Provided is a novel nucleic acid molecule that is a single-stranded nucleic acid molecule including an expression inhibitory sequence that inhibits expression of a target gene. The single-stranded nucleic acid molecule includes, in sequence from the 5′ side to the 3′ side: a 5′ side region (Xc); an inner region (Z); and a 3′ side region (Yc). The inner region (Z) is composed of an inner 5′ side region (X) and an inner 3′ side region (Y) that are linked to each other. The 5′ side region (Xc) is complementary to the inner 5′ side region (X). The 3′ side region (Yc) is complementary to the inner 3′ side region (Y). At least one of the inner region (Z), the 5′ side region (Xc), and the 3′ side region (Yc) includes the expression inhibitory sequence.
提供的是一种新型核酸分子,它是一种单链核酸分子,包括一个抑制目标基因表达的表达抑制序列。该单链核酸分子从5'端到3'端的序列包括:一个5'端区域(Xc);一个内部区域(Z);以及一个3'端区域(Yc)。内部区域(Z)由内部5'端区域(X)和内部3'端区域(Y)组成,它们彼此连接。5'端区域(Xc)与内部5'端区域(X)互补。3'端区域(Yc)与内部3'端区域(Y)互补。内部区域(Z)、5'端区域(Xc)和3'端区域(Yc)中至少有一个包含表达抑制序列。
