Biomarker refers to an index that can detect changes caused inside living organisms due to external influences, and is used to diagnose various diseases such as cancer, stroke, and dementia, or to predict or monitor the efficacy of specific treatments. Is becoming more active. As biomarkers related to drug development, the efficacy test marker (Pharmacodynamic marker; PD marker) to confirm the action of the drug in vivo, and the efficacy predictive marker that can be administered by predicting the reactivity of the drug before in vivo administration (Predictive marker). The use of these markers helps to establish clinical strategies for drugs.For example, markers for predicting efficacy that are expected to be effective through the action of drugs can be used in the patient selection process to enable more effective drug treatment, and efficacy verification markers In this case, it is necessary to monitor whether the drug is working well in individual patients so that more effective treatment strategies can be established. In addition, even in the absence of an efficacy predictive marker, an individual patient's response to a drug in drug treatment can be monitored more early if an efficacy assay marker is present, so early screening of the group showing the efficacy of the drug and the group without the efficacy of the drug And, consequently, more effective and successful drug treatment. In addition, the effect verification marker can be used as an index for calculating an appropriate dose of a drug by monitoring the degree of drug reactivity according to the dose concentration.

Meanwhile, cancer is one of the major causes of death to date. With the development of medical technology, there is a noticeable change in cancer treatment technology, but the 5-year survival rate has only improved by 10% over the past 20 years. This can be said to be because it is difficult to diagnose and treat at an appropriate time due to characteristics such as rapid growth and metastasis of cancer. By introducing an appropriate biomarker into cancer treatment, it is possible to increase the chance to use an appropriate therapeutic agent in a timely manner by grasping the characteristics of cancer, thereby greatly increasing the success rate of cancer treatment. For example, even in the same lung cancer patient, the characteristics of each lung cancer classification, gene, and secreted protein are different, and accordingly, suitable treatments are different. Therefore, in chemotherapy using a specific therapeutic agent, if a biomarker corresponding to the therapeutic agent exists, it is possible to reduce trial and error and increase the probability of success. For this purpose, it is very important to search for biomarkers for predicting or assaying the efficacy of an anticancer drug, and if an appropriate biomarker is successfully derived, the effectiveness and value of the anticancer drug and the success rate of the treatment using the same can be greatly increased.

On the other hand, c-Met is a receptor for hepatocyte growth factor (HGF), and HGF binds to the extracellular site of the c-Met receptor tyrosine kinase to divide, exercise, and form in various normal and tumor cells. It is a type of cytokine that causes angiogenesis. c-Met is a representative receptor tyrosine kinase that exists on the cell surface. It is a cancer-causing gene. Sometimes, regardless of the ligand HGF, cancer occurs, cancer metastasis, cancer cell migration, cancer cell invasion, and neovascularization. Since it is involved in various mechanisms related to tumors such as, etc., it is a protein that is attracting attention as a target for anticancer treatment in recent years, and target therapeutics such as antibodies that inhibit the action of c-Met are being developed.

In order to further enhance the efficacy of the treatment using the c-Met target treatment developed as described above and increase the probability of success, the efficacy of the treatment is predicted or tested to select patients suitable for application of the treatment and monitor the reactivity after administration of the treatment. Development of biomarkers that can be applied to establish more effective treatment strategies is required.

TFF1 (Trefoil factor 1) is a substance expressed and secreted in the digestive tract, and its expression has been reported to increase in colorectal cancer, lung cancer, pancreatic cancer, prostate cancer, breast cancer, etc., but the relationship between c-Met protein and TFF1 has been reported to date. none.

In an example of the present invention, the reactivity to the c-Met inhibitor is different depending on the expression level of TFF1, and the difference in the expression level of TFF1 before and after treatment with the c-Met inhibitor depends on the reactivity to the c-Met inhibitor. Revealed that it will be different. More specifically, when the level of TFF1 or the gene encoding it in a biological sample is low, the efficacy is well exerted when a c-Met inhibitor, such as an anti-c-Met antibody, is applied to the biological sample or the patient from which the biological sample is derived. It can be confirmed that it is. In addition, when resistance is induced against a c-Met inhibitor, such as an anti-c-Met antibody, it can be confirmed that the level of TFF1 or a gene encoding the same increases.

That is, by measuring the expression level of TFF1, the efficacy of the c-Met inhibitor is predicted to select a suitable target to apply the c-Met inhibitor, or the change in the expression level of TFF1 according to whether or not c-Met inhibitor is treated or before and after treatment is measured. By doing so, it can be usefully used to determine whether to obtain resistance to the c-Met inhibitor and/or to monitor the efficacy of the inhibitor to determine whether or not to continuously apply the c-Met inhibitor. Based on this, for the first time, the usefulness of TFF1 as a biomarker for predicting the efficacy and/or assaying the efficacy of a c-Met inhibitor is proposed.

The "c-Met protein" refers to a receptor tyrosine kinase that binds to hepatocyte growth factor. The c-Met protein may be derived from all species, for example, human c-Met (eg, NP_000236), monkey c-Met (eg, Macaca mulatta, NP_001162100) derived from primates, or mouse c- Met (eg, NP_032617.2), rat c-Met (eg, NP_113705.1) and the like may be derived from rodents. The protein includes, for example, a polypeptide encoded by the nucleotide sequence provided in GenBank Aceession Number NM_000245, or a protein encoded by the polypeptide sequence provided in GenBank Aceession Number NM_000236, or an extracellular domain thereof. Receptor tyrosine kinase c-Met is involved in various mechanisms, such as cancer development, cancer metastasis, cancer cell migration, cancer cell penetration, and angiogenesis process.

C-Met, a receptor for Hepatocyte growth factor (HGF), is divided into three parts: an extracellular site, a transmembrane site, and an intracellular site. In the case of the extracellular site, α- and β-subunits are separated by disulfide bonds. In a linked form, it consists of an HGF binding domain, the SEMA domain, the PSI domain (plexin-semaphorins-integrin homology domain), and the IPT domain (immunoglobulin-like fold shared by plexins and transcriptional factors domain). The SEMA domain of the c-Met protein may have the amino acid sequence of SEQ ID NO: 79, and is a domain present in the extracellular site of c-Met and corresponds to a site to which HGF binds. In the SEMA domain, a region having an amino acid sequence of SEQ ID NO: 71 corresponding to a specific site, for example, 106th to 124th, is a loop between the 2nd and 3rd propeller domains of the epitopes in the SEMA domain of the c-Met protein. Corresponds to the site, and can act as an epitope of the anti-c-Met antibody proposed in the present invention.

The term “epitope” is an antigenic determinant and is interpreted to mean a portion of an antigen recognized by an antibody. According to one embodiment, the epitope is a region containing 5 or more consecutive amino acids in the SEMA domain (SEQ ID NO: 79) of the c-Met protein, such as the 106 th in the SEMA domain (SEQ ID NO: 79) of the c-Met protein. It may include 5 to 19 consecutive amino acids located in SEQ ID NO: 71 corresponding to the 124th to. For example, the epitope may be composed of 5 to 19 consecutive amino acids including SEQ ID NO: 73 (EEPSQ) among the amino acid sequence of SEQ ID NO: 71, for example, the amino acid sequence of SEQ ID NO: 71, SEQ ID NO: 72 or SEQ ID NO: 73 It may be a polypeptide having.

The epitope having the amino acid sequence of SEQ ID NO: 72 corresponds to the outermost region of the loop region between the domains of the 2nd and 3rd propeller structure in the SEMA domain of the c-Met protein, and the amino acid sequence of SEQ ID NO: 73 The epitope possessed is a site to which the antibody or antigen-binding fragment according to an embodiment most specifically binds.

Therefore, the anti-c-Met antibody may specifically bind to an epitope comprising 5 to 19 consecutive amino acids including SEQ ID NO: 73 (EEPSQ) among the amino acid sequence of SEQ ID NO: 71, for example, sequence It may be an antibody or antigen-binding fragment that specifically binds to an epitope having the amino acid sequence of SEQ ID NO: 71, SEQ ID NO: 72, or SEQ ID NO: 73.

Animal-derived antibodies produced by immunizing a desired antigen to an immunized animal can generally cause an immune rejection reaction when administered to humans for therapeutic purposes, and a chimeric antibody has been developed to suppress this immune rejection reaction. Chimeric antibodies are those obtained by substituting a constant region of an animal-derived antibody that causes an anti-isotype reaction with a constant region of a human antibody using a genetic engineering method. Chimeric antibodies are significantly improved in anti-isotype response compared to animal-derived antibodies, but animal-derived amino acids are still present in the variable regions, implying side effects for potential anti-idiotypic reactions. Are doing. Humanized antibodies were developed to improve these side effects. This is produced by grafting a CDR (complementaritiy determining regions) region that plays an important role in antigen binding among the variable regions of a chimeric antibody into a human antibody framework.

The most important thing in the CDR grafting technology for producing humanized antibodies is to select an optimized human antibody that can best accept the CDR regions of an animal-derived antibody, and for this purpose, the use of an antibody database and crystal structure structure) and molecular modeling techniques are used. However, even if the CDR regions of an animal-derived antibody are transplanted into the optimized human antibody skeleton, there are cases where amino acids that are located in the skeleton of the animal-derived antibody and affect antigen binding are present. Therefore, it can be said that the application of additional antibody engineering techniques to restore antigen binding capacity is essential.

According to one embodiment, the antibody may be a mouse-derived antibody, a mouse-human chimeric antibody, a humanized antibody, or a human-derived antibody. The antibody may be isolated from a living body.

A complete antibody has two full-length light chains and two full-length heavy chains, and each light chain is linked to a heavy chain by a disulfide bond. The constant region of an antibody is divided into a heavy chain constant region and a light chain constant region, and the heavy chain constant region has gamma (γ), mu (μ), alpha (α), delta (δ) and epsilon (ε) types, and subclasses It has gamma 1 (γ1), gamma 2 (γ2), gamma 3 (γ3), gamma 4 (γ4), alpha 1 (α1) and alpha 2 (α2). The constant region of the light chain has kappa (κ) and lambda (λ) types.

The term “heavy chain” refers to a variable region domain V _H and three constant region domains C _H1 , C _H2 and C _H3 comprising an amino acid sequence having a sufficient variable region sequence to confer antigen specificity and a hinge ( hinge), and its fragments. In addition, the term "light chain" refers to both the full-length light chain and fragments thereof comprising the variable region domain V _L and the constant region domain C _L comprising an amino acid sequence having a sufficient variable region sequence to confer antigen specificity. It is interpreted to mean including.

The term "complementarity determining region (CDR)" refers to an amino acid sequence of a hypervariable region of an immunoglobulin heavy and light chain. Each of the heavy and light chains may comprise three CDRs (CDRH1, CDRH2, CDRH3 and CDRL1, CDRL2, CDRL3). The CDRs may provide key contact residues for the antibody to bind to an antigen or epitope. On the other hand, in the present specification, the terms "specifically bind" or "specifically recognize" are the same as those commonly known to those skilled in the art, and the antigen and antibody specifically interact to cause an immunological reaction. Means that.

The term "antigen-binding fragment" refers to a fragment thereof for the entire structure of an immunoglobulin, and refers to a portion of a polypeptide including a portion to which an antigen can bind. In one embodiment, the antigen-binding fragment may be scFv, (scFv) ₂ , Fab, Fab' or F(ab') ₂ , but is not limited thereto. Among the antigen-binding fragments, Fab has a structure having a variable region of a light chain and a heavy chain, a constant region of a light chain, and a first constant region of a heavy chain (C _H1 ), and has one antigen-binding site.

Fab' differs from Fab in that it has a hinge region containing at least one cysteine residue at the C-terminus of the heavy chain C _H1 domain.

F(ab') ₂ antibodies are produced by disulfide bonds between cysteine residues in the hinge region of Fab'. Fv is the smallest antibody fragment having only a heavy chain variable region and a light chain variable region. Recombination techniques for generating an Fv fragment are well known in the art.

The double-chain Fv (two-chain Fv) is a non-covalent bond where the heavy chain variable region and the light chain variable region are connected, and the single-chain Fv (single-chain Fv) is generally shared by the variable region of the heavy chain and the variable region of the single chain through a peptide linker. It is linked by a bond or is directly linked at the C-terminus to form a dimer-like structure such as a double-chain Fv. The peptide linker may be a polypeptide consisting of 1 to 100 or 2 to 50 arbitrary amino acids, and the type of amino acid contained therein is not limited.

The antigen-binding fragment can be obtained using proteolytic enzymes (e.g., Fab can be obtained by restriction digestion of the whole antibody with papain, and F(ab') ₂ fragment can be obtained by digestion with pepsin), It can be produced through gene recombination technology.

All subtypes of immunoglobulins (e.g., IgA, IgD, IgE, IgG (IgG1, IgG2) except for the above-defined CDR regions or light chain variable regions and heavy chain variable regions of the anti-c-Met antibody. , IgG3, IgG4), IgM, etc.) and heavy chain constant regions.

The term "hinge region" is a region included in the heavy chain of an antibody, exists between the CH1 and CH2 regions, and refers to a region that functions to provide flexibility of an antigen binding site in the antibody.

When an animal-derived antibody undergoes a chimerization process, the animal-derived IgG1 hinge is replaced with a human IgG1 hinge, but the animal-derived IgG1 hinge is shorter than that of the human IgG1 hinge, and the disulfide bond between the two heavy chains ( disulfide bond) decreases from 3 to 2, resulting in different effects of the rigidity of the hinge. Therefore, modification of the hinge region can increase the antigen binding efficiency of the humanized antibody. Methods for deletion, addition or substitution of amino acids to modify the amino acid sequence of the hinge region are well known to those skilled in the art.

Thus, in one embodiment of the present invention, in order to enhance the antigen-binding efficiency, the anti-c-Met antibody or antigen-binding fragment includes a hinge region in which one or more amino acids are deleted, added or substituted, and the amino acid sequence is modified. I can. For example, the antibody is a hinge region having the amino acid sequence of SEQ ID NO: 100, SEQ ID NO: 101, SEQ ID NO: 102, SEQ ID NO: 103, or SEQ ID NO: 104, or a hinge region having the amino acid sequence of SEQ ID NO: 105 (unmodified human hinge Area) may be included. More specifically, the hinge region may have an amino acid sequence of SEQ ID NO: 100 or SEQ ID NO: 101.

The present invention relates to the development of a method for predicting the efficacy of an anti-c-Met antibody using TFF1 expression. Through the present invention, the following effects can be expected.

1) Whether the anti-c-Met antibody will show efficacy can be predicted by checking the expression of the TFF1 gene in the patient's cancer tissue. This can be used as a predictive marker and contribute to the selection of applicable patient groups, thereby increasing the clinical success rate. Ultimately, in the concept of personalized medicine, c-Met targeting therapy can minimize unnecessary treatment to patients and enable treatment that maximizes the effect.

2) Whether or not anti-c-Met antibody will show efficacy can be predicted by measuring the TFF1 level in the blood. Since TFF1 is a secretory protein, it can be measured by blood collection.

3) It can be confirmed whether resistance of the anti-c-Met antibody is induced through periodic measurement of TFF1. Through such resistance monitoring, the treatment potential can be increased by adjusting the cycle and method of treatment with anti-c-Met antibodies. Since TFF1 is a secretory protein, it can be measured in blood, so it has the advantage that it can be easily monitored by methods other than biopsy.

4) In cancer types in which resistance of the anti-c-Met antibody is induced and the anti-c-Met antibody alone does not show an effect, a remarkable anti-cancer effect can be seen by co-administration of a TFF1 inhibitor with an anti-c-Met antibody. -Met antibody efficacy can be improved or resistance can be overcome.

1.1.1. Immunization of mice

In order to obtain the immunized mice required for the development of hybridoma cell lines, 5 mice were treated with 100 µg of human c-Met/Fc fusion protein (R&D Systems) and the same amount of complete Freund's adjuvant. Were mixed and injected into the abdominal cavity of 4-6 week old BALB/c mice (Japan SLC, Inc.). After two weeks, 50 µg, half of the amount previously injected with the human c-Met/Fc fusion protein used as the antigen, was mixed with the same amount of incomplete Freund's adjuvant in the same manner as above, It was injected intraperitoneally. One week later, the last boosting was performed, and 3 days later, blood was collected from the tail of the mouse to obtain serum, and diluted in PBS at 1/1000 to confirm that the titer of the antibody recognizing c-Met was increased by ELISA. As a result of the above, mice for which sufficient amount of antibody was obtained were selected to perform the following cell fusion process.

1.1.2. Cell fusion and Hybridoma Produce

3 days before the cell fusion experiment, a human c-Met/Fc fusion protein mixture was injected in 50 µg of PBS into the abdominal cavity of BALB/c mice (Japan SLC, Inc.), and the immunized mouse was anesthetized on the left side of the body. The located spleen was excised. The extracted spleen was ground with a mesh to separate cells, and mixed with a culture medium (DMEM, GIBCO, Invitrogen) to prepare a splenocyte suspension. The suspension was centrifuged to recover the cell layer. The obtained splenocytes 1× ^{10 8} and myeloma cells (Sp2/0) 1× ^{10 8} were mixed, and then centrifuged to precipitate the cells. The centrifuged precipitate was slowly dispersed, treated with 45% (w/v) polyethylene glycol (PEG) (1 mL) contained in a culture medium (DMEM), and maintained at 37° C. for 1 minute, and then the culture medium (DMEM) 1 ml was added. Thereafter, 10 ml of the culture medium (DMEM) was added for 1 minute, left to stand in water at 37° C. for 5 minutes, and then centrifuged again to 50 ml. The cell precipitate was resuspended in a separation medium (HAT medium) at about 1 to 2×10 ⁵ /ml, and 0.1 ml each was dispensed into a 96-well plate, and then cultured in a carbon dioxide incubator at 37°C to prepare a hybridoma cell group.

1.1.3. Selection of hybridoma cells producing monoclonal antibodies against c- Met protein

In the hybridoma cell group prepared in Reference Example 1.1.2, a human c-Met/Fc fusion protein and a human Fc protein were used as antigens to select hybridoma cells that react specifically only to the c-Met protein. Screened through ELISA analysis method.

To the microtiter plate, 50 µl (2 ug/ml) of human c-Met/Fc fusion protein was added to each well and attached to the plate surface, and unreacted antigens were washed away. Human Fc protein was attached to the plate surface in the same manner as above in order to select and exclude antibodies that bind to Fc other than c-Met.

50 µl of the hybridoma cell culture solution obtained in Reference Example 1.1.2 was added to each well and reacted for 1 hour, and then sufficiently washed with a phosphate buffer-Tween 20 (TBST) solution to remove the unreacted culture solution I did. To this, goat anti-mouse IgG-horseradish peroxidase (goat anti-mouse IgG-HRP) was added to react at room temperature for 1 hour, and then sufficiently washed with TBST solution. Subsequently, a substrate solution (OPD) of peroxidase was added and reacted, and the degree of reaction was confirmed by measuring the absorbance at 450 nm with an ELISA Reader.

By confirming the degree of reaction as described above, hybridoma cell lines that do not bind to human Fc and secrete antibodies having high binding ability specifically only for human c-Met protein were repeatedly selected. The hybridoma cell line obtained through repeated selection was subjected to limiting dilution to finally obtain a clone of one hybridoma cell line producing a monoclonal antibody. On October 6, 2009, the final selected monoclonal antibody-producing hybridoma was deposited with the Korea Cell Line Research Foundation, located in Yeongeon-dong, Jongno-gu, Seoul, Korea, which is an international depository under the Budapest Treaty, and was granted accession number KCLRF-BP-00220 (Korea See Patent Publication No. 2011-0047698).

1.1.4. Production and purification of monoclonal antibodies

The hybridoma cells obtained in Reference Example 1.1.3 were cultured in a serum-free medium, and monoclonal antibodies were produced and purified from the culture medium.

First, the hybridoma cells cultured in 50 ml of a culture medium (DMEM) containing 10% (v/v) FBS were centrifuged and the cell precipitate was washed twice or more with 20 ml PBS to remove FBS. , The cell precipitate was resuspended in 50 ml of a culture medium (DMEM) medium, and then cultured in a carbon dioxide incubator at 37° C. for 3 days.

Thereafter, the cells were centrifuged to remove the antibody-producing cells, and the culture medium in which the antibodies were secreted was separated, stored at 4°C or collected immediately and used for separation and purification of the antibody. After purely purifying the antibody from 50 mL to 300 mL of the prepared culture medium using an AKTA purification device (GE Healthcare) equipped with an affinity column (Protein G agarose column; Pharmacia, USA), a filter for protein aggregation (Amicon) was used. Using PBS, the supernatant was replaced to store the purified antibody and used in the following examples.

In these cell lines, 5000 NCI-H1395 (ATCC, CRL-5868), NCI-H1437 (ATCC, CRL-5872), HCI-H2110 (ATCC, CRL-5924) were used to measure anticancer efficacy against anti-c-Met antibodies. , NCI-H2122 (ATCC, CRL -5985), NCI-H2126 (ATCC, CCL-256), and an anti-c-Met EBC1 antibodies exhibit efficacy (JCRB, JCRB0820) cells and each dispensed in 96-well plate , After 24 hours, the antibody (L3-1Y/IgG2) was treated in an amount of 0 ug/ml, 0.016 ug/ml, 0.08 ug/ml, 0.4 ug/ml, or 2 ug/ml. 72 hours after antibody treatment, cell number change was measured through CellTiter Glo assay (Promega, G7573). This method measures the amount of ATP that reflects the metabolism of living cells. In the CellTiter Glo assay, a substrate that releases luminoscence when reacting with ATP in cells is added. By measuring this luminoscence, the number of living cells can be quantified. The results are shown in FIG. 1. As shown in FIG. 1, it can be seen that none of the tested lung cancer cell lines except EBC1 showed the effect of inhibiting cancer cell growth by L3-1Y/IgG2.

To determine whether there is a correlation between the TFF1 expression level and anti-c-Met antibody efficacy, the EBC1 cell line already known to be effective for L3-1Y/IgG2 and 5 lung cancer cell lines that did not show efficacy (NCI-H1395 , NCI-H1437, NCI-H2110, NCI-H2122 and NCI-H2126). The expression level measurement consisted of measuring the mRNA level, and the expression level was measured using the following primer.

sense, 5'-cccctggtgcttctatccta-3' (SEQ ID NO: 109);

antisense, 5'-gatccctgcagaagtgtctaaaa-3' (SEQ ID NO: 110).

QPCR for measuring the expression level consists of cell seeding, RNA extraction, cDNA synthesis, and qPCR reaction. First, to extract RNA, cells were dispensed at a concentration of 10^6 cells/plate in 60 mm dishes and cultured for 2 days. After 2 days, RNA was extracted using the RNeasy Mini kit (Qiagen, #74106), and when RNA was extracted, it was extracted in 50 ul of RNase free DW. Of these, 2-3 ug of RNA is synthesized into cDNA using the Transcriptor First Strand cDNA synthesis kit (Roche, #04 896 866 001). At this time, it follows manufacture's protocol. For pPCR reaction, LC480 SYBR Green I Master (Roche, #04　887　352　001) and LightCycler® 480 Real-Time PCR System (Roche) were used. GAPDH was used as an internal control for correcting the amount of RNA in the sample, and qPCR was performed according to the following procedure for all primers. Step1: 95°C, 10 min; Step2 (45 cycles): Step 2-1: 95°C, 10 sec; Step 2-2: 60° C., 20 sec; Step 2-3: 72°C, 20 sec; Step3: 95° C., 5 sec; Step4: 65 DEG C, 1 min; Step5: 95°C, continuous (every 5°C); Step6: 40℃, 10 sec.

Fig. 2 shows the obtained results. 2 is a result of measuring the TFF1 level through qPCR. When expressed as the difference between the Ct values of TFF1 and HPRT1, the higher the value, the lower the expression level. As shown in FIG. 2, it can be seen that the L3-1Y/IgG2 effect was not shown in the case of the lung cancer cell line, the TFF1 level was significantly higher than that of EBC1, which was effective.

Example 2. 　 term c- Met In gastric cancer cell lines in which resistance to antibodies was induced TFF1 Expression level measurement and anti c- Met Measurement of inhibition of cancer cell growth against antibodies

In order to measure how the TFF1 expression level changes when resistance is induced by repeated administration of anti-c-Met antibody, the MKN45 gastric cancer cell line in which resistance to L3-1Y/IgG2 antibody was induced by repeated administration of L3-1Y/IgG2 was used. The manufacturing process of the resistance-obtaining MKN45 gastric cancer cell line is as follows: MKN45 cells (JCRB, JCRB0254) were treated with L3-1Y antibody for more than 3 months while increasing the throughput. The throughput of the L3-1Y/IgG2 antibody was increased from the initial treatment concentration of 1 ug/ml to 10 ug/ml until resistance appeared. In order to confirm the acquisition of L3-1Y/IgG2 antibody resistance, the L3-1Y/IgG2 antibody was added to the resistant clone at 0 ug/ml, 0.016 ug/ml, 0.08 ug/ml, 0.4 ug/ml, or 2 ug/ml. It was treated with sheep, and 72 hours after antibody treatment, cell number change was measured through CellTiter Glo assay (Promega, G7573).

Fig. 3 shows the obtained results. Figure 3 shows the L3-1Y/IgG2 resistant MKN45 clones #6 and #7 (hereinafter referred to as MKN45-re#6, #7) and #1 and #24 (hereafter MKN45-re#1, # 24) as a graph showing the reactivity to L3-1Y/IgG2, it can be seen that the L3-1Y/IgG2 antibody shows efficacy in MKN45 cells, but does not show efficacy in cells in which resistance is induced.

A qPCR experiment was performed to see the difference in TFF1 levels between MKN45 cells and MKN45-resistant clones. The experimental method is the same as in Example 1.

Fig. 4 shows the obtained results. Figure 4 shows the level of the TFF1 transcript, expressed as a relative amount to MKN45 cells. As can be seen in Figure 4, it can be seen that the TFF1 level is significantly increased in MKN45-#6, #7, #1, and #24 in which resistance is induced. This suggests that TFF1 predicts the reactivity of L3-1Y/IgG2.

In addition, in order to confirm whether the TFF1 siRNA treatment can overcome the resistance obtained due to the repeated treatment of the antibody, an experiment was conducted to treat the siRNA in MKN45-re#24 cells. GAPDH siRNA (Dharmacon, Cat.No. D-001830-01) was used as a control, and TFF1 siRNA (Dharmacon, Cat.No. L-003715-01-0005) was used as the target siRNA. First, 0.3 ul RNAiMax and 40 nM of siRNA were added to a 96 well plate and incubated at room temperature for 15 minutes. At this time, RNAiMax and siRNA were diluted in Opti-MEM and the total volume of the mixture was 25 ul. 80 ul of MKN45-re#24 cells diluted with RPMI1640 medium (GIBCO) containing 10% FBS so that 5000 cells per well per well were seeded in this 96 well. After 24 hours of transfection, the existing medium was removed, and the antibody was treated by adding 100 ul of the medium diluted with the L3-1Y/IgG antibody. At this time, the antibody throughput was set to 0, 0.016, 0.08, 0.4, or 2 ug/ml. 72 hours after antibody treatment, cell number change was measured through CellTiter Glo assay (Promega, G7573).

Fig. 5 shows the obtained results. As shown in FIG. 5, when the L3-1Y/IgG2 antibody and TFF1 siRNA were treated in combination, it was confirmed that the cancer cell growth inhibitory effect that was not found in the L3-1Y/IgG2 antibody alone treatment was shown. This suggests that the acquired resistance of the anti-c-Met antibody can be overcome through TFF1 inhibition.

Example 3. Item c- Met In lung cancer cell lines in which resistance to antibodies was induced TFF1 Expression level measurement and anti c- Met Measurement of antibody's inhibitory effect on cancer cell growth

When resistance is induced in the lung cancer cell line, to measure the change in TFF1 expression, the EBC1 lung cancer cell line (JCRB, JCRB0820) was treated with L3-1Y/IgG2 antibody for at least 3 months to obtain a cell line that obtained resistance to L3-1Y/IgG2 antibody. Was used. The EBC1 lung cancer cell line obtained resistance to the L3-1Y antibody was prepared with reference to Example 2. In order to confirm the acquisition of L3-1Y/IgG2 antibody resistance, the L3-1Y/IgG2 antibody was added to the resistant clone at 0 ug/ml, 0.016 ug/ml, 0.08 ug/ml, 0.4 ug/ml, or 2 ug/ml. It was treated with sheep, and 72 hours after antibody treatment, cell number change was measured through CellTiter Glo assay (Promega, G7573).

Fig. 6 shows the obtained results. FIG. 6 is a graph showing the reactivity of L3-1Y/IgG2 resistant EBC1 clones #14 and #20 (hereinafter EBC1-re#14, #20) induced resistance to L3-1Y/IgG2, with EBC1 cells Alternatively, it can be seen that the L3-1Y/IgG2 antibody does not show efficacy in EBC1 cells in which resistance is induced.

In addition, TFF1 mRNA was extracted from EBC1 cells and EBC1-re#14 and #20 by referring to the methods of Example 1 and Example 2 to confirm the TFF1 level. The results are shown in FIG. 7. Figure 7 shows the level of the TFF1 transcript, expressed as a relative amount to EBC1 cells. As can be seen in FIG. 7, it can be seen that the level of TFF1 increased when resistance to L3-1Y/IgG2 was obtained in the lung cancer cell line EBC1, similar to the gastric cancer cell line in Example 2.

In addition, in order to confirm whether TFF1 siRNA treatment can overcome the resistance obtained due to the repeated treatment of the antibody, an experiment was conducted in which siRNA was co-treated with the antibody in EBC1-re#20 cells. 8 shows the results of measuring the number of cells by treating TFF1 siRNA with reference to the method of Example 2. Similar to the results obtained in Example 2, even in the EBC1 lung cancer cell line in which resistance was induced, when the L3-1Y/IgG2 antibody and TFF1 siRNA were treated in combination, the cancer cell growth inhibitory effect that was not found in the L3-1Y/IgG2 antibody alone treatment was shown. Could be confirmed. This suggests that the acquired resistance of the anti-c-Met antibody can be overcome through TFF1 inhibition.

Example 4. Xenograft mouse model Using serum of mine TFF1 Protein level measurement

In order to show that TFF1 can function as a marker for anti-c-Met antibody even at the protein level, the level of TFF1 protein in serum was measured.

For this, a xenograft model transplanted with patient-derived lung cancer cells was used. Each patient-derived lung cancer cell was transplanted into a mouse to create a xenograft mouse model in which patient-derived cancer cells (lung cancer cells) were transplanted (Oncotest GmbH, Freibrug Germany). Patient-derived lung cancer cells (Non-Small Cell Lung Cancer (NSCLC)) LXFA289, LXFA 400, LXFA 1848, and LXFA 2158 cells were injected into NMRI nude mice (4-6 weeks old, female; Harlan) as sc to create a xenograft mouse model. I did. The fabrication method followed the Oncotest SOP "Subcutaneous implantation" method. 10 mice were used per group.

When the tumor size reached ~2000 mm ³ , mouse serum was obtained, where the TFF1 protein level was measured. In order to minimize individual differences between mice, ELISA was performed using serum from individuals whose tumor size belongs to median in each group. For ELISA, Human Trefoil factor 1 ELISA kit (EIAab, E1049h) was used. First, 1 ml of Sample Diluent was added to the standard to make a 10.0 ng/ml stock standard solution, and then diluted by 1/2 to prepare a standard. Mouse serum was also diluted by 1/2 with Sample Dilent. 50 ul of standard, blank, and diluted serum were added to each well, and 50 ul of Detection A solution was added thereto. The plate was shaken to mix well, and then incubated at 37°C for 1 hour. After 1 hour, the solution inside was discarded and washed 3 times with Wash Buffer (included in ELISA kit (EIAab, E1049h)). The washing process was performed by adding Wash Buffer in an amount of 300 to 400 ul, leaving for 1 to 2 minutes, and then removing the solution. 100 ul of Detection Reagent B solution was added and left at 37°C for 45 minutes, followed by washing 5 times with Wash Buffer. After washing, 90 ul of Substrate Solution was added and left at 37℃ for 15~30 minutes. At this time, the light did not enter. When the appropriate color came out, 50 ul Stop Solution was added and the absorbance was measured at 450 nm.

The concentration determined by substituting the measured absorbance into the standard is shown in FIG. 9. In the mouse serum of the xenograft model transplanted with patient-derived lung cancer cells, it can be confirmed that TFF1 is measured in the detectable range (0.15-10.0 ng/ml), suggesting that the TFF1 protein can be applied as a soluble marker. In FIG. 9, LXFA2158 is a c-Met inhibitor (L3-1Y/IgG2) efficacious group, and the rest are ineffective groups, and as a result of this, the efficacy group when the TFF1 protein is used as a marker under the above experimental conditions and The concentration criterion of the TFF1 protein capable of distinguishing the ineffective group may be set to about 3 to about 3.5 ng/ml.TFF1 protein (e.g., when the TFF1 protein is about 3 to about 3.5 ng/ml or less, the efficacy group, the above range Higher than the ineffective group).

Example 5. c- Met Level and TFF1 To identify target patients with a combination of levels of

In addition to TFF1, it was tested that the mRNA levels and/or protein levels of c-Met could be used for selection of patients to which c-Met inhibitors were applied either independently or with TFF1.

Xenograft tumor samples (requested by Oncotest GmbH, Freibrug Germany) of 8 lung adenocarcinoma were tested using affymetrix U133Plus 2.0.

The capture and prep of mRNA followed the U133 Plus 2.0 standard protocol (http://www.affymetrix.com/estore/browse/products.jsp?productId=131455#1_3/3'; IVT Express Kit User Manual (pdf, 1.17). MB)). Quantile normalization (Bolstad, BM, Irizarry RA, Astrand, M, and Speed, TP (2003) A Comparison of Normalization Methods for High Density Oligonucleotide Array Data Based on Bias and Variance.Bioinformatics 19(2) ), pp 185-193) to correct the expression value, and then obtain the expression value of the gene of TFF1 (Affymetrix probe id: 205009_at). In addition to the DNA chip used in this example, the gene expression of TFF1 may be replaced by other experimental methods by those of ordinary skill in the art to which this invention belongs.

Fig. 10 shows the obtained results. In FIG. 10, each dot represents a patient, the x-axis represents the mRNA expression level of the c-Met gene, and the y-axis represents the mRNA expression level of the TFF1 gene. The blue dots represent the anti-c-Met inhibitor (L3-1Y/IgG2) efficacy group, the black dots and the red dots represent the anti-c-Met inhibitor (L3-1Y/IgG2) ineffective group, and the gray dots represent data. It shows the case of absence (n=1163). If the expression level of c-Met is high, the efficacy of the c-Met inhibitor is expected, but if the boundary between the effective group and the ineffective group is difficult to discriminate due to variables such as patient group and experimental equipment, information on the expression level of TFF1 When used together, more accurate patient group discrimination can be expected.
