Nucleic acid inhibiting expression of the MEX3B gene, MEX3B gene expression inhibitor, method for inhibiting MEX3B gene expression, and prophylactic or therapeutic agent for disease caused by MEX3B gene expression
View Patent ↗A nucleic acid which can inhibit expression of the MEX3B gene with low cytotoxicity as a side effect, an MEX3B gene expression inhibitor which contains said nucleic acid, a method for inhibiting MEX3B gene expression, and a prophylactic or therapeutic agent for disease caused by MEX3B gene expression are provided. This nucleic acid, which inhibits the expression of the MEX3B gene, is an antisense oligonucleotide having a sequence complementary to an oligonucleotide that contains at least 10 contiguous nucleotides in an untranslated region in an exon of the MEX3B gene, or a double-stranded RNA including at least 20 contiguous nucleotides in the aforementioned untranslated region, or DNA encoding said double-stranded RNA.
1. A method for inhibiting expression of MEX3B gene comprising administering a nucleic acid to a subject, wherein the nucleic acid is a nucleic acid inhibiting expression of MEX3B gene which is an antisense oligonucleotide having a sequence complementary to an oligonucleotide that comprises 12 to 20 contiguous nucleotides in an untranslated region in an exon of the MEX3B gene.
