Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a liver cancer related specific siRNA and high efficiency double-stranded oligo RNA molecules containing the same. The double-stranded oligo RNA molecules have a structure in which hydrophilic and hydrophobic compounds are conjugated to both ends of the double-stranded RNA molecules by a simple covalent bond or a linker-mediated covalent bond in order to be efficiently delivered into cells and may be converted into nanoparticles in an aqueous solution by hydrophobic interactions of the double-stranded oligo RNA molecules. The siRNA contained in the double-stranded oligo RNA molecules may be preferably liver cancer related genes, particularly ZBTB7A, YAP1 or CHD1L, specific siRNA. 
         [0002]    In addition, the present invention relates to a method of preparing the double-stranded oligo RNA molecules, and a pharmaceutical composition for preventing or treating cancer, particularly, liver cancer, containing the double-stranded oligo RNA molecules. 
       BACKGROUND ART 
       [0003]    A technology of suppressing expression of genes is an important tool in developing a therapeutic agent for treating diseases and validating a target. Among these technologies, since roles of RNA interference (hereinafter, referred to as ‘RNAi’) was found, it was found that the RNAi acts on sequence-specific mRNA in various kinds of mammalian cells (Silence of the Transcripts: RNA Interference in Medicine, J. Mol. Med. 83: 764-773, 2005). When long-chain double-stranded RNA is delivered into cells, the delivered double stranded RNA is converted into a small interfering RNA (hereinafter, referred to as ‘siRNA’) processed into 21 to 23 base pairs (bp) by endonuclease called Dicer, wherein the siRNA is bound to a RNA-induced silencing complex (RISC), and then a guide (antisense) strand recognizes and degrades the target mRNA, such that the siRNA sequence-specifically inhibits expression of the target gene (Nucleic-Acid Therapeutics: Basic Principles and Recent Applications, Nature Reviews Drug Discovery 1: 503-514, 2002). 
         [0004]    According to Bertrand et al., it was found that the siRNA has a more excellent effect of inhibiting expression of the mRNA in vivo and in vitro as compared to antisense oligonucleotide (ASO) on the same target genes (Comparison of Antisense Oligonucleotides and siRNAs in Cell Culture and in Vivo, Biochem. Biophys. Res. Commun, 296: 1000-1004, 2002). In addition, since action mechanism of the siRNA is that the siRNA is complementarily bound to the target mRNA to sequence-specifically control the expression of the target genes, the target to which the siRNA may be applied may be remarkably enlarged as compared to the existing antibody based drugs or small molecule drugs (Progress towards in Vivo Use of siRNAs, Molecular Therapy 13(4): 664-670, 2006). 
         [0005]    In spite of excellent effects and various uses of the siRNA, in order to develop the siRNA as a therapeutic agent, the siRNA should be effectively delivered into a target cell by improving stability of the siRNA in vivo and cell delivery efficiency (Harnessing in vivo siRNA delivery for drug discovery and therapeutic development, Drug Discov. Today 11(1-2): 67-73, January 2006). 
         [0006]    In order to solve the above-mentioned problem, research into a technology of modifying some nucleotides or a backbone of the siRNA for improving the stability in vivo so as to have resistance against nuclease or using a carrier such as a viral vector, liposome, nanoparticles, or the like, has been actively conducted. 
         [0007]    In a delivery system using the viral vector such as adenovirus, retrovirus, or the like, transfection efficiency is high, but immunogenicity and oncogenicity are also high. On the other hand, a non-viral delivery system including nanoparticles has low cell delivery efficiency as compared to the viral delivery system but has advantages in that the non-viral delivery system may have high stability in vivo, be target-specific delivered, improve delivery efficiency through uptake or internalization of RNAi oligonucleotide contained therein into cell or tissues, or the like, and does not almost cause cytotoxicity and immune stimulation, such that currently, the non-viral delivery system has been evaluated as a potential delivery system as compared to the viral delivery system (Nonviral Delivery of Synthetic siRNA in vivo, J. Clin. Invest., 117(12): 3623-3632, Dec. 3, 2007). 
         [0008]    Among the non-viral delivery systems, in a method of using nanocarrier, nanoparticles are formed by using various polymers such as liposome, a cationic polymer complex, and the like, and then iRNA is supported on these nanoparticles, that is, nanocarriers to thereby be delivered into the cell. In the method of using the nanocarrier, a polymeric nanoparticle, polymer micelle, lipoplex, and the like, are mainly used. Among them, the lipoplex is composed of cationic lipid and interacts with anionic lipid of endosome in the cell to destabilize the endosome, thereby serving to deliver the iRNA into the cell (Proc. Natl. Acad. Sci. 15; 93(21): 11493-8, 1996). 
         [0009]    In addition, it was known that the efficiency of the siRNA in vivo may be increased by conjugating chemical compound, or the like, to an end site of a passenger (sense) strand of the siRNA to allow the siRNA to have improved pharmacokinetic features (Nature 11; 432(7014): 173-8, 2004). In this case, the stability of the siRNA may be changed according to the property of the chemical compound conjugated to the end of the sense (passenger) or antisense (guide) strand of the siRNA. For example, siRNA conjugated with a polymer compound such as polyethylene glycol (PEG) interacts with an anionic phosphoric acid group of the siRNA in a presence of cationic compound to form a complex, thereby obtaining a carrier comprising improved siRNA stability (J. Control Release 129(2): 107-16, 2008). Particularly, since micelles made of a polymer complex have significantly uniform distribution and a structure spontaneously formed while comprising significantly small sizes as compared to microsphere, nanoparticles, or the like, which is another system used as a drug delivery carrier, there are advantages in that quality of a product may be easily managed and reproducibility may be easily secured. 
         [0010]    Further, in order to improve intracellular delivery efficiency of the siRNA, a technology for securing stability of the siRNA and implementing efficient cell membrane permeability using a siRNA conjugate obtained by conjugating a hydrophilic compound (for example, polyethylene glycol (PEG)), which is a biocompatible polymer, to the siRNA via a simple covalent bond or a linker-mediated covalent bond has been developed (Korean Patent Registration No. 883471). However, even though the siRNA is chemically modified and conjugated to polyethylene glycol (PEC), disadvantages such as low stability in vivo and difficulty in delivering the siRNA into a target organ still remains. In order to solve these disadvantages, double-stranded oligo RNA molecules in which hydrophilic and hydrophobic compounds are bound to oligonucleotide, particularly, double-stranded oligo RNA such as siRNA have been developed. The molecules form self-assembled nanoparticles (which is referred to as self-assembled micelle inhibitory RNA (SAMiRNA™)) by hydrophobic interaction of the hydrophobic compound (See Korean Patent Registration No. 1224828). A SAMiRNA™ technology has advantages in that homogenous nanoparticles comprising significantly small sizes as compared to the existing delivery technologies may be obtained. 
         [0011]    Meanwhile, one in four Koreans die due to cancer (first cause of death), and in accordance with the development of a diagnostic method and a date collecting method, aging population, environmental changes, and the like, the number of patients die due to cancer is significantly increased every year. In addition, generation of cancer and death due to cancer has also been increased in the world, such that a technology of preventing, diagnosing, and treating cancer is a common and urgent task for people (Bio-Technology (BT) Trends Report, Current Development Trend of New Drug for Major Diseases, Biotechnology Policy Research Center, 2007, Edition No. 72). 
         [0012]    Cancer is one of the diseases resulting in death to the largest number of people around the world, and the development of an innovative cancer therapeutic agent may decrease medical expenses consumed at the time of treating cancer and create high added-value. Therapy of cancer is divided into surgery, radiation therapy, chemotherapy, and biological therapy. Among them, chemotherapy is a therapeutic method of suppressing proliferation of cancer cells or killing the cancer cells using a small molecule drug. Since much of the toxicities expressed by an anticancer drug are shown in normal cells, the anticancer drug has toxicity at some degree. In addition, the anticancer drug has resistance in that the drug has an anticancer effect but loses the anticancer effect after the drug is used for a constant period. Therefore, development of an anticancer drug capable of selectively acting on cancer cells and not generating resistance has been urgently demanded (Current Status of Conquering Cancer. BioWave 6 (19), 2004). Recently, development of a new anticancer drug target molecular features of cancer by securing molecular genetic information on cancer has been conducted, and it was reported that drug resistance is not generated in anticancer drugs targeting a specific molecular target. Therefore, a therapeutic agent comprising excellent effects and reducing adverse effects as compared to the existing anticancer drug may be developed by developing a gene therapeutic agent targeting the specific molecular target which only cancer cells have. 
         [0013]    After it was known that expression of genes may be specifically and efficiently inhibited using a RNA interference phenomenon, research into siRNAs targeting various genes has been conducted as a therapeutic drug for cancer. Examples of these genes may include oncogene, an anti-apoptotic molecule, telomerase, growth factor receptor gene, signaling molecule, and the like, the research is mainly conducted toward inhibiting expression of genes required for survival of cancer cells or inducing apotosis (RNA Interference in Cancer, Biomolecular Engineering 23: 17-34, 2006). 
         [0014]    ZBTB7A (zinc finger and BTB domain containing 7A) is proto-oncogene belonging to POK (POZ and Krüppel) known as transcription inhibitor. ZBTB7A is known to specifically inhibit transcription of ARF (alternate reading frame of the INK4a/ARF locus (CDKN2A)) which is tumor suppressor gene, and inactivate p53 indirectly (Won-II Choi et al. (2009) Proto-oncogene FBI-1 Represses Transcription of p21CIP1 by Inhibition of Transcription Activation by p53 and Sp1. THE JOURNAL OF BIOLOGICAL CHEMISTRY 284(19):12633-12644). 
         [0015]    In other words, as a master controller of ARF-Hdm2-p53-p21 pathway, the ZBTB7A influences p21, cell cycle arrest factor, by inhibiting upstream regulator in transcription or expression (translational) level. Thus the ZBTB7A accelerates cell proliferation, increases significantly the number of cells in S phase. In addition, the ZBTB7A is abnormally overexpressed solid tumors, including liver cancer (FBI-1 promotes cell proliferation and enhances resistance to chemotherapy of hepatocellular carcinoma in vitro and in vivo. Cancer [2012, 118(1):134-146). 
         [0016]    YAP1 (Yes-associated protein 1) was known to be binding to SH3 domain of Src protein tyrosine-kinase (Sudol M (1994) Yes-associated protein (YAP65) is a proline-rich phosphoprotein that binds to the SH3 domain of the Yes proto-oncogene product. Oncogene 9: 2145-2152). The YAP1 is potential oncogene overexpressed in various human cancers, and one of main effector of Hippo tumor inhibition pathway (Pan D (2010), The hippo signaling pathway in development and cancer. Dev Cell 19: 491-505). The YAP1 acts as co-activator with TEAD transcription factor in transcription process, and increases expression of genes which facilitate cell proliferation and inhibit apoptosis (Zhao B, Kim J, Ye X, Lai Z C, Guan K L (2009) Both TEAD-binding and WW domains are required for the growth stimulation and oncogenic transformation activity of yes-associated protein. Cancer Res 69: 1089-98). The Hippo tumor suppression pathway, downstream effector of YAP is known to be associated with CREB (cAMP response element-binding protein) in liver cancer formation (Mutual interaction between YAP and CREB promotes tumorigenesis in liver cancer. Hepatology. 2013 Mar. 26). 
         [0017]    CHD1L (1-like Chromodomain-helicase-DNA-binding protein) is known to be related to the chromatin remodeling and DNA relaxation process required for DNA replication, repair and transcription (Poly(ADP-ribose)-dependent regulation of DNA repair by the chromatin remodeling enzyme ALC1. Science. 2009 Sep. 4; 325(5945):1240-3). The CHD1L, also known as ALC1 (amplified in liver cancer 1) is frequently amplified and overexpressed in liver cancer (human hepatocelluar carcinoma, HCC). In addition, overexpression of CHD1L facilitates transition of G1/S phase in cell cycle, cell proliferation by reducing p53 expression, and inhibits apoptosis (Isolation and characterization of a novel oncogene, amplified in liver cancer 1, within a commonly amplified region at 1q21 in hepatocellular carcinoma. Hepatology. 2008 February; 47(2): 503-10). 
         [0018]    As described above, possibilities of ZBTB7A, YAP1 and CHD1L as targets for anti-cancer drug are known, but development of a siRNA therapeutic agent for ZBTB7A, YAP1 or CHD1L and a technology of delivering the siRNA therapeutic agent is still insignificant. Therefore, a need for the siRNA therapeutic agent capable of specifically and efficiently inhibiting expression of ZBTB7A, YAP1 or CHD1L and the technology of delivering the siRNA therapeutic agent is significant in the market.

         [0030]    Since the ZBTB7A, YAP1 or CHD1L specific siRNA provided in the present invention has a base sequence designed so as to be complementarily bound to mRNA encoding a gene corresponding thereto, the ZBTB7A, YAP1 or CHD1L specific siRNA may effectively suppress the expression of the corresponding gene. In addition, the ZBTB7A, YAP1 or CHD1L specific siRNA may include an overhang, which is a structure comprising one or at least two unpaired nucleotides at a 3′-end of the siRNA, 
         [0031]    and in order to improve the stability of the siRNA in vivo, the ZBTB7A, YAP1 or CHD1L specific siRNA may include various modifications for imparting resistance against nuclease and decreasing non-specific immune reactions.

         [0032]    The ZBTB7A, YAP1 or CHD1L specific siRNA provided in the present invention may significantly inhibit expression of corresponding proteins in addition to inhibiting expression the corresponding gene. Further, since it was known that the siRNA may improve sensitivity of radiation therapy or chemotherapy, which is a therapeutic method typically combined with a cancer-specific RNAi used to treat cancer (The Potential RNAi-based Combination Therapeutics.

         [0035]    In the case in which the hydrophilic and hydrophobic compounds are bound to the siRNA as described above, self assembled nanoparticles are formed by the hydrophobic interaction of the hydrophobic compound (See Korean Patent Registration No. 1224828). This conjugate has significantly excellent delivery efficiency into the body and excellent stability in vivo, and uniformity of particles sizes is excellent, such that quality control (QC) may be easy.

         [0054]    most preferably the siRNA according to the present invention may have a sense strand of the ZBTB7A specific siRNA comprising a sequence of the SEQ ID NO. 4, a sense strand of the YAP1 specific siRNA comprising a sequence of the SEQ ID NO. 118, or a sense strand of the CHD1L specific siRNA comprising a sequence of the SEQ ID NO. 204. 
         [0055]    Meanwhile, tumor tissue is significantly rigid and has diffusion-limitation as compared with normal tissue. Since this diffusion-limitation has a negative influence on movement of nutrients required for tumor growth, oxygen, waste materials such as carbon dioxide, the tumor tissue overcomes this diffusion-limitation by forming a blood vessel therearound through angiogenesis. The blood vessel generated through the angiogenesis in the tumor tissue may be a leaky and defective blood vessel comprising a leak of 100 nm to 2 um according to a kind of cancer. Therefore, the nanoparticles may easily pass through capillary endothelium of the cancer tissue comprising the leaky and defective structure as compared to organized capillary vessels of the normal tissue, such that the nanoparticles may easily approach the tumor interstitium during a circulation process in a blood vessels, and lymphatic drainage does not exist in the tumor tissue, such that drugs may be accumulated, which is called an ‘enhanced permeation and retention (EPR) effect’. Nanoparticles are tumor tissue-specifically delivered by this effect, which is referred to as ‘passive targeting’ (Nanoparticles for Drug Delivery in Cancer Treatment, Urol. Oncol., 26(1): 57-64, January-February, 2008). Active targeting means that a targeting moiety is bound to nanoparticles, and it was reported that the targeting moiety promotes preferential accumulation of the nanoparticles in the target tissue or improves internalization of the nanoparticles into the target cells (Does a Targeting Ligand Influence Nanoparticle Tumor Localization or Uptake Trends, Biotechnol. 26(10): 552-8m October, 2008, Epub. Aug. 21, 2008). In the active targeting, a target cell-specific material or a material, that is, the target moiety, capable of binding to over-expressed carbohydrate, receptor, or antigen is used (Nanotechnology in Cancer Therapeutics: Bioconjugated Nanoparticles for Drug Delivery, Mol. Cancer Ther., 5(8): 1909-1917, 2006). 
         [0056]    Therefore, in the case in which the targeting moiety is provided in the double-stranded oligo RNA molecules containing ZBTB7A, YAP1 or CHD1L specific siRNA according to the present invention and the nanoparticles formed therefrom, delivery of the siRNA into the target cell may be efficiently promoted, such that the siRNA may be delivered into the target cell even at a relatively low concentration to thereby exhibit a high target gene expression regulatory function and prevent the ZBTB7A, YAP1 or CHD1L specific siRNA from being non-specifically delivered to other organs or cells. 
         [0057]    Accordingly, the present invention provides double-stranded oligo RNA molecules in which a ligand L, particularly, a ligand specifically bound to a receptor promoting the internalization into the target cell through receptor-mediated endocytosis (RME) is additionally bound to the molecules represented by Structural Formulas (1) to (3), and a form in which the ligand is bound to the double-stranded RNA molecules represented by Structural Formula (1) has a structure of the following Structural Formula (4). 
         [0000]      (L i -Z j )-A-X—R—Y—B  Structural Formula (4)
 
         [0058]    In Structural Formula (4), A, B, X, and Y have the same definitions as those in Structural Formulas (1) to (3), respectively, L is a ligand specifically bound to the receptor promoting the internalization into the target cell through receptor-mediated endocytosis (RME), and i and j each are independently 0 or 1. 
         [0059]    Preferably, the ligand in Structural Formula (5) may be selected from a target receptor-specific antibody, aptamer, and peptide that have a receptor-mediated endocytic (REM) effect of target cell specifically promoting internalization; and chemicals, for example, folate (generally folate and folic acid are compatible with each other, and folate in the present invention means natural folate or active folate in the body), hexoamine such as N-acetyl galactosamine (NAG), sugars such as glucose, mannose, or the like, carbohydrate, or the like, but is not limited thereto.

         [0065]    (4) synthesizing a RNA single strand comprising a sequence complementary to that of the RNA single strand;

         [0067]    (6) preparing double-stranded oligo RNA molecules from the prepared RNA-polymer molecules and the RNA single strand comprising the complementary sequence through annealing. 
         [0068]    When the preparation is completed after step (5), whether or not the desired RNA-polymer molecules and the RNA single strand are prepared may be confirmed by measuring molecular weights of the purified RNA-polymer molecules and the RNA single strand using a MALDI-TOF mass spectrometer. In the method, the synthesizing (step (4)) of the RNA single strand comprising the sequence complementary to that of the RNA single strand prepared in step (2) may be performed before step (1) or in any one step of step (1) to step (5). 
         [0069]    In addition, the RNA single strand comprising the sequence complementary to that of the RNA single strand synthesized in step (2) may be used in a form in which a phosphate group is bound to the 5′-end. 
         [0070]    Meanwhile, there is provided a method of preparing ligand bound-double stranded oligo RNA molecules in which a ligand is additionally bound to the double stranded oligo RNA molecules containing ZBTB7A, YAP1 or CHD1L specific siRNA according to the present invention. 
         [0071]    The method of preparing the ligand bound-double-stranded oligo RNA molecules containing the ZBTB7A, YAP1 or CHD1L specific siRNA, for example, may include: 
         [0072]    (1) binding a hydrophilic compound to a solid support (CPG) to which a functional group is bound; 
         [0073]    (2) synthesizing a RNA single strand onto the solid support (CPG) to which the functional group-hydrophilic compound is bound; 
         [0074]    (3) covalently binding a hydrophobic compound to a 5′-end of the RNA single strand; 
         [0075]    (4) synthesizing a RNA single strand comprising a sequence complementary to that of the RNA single strand; 
         [0076]    (5) separating functional group-RNA-polymer molecules and the RNA single strand comprising complementary sequence from the solid support (CPG) after synthesizing is completed; 
         [0077]    (6) binding a ligand to an end of the hydrophilic compound using the functional group to prepare a ligand-RNA-polymer molecule single strand; and 
         [0078]    (7) preparing ligand-double-stranded RNA-polymer molecules from the prepared ligand-RNA-polymer molecules and the RNA single strand comprising the complementary sequence through annealing. 
         [0079]    When the preparation is completed after step (6), the ligand-RNA-polymer molecules and the RNA single strand comprising the complementary sequence are separated and purified. Then, whether or not the desired ligand-RNA-polymer molecules and the complementary RNA are prepared may be confirmed by measuring molecular weights of the purified RNA-polymer molecules and the RNA single strand using the MALDI-TOF mass spectrometer. The ligand-double-stranded oligo RNA-polymer molecules may be prepared from the prepared ligand-RNA-polymer molecules and the RNA single strand comprising the complementary sequence through annealing. In the method, the synthesizing (step (4)) of the RNA single strand comprising the sequence complementary to that of the RNA single strand prepared in step (3) may be performed as a independent synthetic process before step (1) or in any one step of step (1) to step (6).

That is, nanoparticles comprising a form in which the hydrophobic compound is positioned at the center of the nanoparticles and the hydrophilic compound is positioned in a direction toward the outside of the ZBTB7A, YAP1 and/or CHD1L specific siRNA to protect the ZBTB7A, YAP1 and/or CHD1L specific siRNA may be formed.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0125]    Hereinafter, the present invention will be described in detail through Examples. However, these Examples are only to illustrate the present invention, and those skilled in the art will appreciate that these Examples are not to be construed as limiting a scope of the present invention. 
       Example 1 
     Design of Target Sequences of ZBTB7A, YAP1 and CHD1L Gene, and Preparation of siRNA 
       [0126]    100 kinds of target sequences (sense strand) capable of binding to an mRNA sequence (NM_015898) of ZBTB7A gene, an mRNA sequence (NM_006106) of YAP1 gene, or an mRNA sequence (NM_004284) of CHD1L gene were designed per each gene, and antisense siRNA strands comprising a sequence complementary to the desired base sequence were prepared. First, the desired base sequence to which the siRNA may bind was designed from the mRNA sequences of the corresponding genes using a Turbo si-Designer developed by Bioneer. siRNA for liver cancer related genes of the present invention has a double-stranded structure composed of a sense strand comprising 19 nucleotides and an antisense strand complementary thereto. In addition, siCONT (SEQ ID NO. 301), which is a siRNA comprising a sequence that does not inhibit expression of genes, was prepared. The siRNA is prepared by connecting a phosphodiester bond configuring a RNA backbone structure using β-cyanoethyl phosphoramidite (Nucleic Acids Research, 12: 4539-4557, 1984). More specifically, a reactant containing RNA comprising a desired length was obtained by repeating a series of processes consisting of deblocking, coupling, oxidation, and capping on a solid support on which nucleotides were adhered using an RNA synthesizer (384 Synthesizer, Bioneer, Korea). The RNA was separated from the reactant and purified using a HPLC (LC918, Japan Analytical Industry, Japan) equipped with a Daisogel C18 (Daiso, Japan) column. Then, whether or not the purified RNA coincides with the desired base sequence was confirmed using a MALDI-TOF mass spectrometer (Shimadzu, Japan). Next, the desired double-stranded siRNAs comprising sense strand of SEQ ID NOs. 1 to 301, 310 to 312 were prepared by binding the sense and antisense RNA stands to each other (See Table 1).

       Example 2 
     Preparation of Double-Stranded Oligo RNA Molecules (SAMiRNA LP) 
       [0127]    The double-stranded oligo RNA molecules (SAMiRNA LP) prepared in the present invention had a structure of the following Structural Formula (5). 
         [0000]      C 24 -5′-S-3′-PEG
 
         [0000]      AS  Structural Formula (5)
 
         [0128]    In Structural Formula (5), S is a sense strand of siRNA; AS is an antisense strand of the siRNA; PEG is a polyethylene glycol as a hydrophilic compound; C 24  is tetradocosane including a disulfide bond as a hydrophobic compound; and 5′ and 3′ mean orientations of ends of the double-stranded oligo RNA. 
         [0129]    In the case of the sense strand of the siRNA in Structural Formula (5), oligo RNA-hydrophilic compound molecule comprising a sense strand of which polyethylene glycol was bound to a 3′-end region was synthesized by a method of connecting the phosphodiester bond configuring the backbone structure of the RNA using β-cyanoethyl phosphoramidite as described above while using polyethylene glycol (PEG, Mn=2,000)-CPG prepared according to a method in Example 1 disclosed in the existing Patent (KR 2012-0119212A) as the support, and then tetradocosane including the disulfide bond was bound to a 5′-end region, thereby preparing a sense strand of the desired RNA-polymer molecules. In the case of the antisense strand to be annealed with the strand, the antisense strand comprising the sequence complementary to that of the sense strand was prepared by the above-mentioned reaction. 
         [0130]    After synthesizing was completed, the synthesized RNA single strand and the RNA polymer molecules were separated from the CPG by treating the reactants with ammonia (28% (v/v)) in a water bath at 60° C., and then a protective residue was removed by a deprotection reaction. The RNA single strand and the RNA polymer molecules from which the protective residue was removed were treated with N-methylpyrrolidone, triethylamine, and triethylaminetrihydrofluoride at a volume ratio of 10:3:4 in an oven at 70° C., thereby removing tert-butyldimethylsilyl (2′TBDMS). 
         [0131]    The RNA was separated from the reactant and purified using a HPLC (LC918, Japan Analytical Industry, Japan) equipped with a Daisogel C18 (Daiso, Japan) column. Then, whether or not the purified RNA coincides with the desired base sequence was confirmed using a MALDI-TOF mass spectrometer (Shimadzu, Japan). Thereafter, in order to prepare each of the double-stranded oligo RNA polymer molecules, the same amount of sense and antisense strands were mixed and put into 1× annealing buffer (30 mM HEPES, 100 mM potassium acetate, 2 mM magnesium acetate, pH 7.0-7.5), followed by reacting with each other in a water bath at 90° C. for 3 minutes and reacting with each other again at 37° C., thereby preparing the double-stranded oligo RNA molecules containing siRNAs of the SEQ ID NOs. 1 to 8, 103, 107, 108, 112, 116 to 118, 121, 122, 201 to 204 and 301 as a sense strand, respectively (hereinafter, referred to as SAMiRNALP-ZBTB, SAMiRNALP-YAP, SAMiRNALP-CHD, SAMiRNALP-CONT, respectively). It was confirmed through electrophoresis that the prepared double-stranded oligo RNA molecules were annealed.

       [0134]    After dissolving SAMiRNALP-ZBTB in 1.5 ml, Dulbecco&#39;s Phosphate Buffered Saline (DPBS) at a concentration of 50 μg/ml, nanoparticle powder was prepared by lyophilization at −75° C. and 5 mTorr for 48 hours and dissolved in the DPBS as a solvent, thereby preparing homogeneous nanoparticles. SAMiRNALP-YAP, SAMiRNALP-CHD and SAMiRNALP-CONT were prepared by using the same method.

     Measurement of Sizes and Polydispersity Indexes (Hereinafter, Referred to as ‘PDI’) of Nanoparticles 
       [0135]    The sizes of the nanoparticles were measured using a zeta-potential measurement. The sizes of the homogeneous nanoparticles prepared in Example 3-1 were measured using the zeta-potential measurement (Nano-ZS, MALVERN, UK). Here, a refractive index and absorption index for compounds were set to 1.459 and 0.001, respectively. In addition, a temperature of DPBS as the solvent was input as 25° C., and viscosity and a refractive index thereof were input as 1.0200 and 1.335, respectively. A one-time measurement consists of 15 repetitive size measurements, and this measurement was repeated six times.

       [0139]    After 1×10 5  Hep3B cell lines and 1×10 5  Huh-7 cell lines cultured in the Example 4-1 were cultured in a 12-well plate using the EMEM at 37° C. under 5% (v/v) CO 2  atmosphere for 18 hours, the medium was removed, and then 500 μl of Opti-MEM medium (GIBCO, US) was dispensed in each well. 
         [0140]    Meanwhile, 1.5 μl of Lipofectamine™ RNAi Max (Invitrogen, US) and 248.5 μl of the Opti-MEM medium were mixed with each other to prepare a mixed solution and then reacted with each other at room temperature for 5 minutes. Then, 0.2, 1 or 5 μl of each of the siRNAs (1 pmole/μl) comprising SEQ ID NOs. 1 to 8 and 310 (ZBTB7A-Ref (J Biomed Biotechnol. 2009; 2009:514287)) for ZBTB7A, SEQ ID Nos. 103, 107, 108, 112, 116 to 118, 121, 122 and 311 (YAP1-Ref (Molecular Cell, Vol. 11, 11-23, January, 2003)) for YAP1, and SEQ ID Nos. 201 to 204 and 312 (CHD1L-Ref (J Clin Invest 2010 Apr. 1; 120(4): 1178-91)) for CHD1L as a sense strand prepared in Example 1 was added to 230 μl of the Opti-MEM medium, thereby preparing a siRNA solution comprising a final concentration of 0.2, 1, 5 or 20 nM. The Lipofectamine™ RNAi Max mixed solution and the siRNA solution were mixed and then reacted with each other at room temperature for 20 minutes, thereby preparing a solution for transfection. 
         [0141]    Thereafter, 500 μl of the solution for transfection was dispensed in each well containing tumor cell lines and the dispensed Opti-MEM medium and cultured for 6 hours, followed by removal of the Opti-MEM medium. Here, 1 ml of the EMEM medium was dispensed in each well and cultured at 37° C. under 5% (v/v) CO 2  atmosphere for 24 hours.

     Quantitative Analysis of Target Gene mRNA 
       [0142]    Total RNA was extracted from the cell lines transfected in the example 4-2 to prepare cDNA, and then a target gene mRNA expression level was relatively quantified using a real-time polymerase chain reaction (PCR). 
       Example 4-3-1 
     Separation of RNA from Transfected Cells and Preparation of cDNA 
       [0143]    Total RNA was extracted from the cell lines transfected in the example 4-2 by using an RNA extraction kit (AccuPrep Cell total RNA extraction kit, Bioneer, Korea), and cDNA was prepared from the extracted RNA using an RNA reverse transcriptase (AccuPower CycleScript RT Premix/dT20, Bioneer, Korea), as follows. More specifically, 1 μg of the extracted RNA was put into each of the 0.25 ml Eppendorf tubes containing AccuPower CycleScript RT Premix/dT20 (Bioneer, Korea), and distilled water treated with diethyl pyrocarbonate (DEPC) was added so as to have a total volume of 20 μl. Two steps of RNA-primer hybridization at 30° C. for 1 minute and preparation of cDNA at 52° C. for 4 minutes were repeated six times using a PCR machine (MyGenie™ 96 Gradient Thermal Block, Bioneer, Korea), and then the amplification reaction was terminated by inactivating enzymes at 95° C. for 5 minutes. 
       Example 4-3-2 
     Relative Quantitative Analysis of Target Gene mRNA 
       [0144]    The relative level of liver cancer related gene mRNA was quantified through the real-time PCR using the cDNA prepared in the example 4-3-1 as a template as follows. The cDNA prepared in the example 4-3-1 was diluted 5 times with distilled water in each well of a 96-well plate, and then in order to accurately analyze the target gene mRNA expression level, 3 μl of the diluted cDNA, 10 μl of 2× GreenStar™ PCR master mix (Bioneer, Korea), 6 μl of distilled water, and 1 μl of ZBTB7A qPCR primers (each of F and R: 10 pmole/μl, Bioneer, Korea, See Table 2) were used to prepare a mixed solution. Meanwhile, in order to normalize the target gene mRNA expression level, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), which is a housekeeping gene (hereinafter, referred to as HK gene), was used as a reference gene. The following reaction was performed on the 96-well plate containing the mixed solution using an Exicycler™96 Real-Time Quantitative Thermal Block (Bioneer, Korea). Enzyme activation and a secondary structure of cDNA were removed by performing the reaction at 95° C. for 15 minutes. Then, four steps of denaturing at 94° C. for 30 seconds, annealing at 58° C. for 30 seconds, extension at 72° C. for 30 seconds, and SYBR green scan were repetitively performed 42 times, and then a final extension was performed at 72° C. for 3 minutes. Thereafter, the temperature was maintained at 55° C. for 1 minute, and a melting curve of 55° C.-95° C. was analyzed. After finishing the PCR, each of the obtained threshold cycle (Ct) values of the target genes was corrected using the GAPDH gene, thereby obtaining the corrected Ct value of the target gene. Then, a difference (ΔCt) in Ct value was calculated using an experimental group treated with the siRNA(siCONT) comprising a control sequence that does not inhibit gene expression as a control group. The expression levels of the target genes in the cells treated with ZBTB7A specific siRNAs comprising sense strand of SEQ ID NOs. 1 to 8 and ZBTB7A-Ref were relatively quantified, respectively, using the ΔCt values and the calculation equation of 2(−ΔCt)×100 (See  FIG. 2 ). 
         [0145]    In addition, in each of the experimental groups treated with YAP1 or CHD1L specific siRNAs (SEQ ID NOs. 103, 107, 108, 112, 116 to 118, 121, 122, YAP1-Ref, 201 to 204 and CHD1L-Ref), mRNA of the target gene was relatively quantified by the same method using the YAP1 or CHD1L qPCR primer and the GAPDH qPCR primer ( FIGS. 3 and 4 ). 
         [0146]    In order to select the siRNA comprising high efficiency, the siRNAs used in the case in which the mRNA expression levels for each gene at the concentrations of 0.2 nM and 1 nM were commonly significantly decreased were selected (SEQ ID NOs. 4, 118, and 204 as a sense strand).

Meanwhile, 1.5 μl of Lipofectamine™ RNAi Max (Invitrogen, US) and 248.5 μl of the Opti-MEM medium were mixed with each other to prepare a mixed solution and then reacted with each other at room temperature for 5 minutes. Then, 0.8 or 0.4 μl of each of the siRNAs (0.01 pmole/μl) comprising sense strand of the SEQ ID NOs. 1, 102, and 201 prepared in Example 1 or 0.2, 1, or 5 μl of each of the siRNAs (1 pmole/μl) comprising sense strand of the SEQ ID NOs. 1, 102, and 201 was added to 230 μl of the Opti-MEM medium, thereby preparing a siRNA solution comprising a final concentration of 8 pM, 40 pM, 0.2 nM, 1 nM, or 5 nM.

Here, 1 ml of the RPMI 1640 culture medium was dispensed in each well and cultured at 37° C. under 5% (v/v) CO 2  atmosphere for 24 hours. 
         [0167]    Cell viability was confirmed by comparing the number of cells with that in the Experimental group treated with the siRNA comprising sense strand of SEQ ID NO. 301 ( FIG. 12 ). 
         [0168]    It may be confirmed that in the case in which the cell lines treated with the siRNAs of the SEQ ID NO. 4, 118 or 204, cell viability was concentration-dependently decreased, and the growth suppression effect was excellent ( FIG. 8 ).

     Colony Forming Assay for Confirming Inhibition Effect of ZBTB7A, YAP1 or CHD1L Specific siRNA 
       [0169]    A method of measuring transformation of cells by performing a colony forming assay on a single cell in vitro is a semi-quantitative method and is derived from lost of contact inhibition by the cancer cell and anchorage independent phenotypic characterizations of the cancer cell. This assay method is used to confirm survival of cancer cells by a specific anticancer drug in vitro in the case in which the cancer cells were treated with the corresponding anticancer drug (Clonogenic Assay of Cells in Vitro, Nat. Protoc. 1(5): 2315-9, 2006). 
         [0170]    In order to confirm how much colony forming of the cancer cells was inhibited by the high efficiency ZBTB7A, YAP1 or CHD1L specific siRNA selected in Example 4-3-2, the colony forming assay (CFA) was performed. The hep3B and Huh-7 cell lines cultured in Example 5-1 were inoculated in a 35 mm Petri-dish (1×10 4 /dish), respectively. After 20 hours, the cells were transfected at a concentration of 5 nM or 20 nM by the same method as that in Example 5-2. The culture medium of the transfected cells was replaced once every three days, and after 10 to 14 days of the transfection, the cells were stained with Diff Quik (Sysmex, Japan) to compare colony forming degrees with each other ( FIG. 9 ). It may be confirmed that in groups treated with the siRNAs comprising SEQ ID NO. 1 and 118 as a sense strand, colonies were concentration-dependently formed at a significantly low level as compared to the control group treated with the siRNA comprising sense strand of SEQ ID NO. 301 ( FIG. 9 ).
