Abstract
Description
[0001] This application is a divisional application of the patent application with the application date of March 22, 2021, application number 202180024163.1, and invention name "Structure of oncolytic virus comprising bispecific nucleic acid molecules". Technical Field
[0002] The present invention relates to an anti-tumor adenovirus and an anti-cancer composition containing the same. Background Art
[0003] Cancer is one of the leading causes of death worldwide. The development of innovative cancer therapeutics can reduce medical costs and create high added value. Furthermore, according to 2008 statistics, molecular therapeutics that can overcome resistance to existing anticancer agents represented a market size of US$17.5 billion in seven major countries (the US, Japan, France, Germany, Italy, Spain, and the UK). By 2018, the market size had reached approximately US$45 billion, with a projected growth rate of 9.5% compared to 2008. Cancer treatment is divided into surgery, radiotherapy, chemotherapy, and biological therapy. Among them, chemotherapy is a treatment method that inhibits the proliferation of cancer cells or kills cancer cells by using chemical substances. Since most of the toxicity exhibited by anticancer drugs is also expressed in normal cells, it has a certain degree of toxicity. Since anticancer drugs will lose their original effects after a certain period of use, drug resistance will occur. Therefore, it is urgent to develop anticancer drugs that selectively act on cancer cells and do not produce drug resistance (Current Status of Cancer Control Biowave 2004.6(19)). Recently, by securing molecular genetic information about cancer, new anticancer drugs that target the molecular characteristics of cancer have been developed. There are reports that anticancer drugs that target specific molecular targets that only cancer cells have will not produce drug resistance.
[0004] Technology that inhibits gene expression is an important tool in the development of therapeutic agents and target testing for treating diseases. RNA interference (hereinafter referred to as RNAi) was discovered and confirmed to act on sequence-specific messenger RNA (mRNA) in a variety of mammalian cells (Silence of the transcripts: RNA interference in medicine. J Mol Med (2005) 83:764-773). RNAi is a phenomenon in which small interfering RNA (hereinafter referred to as siRNA), which is a 21-25 nucleotide double-helical structure, specifically binds to transcripts (mRNA transcripts) with complementary sequences, degrading the transcripts and thereby inhibiting the expression of specific proteins. Inside the cell, double-stranded ribonucleic acid (RNA) is converted into 21-23 basepair (bp) double-stranded small interfering RNA (siRNA) by endonuclease called nuclease (Dicer). siRNA will bind to the RNA-induced silencing complex (RISC), allowing the guide (antisense) chain to recognize the target messenger RNA and decompose it, thereby sequence-specifically inhibiting the expression of the target gene (NUCLEIC-ACID THERAPEUTICS: BASIC PRINCIPLES AND RECENT APPLICATIONS. Nature Reviews Drug Discovery. 2002.1, 503-514). According to a report by Bertrand's research team, compared with antisense oligonucleotides (ASOs), small interfering RNA (siRNA) has a superior inhibitory effect on messenger RNA (mRNA) expression in vitro and in vivo for the same target gene, and this effect can be sustained (Comparison of antisense oligonucleotides and siRNAs in cell culture and in vivo. Biochem. Biophys. Res. Commun. 2002. 296: 1000-1004).According to analysis, the market for therapeutic agents based on RNA interference (RNAi) technology, including small interfering RNA (siRNA), will reach a total market size of more than 12 trillion won worldwide by 2020. The scope of application of this technology will be unprecedentedly expanded, and it is considered a next-generation gene therapy technology that can treat diseases that are difficult to treat with existing antibody-based and compound-based drugs. In addition, the mechanism of action of small interfering RNA (siRNA) is to regulate the expression of target genes in a sequence-specific manner by complementary binding to target messenger RNA (mRNA). Therefore, the development time and cost of existing antibody-based drugs or chemical substances (small molecule drugs) to optimize specific protein targets are very long. However, compared with this, the scope of application will be unprecedentedly expanded, the development time will be shortened, and it has the advantage of being able to develop guide compounds that can optimize all protein targets, including target substances that cannot be drugged (Progress Towards in Vivo Use of siRNAs. MOLECULAR THERAPY. 2006 13(4):664-670). To this end, recent research is underway to address the challenges posed by RNA-mediated interference in the development of existing chemically synthesized pharmaceuticals, while also aiming to develop therapeutics for various diseases, particularly tumors, by selectively inhibiting the expression of specific proteins at the transcriptome level. Furthermore, unlike existing anticancer agents, small interfering RNA (siRNA) therapeutics offer the advantage of predictable side effects due to their well-defined targets. However, this target specificity can also lead to limited therapeutic efficacy in tumors, which are diseases caused by multiple genetic factors. Summary of the Invention
[0005] Technical issues
[0006] The purpose of the present invention is to provide an anti-tumor adenovirus.
[0007] Furthermore, the present invention aims to provide a cancer treatment composition.
[0008] Technical Solution
[0009] To achieve the above-mentioned object, the present invention provides an anti-tumor adenovirus comprising a base sequence targeting a first nucleic acid and a base sequence targeting a second nucleic acid.
[0010] Furthermore, the present invention provides a cancer treatment composition comprising the above-mentioned anti-tumor adenovirus.
[0011] Effects of the Invention
[0012] According to the present invention, the double-stranded small interfering RNA (siRNA) of the present invention promotes the killing of cancer cells by simultaneously inhibiting the expression of the first nucleic acid and the second nucleic acid. The anti-cancer activity is significantly better than that of treating individual small interfering RNAs (siRNA) together, and has the effect of synergistically improving the cancer cell killing efficacy during combined treatment with anticancer agents. The adenovirus containing an expression cassette encoding a short hairpin RNA (shRNA) for expressing an anti-tumor adenovirus and a human telomerase reverse transcriptase (hTERT) promoter has the effect of avoiding the body's immune response to specifically deliver to cancer cells and achieve systemic therapeutic efficacy. It can achieve local delivery, has excellent selectivity, and can exhibit significant anti-cancer effects through minimally invasive treatment. It can be effectively used as an anti-cancer composition or anti-cancer adjuvant for various cancers. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present invention will be described in detail below using examples of the present invention. However, the following examples are merely illustrative of the present invention and are not intended to be limiting. Various modifications and applications of the present invention are possible within the scope of the appended claims and their equivalents.
[0055] Unless otherwise indicated, nucleic acids are recorded from left to right in a 5'→3' orientation.Numerical ranges listed in the specification are inclusive of the numbers defining the range, including each integer and any non-integer division within the defined range.
[0056] Unless otherwise explained, all technical and scientific terms used in this application have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Any methods and materials similar or equivalent to those described in this application can be used in the procedures used to test the present invention, but preferred materials and methods are described herein.
[0057] In one embodiment, the present invention relates to an anti-tumor adenovirus comprising: a human telomerase reverse transcriptase (hTERT) promoter; and an expression cassette comprising a base sequence targeting a first nucleic acid and a base sequence targeting a second nucleic acid.
[0058] In one example, the base sequence of the first nucleic acid as the target sequence and the base sequence of the second nucleic acid as the target sequence can be partially reverse complementary sequences or 100% reverse complementary sequences. When expressed in an organism, the sequence of the first nucleic acid as the target sequence and the sequence of the second nucleic acid as the target sequence form a double strand, preferably, a short hairpin ribonucleic acid (shRNA).
[0059] In one example, the base sequence of the first nucleic acid as the target sequence and the base sequence of the second nucleic acid as the target sequence can be combined in a partially complementary or 100% complementary manner to form a double strand during gene expression.
[0060] In one example, the human telomerase reverse transcriptase (hTERT) promoter can be operably linked to an endogenous gene of an adenovirus.
[0061] In the present invention, the term "operably linked" refers to the functional combination between a gene expression regulatory sequence (e.g., a promoter, a signal sequence, or an array of transcriptional regulatory factor binding sites) and other gene sequences, so that the above-mentioned regulatory sequence will regulate the transcription and / or interpretation of the above-mentioned other gene sequences.
[0062] In one example, the human telomerase reverse transcriptase (hTERT) promoter may include the base sequence of SEQ ID NO: 74. Furthermore, the human telomerase reverse transcriptase (hTERT) promoter sequence may include various known variant sequences.
[0063] In one example, the endogenous gene of the adenovirus may have a 3'ITR structure of 5'ITR-C1-C2-C3-C4-C5, wherein C1 may include E1A (SEQ ID NO: 75), E1B (SEQ ID NO: 77), or E1A-E1B, C2 may include E2B-L1-L2-L3-E2A-L4, C3 may include or exclude E3, C4 may include L5, and C5 may include or exclude E4, and may include the base sequence of SEQ ID NO: 78.
[0064] In one example, the E3 region of the adenovirus may be partially deleted, and the deleted base sequence may include the base sequence of SEQ ID NO: 82.
[0065] In one example, the expression cassette can be located at the C3 site of an endogenous gene of the adenovirus.
[0066] In one example, the human telomerase reverse transcriptase (hTERT) promoter can be operably linked to the endogenous genes E1A and E1B of an adenovirus.
[0067] In one example, an internal ribosome entry site (IRES) sequence (SEQ ID NO: 76) may be further included between E1A and E1B of the endogenous gene of the adenovirus.
[0068] In one example, the expression cassette can encode and express short hairpin RNA (shRNA).
[0069] In one example, the short hairpin RNA (shRNA) can simultaneously inhibit the expression of the first nucleic acid and the second nucleic acid.
[0070] In one example, the anti-tumor adenovirus of the present invention can degrade messenger RNA (mRNA) of nucleic acid or inhibit translation through RNA interference, thereby inhibiting expression.
[0071] In one example, the expression cassette of the present invention can simultaneously inhibit the first nucleic acid and the second nucleic acid by expressing a double-stranded small interfering ribonucleic acid (siRNA) whose specific sense strand binds complementary to the first nucleic acid or the second nucleic acid portion and whose specific antisense strand binds complementary to the second nucleic acid or the first nucleic acid portion.
[0072] The term "expression inhibition" as used in the present invention refers to causing a decrease in the expression or translation of a target gene, preferably, to the point where the expression of the target gene is undetectable or insignificant.
[0073] The term "small interfering RNA (siRNA)" as used in the present invention refers to a short double-stranded RNA that causes RNA interference (RNAi) by cleaving a specific messenger RNA (mRNA). Generally, a small interfering RNA (siRNA) is composed of a sense RNA (RNA) chain having the same sequence as the messenger RNA (mRNA) of the target gene and an antisense RNA (RNA) chain having a complementary sequence thereto. However, the double-stranded small interfering RNA (siRNA) of the present invention is a small interfering RNA (siRNA) in which the sense RNA (RNA) chain is specific to the first nucleic acid or the second nucleic acid (the antisense chain to the first nucleic acid or the second nucleic acid), and the antisense RNA (RNA) chain is a small interfering RNA (siRNA) specific to the second nucleic acid or the first nucleic acid (the antisense chain to the second nucleic acid or the first nucleic acid). Therefore, the double-stranded small interfering RNA (siRNA) can simultaneously inhibit the first nucleic acid or the second nucleic acid or inhibit their expression.
[0074] The term "short hairpin RNA (shRNA)" in the present invention refers to the following ribonucleic acid, that is, by partially including a striated base sequence in a single-stranded ribonucleic acid (RNA) to form a double-stranded structure in the 3' region and a hairpin-like structure, which can be converted into a small interfering ribonucleic acid (siRNA) after being expressed in cells by cleavage by dicer, a type of ribonuclease (RNase) present in the cells. The length of the above-mentioned double-stranded structure is not particularly limited, but is preferably 10 nucleotides or more, and more preferably 20 nucleotides or more. In the present invention, the above-mentioned short hairpin RNA (shRNA) can be contained in an expression cassette, and the above-mentioned short hairpin RNA (shRNA) can be produced as follows, that is, in a group sequence consisting of an antisense chain and a sense chain of a small interfering RNA (siRNA) for each gene, after converting U to T, TTGGATCCAA (TTGGATCCAA loop) or TTCAAGAGAG (TTCAAGAGAG loop), an antisense chain and TT are connected to the 3' of the sense chain to prepare an expression cassette encoding the short hairpin RNA (shRNA) so that it is expressed in cells.
[0075] In one example, the first nucleic acid may include a base sequence having 60% or greater complementarity with the reverse complementary sequence of the second nucleic acid, and the second nucleic acid may include a base sequence having 60% or greater complementarity with the reverse complementary sequence of the first nucleic acid.
[0076] In one example, the first nucleic acid may comprise a base sequence that is 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or more complementary to the reverse complement sequence of the second nucleic acid, and the second nucleic acid may comprise a base sequence that is 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or more complementary to the reverse complement sequence of the first nucleic acid.
[0077] Variants of the base sequence of the first nucleic acid contained in the expression cassette as the target sequence or the base sequence of the second nucleic acid as the target sequence are included within the scope of the present invention. The concept of the expression cassette of the present invention is as follows, namely, it includes functional equivalents of the nucleic acid molecules that constitute it, for example, including variants that can functionally perform the same function as the base sequence molecules although the base sequence of the nucleic acid molecules is partially modified by deletion, substitution, or insertion. The "% sequence homology" for nucleic acid molecules can be confirmed by comparing two optimally aligned sequences and a comparison region. A portion of the nucleic acid molecule sequence in the comparison region may include additions or deletions compared to the reference sequence (excluding additions or deletions) for the optimal alignment of the two sequences.
[0078] In one example, the nucleic acid can be a gene associated with cancer.
[0079] In one example, the gene associated with cancer can be an oncogene whose expression increases in cancer, and the oncogene can be an apoptosis-related gene, a transcription factor gene, a metastasis-related gene, an angiogenesis-related gene, a cancer cell-specific gene, or a tyrosine kinase gene.
[0080] In one embodiment, the apoptosis-related genes may be ABL1, AKT1, AKT2, BARD1, BAX, BCL11B, BCL2, BCL2A1, BCL2L1, BCL2L12, BCL3, BCL6, BIRC2, BIRC3, BIRC5, BRAF, CARD11, CAV1, CBL, CDC25A, CDKN1A, CFLAR, CNR2, CTNNB1, CUL4A, DAXX, DDIT3, E2F1, E2F3, E2F 5.

[0155] To express the siRNAs prepared in the above examples in cells, multiple short hairpin RNA (shRNA) expression cassettes (TTGGATCCAA circular shRNA and TTCAAGAGAG circular shRNA) containing double-stranded sequences of dual-target siRNAs and loop sequences were prepared. Specifically, TTGGATCCAA (TTGGATCCAA loop) or TTCAAGAGAG (TTCAAGAGAG loop), the antisense strand, and TT were linked to the 3' end of the sense strand of the siRNA set (SEQ ID NOs. 63 and 64) listed in Table 7, from 5' to 3'. DNA sequences encoding the shRNAs were prepared and are shown in Table 11 (small interfering RNAs (siRNAs) are represented by capital letters, and additional sequences are represented by lowercase letters). The prepared multiple short hairpin RNA (shRNA) expression cassettes were respectively configured into pE3.1 vector ( Figure 1) was located after the U6 promoter (sequence number 65) in the cleavage site of the restriction enzymes PstⅠ and EcoRⅤ, thereby preparing a recombinant expression vector that expresses two short hairpin RNAs (shRNAs) containing dual-target small interfering RNAs (siRNAs) targeting c-MET and PD-L1 in cells.

[0159] 3-1. Inhibition of mTOR and STAT3 expression
[0160] After injecting Hela cells into 12-well plates, they were cultured in serum-free cell freezing medium (RPMI, Hyclone) supplemented with 10% fetal bovine serum (FBS, Hyclone) at 37°C and 5% CO2 until the cell density reached 50%. Afterwards, the cells were transfected with the double-target small interfering RNA (siRNA) of groups 1 to 9 prepared in Example 1 above using a transfection reagent (lipofectamine3000, Invitrogen, Carlsbad, CA, USA) to knock down mTOR and STAT3 simultaneously. After 48 hours of transfection, total ribonucleic acid (RNA) was extracted using GeneJET RNAPurification Kit (Invitrogen) by disrupting the cells. The extracted total ribonucleic acid (RNA) was used as a template to perform a reverse transcription reaction using RevoScriptTM RT PreMix (iNtRON BIOTECHNOLOGY). Reactions for mTOR (Hs00234522_m1), STAT3 (Hs01047580_m1), and GAPDH (Hs02758991_g1) were performed using 20 μl of sample containing 25 to 200 ng of reverse-transcribed complementary deoxyribonucleic acid (cDNA), AmpONE Taq DNA polymerase (GeneAll), and TaqMan Gene Expression assays (Applied Biosystems) using the ABIPRISM 7700 Sequence Detection System and QS3 Real-time PCR (Biosystems). Real-time polymerase chain reaction (PCR) conditions consisted of a 50°C (2 minutes) followed by a 95°C (10 minutes) cycle, and a 95°C (15 seconds) followed by a 60°C (60 seconds) cycle, for a total of 40 cycles. All reactions were repeated three times, and the average value was calculated. The multiple results thus obtained were used for normalization of the messenger RNA (mRNA) values of GAPDH, which is a housekeeping gene.
[0161] The results showed that the dual-target siRNA in Groups 1 to 9 confirmed that the remaining expression of mTOR and STAT3 was about 20% to 40% compared with the control group, indicating that the dual-target siRNA can simultaneously inhibit the expression of two genes ( Figure 2 ).
[0162] 3-2. Inhibition of BCL2 and BI-1 expression
[0163] After HeLa cells were injected into 12-well plates, they were cultured in serum-free cell freezing medium (RPMI, Hyclone) supplemented with 10% fetal bovine serum (FBS, Hyclone) at 37°C and 5% CO2 until the cell density reached 50%. Subsequently, 80 pmoles of the double-target small interfering RNA (siRNA) group 10 and (si-BB1) and double-target small interfering RNA (siRNA) groups 11 to 15 prepared in Example 1 (Table 2) were transfected into the wells cultured with HeLa cells using 3 μl of transfection reagent (lipofectamine 3000, Invitrogen, Carlsbad, CA, USA) to simultaneously knock down BCL2 and BI-1. 48 hours after transfection, total RNA was extracted using the GeneJET RNA Purification Kit (Invitrogen) by disrupting the cells. After the extracted total RNA was used as a template for reverse transcription into complementary deoxyribonucleic acid (cDNA) by real-time polymerase chain reaction (RT-PCR), the messenger RNA (mRNA) expression levels of BCL2 and BI-1 based on dual-target small interfering RNA (siRNA) were confirmed by quantitative polymerase chain reaction (q-PCR). As a reference, the probes used were Bcl2 (Thermo, Hs00608023_m1), BI-1 (Thermo, Dm01835892_g1), and GAPDH (Thermo, Hs02786624_g1), and the QS3 equipment was used to perform them. All reactions were repeated 3 times and the average value was taken. The multiple results thus obtained were used to normalize the messenger RNA (mRNA) values of GAPDH, a housekeeping gene.
[0164] The results showed that the dual-target siRNA group reduced the expression of BCL2 and BI-1, indicating that the dual-target siRNA of the present invention can simultaneously inhibit the expression of two genes ( Figure 3 and Figure 4 ).
[0165] Therefore, the dual-target small interfering RNA (siRNA) of the present invention can simultaneously inhibit the expression of two genes, and thus has been confirmed to exhibit significant anticancer activity by promoting the killing of cancer cells, showing that it can be effectively used as an anticancer composition or anticancer adjuvant for various tumors.
[0166] 3-3. Inhibition of AR and mTOR expression
[0167] After PC3, h460, and A549 cells were injected into 12-well plates, they were cultured in serum-free cell freezing medium (RPMI, Hyclone) supplemented with 10% fetal bovine serum (FBS, Hyclone) at 37°C and 5% CO2 until the cell density reached 50%. Then, 80 pmole of the dual-target small interfering RNA (siRNA) groups 16 to 28 (Table 3) prepared in Example 1 were transfected into the wells containing the cells using 3 μl of lipofectamine 3000 (Invitrogen, Carlsbad, CA, USA) to simultaneously knock down AR and mTOR. Among them, group 16 was transfected into h460 cells, and group 17 was transfected into PC3 cells, thereby performing knockdown. As its positive control group, the small interfering ribonucleic acid (siRNA) for AR and the small interfering ribonucleic acid (siRNA) for mTOR described in Table 12 were transfected respectively. After 48 hours of transfection, total ribonucleic acid (RNA) was extracted using GeneJET RNA Purification Kit (Invitrogen) by fragmenting the cells. After the extracted total ribonucleic acid (RNA) was reverse transcribed into complementary deoxyribonucleic acid (cDNA) by real-time polymerase chain reaction (RT-PCR) as a template, the expression of messenger ribonucleic acid (mRNA) of AR and mTOR based on small interfering ribonucleic acid (siRNA) and the dual-target small interfering ribonucleic acid (siRNA) groups 16 to 28 (si-AT1 to siAT13) of the present invention was confirmed by quantitative polymerase chain reaction (q-PCR). To confirm the expression level of messenger RNA (mRNA), a primer set for AR or mTOR and a reaction mixture [2 μl of 10X reaction buffer, 2 μl of HQ buffer, 1.6 μl of dNTPs, 1 μl each of Primer (F, R, 10 pmoles / ul), 2 μl of Template (500 ng), 0.2 μl of Taq, 10.2 μl of DW, total volume 20 μl] were used. AR and mTOR mRNA in knocked-down cell fragments were converted into complementary deoxyribonucleic acid (cDNA) under polymerase chain reaction (PCR) conditions [95°C for 2 minutes, 30 cycles of 95°C for 20 seconds, 60°C for 10 seconds, 72°C for 30 to 60 seconds, and 72°C for 5 minutes].Reverse-transcribed complementary deoxyribonucleic acid (cDNA) was used as a template to prepare a reaction mixture [Template (RT-PCR product) 6 μl, Taqman probe 3 μl, 10X reaction buffer 6 μl, HQ buffer 6 μl, dNTP 4.8 μl, Taq 0.6 μl, DW 10.2 μl, total volume 60 μl]. Quantitative polymerase chain reaction (q-PCR) was performed [95°C for 10 minutes, 95°C for 15 seconds, and 60°C for 40 cycles per minute]. For reference, the probes used were AR (Thermo, Hs00171172_m1), mTOR (Thermo, Hs00234508_m1), and GAPDH (Thermo, Hs02786624_g1), using a QS3 instrument. All reactions were repeated three times, and the average value was calculated. The multiple results thus obtained were used for normalization of the messenger RNA (mRNA) values of GAPDH, which is a housekeeping gene.
[0168] Table 12
[0169]
[0170] The results showed that in PC3 cells and h460 cell lines, the expression of AR and mTOr was reduced based on the dual-target small interfering RNA (siRNA) group 16 and group 17 of the present invention ( Figure 5 ), the degree of reduction is similar to or better than the effect of each small interfering RNA (siRNA). In addition, the dual-target small interfering RNA (siRNA) group 17 and group 28 of the present invention reduce the expression of AR and mTOr ( Figure 6 ). Thus, it can be seen that the dual-target small interfering RNA (siRNA) of the present invention can effectively inhibit the expression of two genes at the same time.
[0171] 3-4. Inhibition of c-MET and PD-L1 expression
[0172] Glioblastoma cell line U-87, prostate cancer cell line CWR22Rv-1 (22Rv-1), melanoma cell line A431, and non-small cell lung cancer cell line HCC827 were injected into 12-well plates and cultured in serum-free cell freezing medium (RPMI, Hyclone) supplemented with 10% fetal bovine serum (FBS, Hyclone) at 37°C and 5% CO2 until the cell density reached 50%. Subsequently, 80 pmole of the dual-target small interfering RNA (siRNA) panel prepared in the above example (Table 7) was transfected into the wells containing the cells using 3 μl of lipofectamine 3000 (Invitrogen, Carlsbad, CA, USA) to simultaneously knock down c-MET and PD-L1. 48 hours after transfection, total RNA was extracted using the GeneJET RNA Purification Kit (Invitrogen) by disrupting the cells. The extracted total RNA was used as a template for reverse transcription into complementary deoxyribonucleic acid (cDNA) by real-time polymerase chain reaction (RT-PCR). The messenger RNA (mRNA) expression levels of c-MET and PD-L1 based on small interfering RNA (siRNA) and the dual-target small interfering RNA (siRNA) panel of the present invention were confirmed by quantitative polymerase chain reaction (q-PCR). To confirm the expression level of messenger RNA (mRNA), a primer set for PD-L1 or c-MET and a reaction mixture [2 μl of 10× reaction buffer, 2 μl of HQ buffer, 1.6 μl of dNTPs, 1 μl each of Primer (F, R, 10 pmoles / ul), 2 μl of template (500 ng), 0.2 μl of Taq, 10.2 μl of DW, total volume 20 μl] were used. The c-MET and PD-L1 mRNA in knocked-down cell fragments was converted to complementary deoxyribonucleic acid (cDNA) under polymerase chain reaction (PCR) conditions [95°C for 2 minutes, 30 cycles of 95°C for 20 seconds, 60°C for 10 seconds, 72°C for 30 to 60 seconds, and 72°C for 5 minutes].Furthermore, using the reverse-transcribed complementary deoxyribonucleic acid (cDNA) as a template, a reaction mixture was prepared [Template (RT-PCR product) 6μl, Taqman probe 3μl, 10× reaction buffer 6μl, HQ buffer 6μl, dNTP 4.8μl, Taq 0.6μl, DW 10.2μl, total volume 60μl]. Quantitative polymerase chain reaction (q-PCR) was performed using a QS3 instrument [95°C for 10 minutes, 95°C for 15 seconds, and 60°C for 40 cycles per minute]. All reactions were repeated three times and the average value was calculated. The multiple results obtained were used to normalize the messenger RNA (mRNA) values of GAPDH, a housekeeping gene.
[0173] The results showed that in U-87 cell line, 22Rv-1 cell line, A431 cell line and HCC827 cell line, the expression of c-MET and PD-L1 was reduced based on the dual-target small interfering RNA (siRNA) group of the present invention ( Figure 7 a to Figure 7 d). Thus, it can be seen that the dual-target small interfering RNA (siRNA) of the present invention can effectively inhibit the expression of two genes at the same time.
[0174] Example 4. Confirmation of the gene expression inhibition effect of dual-target small interfering RNA (siRNA) and short hairpin RNA (shRNA)
[0175] 4-1. Gene expression inhibition effect of dual-target short hairpin RNA (shRNA)
[0176] A549 cells and U-87 glioblastoma cells (U87MG) were transfected with 0, 1, and 2 μg of a vector containing the TTGGATCCAA circular short hairpin RNA (shRNA) sequence (SEQ ID NO: 66) or the TTCAAGAGAG circular short hairpin RNA (shRNA) sequence (SEQ ID NO: 67) (Table 8), encoding the mTOR and STAT3 target short hairpin RNA (shRNA) prepared in Example 2, respectively, using a transfection reagent (lipofectamine 3000). Forty-eight hours after transfection, the extent of reduction in mTOR and STAT3 gene expression was confirmed using the real-time polymerase chain reaction (PCR) analysis method described in the above example.
[0177] The results showed that the expression of mTOR and STAT3 was reduced in both short hairpin RNAs (shRNAs) containing the dual-target small interfering RNA (siRNA) of the present invention, and showed a tendency to decrease by 20% in proportion to the amount of deoxyribonucleic acid (DNA) of the short hairpin RNA (shRNA) ( Figure 8 ).
[0178] 4-2. Gene expression of single-target small interfering RNA (siRNA) and dual-target short hairpin RNA (shRNA) Comparison of inhibitory effects
[0179] The gene expression inhibition effects of two single-target small interfering RNAs (siRNAs) linked in tandem using two promoters were compared with those of the dual-target short hairpin RNA (shRNA) of the present invention. Specifically, after tandemly linking a small interfering RNA (siRNA) targeting mTOR and a small interfering RNA (siRNA) targeting STAT3 in the order mTOR-STAT3 or STAT3-mTOR, the gene expression inhibition effects of the mTOR and STAT3 genes were compared with those of the mTOR / STAT3 dual-target short hairpin RNA (shRNA) of the present invention.
[0180] The results showed that in 293T cell lines, compared with the case of using a promoter to connect two small interfering RNAs (siRNAs) to genes in series (direct shmTOR-STAT3 or direct shSTAT3-mTOR), the case of using the dual-target short hairpin RNA (shRNA) of the present invention showed a more significant gene expression inhibition effect ( Figure 9 ).
[0181] Example 5. Confirmation of the cancer cell killing effect based on dual-target small interfering RNA (siRNA)
[0182] In order to confirm the cancer cell killing effect of the dual-target small interfering RNA (siRNA) of Groups 1 to 9 of the present invention, the cells were randomly divided into two groups according to the concentration of 5×10 3 After injecting human lung cancer cell line A549 cells into 96-well plates, the cells were transfected with dual-target small interfering RNA (siRNA) from Group 1 to Group 9 using lipofectamine3000. 48 hours after transfection, the cells were additionally treated with 5 mg / mL MTT (Promega, Ltd.) 24 hours later and cultured for 4 hours. Afterwards, the culture medium was removed and 150 μl of solubilization solution and stop solution were treated, and the cells were cultured at 37°C for 4 hours. The absorbance of the reaction solution was measured at 570 nm, and the cell viability was calculated using the following mathematical formula.
[0183] Mathematical formula 1
[0184] Cell survival rate = absorbance of experimental group (570 nm) / absorbance of control group (570 nm) × 100 (%)
[0185] The results showed that when the dual-target small interfering RNA (siRNA) in Groups 1 to 9 of the present invention was used to simultaneously inhibit mTOR and STAT3, the cell survival rate was significantly reduced compared to the control group. Therefore, it was confirmed that the dual-target small interfering RNA (siRNA) in Groups 1 to 9 of the present invention effectively killed cancer cells ( Figure 10 ).

[0187] 6-1. Combination of mTOR and STAT3 dual-targeting small interfering RNA (siRNA) and anticancer drugs
[0188] 6-1-1. Combination treatment with cisplatin
[0189] In press 5×10 3 After injecting human lung cancer cell line A549 cells into a 96-well plate at 4 μg / well, the cells were transfected with dual-target small interfering RNA (siRNA) (for simultaneous knockdown of mTOR and STAT3) from Groups 1 to 9 of the present invention using lipofectamine 3000. Forty-eight hours after transfection, the cells were treated with 5 μM cisplatin and cultured for 10 hours. Subsequently, an MTT reaction was performed as in the above example, and absorbance was measured at 570 nm to calculate cell viability.
[0190] The results showed that when combined with cisplatin and the dual-target small interfering RNA (siRNA) of Groups 1 to 9 of the present invention was used to simultaneously inhibit mTOR and STAT3, the cell survival rate decreased by about 50% to 70%, and a significant difference was confirmed compared with the control group. Therefore, in the combined treatment with anticancer drugs, when two genes were inhibited simultaneously, it was confirmed that the cell killing effect was significantly improved ( Figure 11 ).
[0191] 6-1-2. Combination treatment with paclitaxel
[0192] In press 5×10 3After injecting human lung cancer cell line A549 cells into a 96-well plate at 4 μg / well, the cells were transfected with dual-target small interfering RNA (siRNA) (for simultaneous knockdown of mTOR and STAT3) from Groups 1 to 9 of the present invention using lipofectamine 3000. Forty-eight hours after transfection, the cells were treated with 5 μM paclitaxel and cultured for 10 hours. Subsequently, an MTT reaction was performed as in Example 4 above, and absorbance was measured at 570 nm to calculate cell viability.
[0193] The results showed that when combined with paclitaxel and the dual-target small interfering RNA (siRNA) of Groups 1 to 9 of the present invention was used to simultaneously inhibit mTOR and STAT3, the cell survival rate decreased by about 30-50%, and a significant difference was confirmed compared with the control group. Therefore, in the combined treatment with anticancer drugs, when two genes were inhibited simultaneously, it was confirmed that the cell killing effect was significantly improved ( Figure 12 ).
[0194] 6-1-3. Combined treatment with 5-fluorouracil (5-FU)
[0195] After injecting human lung cancer cell line A549 cells into 96-well plates at a density of 5×10 cells / well, the cells were transfected with dual-target small interfering RNA (siRNA) (for simultaneous knockdown of mTOR and STAT3) from Groups 1 to 9 of the present invention using lipofectamine 3000. Forty-eight hours after transfection, the cells were treated with 5 μM paclitaxel and cultured for 10 hours. Subsequently, an MTT reaction was performed as described in Example 4 above, and absorbance was measured at 570 nm to calculate cell viability.
[0196] The results showed that when combined with 5-fluorouracil and the dual-target small interfering RNA (siRNA) of Groups 1 to 9 of the present invention was used to simultaneously inhibit mTOR and STAT3, the cell survival rate decreased by about 30%, and a significant difference was confirmed compared to the control group. Therefore, in the combined treatment with anticancer drugs, when two genes were inhibited simultaneously, it was confirmed that the cell killing effect was significantly improved ( Figure 13 ).
[0197] 6-2. Combination treatment with BCL2 and BI-1 dual-targeting small interfering RNA (siRNA) and anticancer drugs
[0198] 6-2-1. Synergistic anticancer effects of BCL2 and BI-1 dual-targeting small interfering RNA (siRNA)
[0199] After transfection of the dual-target small interfering RNA (siRNA) group 1 (si-BB1) of the present invention or individual BCL2 small interfering RNA (siRNA) and BI-1 small interfering RNA (siRNA) as a control group into Hela cells as a human cervical cancer cell line, the anticancer agent was treated for 6 hours according to the type, and then the degree of killing of the cancer cell line was confirmed by MTT analysis. Specifically, 7.5 μl of transfection reagent was used to transfect the Hela cells injected into 6-well plates with 200 pmole per well of small interfering RNA (siRNA) and cultured for 48 hours, and the cell lines were re-injected into 96-well plates and the cell density (2.5×10 4 ) reached 50%. For the control group, the cells were treated with 0.5 μM taxol, 20 μM cisplatin and 10 μM etoposide at different concentrations of anticancer agents, and the cells in the dual-target small interfering RNA (siRNA) group of the present invention were treated with half the concentration of 0.25 μM taxol, 10 μM cisplatin and 5 μM etoposide. After 6 hours, the degree of cancer cell killing was confirmed by performing MTT analysis as in the above embodiment.
[0200] The results showed that for the control group transfected with small interfering RNA (siRNA) against BCL2 or BI-1, almost no cancer cell killing occurred, and only when treated with anticancer drugs did the cancer cell killing effect based on the anticancer drugs partially occur ( Figure 14 In contrast, the dual-target siRNA group 1 (si-BB1) of the present invention significantly killed cancer cells, and compared with the control group treated with both BCL2 siRNA and BI-1 siRNA, a synergistic increase in the cancer cell killing effect was confirmed even when used in combination with an anticancer agent at a significantly lower concentration ( Figure 14 Thus, it can be deduced that the dual-target siRNA of the present invention exhibits anticancer activity itself, and also exhibits specificity for the dual-target siRNA based on the synergistic effect of combined treatment with an anticancer agent.
[0201] 6-2-2. Comparison of the efficacy of Bcl2 inhibitors with small interfering RNA (siRNA) targeting both BCL2 and BI-1 fruit
[0202] The cancer cell killing inhibitory effects of the dual-targeting small interfering RNA (siRNA) targeting BCL2 and BI-1 (Group 1 si-BB1) of the present invention were compared with those of ABT-737, a cancer cell therapeutic agent based on BCL2 inhibition. Specifically, as in the above examples, LnCap cells, which are prostate cancer cells, were injected separately and then transfected with the siRNA Group 1 (si-BB1) targeting BCL2 and BI-1 of the present invention. The cells were then treated with 3 μM ABT-737 and cultured for 12 hours. The degree of cancer cell killing was then confirmed using an MTT assay.
[0203] The results showed that the cell death of LnCap cells increased after treatment with ABT-737 or the present invention's small interfering RNA (siRNA) group 1 (si-BB1) targeting BCL2 and BI-1. In particular, when ABT-737 and the present invention's dual-target small interfering RNA (siRNA) were treated together, the synergistic killing effect of cancer cells was significantly increased ( Figure 15 ).
[0204] 6-2-3. Comparison of BCL2 and BI-1 dual-targeting siRNAs and individual siRNAs Anticancer effects of siRNA
[0205] After culturing PC3 cell lines as human prostate cancer cell lines in 6-well plates, the dual-target small interfering RNA (siRNA) group 10 (si-BB1) of the present invention and each small interfering RNA (siRNA) for BCL2 or BI-1 in Table 13 as a control group were transfected, and after 48 hours, cisplatin was treated with 10 to 20 uM. After 12 hours of cisplatin treatment, 5 mg / mL of MTT (Promega, Ltd.) was treated to the cells and cultured for 4 hours. Afterwards, the culture medium was removed and 150 μl of solubilization solution and stop solution were treated, and cultured at a temperature of 37 ° C for 4 hours. The absorbance of the reaction solution was measured at 570 nm, and the cell survival rate was calculated using the above mathematical formula 1.
[0206] Table 13
[0207]
[0208] The results showed that compared with the control group that was not treated with cisplatin and treated with the control group siRNA, the group treated with the dual-target siRNA group 10 of the present invention and cisplatin showed a significant increase in cancer cell killing. Compared with the group treated with siRNA for BCL2 and BI-1 respectively, the degree of killing was significantly increased ( Figure 16).
[0209] 6-3. Combination of AR and mTOR dual-targeting small interfering RNA (siRNA) and anticancer drugs
[0210] DU145 and H460 cells were cultured in 6-well plates and transfected with the dual-target small interfering RNA (siRNA) set 16 (si-AT1) of the present invention. After 48 hours, the cells were treated with 50 μM cisplatin, 20 μM etoposide, or 1 μM taxol and cultured for 16 hours. Subsequently, the cells were treated with 5 mg / mL MTT (Promega, Ltd.) and cultured for 4 hours. The culture medium was then removed and treated with 150 μl of solubilization solution and stop solution, followed by incubation at 37°C for 4 hours. The absorbance of the reaction solution was measured at 570 nm, and cell viability was calculated.
[0211] The results showed that the dual-target small interfering RNA (siRNA) of the present invention alone caused cell killing in the DU145 cell line, which is a prostate cancer cell line (no anticancer drug treatment group (no treat)), and also caused cell killing in the cisplatin-treated group that did not show a cell killing effect. In addition, it was confirmed that the dual-target small interfering RNA (siRNA) group 16 (si-AT1) of the present invention significantly improved the DU145 cell killing effect by treating etoposide and paclitaxel, which showed slight anticancer activity. Figure 17 Part A). In addition, similar to the DU145 cell line, the dual-target small interfering RNA (siRNA) of the present invention exhibited a cell-killing effect on H460, a lung cancer cell line. When treated with etoposide and paclitaxel in combination, it was found to exhibit significant anticancer activity ( Figure 17 Part B of the

[0213] After the human telomerase reverse transcriptase (hTERT) promoter (SEQ ID NO: 74)-E1A (SEQ ID NO: 75)-internal ribosome entry site (SEQ ID NO: 76)-E1B sequence (SEQ ID NO: 77) (total sequence: SEQ ID NO: 78) was inserted between SpeⅠ and ScaⅠ of the adenovirus vector, the U6 promoter and the BCL2 and BI-1 dual-target short hairpin RNA (shRNA) (U6 promoter + BCL2 and BI-1 dual-target short hairpin RNA (shRNA) encoding sequence: SEQ ID NO: 79), mTOR and STAT3 dual-target short hairpin RNA (shRNA) (U6 promoter + mTOR and STAT3 dual-target short hairpin RNA (shRNA) encoding sequence: SEQ ID NO: 80) prepared in the above example were respectively inserted between SpeⅠ of the E3 region. The human telomerase reverse transcriptase (hTERT) promoter and dual-target short hairpin RNA (shRNA) sequence (U6 promoter + AR and mTOR dual-target short hairpin RNA (shRNA) coding sequence: SEQ ID NO: 81) were used to encode and express the human telomerase reverse transcriptase (hTERT) promoter and dual-target short hairpin RNA (shRNA), and infectious recombinant adenoviruses were prepared (BCL2 and BI-1 dual-target short hairpin RNA (shRNA) encoding and expressing adenovirus: CA101; mTOR and STAT3 dual-target short hairpin RNA (shRNA) encoding and expressing adenovirus: CA102; AR and mTOR dual-target short hairpin RNA (shRNA) encoding and expressing adenovirus: CA103; c-MET and PD-L1 dual-target short hairpin RNA (shRNA) encoding (expression) adenovirus: CA104) (refer to Figure 18 and Figure 19 Furthermore, as a control, a recombinant adenovirus (CA10G) containing only human telomerase reverse transcriptase (hTERT) was prepared. The sequences of the prepared adenoviral vectors were then analyzed, and if no abnormalities were detected, the viral genome was linearized using the PacI restriction enzyme. The resulting viruses were then transduced into 293A cells using the CACl2 method to produce the respective viruses.

[0218] The inhibitory effect of the recombinant adenovirus CA102 prepared in Example 7 on the expression of target genes mTOR and STAT3 was confirmed in bladder cancer cell lines. Specifically, T24 cells (0.5×10 5 / well) and 253JBV cells (1×10 5 After incubation at 4 °C for 1 hour, CA10G and CA102 were added to each well at an MOI of 10. After 72 hours, RNA was prepared using an RNA prep kit (Takara, 9767A). RNA was then quantified using a Nanodirp spectrophotometer. 400 ng / 20 μl of the premix was added to each tube using a real-time premix (Intron, 25081) and mixed uniformly with the premix. The mixture was then reacted using a polymerase chain reaction (PCR) instrument at 45°C for 1 hour and 95°C for 5 minutes to synthesize complementary deoxyribonucleic acid (cDNA). Using 2 μl of the synthesized complementary deoxyribonucleic acid (cDNA) as a template, a polymerase chain reaction (PCR) mixture (total volume 20 μl) was prepared for the experimental group (2 μl of template, 0.5 μl (10 pmoles / μl) of forward primer, 0.5 μl (10 pmoles / μl) of reverse primer, 10 μl of 2X master mix (Bioline, BIO-94005), and 7 μl of DW).
