[0085] A. Human Non-Coding Chimeric Mitochondrial RNAs (ncmtRNAs)
[0086] Human cells express a number of unique chimeric mitochondrial RNA molecules. These molecules are non-coding (i.e., they are not known to serve as a template for the translation of a protein) and comprise the 16S mitochondrial ribosomal RNA covalently linked at the 5 end to an inverted repeat sequence. Non-coding chimeric mitochondrial RNA molecules are found in two forms: sense and antisense.
[0087] The sense non-coding chimeric mitochondrial RNA (SncmtRNA) molecule corresponds to the 16S mitochondrial ribosomal RNA transcribed from the H-strand of the circular mitochondrial genome. Covalently linked to the 5 end of this RNA molecule is a nucleotide sequence corresponding to the inverted repeat sequence of the 16S mitochondrial ribosomal RNA, transcribed from the L-strand of the mitochondrial genome. The size of the inverted repeat sequence in the SncmtRNA can vary from about 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500, 525, 550, 575, 600, 625, 650, 675, 700, 725, 750, 775, or 800 nucleotides or more to between about 100-200, 150-250, 200-300, 250-350, 400-500, 450-550, 500-600, 550-650, 600-700, 650-750, or 700-800 nucleotides or more, including any number in between these values. In one embodiment, the inverted repeat sequence in the SncmtRNA corresponds to a fragment of 815 nucleotides of the RNA transcribed from the L-strand of the 16S gene of the mitochondrial genome. In another embodiment, the SncmtRNA comprises a sequence corresponding to SEQ ID NO:1, SEQ ID NO:2, or SEQ ID NO:3 as provided in
[0088] The antisense non-coding chimeric mitochondrial RNA (ASncmtRNA) molecule corresponds to the 16S mitochondrial ribosomal RNA transcribed from the L-strand of the circular mitochondrial genome. Covalently linked to the 5 end of this RNA molecule is a nucleotide sequence corresponding to the inverted repeat sequence of the 16S mitochondrial ribosomal RNA gene, transcribed from the H-strand of the mitochondrial genome. The size of the inverted repeat sequence in the ASncmtRNA can vary from about 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500, 525, 550, 575, 600, 625, 650, 675, 700, 725, 750, 775, 800 nucleotides or more to between about 100-200, 150-250, 200-300, 250-350, 400-500, 450-550, 500-600, 550-650, 600-700, 650-750, or 700-800 or more, including any number in between these values. In another embodiment, the ASncmtRNA comprises a sequence corresponding to SEQ ID NO:4, SEQ ID NO:5, or SEQ ID NO:6 as provided in

[0105] a. Oligonucleotide Modifications
[0106] The naturally occurring internucleoside linkage of RNA and DNA is a 3 to 5 phosphodiester linkage. The oligonucleotides, for example, the antisense oligonucleotides used to anneal with ASncmtRNA for subsequent RNase H treatment, or the RNA molecules as described herein, such as the RNA molecules resulting from ASncmtRNA cleaved by RNase H, ASncmtRNA sequentially cleaved by RNase H and exonuclease, or ASncmtRNA sequentially cleaved by RNase H, exonuclease and Dicer, including the RNA molecules described herein having the analogous sequences to RNA resulting from ASncmtRNA cleaved by RNase H, ASncmtRNA sequentially cleaved by RNase H and exonuclease, or ASncmtRNA sequentially cleaved by RNase H, exonuclease and Dicer, can have one or more modified, i.e. non-naturally occurring, internucleoside linkages. With respect to therapeutics, modified internucleoside linkages are often selected over oligonucleotides having naturally occurring internucleoside linkages because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for target nucleic acids, and increased stability in the presence of nucleases.
[0107] Oligonucleotides, such as an antisense oligonucleotides and RNA molecules or analogous DNA molecules as described herein having modified internucleoside linkages include internucleoside linkages that retain a phosphorus atom as well as internucleoside linkages that do not have a phosphorus atom. Representative phosphorus containing internucleoside linkages include, but are not limited to, phosphodiesters, phosphotriesters, methylphosphonates, phosphoramidate, and phosphorothioates. Methods of preparation of phosphorous-containing and non-phosphorous-containing linkages are well known.
[0108] In one embodiment, oligonucleotides targeted to the ASncmtRNA molecules described herein or the RNA molecules or analogous DNA molecules as described herein comprise one or more modified internucleoside linkages. In some embodiments, the modified internucleoside linkages are phosphorothioate linkages. In other embodiments, each internucleoside linkage of an oligonucleotide compound is a phosphorothioate internucleoside linkage.
[0109] As is known in the art, a nucleoside is a base-sugar combination. The base portion of the nucleoside is normally a heterocyclic base. The two most common classes of such heterocyclic bases are the purines and the pyrimidines. Nucleotides are nucleosides that further include a phosphate group covalently linked to the sugar portion of the nucleoside. For those nucleosides that include a pentofuranosyl sugar, the phosphate group can be linked to either the 2, 3 or 5 hydroxyl moiety of the sugar. In forming oligonucleotides, the phosphate groups covalently link adjacent nucleosides to one another to form a linear polymeric compound. In turn the respective ends of this linear polymeric structure can be further joined to form a circular structure, however, open linear structures are generally preferred. Within the oligonucleotide structure, the phosphate groups are commonly referred to as forming the internucleoside backbone of the oligonucleotide. The normal linkage or backbone of RNA and DNA is a 3 to 5 phosphodiester linkage.
[0110] Specific though nonlimiting examples of oligonucleotides, including RNA molecules or analogous DNA molecules as described herein, useful in the methods as described herein include oligonucleotides containing modified backbones or non-natural internucleoside linkages. As defined in this specification, oligonucleotides having modified backbones include those that retain a phosphorus atom in the backbone and those that do not have a phosphorus atom in the backbone. For the purposes of this specification, and as sometimes referenced in the art, modified oligonucleotides that do not have a phosphorus atom in their internucleoside backbone can also be considered to be oligonucleosides.
[0111] In some embodiments, modified oligonucleotide backbones include, for example, phosphorothioates, chiral phosphorothioates, phosphorodithioates, phosphotriesters, aminoalkylphosphotri-esters, methyl and other alkyl phosphonates including 3-alkylene phosphonates, 5-alkylene phosphonates and chiral phosphonates, phosphinates, phosphoramidates including 3-amino phosphoramidate and aminoalkylphosphoramidates, thiono-phosphoramidates, thionoalkylphosphonates, thionoalkylphospho-triesters, selenophosphates and boranophosphates having normal 3-5 linkages, 2-5 linked analogs of these, and those having inverted polarity wherein one or more internucleotide linkages is a 3 to 3, 5 to 5 or 2 to 2 linkage. Oligonucleotides having inverted polarity comprise a single 3 to 3 linkage at the 3-most internucleotide linkage i.e. a single inverted nucleoside residue which may be abasic (the nucleobase is missing or has a hydroxyl group in place thereof) can also be employed. Various salts, mixed salts and free acid forms are also included. Oligonucleotide backbones that do not include a phosphorus atom therein have backbones that are formed by short chain alkyl or cycloalkyl internucleoside linkages, mixed heteroatom and alkyl or cycloalkyl internucleoside linkages, or one or more short chain heteroatomic or heterocyclic internucleoside linkages. These include those having morpholino linkages (formed in part from the sugar portion of a nucleoside); siloxane backbones; sulfide, sulfoxide and sulfone backbones; formacetyl and thioformacetyl backbones; methylene formacetyl and thioformacetyl backbones; riboacetyl backbones; alkene containing backbones; sulfamate backbones; methyleneimino and methylenehydrazino backbones; sulfonate and sulfonamide backbones; amide backbones; and others having mixed N, O, S and CH.sub.2 component parts.
[0112] In other embodiments, both the sugar and the internucleoside linkage, i.e., the backbone, of the nucleotide units are replaced with novel groups. The base units are maintained for hybridization with an appropriate nucleic acid target compound. One such oligomeric compound, an oligonucleotide mimetic is referred to as a peptide nucleic acid (PNA). In PNA compounds, the sugar-backbone of an oligonucleotide is replaced with an amide containing backbone, in particular an aminoethylglycine backbone. The nucleobases are retained and are bound directly or indirectly to aza nitrogen atoms of the amide portion of the backbone. Representative United States patents that teach the preparation of PNA compounds include, but are not limited to, U.S. Pat. Nos. 5,539,082; 5,714,331; and 5,719,262, each of which is hereby incorporated by reference herein in their entirety. Further teaching of PNA compounds can be found in Nielsen et al., Science, 1991, 254, 1497-1500.
[0113] Representative United States patents that teach the preparation of the above phosphorus-containing and non-phosphorus-containing linkages include, but are not limited to, U.S. Pat.

[0139] B. Down Regulation of Proteins Involved in Apoptosis by Mito-miRs
[0140] Provided herein is a method of causing apoptosis in a tumor cell comprising contacting the tumor cell with one or more isolated RNA molecules or pharmaceutical composition comprising the one or more isolated RNA molecules as described herein.
[0141] In another aspect, the Mito-miRs prepared as discussed herein are useful for interfering with the expression of a number of proteins involved in the regulation of cancer cells, including proteins involved in one or more of apoptosis, the regulation of cell growth, cell migration, cell invasion and metastasis. In one embodiment, the protein is selected from the group consisting of survivin, cyclin D1, cyclin B1, FKBP38, N-cadherin and caveolin. Without being limited to mechanism, the Mito-miRs described herein can hybridize to untranslated regions (UTR) of mRNA from a variety of such proteins. The binding to the UTR inhibits the expression of the protein, resulting in a reduction in the protein in cells. This down regulation of these proteins involved in the regulation of cancer cells, including proteins involved in one or more of apoptosis, the regulation of cell growth, cell migration, cell invasion and metastasis, results in cancer cell death. As such, the treatment of cancer as described herein results from treatment with one or more Mito-miRs as described herein, or with an isolated RNA molecule as described herein that reacts in the cell to form one or more Mito-miRs as described herein, wherein the Mito-miR results in the down regulation of expression of one or more proteins, wherein the reduced expression of the protein in a tumor cell results in cell death. In one embodiment, the expression of one or more proteins selected from the group consisting of survivin, cyclin D1, cyclin B1, FKBP38, N-cadherin and caveolin is reduced by treatment with Mito-miRs or other isolated RNA molecules as described herein. Mito-miRs as described herein that can bind to UTR of, for example, survivin, cyclin D1 and cyclin B1 are shown in
[0142] a. Down Regulation of Survivin
[0143] Survivin is a member of the Inhibitor of Apoptosis (IAP) family of proteins, and is up-regulated in virtually all human cancer cells. The IAP family of proteins plays an important cytoprotective function in cancer cells downstream of the intrinsic apoptosis pathway (Dohi et al., J. Biol. Chem., 2004, 279:34087-34090; Dohi et al., Mol Cell., 2007, 27:17-28; Altieri, D. C., Biochem. J., 2010, 30:199-205; Kang et al., J. Biol. Chem., 2011, 286:16758-16767). Down regulation of survivin will affect this anti-apoptotic function, and result in apoptosis of cancer cells. As described herein, the level of survivin in tumor cells is drastically reduced by treatment with antisense oligonucleotide to ASncmtRNA (See Examples 12, 14), and treatment with miRNA or other isolated RNA molecules as described herein will similarly reduce survivin levels and kill cancer cells. Treatment with the isolated RNA molecules as described herein result in the binding of Mito-miRs such as those shown in
[0144] b. Down Regulation of Cyclin D1
[0145] Cyclin D1 is involved in the regulation of cell growth, and is known to be required for the transition of cells from phase G1 to S (Vien Khach Lai, et al., Cell Cycle, 11:767-777, 2012; Jing Nie, et al., Carcinogenesis, 33:220-225, 2012; Qiong Jiang et al., BMC Cancer, 9:194-208, 2009). The down regulation of cyclin D1 results in an increase of cells in phase G1 and an increase in cell death. As described herein, the level of cyclin D1 in tumor cells is reduced by treatment with antisense oligonucleotide to ASncmtRNA (See Example 15), and treatment with miRNA or other isolated RNA molecules as described herein will similarly reduce cyclin D1 levels and kill cancer cells. Treatment with the isolated RNA molecules as described herein result in the binding of Mito-miRs such as those shown in
[0146] c. Down Regulation of Cyclin B1
[0147] Cyclin B1 is involved in the regulation of cell growth, and is known to induce mitosis (Debra J. Wolgemuth, Cell Cycle, 7:3509-3513, 2008; Vera Huang and Long-Cheng Li, RNA Biology, 9:269-273, 2012). The down regulation of cyclin B1 results in the inhibition of mitosis and an increase in cell death. As described herein, the level of cyclin B1 in tumor cells is reduced by treatment with antisense oligonucleotide to ASncmtRNA (See Example 15), and treatment with miRNA or other isolated RNA molecules as described herein will similarly reduce cyclin B1 levels and kill cancer cells. Treatment with the isolated RNA molecules as described herein result in the binding of Mito-miRs such as those shown in
[0148] d. Down Regulation of FKBP38
[0149] Bcl2 is a mitochondrial anti-apoptotic protein that is maintained in the mitochondria by the action of FKBP38 (Portier, B. P. and Taglialatela, G., J. Biol. Chem., 281:40493-40502, 2006; Shirane, M. and Nakayama, K. I., Nat. Cell Biol., 5:28-37, 2003; Wang, H. Q., et al., Human Mol. Gen., 14:1889-1902, 2005; Bai X, et al., Science, 318:977-980, 2007; Xuemin Wang, et al., J. Biol. Chem., 283:30482-30492, 2008). The down regulation of FKBP38 results in the migration of Bcl2 to the nucleus, where it becomes pro-apoptotic, resulting in death of cancer cells. As described herein, the level of FKBP38 in tumor cells is reduced by treatment with antisense oligonucleotide to ASncmtRNA, without affecting the level of Bcl2 (See Example 16), and treatment with miRNA or other isolated RNA molecules as described herein will similarly reduce FKBP38 levels and kill cancer cells. Treatment with the isolated RNA molecules as described herein result in the binding of Mito-miRs, which can be complementary to a UTR of FKBP38 mRNA. Such Mito-miRNA molecules are selective in down regulating FKBP38, and are ideal for treatment of a variety of cancers without effecting normal cells.
[0150] e. Down Regulation of N-Cadherin and Caveolin
[0151] N-cadherin and caveolin are involved in cell migration, cell invasion and metastasis (L. D. M. Derycke and M. E. Bracken, Int. J. Dev. Biol., 4:463-476, 2004; Lorena Lobos-Gonzalez et al., Pigment Cell Melanoma Res., 26:555-570, 2013; Fiucci, G., et al., Oncogene 21:2365-2375, 2002; Jean-Leon Maitre and Carl-Philipp Heisenberg, Current Biology 23:R626-R633,2013). The down regulation of N-cadherin and caveolin results in increased possibilities of apoptosis and death of cancer cells. As described herein, the level of N-cadherin and caveolin in tumor cells is reduced by treatment with antisense oligonucleotide to ASncmtRNA (See Example 15), and treatment with miRNA or other isolated RNA molecules as described herein will similarly reduce N-cadherin and caveolin levels and kill cancer cells. Treatment with the isolated RNA molecules as described herein result in the binding of Mito-miRs, which can be complementary to a UTR of N-cadherin or caveolin mRNA. Such Mito-miRNA molecules are selective in down regulating N-cadherin and caveolin, and are ideal for treatment of a variety of cancers without effecting normal cells.
III. Methods of Treatment in Combination with Other Anticancer Therapies
[0152] In some aspects, any of the methods of treatment described herein can comprise administering one or more additional anticancer therapies to the subject. Various classes of anticancer agents can be used. Non-limiting examples include: alkylating agents, antimetabolites, anthracyclines, plant alkaloids, topoisomerase inhibitors, podophyllotoxin, antibodies (e.g., monoclonal or polyclonal), tyrosine kinase inhibitors (e.g., imatinib mesylate (Gleevec or Glivec)), hormone treatments, soluble receptors and other antineoplastics.
[0153] Topoisomerase inhibitors are also another class of anticancer agents that can be used. Topoisomerases are essential enzymes that maintain the topology of DNA. Inhibition of type I or type II topoisomerases interferes with both transcription and replication of DNA by upsetting proper DNA supercoiling. Some type I topoisomerase inhibitors include camptothecins: irinotecan and topotecan. Examples of type II inhibitors include amsacrine, etoposide, etoposide phosphate, and teniposide. These are semisynthetic derivatives of epipodophyllotoxins, alkaloids naturally occurring in the root of American Mayapple (Podophyllum peltatum).
[0154] Antineoplastics include the immunosuppressant dactinomycin, doxorubicin, epirubicin, bleomycin, mechlorethamine, cyclophosphamide, chlorambucil, ifosfamide. The antineoplastic compounds generally work by chemically modifying a cell's DNA.
[0155] Alkylating agents can alkylate many nucleophilic functional groups under conditions present in cells. Cisplatin and carboplatin, and oxaliplatin are alkylating agents. They impair cell function by forming covalent bonds with the amino, carboxyl, sulfhydryl, and phosphate groups in biologically important molecules.
[0156] Vinca alkaloids bind to specific sites on tubulin, inhibiting the assembly of tubulin into microtubules (M phase of the cell cycle). The vinca alkaloids include: vincristine, vinblastine, vinorelbine, and vindesine.
[0157] Anti-metabolites resemble purines (azathioprine, mercaptopurine) or pyrimidine and prevent these substances from becoming incorporated in to DNA during the S phase of the cell cycle, stopping normal development and division. Anti-metabolites also affect RNA synthesis.
[0158] Plant alkaloids and terpenoids are derived from plants and block cell division by preventing microtubule function. Since microtubules are vital for cell division, without them, cell division cannot occur. The main examples are vinca alkaloids and taxanes.
[0159] Podophyllotoxin is a plant-derived compound which has been reported to help with digestion as well as used to produce two other cytostatic drugs, etoposide and teniposide. They prevent the cell from entering the G1 phase (the start of DNA replication) and the replication of DNA (the S phase).
[0160] Taxanes as a group includes paclitaxel and docetaxel. Paclitaxel is a natural product, originally known as Taxol and first derived from the bark of the Pacific Yew tree. Docetaxel is a semi-synthetic analogue of paclitaxel. Taxanes enhance stability of microtubules, preventing the separation of chromosomes during anaphase.
[0161] In some aspects, the anticancer therapeutics can be selected from remicade, docetaxel, celecoxib, melphalan, dexamethasone (Decadron), steroids, gemcitabine, cisplatinum, temozolomide, etoposide, cyclophosphamide, temodar, carboplatin, procarbazine, gliadel, tamoxifen, topotecan, methotrexate, gefitinib (Iressa), taxol, taxotere, fluorouracil, leucovorin, irinotecan, xeloda, CPT-11, interferon alpha, pegylated interferon alpha (e.g., PEG INTRON-A), capecitabine, cisplatin, thiotepa, fludarabine, carboplatin, liposomal daunorubicin, cytarabine, doxetaxol, pacilitaxel, vinblastine, IL-2, GM-CSF, dacarbazine, vinorelbine, zoledronic acid, palmitronate, biaxin, busulphan, prednisone, bortezomib (Velcade), bisphosphonate, arsenic trioxide, vincristine, doxorubicin (Doxil), paclitaxel, ganciclovir, adriamycin, estrainustine sodium phosphate (Emcyt), sulindac, or etoposide.
[0162] In other embodiments, the anticancer therapeutics can be selected from bortezomib, cyclophosphamide, dexamethasone, doxorubicin, interferon-alpha, lenalidomide, melphalan, pegylated interferon-alpha, prednisone, thalidomide, or vincristine.
[0163] In other aspects, any of the methods of treatment described herein can include either autologous or allogenic stem cell transplantation therapy. Autologous stem cell transplantation is typically used for subjects under the age of 65 years who do not have substantial heart, lung, renal or liver dysfunction.

In some embodiments, the pharmaceutical composition comprises an isolated double stranded RNA molecule, wherein one strand of the double stranded RNA molecule consists of a sequence/corresponds to a RNA sequence selected from the group consisting of SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, SEQ ID NO:11, SEQ ID NO:12, SEQ ID NO:13, SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, and SEQ ID NO:19.
[0165] Also provided herein is a pharmaceutical composition comprising one or more isolated RNA molecules as described herein and a pharmaceutically acceptable vehicle or excipient.
[0166] The anticancer therapies, e.g. treatment by administering the isolated RNA molecules as disclosed herein, can be administered in the form of pharmaceutical compositions. These RNA molecules and pharmaceutical compositions thereof can be administered by a variety of routes including oral, rectal, cerebrospinal, transdermal, subcutaneous, topical, transmucosal, nasopharangeal, pulmonary, intravenous, intraperitonial, intramuscular, and intranasal. In some embodiments, the administration is a local administration. In some embodiments, the local administration is selected from the group consisting of administration into an organ, into a cavity, into a tissue, into a solid tumor, and subcutaneous administration. In some embodiments, the administration is systemic administration. In some embodiments, the systemic administration is intravenous or intraperitoneal administration. These compounds are effective as both injectable and oral compositions. Such compositions are prepared in a manner well known in the pharmaceutical art and comprise at least one active compound. When employed as oral compositions, the oligonucleotides and another disclosed herein are protected from acid digestion in the stomach by a pharmaceutically acceptable protectant.
[0167] Also provided herein are pharmaceutical compositions which contain, as the active ingredient, one or more of the isolated RNA molecules as disclosed herein associated with one or more pharmaceutically acceptable excipients or carriers. In making the compositions of this invention, the active ingredient is usually mixed with an excipient or carrier, diluted by an excipient or carrier or enclosed within such an excipient or carrier which can be in the form of a capsule, sachet, paper or other container. When the excipient or carrier serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders.
[0168] In preparing a formulation, it may be necessary to mill the active lyophilized compound to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it ordinarily is milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size is normally adjusted by milling to provide a substantially uniform distribution in the formulation, e.g. about 40 mesh.
[0169] Some examples of suitable excipients or carriers include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the invention can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art.
[0170] In another aspect, one or more RNA molecules or DNA molecules as described herein are encapsulated within a microcarrier for deliver to an individual. In some embodiments the microcarrier encapsulates more than one RNA molecule and/or DNA molecule species. In some embodiments, the one or more one RNA molecule and/or DNA molecule species encapsulated within the microcarrier comprises a nucleic acid sequence selected from the group consisting of SEQ ID NOs:7-32. Methods of encapsulating oligonucleotides in microcarriers are well known in the art, and described, for example, in International application WO98/55495. Colloidal dispersion systems, such as microspheres, beads, macromolecular complexes, nanocapsules and lipid-based system, such as oil-in-water emulsions, micelles, mixed micelles and liposomes can provide effective encapsulation of oligonocelotides within microcarrier compositions. The encapsulation composition may further comprise any of a wide variety of components. These include, but are not limited to, alum, lipids, phospholipids, lipid membrane structures (LMS), polyethylene glycol (PEG) and other polymers, such as polypeptides, glycopeptides, and polysaccharides.
[0171] The compositions can be formulated in a unit dosage form, each dosage containing from about 5 mg to about 1000 mg or more, such as any of about 5 mg to about 900 mg, 5 mg to about 800 mg, about 5 mg to about 700 mg, about 5 mg to about 600 mg, about 5 mg to about 500 mg, about 10 mg to about 500 mg, about 15 mg to about 500 mg, about 20 mg to about 500 mg, about 25 mg to about 500 mg, about 30 mg to about 500 mg, about 35 mg to about 500 mg, about 40 mg to about 500 mg, about 45 mg to about 500 mg, or about 50 mg to about 500 mg, inclusive, including any range in between these values, of the active ingredient. The term unit dosage forms refers to physically discrete units suitable as unitary dosages for subjects, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient or carrier.
[0172] The anticancer therapies disclosed herein are effective over a wide dosage range and are generally administered in a therapeutically effective amount. It will be understood, however, that the amount of the anticancer therapies actually administered will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual subject, the severity of the subject's symptoms, and the like.
[0173] For preparing solid compositions such as tablets, the principal active ingredient anticancer therapy is mixed with a pharmaceutical excipient or carrier to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.
[0174] The tablets or pills of the present invention can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action and to protect the anticancer therapies (such as an oligonucleotide) from acid hydrolysis in the stomach. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.
[0175] The liquid forms in which the novel compositions of the present invention can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as corn oil, cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.
[0176] Parenteral routes of administration include but are not limited to direct injection into a central venous line, intravenous, intramuscular, intraperitoneal, intradermal, or subcutaneous injection. Formulations suitable for parenteral administration (e.g., an RNA molecule as described herein in a microcarrier formulation) are generally formulated in USP water or water for injection and may further comprise pH buffers, salts bulking agents, preservatives, and other pharmaceutically acceptable excipients. RNA molecules or DNA molecules as described herein, for example as microcarrier complexes or encapsulates, for parenteral injection may be formulated in pharmaceutically acceptable sterile isotonic solutions such as saline and phosphate buffered saline for injection.
[0177] Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions can contain suitable pharmaceutically acceptable excipients as described herein. The compositions can be administered by the oral or nasal respiratory route for local or systemic effect. Compositions in pharmaceutically acceptable solvents can be nebulized by use of inert gases. Nebulized solutions can be inhaled directly from the nebulizing device or the nebulizing device can be attached to a face mask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can also be administered, orally or nasally, from devices which deliver the formulation in an appropriate manner.

ASO-1537S, having the sequence of 5-CACCCACCCAAGAACAGG (SEQ ID NO:36) and control antisense oligonucleotide (ASO-C) having the sequence of 5-AGGTGGAGTGGATTGGGG (SEQ ID NO:38) were synthesized by IDT or Invitrogen with 100% phosphorothioate linkages. Cells were seeded into a 12-well plate (Nunc) at 50,000 cells per well (HeLa, HFK) or 100,000 cells per well (SK-MEL-2) and transfected the next day with ASOs at 100 nM (HeLa, HFK) or 150 nM (SK-MEL-2) using 2.5 l, 2.0 l and 1.0 l Lipofectamine 2000 (Invitrogen) respectively for HeLa, SK-MEL-2 and HFK cells, according to the manufacturer's directions, or left untreated. Transfection was allowed to proceed under normal culture conditions, as well as an untreated control sample, with cells harvested at desired time points up to 48 hours.
[0183] Cells were harvested and the RNA extracted with TRIzol Reagent (Invitrogen) (Villegas et al., Nucleic Acids Res., 2007, 35:7336-7347; Burzio et al., Proc. Natl. Acad. Sci. U.S.A., 2009, 106:9430-9434; Villota et al., J. Biol. Chem., 2012, 287:21303-21315). The RNA preparations were treated with TURBO DNA-free (Ambion) to eliminate DNA contamination. Convention RT-PCR was carried out with 50-100 ng RNA, 50 ng random hexamers, 0.5 mM each dNTP, 5 mM DTT, 2 U/l Rnase-out (Invitrogen) and 200 U reverse 25 transcriptase (M-MLV, Invitrogen). Reactions were incubated at 25 C. for 10 minutes, 37 C. for 50 minutes and 65 C. for 10 minutes. PCR was carried out in 50 l containing 2 l cDNA, 0.4 mM each dNTP, 1.5 mM MgCl.sub.2, 2 U GoTaq (Promega) and 1 M each forward or reverse primer (ASncmtRNA-1 (AS-1), ASncmtRNA-2 (AS-2) and 18S as loading control). The primers used are provided in the following table.

Example 2: Inhibition of HeLa Cell Proliferation and Induction of HeLa Cell Death by Knockdown of ASncmtRNA with Antisense Oligonucleotide Complementary to the Loop Region of the ASncmtRNA
[0185] In this study, knockdown of expression of antisense non-coding chimeric mitochondrial RNA (ASncmtRNA) with antisense oligonucleotide 1537S (ASO-1537S) was shown to induce cell death in HeLa cells.
Materials and Methods
[0186] HeLa cells were cultured and transfected with ASO-C, ASO-1537S, ASO-1537S 5-Alexa Fluor 488, or untreated, as described in Example 1.
[0187] Triplicate samples of ASO-1537S, ASO-C or untreated cells were harvested at 24, 36 and 48 hours, and cells were counted to assess cell proliferation. Similarly treated cells were prepared in triplicate and harvested at 48 hours to assess cell proliferation using Click-iT EdU Alexa Fluor 488 Kit (Invitrogen), following a 2 hour EdU (5-ethynyl-2-deoxyuridine) pulse, according to manufacturer's directions. The cells were co-stained with DAPI to assess the total number of cells, where EdU incorporation was measured as EdU positive cells versus total cells. Samples treated with ASO-1537S 5-Alexa Fluor 488 labeled were harvested at 48 hours. Harvested cells with fluorescent marker were analyzed on an Olympus BX-51 fluorescence microscope. In another set of ASO-1537S, ASO-C and untreated cells, the cells were harvested at 48 hours and viewed on phase microscopy to assess cell detachment from substrate. In another study, ASO-1537S and ASO-C were transfected at 25, 50 and 100 nM along with untreated cells. The cells were harvested at 48 hours and stained with Trypan blue (Tb) and counted. The % Tb-positive cells indicated the amount of cell death.

TABLE-US-00002 nM l of Cell line ASO-1537S Lipofectamine SiHa; MDA-MB-231; MCF7; 100 2.5 DU145; H292; HUVEC HFK 100 1.0 PC3 100 2.0 SK-MEL-2; HREC 150 2.0 HepG2; U87; Caco-2 150 2.5 A498 150 4.0 HnEM 150 4.0 (Lipofectin) OVCAR-3 200 2.0
The cells were harvested at 24 hours and analyzed on an Olympus BX-51 fluorescence microscope.
Results
[0194] All cell lines demonstrated greater than 90% transfection of the cells at 24 hours post transfection.
Example 5: Treatment with ASO-1537S does not Affect Normal Cells
[0195] In this example, human umbilical vein endothelial cells (HUVEC), human renal epithelial cells (HREC) and human melanocytes (HnEM) cells were transfected with ASO-1537S and assessed by Trypan blue staining.
Materials and Methods
[0196] HUVEC cells were cultured in M199 media (Gibco) supplemented with 20% FCS, 50 g/ml heparin, 50 g/ml endothelial cell growth supplement (ECGS; Calbiochem) and Pen/Strep (50 U/ml penicillin, 50 g/ml streptomycin), HREC and HnEM were cultured as described in Example 4. HUVEC, HREC and HnEM cells were cultured at 50,000 cells per well and transfected with ASO-1537S or ASO-C as described in Example 3, or untreated, all in triplicate. At 48 hours post transfection, cells were harvested, stained with Trypan blue, and counted.

[0197] All of the ASO-1537S treated samples were comparable to control and untreated cells, with over 90% of cells Tb-negative, as seen in
Example 6: Mitochondrial Alterations and Apoptosis Induced by ASO-1537S
[0198] In this example, HeLa cells were treated with ASO-1537S and the mitochondrial membrane potential (m) was measured.
Materials and Methods
[0199] HeLa cells were cultured at 50,000 cells per well. To assess m, at 24 hours post transfection, loaded with 20 nM tetramethylrhodamine methyl ester (TMRM, Molecular Probes) for 15 minutes at 37 C., harvested and analyzed by flow cytometry on a BDS-FACS Canto Flow Cytometer. As a positive control, cells were treated with 10 M carbonyl cyanide 3-chlorophenylhydrazone for 30 minutes at 37 C. (CCCP, Sigma-Aldrich) prior to staining with TMRM. DU145, MDA-MB-231 and H292 cells were similarly assayed for m, transfecting as described in Example 4.
Results
[0200] The m of ASO-1537S treated samples was comparable to the positive control. Samples assayed in triplicate showed that ASO-1537S induced about 55% dissipation of m compared to 70% for CCCP and about 10-15% for control and untreated cells.
Example 7: Release of Cytochrome c from Mitochondria and Activation of Caspases
[0201] Dissipation of m induces the release of cytochrome c, followed by activation of caspases (Heerdt et al., Cancer Res., 66:1591-1596; Houston et al., Int. J. Cell Biol., 2011, article 978583; Gottlieb et al., Cell Death Differ., 2003, 10:709-717). In this study, HeLa cells treated with ASO-1537S or staurosporine (STP, apoptosis control) are assessed for the release of cytochrome c into the cytoplasm and for activation of caspases.
Materials and Methods
[0202] HeLa cells were cultured at 50,000 cells per well and transfected with 100 nM ASO-1537S or ASO-C as described in Example 1, treated with staurosporine, or untreated. After 24 hours, cells were harvested and washed in ice cold PBS, then centrifuged at 1000g for 10 minutes at room temperature. The pellets were suspended in Radio-Immunoprecipitation Assay buffer (RIPA; 10 mM Tris-HCl pH 7.4, 1% sodium deoxycholate, 1% Triton X-100, 0.1% sodium dodecyl sulfate), containing 1 mM PMSF and protease inhibitor cocktail (Sigma-Aldrich). Protein concentration was quantified with the Bradford microplate-system Gen5 EPOCH (BioTeK) and samples were analyzed by Western Blot. The samples were loaded at 30 g protein per lane on SDS-PAGE and transferred to polyvinylidine difluoride (PVDF) membranes. Membranes were probed with rabbit polyclonal antibodies against cytochrome c (Cell Signaling; 1:1000), with mouse monoclonal anti--actin (Sigma-Aldrich; 1:4000) as a loading control. Blots were revealed with peroxidase-labeled anit-mouse or anti-rabbit IgG (Calbiochem; 1:5000). The blots were detected with the EZ-ECL system (Biological Industries).
[0203] Similarly prepared samples were assayed for caspase activation, adding FITC-VAD-fmk (Promega) as a fluorogenic caspase inhibitor which binds to activated caspases (Garcia-Calvo et al., J. Biol. Chem., 1998, 273:32608-32613). In addition to STP treated control, cells are treated with 100 M H.sub.2O.sub.2 as a positive control for necrosis. The FITC-VAD-fmk was added after transfection, STP treatment, or H.sub.2O.sub.2 treatment at 10 M and incubated for 20 minutes at 37 C. Cells were harvested, washed in PBS and fixed in 3.7% p-formaldehyde for 15 minutes at room temperature, and fluorescent images were obtained. In order to confirm that caspase inactivation was involved in cell death, inhibition of apoptosis was carried out with the non-fluorescent caspase inhibitor z-VAD-fmk (Promega), added 2 hours prior to transfection or STP treatment at a concentration of 25 M for HeLa cells. Cell death was assayed by propidium iodide staining.
Results
[0204] The western blot analysis for the presence of cytochrome c showed that only those cells treated with ASO-1537S or STP had cytocrhome c in the cytosolic fraction (
Example 8: Measurement of Annexin V in ASO-1537S Treated HeLa Cells
[0205] In this experiment, the translocation of phosphatidylserine to the outer layer of the plasma membrane, which is an indication of apoptosis, was assessed. Phosphatidylserine on the surface of cells was detected by binding to fluorescent labeled Annexin V.
Materials and Methods
[0206] HeLa cells were transfected with ASO-1537S, ASO-C, STP or untreated and cultured as described in Examples 1 and 7. After 24 hours post treatment, cells were labeled with Annexin V-Alexa fluor 488 (APOtarget kit, Invitrogen) according the manufacturer's directions, and stained with propidium iodide.
Results
[0207] Annexin V positive cells were observed for both the STP and ASO-1537S treated cells. The % Annexin V positive cells are shown in

[0208] In this experiment, DNA fragmentation is measured by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL assay) in cancer cell lines of MCF7 (breast carinoma), PC3 (prostate carcinoma), HepG2 (hepatoma), Caco-2 (colon carcinoma), U87 (glioblastoma), SiHa, MDA-MB-231, DU145, SK-MEL-2, A498, OVCAR-3 and HeLa and in normal cell line HFK.
Materials and Methods
[0209] Cell lines were transfected with ASO-C, ASO-1537S or untreated and cultured as described in Example 4. HeLa and HFK cells were also treated with Dnase I as a positive control. After 48 hours, cells were harvested, fixed, and subjected to TUNEL assay. The samples were evaluated using Dead End Fluorometric TUNEL kit (Promega) according to the manufacturer's directions, resulting in fluorscein-12-dUTP labeling of fragmented nucleic acid. Cells were also stained with propidium iodide (PI) or 4,6-diamidino-2-phenylindole (DAPI) to distinguish the cells labeled by the TUNEL assay from unlabeled cells.

[0212] HeLa or HFK cell lines were transfected with ASO-C, ASO-1537S, or untreated and cultured at 100,000 cells per well. HeLa and HFK cells were also treated with STP at a concentration of 5 M as a positive control for apoptosis. After 24 hours (HeLa) or 48 hours (HFK), cells were harvested, centrifuged at 600g for 5 minutes and the pellets were suspended in 100% ethanol and stored at 20 C. for 24 hours. Cells were then treated with 1 mg/ml Rnase A for 1 hour at room temperature. The cells were stained with PI and assessed by Flow Cytometry.

Materials and Methods
[0215] SK-MEL-2, OVCAR-3, HeLa and SiHa were transfected with ASO-C, ASO-1537S or untreated and cultured as described in Example 4. Cells were harvested after 48 hours, counted and seeded in 12-well plates on soft agar in triplicate, with 200 cells per well for HeLa and SiHa, 500 cells per well for OVCAR-3 and 2000 cells per well for SK-MEL-2, as determined by Trypan blue exclusion.

Example 12: Down Regulation of Survivin in ASO-1537S Treated SK-MEL-2 Cells
[0217] In this experiment, ASO-1537S treated, control treated or untreated SK-MEL-2 cells are assessed for survivin expression by western blot analysis.
Materials and Methods
[0218] SK-MEL-2 were transfected with 150 nM of ASO-C or ASO-1537S or untreated and cultured for 24 hours as described in Example 4. Harvested cells were processed for western blot analysis as described in Example 7, using an antibody against survivin (rabbit polyclonal; R&D systems; 1:1000). This was repeated in triplicate and bands were quantitated by measuring pixel intensity of each band using ImageJ software (NIH), normalized to -actin levels as loading control. Additional samples were prepared for ASO-1537S treated cells and harvested at 3, 8, and 22 hours post transfection, and the survivin level was assessed relative to an untreated control.
[0219] To assess whether the survivin down regulation was due to proteosomal degradation, SK-MEL-2 cells were transfected with ASO-1537S or ASO-C with or without treatment with 26S proteosome inhibitor MG132 (Lin et al., J. Biol. Chem., 283:21074-21083, 2008). To assess whether survivin was degraded by activated caspases (Igarashi et al., Nucleic Acids Res., 35:D546-9, 2007), SKMEL-2 cells were transfected with ASO-1537S or ASO-C with or without the caspase inhibitor z-VAD-fmk.

[0221] In this experiment, the relative level of mRNA in cells treated with ASO-1537S was compared to control treated SK-MEL-2 cells.
Materials and Methods
[0222] SK-MEL-2 were transfected with 150 nM of ASO-C or ASO-1537S or untreated and assessed by RT-PCR. cDNA was synthesized with the Affinity Script QPCR cDNA Synthesis Kit (Agilent Technologies) using 500 ng RNA and 250 ng random hexamers (Invitrogen). Reactions were incubated 10 minutes at 25 C., 1 hour at 45 C. and 5 minutes at 95 C. RNase H (2U) was added and samples were incubated at 37 C. for 20 minutes.

Example 15: Down Regulation of Other Proteins in SK-MEL-2 Cells Treated with ASO-1537S or ASO-226S
[0227] In this experiment, SK-MEL-2 cells were treated with ASO-1537S, ASO-226S (complementary to the 3 single-stranded region of the ASncmtRNA), ASO-C or untreated and levels of Cyclin D1, Cyclin B1, N-cadherin and caveolin were assessed by western blot analysis. Cyclin D1 is required for transition of cells from phase G1 to S, and reduction of Cyclin D1 levels results in increase in G1 phase cells. Cyclin B1 is a known inductor of mitosis, and inhibition of mitosis leads to arrest in G2 phase of the cycle and increased cell death. N-cadherin and caveolin are involved in cell migration, cell invasion and metastasis, and their down regulation inhibits these cancer cell properties.
Materials and Methods
[0228] ASO-226S having the sequence of 5-TAAGACCCCCGAAACCAGAC (SEQ ID NO:45) was synthesized with 100% phosphorothioate linkages (IDT or Invitrogen or Biosearch Inc.). SK-MEL-2 cells were transfected with 150 nM of ASO-C, or ASO-1537S, or untreated and cultured for 24 hours as described in Example 4. Cyclin B1 was also assessed in cells transfected with ASO-226S. Harvested cells were processed for western blot analysis as described in Example 7, using an antibody against cyclin D1 (monoclonal; BC PHarmagen; 1:250), cyclin B1 (monoclonal; BD Pharmagen; 1:500), N-cadherin (rabbit polyclonal; Thermo Scientific; 1:1000), or caveolin (rabbit polyclonal; Abcam; 1:1000). Each was repeated in triplicate and bands were quantitated by measuring pixel intensity of each band using ImageJ software (NIH), normalized to -actin levels as loading control.

Example 16: Effects of Treatment of SK-MEL-2 and PC3 Cells with ASO-1537S or ASO-226S on Levels of Bcl-2 and FKBP38
[0230] In this experiment, SK-MEL-2 and PC3 cancer cell lines were treated with ASO-1537S or ASO-226S and levels of Bcl-2 and FKBP38 were assessed by western blot analysis. Bcl-2 is a mitochondrial anti-apoptotic protein that is kept in the mitochondria by the action of FKBP38. A reduction in the expression of FKBP38 results in the migration of Bcl-2 to the nucleus where it becomes pro-apoptotic.
Materials and Methods
[0231] SK-MEL-2 and PC3 cells were transfected with ASO-C, ASO-226S or ASO-1537S or untreated and cultured for 24 hours as described in Example 4. Harvested cells were processed for western blot analysis as described in Example 7, using an antibody against Bcl-2 (rabbit polyclonal; Abcam; 1:1000) or FKBP38 (rabbit monoclonal; Abcam; 1:1000).

Example 17: Down Regulation of Survivin and Cell Death in ASO-1537S Treated Cells is Dependent on RNase H
[0233] In this experiment, cell proliferation, knockdown of ASncmtRNAs (AS-1 or AS-2) and survivin levels were assessed for SK-MEL-2 cells treated with ASO-1537S or ASO-C and compared to cells treated with peptidic nucleic acid (PNA) analogs of ASO-1537S and ASO-C.
Materials and Methods
[0234] SK-MEL-2 were transfected with 150 nM of ASO-C or ASO-1537S, PNA analogs of ASO-C and ASO-1537S or untreated. At 24 hours post transfection, cells were harvested and counted, or stained with Trypan blue (see Example 2), ASncmtRNA (AS-1, AS-2) levels were assessed by RT-PCR (see Example 1), or assessed for survivin levels by western blot analysis (see Example 12).

Example 18: Binding of Dicer to ASncmtRNA-1 and ASncmtRNA-2 in SK-MEL-2 Cells
[0236] In this experiment, the cytosolic fraction of SK-MEL-2 cells are immunoprecipitated with a Dicer-specific monoclonal antibody. RNA is extracted from the immunoprecipitate and RT-PCR amplification is used to assess the level of ASncmtRNA.
Materials and Methods
[0237] SK-MEL-2 cells, 210.sup.7, were washed in 10 ml of ice cold sterile PBS, scraped, and sedimented at 300g for 5 minutes at 4 C. The cells were lysed in 100 l of RIP lysis buffer containing 0.5 l of protease inhibitor and 0.25 l of RNase inhibitor (MagnaRIP kit, Merck Millipore). An aliquot of 10 ml of each lysate was stored at 80 C. for use as input sample. A 100 l sample of lysate was mixed with 900 l of a suspension of magnetic beads, previously loaded with 5 g of anti-Dicer monoclonal antibody (Abcam) or polyclonal anti-SNRNP70 or control mouse or rabbit IgG (MagnaRIP kit). The samples were incubated at room temperature for 30 minutes with rotation, followed by four hours at 4 C. with rotation. RNA/protein complexes were removed by magnetic separation and washed in 500 l IP wash buffer, followed by 5 washes in RIP wash buffer. The recovered immunoprecipitates and input sample were incubated at 55 C. for 30 minutes in 150 l proteinase K buffer (RIP wash buffer containing 1% SDS and 1.8 mg/ml proteinase K) under constant agitation. The magnetic beads were separated and supernatants were transferred to a different tube. A 250 l aliquot of RIP wash buffer was added to the supernatant, followed by 400 l phenol:chloroform:isoamyl alcohol (125:24:1, pH 4.5) with mixing. The samples were centrifuged at 21,000g for 10 minutes at room temperature. The aqueous phase was removed and 300 l was mixed with 50 l of salt solution I, 15 l of salt solution II, 5 l of precipitate enhancer (along with salts all part of MagnaRIP kit) and 850 l of ethanol. The RNA was allowed to precipitate overnight at 4 C. and recovered by centrifugation at 21,000g for 30 minutes at 4 C. The pellet was washed twice in ice cold 70% ethanol, followed by entrifugation at 21,000g for 15 minutes at 4 C. The RNA pellet was suspended in nuclease-free water and a 60 ng sample was amplified by RT-PCR as described in Example 1, with U1 snRNA control amplification using the primers supplied in the MagnaRIP kit. The primers used for amplification of AS-1 and AS-2 were as follows:
TABLE-US-00004 AS-1 Forward 5-TAGGGATAACAGCGCAATCCTATT (SEQIDNO:39) Reverse 5-ACCCACCCAAGAACAGG (SEQIDNO:42) AS-2 Forward 5-GAACTCGGCAAACCTTACC (SEQIDNO:55) Reverse 5-ACCCACCCAAGAACAGG (SEQIDNO:42)

Example 19: Mito-miR Generated by Dicer Cleavage of the Double Stranded Region of ASncmtRNA in Silico
[0239] In this example, the resulting double stranded region of ASncmtRNA remaining after putative cleavage of ASO/ASncmtRNA by RNase H, followed by 5-3 exonuclease cleavage is further cleaved by Dicer.
Materials and Methods
[0240] The ASncmtRNA can be applied to modeling to generate approximately 22 base pair fragments as putative miRs resulting from Dicer cleavage (Park et al., Nature, 475:201-205, 2011). Using blastn alignment, TargetSCan (Lewis et al., Cell, 120:15-20, 2005) and miRbase (Griffiths-Jones et al., Nucleic Acids Res., 36:D154-158, 2008; Kozomara et al., Nucleic Acids Res., 39:D152-D157.37, 2011), putative fragments were identified.

Example 20: Knock Down of ASncmtRNA Results in Inhibition of Expression of Survivin Protein
[0242] This example shows that knocking down the ASncmtRNA induces miRNAs that interact with the 3 UTR of survivin mRNA, inhibiting the expression of the protein.
Materials and Methods
[0243] The 3 UTR of the survivin mRNA was amplified by RT-PCR on total SK-MEL-2 cell RNA, using forward primer 3 UTR of survivin. The mRNA was RT-PCR-amplified from total RNA of the SK-MEL-2 cells using the following primers:
TABLE-US-00005 Forward 5-AAAAAATCTAGACTT-GTTTTGTCTTG AAAGTGGCACCAG(SEQIDNO:37) Reverse 5-AAAAAATCTAG-AGCACCACTTCCAGG GTTTATTCC(SEQIDNO:56)
This was cloned into a unique XbaI site downstream of the firefly luciferase ORF of the pmiRGLO dual-luciferase vector (Promega) (
[0244] SK-MEL-2 cells were plated into 12-well plates (Nunc) at a density of 50,000 cells/well. The following day, cells were transfected with pmiRGLO vector containing the survivin 3 UTR (
