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
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, ora double-stranded RNA including at least 20 contiguous nucleotides in the aforementioned untranslated region, or DNA encoding said double-stranded RNA.
