8 . The composition of claim 1 , wherein the RNAi agent is ligated to one or more agents, the agent selected from a: one or more diagnostic compound, reporter group, cross-linking agent, nuclease-resistance conferring moiety, natural or unusual nucleobase, lipophilic molecule, cholesterol, lipid, lectin, steroid, uvaol, hecigenin, diosgenin, terpene, triterpene, sarsasapogenin, Friedelin, epifriedelanol-derivatized lithocholic acid, vitamin, carbohydrate, dextran, pullulan, chitin, chitosan, synthetic carbohydrate, oligo lactate 15-mer, natural polymer, low- or medium-molecular weight polymer, inulin, cyclodextrin, hyaluronic acid, protein, protein-binding agent, integrin-targeting molecule, polycationic, peptide, polyamine, peptide mimic, and/or transferrin.
9 . A method of treating a HSF1-related disease in an individual, comprising the step of administering to the individual a therapeutically effective amount of a composition comprising a RNAi agent comprising a sense strand and an antisense strand, wherein the antisense strand comprises at least 15 contiguous nucleotides differing by 0, 1, 2, or 3 nucleotides from the antisense strand of a RNAi agent specific to HSF1 provided in Table A1.
10 . The method of claim 9 , wherein the HSF1-related disease is cancer, or autoimmune, or a viral disease.
11 . The method of claim 9 , wherein the method further comprises the step of administering an additional treatment for cancer, or autoimmune, or a viral disease.
12 . The method of claim 11 , wherein the method further comprises the step of administering an additional RNAi agent to HSF1.
13 . A method of inhibiting the expression of the HSF1 gene in an individual, comprising the step of administering to the individual a therapeutically effective amount of a composition comprising a RNAi agent comprising a sense strand and an antisense strand, wherein the antisense strand comprises at least 15 contiguous nucleotides differing by 0, 1, 2, or 3 nucleotides from the antisense strand of a RNAi agent specific to HSF1 provided in Table A1.
14 . The method of claim 13 , wherein the HSF1-related disease is cancer, or autoimmune, or a viral disease.
