This invention provides compounds, compositions and methods for modulating the expression of human GST-&#x3c0; using RNA interference. The RNA interference molecules can be used in methods for preventing or treating diseases such as malignant tumor. Provided are a range of siRNA structures, having one or more of nucleotides being modified or chemically-modified. Advantageous structures include siRNAs with 2'-deoxy nucleotides located in the seed region, as well as other nucleotide modifications.

RNA interference agents for GST-PI gene modulation

The present invention provides a nucleic acid molecule dimer that includes a first nucleic acid molecule having complementarity with at least part of a target nucleic acid molecule, and a second nucleic acid molecule having complementarity with the first nucleic acid molecule, wherein the first nucleic acid molecule has a linear form, the second nucleic acid molecule has a cyclic form, and the first and second nucleic acid molecules at least partially form a double strand.

RNA interference agents for GST-&#x3c0; gene modulation

This invention provides compounds, compositions and methods for modulating the expression of human GST-&#x3c0; using RNA interference. The RNA interference molecules can be used in methods for preventing or treating diseases such as malignant tumor. A nucleic acid molecule can have a) a polynucleotide sense strand and a polynucleotide antisense strand; b) each strand of the molecule being from 15 to 30 nucleotides in length; c) a contiguous region of from 15 to 30 nucleotides of the antisense strand being complementary to a sequence of an mRNA encoding GST-&#x3c0;; and d) at least a portion of the sense strand can be complementary to at least a portion of the antisense strand, and the molecule has a duplex region of from 15 to 30 nucleotides in length.

RNA agents for GST-Pi gene modulation

Provided are: a targeting molecule targeting a target cell which is selected from the group consisting of a stellate cell, a myofibroblast, a cancer-associated fibroblast, a tumor cell and a cell expressing STRA6, said targeting molecule being selected from the group consisting of (1) a peptide containing an amino acid sequence in the cell-binding region of RBP, (2) a variant peptide of the aforesaid peptide (1), said variant peptide having a comparable targetability to peptide (1), and (3) a peptide mimetic having a comparable targetability to peptide (1) or peptide (2); a targeting agent, a carrier, a complex and a medicinal composition each comprising the targeting molecule; a method for treating, examining, diagnosing or monitoring a disease related to the aforesaid target cell; a method for labeling, detecting or imaging the target cell, etc.
