができる上記の核酸も提供する。
