    摘要: The present invention relates to a multifunctional short interfering nucleic acid (siNA) having a structure of Formula MF-III: wherein each X, X′, Y, and Y′ is independently an oligonucleotide of length about 15 nucleotides to about 50 nucleotides; X comprises a nucleotide sequence that is complementary to a nucleotide sequence present in region Y′; X′ comprises a nucleotide sequence that is complementary to a nucleotide sequence present in region Y; one or more of X, X′, Y, and Y′ is independently complementary to a first, second, third, or fourth target sequence, respectively, or a portion thereof; and W represents a nucleotide or non-nucleotide linker that connects sequences Y′ and Y, wherein the siNA directs cleavage of the first, second, third, and/or fourth target sequence via RNA interference.
