[0115] The compound represented by formula (1a) above can be obtained by the method described in the Production Examples below or by an equivalent method.

3. Screening Method

[0116] Furthermore, the present invention includes an invention relating to a screening method for anti-cancer agents. In the screening method of the present invention, the RNA methylation inhibitory effects of test substances are measured by using cells or viruses.

[0117] The cells to be used are preferably cancer cells. The type of cancer is not particularly limited. Specific examples include pharyngeal cancer (e.g., lip cancer, gingival cancer, tongue cancer, oral cancer, oral floor cancer, and salivary gland cancer), gastrointestinal cancer (e.g., esophageal cancer, gastric cancer, appendiceal cancer, colon cancer, and rectal cancer), lung cancer, liver cancer, hepatocellular carcinoma, cholangiocarcinoma, bone cancer, articular cartilage cancer, malignant melanoma of the skin, spinocellular carcinoma, other skin cancers, mesothelioma, breast cancer, uterine cancer (e.g., cervical cancer, and endometrial cancer), ovarian cancer, prostate cancer, bladder cancer, brain tumor, thyroid cancer, non-Hodgkin's lymphoma, lymphocytic leukaemia, sarcoma, and cancers of metastatic tissue in which the aforementioned cancers are the primary tumors.

[0118] Specific cancer cells are not particularly limited, and cancer cells known in the cancer types mentioned above can be used. Of these, cancer stem cells are preferably used.

[0119] As the test substance, a low-molecular-weight compound is preferably used to measure methylation inhibition effects on the above cells or viruses, thus selecting a test substance with a desired level of inhibition.

[0120] In one preferred embodiment in the screening method of the present invention, examples of the method for measuring RNA methylation inhibitory effects include a method for measuring the activity of an enzyme that modifies RNA methylation, i.e., RNA methyltransferase. Wide variety of known RNA methyltransferases can be used. Specific examples include enzymes belonging to the ALKBH family and the Mettle family.

[0121] Of FTSJ, since FTSJ1 is considered to be a poor cancer prognostic factor, measuring the FTSJ1 inhibitory activity of the test substance in screening for anti-cancer agents is preferred.

[0122] The more specific method for measuring the activity of RNA methyltransferase is not particularly limited, and wide variety of known methods can be used. Examples include ELISA, RIA, immunoprecipitation, bisulfite, quantitative PCR, and reporter assay. Of these, the reporter assay is preferred because easy and accurate measurement is possible.

[0123] It is predicted that FTSJ1 performs 2′-O-methylatation of nucleotides at positions 32 and 34 of the tRNA corresponding to each of the polyglutamine (Q), phenylalanine (F), methionine (M), and asparagine (N) codons in mammalian cells.

[0124] In the reporter assay, the sequence of the translation regulatory region to which the reporter region is bonded preferably contains a sequence formed by the bonding of at least one member selected from the group consisting of glutamine, phenylalanine, tryptophan, methionine, and leucine.

[0125] The translation regulatory region is preferably a repeated sequence of each of the above five amino acids, i.e., polyglutamine, polyphenylalanine, polytryptophan, polymethionine, or polyleucine; or may be a sequence randomly containing these five amino acids. Further, the translation regulatory region may contain other amino acids to the extent that the function is not inhibited.

[0126] The size of amino acid tandem repeat is preferably 3 or more, more preferably 5 or more, and even more preferably 8 or more. The upper limit of the number of repeats is not particularly limited, and it can be set to 50.

[0127] Specific examples of such a translation regulatory region include sequences represented by SEQ ID Nos. 1 to 12. Examples include the sequence of SEQ ID No: 1 or 2 as polyglutamine, the sequence of SEQ ID No: 3 or 4 as polyphenylalanine, the sequence of SEQ ID No: 5 as polytryptophan, the sequence of SEQ ID No: 6 as polymethionine, and the sequences of SEQ ID No: 7 to 12 as polyleucine.

[0128] Furthermore, as a result of the research of the present inventors, YAP/TAZ is predicted to be a protein responsible for the nature of cancer stem cells, and whose protein synthesis is promoted by FTSJ1. Accordingly, in addition to the reporter assay in which the translation regulatory region is added to the reporter, it is also preferable to perform a reporter assay in which expression is regulated in the transcription factor binding region (GTIIC) that contains the sequence represented by SEQ ID No: 13, 3 to 15 times repeatedly (another sequence may be contained between each of the repeating units). In addition, sphere-formation assay and/or mass spectrometry are preferably performed.

[0129] Wide variety of known reporter genes can be used in the reporter assay without any particular limitation. Specific examples include a β-galactosidase gene, chloramphenicol acetyltransferase gene derived from bacterial transposon, and luciferase gene derived from Lucida cruciata. Of these, the luciferase gene derived from Lucida cruciata is preferably used because of its superior detection sensitivity.

[0130] Wide variety of known methods can be used as a method for linking the transcriptional regulatory region to the reporter gene, without any particular limitation. Specifically, a method in which the purified transcription sequence region is cleaved by a suitable limitation enzyme to link to the reporter gene, can be used.

[0131] As a vector for inserting the linked sequence, wide variety of known vectors for reporter assays, such as plasmids, shuttle vectors, and helper plasmids, can be used.

[0132] The method for transfecting the vector into cells is not particularly limited, and wide variety of known methods can be used. Examples include an electroporation method, spheroplast method, and lithium acetate method.

[0133] The luminescence intensity of the vector-transfected cells is measured using a luminometer according to a usual method. In the screening method of the present invention, it is preferable to measure the luminescence of solvents such as DMSO as a control group (blank) to calculate the assay value (%) of the test substance relative to the control group.

[0134] In the reporter assay in which the translation regulatory region containing a sequence formed by the bonding of at least one member selected from the group consisting of glutamine, phenylalanine, tryptophan, methionine, and leucine is added to a reporter, those having an assay value of preferably 100 or less, more preferably 80 or less, and even more preferably 40 or less can be selected by screening.

[0135] In the reporter assay in which the transcriptional regulatory region (GTIIC) represented by SEQ ID No: 13 is added to a reporter, those having an assay value of preferably 100 or less, more preferably 80 or less, and even more preferably 40 or less can be selected by screening.

[0136] Other embodiments include a screening method comprising the step of adding a methyl group donor to the test substance to obtain a reaction product, and the step of measuring the test substance using the reaction product.

[0137] Preferable examples of the methyl group donor include that can become a precursor of ATP as described below by desorbing the methyl group from the methyl group donor. Specific examples include S-adenosylmethionine (hereinafter simply referred to as “SAM”).

[0138] In the step of measuring the RNA methylation inhibitory effects against cells or viruses, ELISA, RIA, immunoprecipitation, bisulfite, quantitative PCR, reporter assay, and luciferase assay can be used.

[0139] In particular, when SAM is used as a methyl group donor in the step of adding the methyl group donor to the test substance, FTSJ1 contained in the test substance converts SAM into S-adenosylhomocysteine (hereinafter also referred to simply as “SAH”). Then, a reaction with a reagent that converts the obtained SAH into adenosine diphosphate (hereinafter also referred to simply as “ADP”) is performed to further add a predetermined reagent to ADP, thus obtaining adenosine triphosphate (hereinafter also referred to simply as “ATP”). By incorporating the obtained ATP into an assay system such as a luciferase assay, the activity of FTSJ1 in the test substance can be directly evaluated, which ensures highly accurate evaluation results.

4. Method for Predicting Efficacy of FTSJ1 Inhibitor Against Cancer, or Method for Predicting Prognosis

[0140] The present invention also comprises a method for predicting the efficacy of an FTSJ1 inhibitor against cancer, and a method for predicting the prognosis of cancer after the use of an FSTJ1 inhibitor. In the present specification, “prognosis” is defined as the medical outlook of a patient after chemotherapy.

[0141] The efficacy of the FTSJ1 inhibitor refers to the effect of the FTSJ1 inhibitor on cancer pathology. In other words, the method for predicting the efficacy of an FTSJ1 inhibitor according to the present invention includes the concept of the method for predicting the sensitivity to an FTSJ1 inhibitor of a cancer patient, or the concept of the method for predicting the sensitivity to an FTSJ1 inhibitor of cancer tissues or cells collected from a cancer patient. The method for predicting the efficacy of an FTSJ1 inhibitor according to the present invention includes the concept of the method for predicting the resistance to an FTSJ1 inhibitor of a cancer patient, or cancer tissues or cancer cells collected from a cancer patient.

[0142] The method for predicting the efficacy of an FTSJ1 inhibitor against cancer, or method for predicting prognosis after the use of an FTSJ1 inhibitor against cancer according to the present invention comprises step A of measuring the FTSJ1 expression level in a sample.

[0143] Cancer tissues or cancer cells derived from living organisms (including humans and animals) can be used as a sample. Specifically, cancer tissues or cancer cells collected from patients (cancer patients) can be used.

[0144] The FTSJ1 expression level can be measured by a wide variety of known methods without limitation. The immunological method and the genetic method can both be preferably used.

[0145] There is no particular limitation on the immunological method, and examples include ELISA, inmunostaining, flow cytometry, and immunoblotting.

[0146] There is no particular limitation on the genetic method, and examples include western blotting and RT-PCR.

[0147] The method for predicting the efficacy of an FTSJ1 inhibitor against cancer, or method for predicting prognosis after the use of an FTSJ1 inhibitor against cancer according to the present invention further comprises, after step A, step B for determining the efficacy of the FTSJ1 inhibitor against cancer, or for determining the prognosis of cancer pathology of the patient, based on the FTSJ1 expression level obtained in step A.

[0148] In particular, in step B, setting the predetermined cutoff value of the FTSJ1 expression level in the sample obtained in step A is preferred. For example, in predicting the efficacy of an FTSJ1 inhibitor, a sample whose expression level obtained in step A is above the cut-off value is predicted to have high FTSJ1 efficacy, whereas a sample with an expression level below the cut-off value is predicted to have low FTSJ1 efficacy.

[0149] Similarly, in the method for predicting the cancer pathogenesis of the patient after the use of an FTSJ1 inhibitor as well, for a sample whose expression level obtained in step A is above a predetermined cut-off value, patient prognosis is predicted to be good after the use of the FTSJ1 inhibitor; whereas for a sample with an expression level below the cut-off value, patient prognosis is predicted to be poor after the use of an FTSJ1 inhibitor.

[0150] The method for predicting the efficacy of an FTSJ1 inhibitor against cancer, or method for predicting the prognosis of cancer after the use of an FTSJ1 inhibitor according to the present invention can be widely used in known cancers, without any particular limitation. Specific examples include glioblastoma (malignant brain tumor), pancreatic cancer, acute myeloid leukemia, lung cancer, liver cancer, kidney cancer, gastric cancer, and breast cancer.

5. Marker for Determining Efficacy of Anti-Cancer Agent

[0151] The present invention also comprises the invention relating to a marker for determining the efficacy of an anti-cancer agent. The marker is a gene marker: an FTSJ1 inhibitor sensitivity-related gene marker and an FTSJ1 inhibitor resistance-related gene marker.

[0152] The sensitivity to an FTSJ1 inhibitor of the patient can be determined by whether these markers are detected from samples (tissues or cells) collected from patients (including humans and animals). The detection of an FTSJ1 inhibitor sensitivity-related gene marker from a sample suggests that the FTSJ1 inhibitor is effective for the patient in chemotherapy. On the other hand, the detection of an FTSJ1 inhibitor resistance-related gene marker from a sample suggests that the FTSJ1 inhibitor is not effective for the patient in chemotherapy.

[0153] These markers for determining the efficacy of an anti-cancer agent relating to FTSJ1 (FTSJ1 inhibitor sensitivity-related gene marker or FTSJ1 inhibitor resistance-related gene marker) are preferably FTSJ1-modified nucleic acid RNAs.

[0154] The FTSJ1 inhibitor resistance-related gene marker is preferably at least one member selected from the group consisting of AHNAK2 (SEQ ID No: 14), ESYT1 (SEQ ID No: 15), SRGAP1 (SEQ ID No: 16), RHOF (SEQ ID No: 17), MIR4746 (SEQ ID No: 18), UBXN6 (SEQ ID No: 19), COX16 (SEQ ID No: 20), FTH1 (SEQ ID No: 21), LPAR1 (SEQ ID No: 22), ANKRD29 (SEQ ID No: 23), TWIST2 (SEQ ID No: 24), JKAMP (SEQ ID No: 25), PRKAA2 (SEQ ID No: 26), CSTF2T (SEQ ID No: 27), THSD4 (SEQ ID No: 28), MAGI1 (SEQ ID No: 29), UBE2L3 (SEQ ID No: 30), GPLD1 (SEQ ID No: 31), FRYL (SEQ ID No: 32), and MYO9A (SEQ ID No: 33).

[0155] The FTSJ1 inhibitor sensitive-related gene marker is preferably at least one member selected from the group consisting of RBM15, SEQ ID No: 34), NASP (SEQ ID No: 35), PRPF38A (SEQ ID No: 36), C1orf50 (SEQ ID No: 37), PEX16 (SEQ ID No: 38), ZNF213 (SEQ ID No: 39), FEM1B (SEQ ID No: 40), RFXAP (SEQ ID No: 41), SAP18 (SEQ ID No: 42), AARS2 (SEQ ID No: 43), RCC2 (SEQ ID No: 44), YARS1 (SEQ ID No: 45), RBM10 (SEQ ID No: 46), RPL5 (SEQ ID No: 47), ZNHIT2 (SEQ ID No: 48), OSGIN2 (SEQ ID No: 49), EGLN3 (SEQ ID No: 50), TRPTI (SEQ ID No: 51), CRACDL (SEQ ID No: 52), CAPG (SEQ ID No: 53), RAB11FIP3 (SEQ ID No: 54), CALHM5 (SEQ ID No: 55), BICD1 (SEQ ID No: 56), and FTSJ1 (SEQ ID No: 57).

6. Kit for Predicting Efficacy of FTSJ1 Inhibitors

[0156] The present invention also includes a kit comprising the marker for determining the efficacy of anti-cancer agents. If at least one of the above FTSJ1 inhibitor resistance-related gene markers is detected in the sample, the FTSJ1 inhibitor is determined to not be effective in the chemotherapy of patients.

[0157] In contrast, if at least one of the FTSJ1 inhibitor sensitivity-related gene markers is detected in the sample, the FTSJ1 inhibitor is determined to be effective in the chemotherapy of patients.

[0158] The kit is not particularly limited as long as it uses a mechanism of detecting the gene marker in a sample. In an embodiment, for example, cDNA is obtained from a sample, and amplified by PCR to detect the gene marker. In this case, the kit of the present invention preferably contains a primer for each genetic marker for performing PCR.

[0159] The embodiments of the present invention are explained above; however, the present invention is not limited thereto. The present invention can be performed in various forms as long as these forms do not depart from the gist of the present invention.

EXAMPLES

[0160] The embodiments of the present invention are described in more detail based on Examples. However, the present invention is not limited to these Examples.

Experimental Examples

Screening

[0161] Human gastric cancer cell line NUGC3 was cultured in a DMEM medium (high glucose with L-glutamine and phenol red, produced by FUJIFILM Wako Pure Chemical Corporation) containing 10% fetal bovine serum (produced by Thermo Fisher Scientific Inc.) and penicillin-streptomycin (produced by FUJIFILM Wako Pure Chemical Corporation) (this medium is simply referred to below as “DMEM+10% FBS+1×P/S”). Then, the NUGC3 cells were seeded in a 60-mm culture dish (produced by BioLite) so that the cells were 80% confluent after 24 hours. Subsequently, 5 μg of a reporter plasmid and 15 μL of a lipofection reagent (transIT-LT1, produced by Mirus Bio LLC) were mixed in 500 μL of Opti-MEM medium (produced by Thermo Fisher Scientific, Inc.) to form a complex, which was added to the medium in which the NUGC3 cells were cultured in the 60-mm culture dish. For use as the reporter plasmid, 5 μg of a polyglutamine luciferase reporter was introduced (in the polyglutamine luciferase reporter, a Renilla luciferase expressed in the IRES was located as an internal standard downstream of the sequence of a firefly luciferase sequence to which polyglutamine was added). Alternatively, a YAP/TAZ activity reporter was used by simultaneously introducing 3 μg of 8×GTIIC plasmid and 2 μg of a Renilla luciferase reporter as an internal standard. After another 24 hours, the cells were exfoliated with a 0.05 w/v % trypsin-0.53 mmol/l EDTA-4Na solution (produced by FUJIFILM Wako Pure Chemical Corporation), and then seeded in a 96-well plate (produced by BioLite) so that the cells were 80% confluent after 24 hours. Twenty-four hours after seeding in the 96-well plate, the medium in each well was replaced with 100 μL of a medium (DMEM+10% FBS+an antibiotic) containing 10 μM or 5 μM of a compound for evaluation. After another 24 hours, the medium containing the compound was removed, and the 96-well plate was transferred on ice. Each well was washed with 100 μL of phosphate buffer (PBS, produced by FUJIFILM Wako Pure Chemical Corporation). Thereafter, 20 μL of Passive Lysis Buffer (1×) contained in a Dual-Luciferase Reporter Assay System (produced by Promega Corporation) was added. The plate was then gently shaken for 15 minutes at room temperature to lyse the cells. After confirming that the cells were lysed, 10 μL of the lysate was transferred from each well to each corresponding well of a white 96-well plate (produced by Greiner Bio-one). To each well of the white 96-well plate was added 100 μL of a mixture of a Luciferase Assay Buffer II and Luciferase Assay Substrate contained in the Dual-Luciferase Reporter Assay System (produced by Promega Corporation), whereby the luminescence of the firefly luciferase was induced, and the luminescence intensity was detected with a microluminometer (produced by Berthold Japan K.K.). Subsequently, 100 μL of a mixture of Stop & Glo Buffer and Stop & Glo Substrate contained in the Dual-Luciferase Reporter Assay System (produced by Promega Corporation) was added, whereby the luminescence of firefly luciferase was quenched while the luminescence of Renilla luciferase was induced, and the luminescence intensity was detected with a microluminometer (produced by Berthold Japan K.K.) in a manner similar to the above. The ratio of the luminescence intensity of the firefly luciferase and the luminescence intensity of the Renilla luciferase was calculated, and the luminescence intensity (%) of the wells containing each compound was calculated with the luminescence intensity of the well containing DMSO (dimethyl sulfoxide, used as a solvent for the compound liquids) taken as 100%. Table 1 below shows the results of inhibition of each compound. Unless otherwise specified, the measured values in the table represent the results obtained by evaluation with the addition of 10 μM of each compound for evaluation.

Screening Test

[0162] HEK293 human embryonic kidney cells that constantly express FLAG-tagged FTSJ1 were produced, and from its cell lysate, FLAG-FTSJ1 was separated by adsorption using an anti-FLAG M2 antibody affinity gel (Sigma-Aldrich Co. LLC, catalog number: A2220-10ML), and eluted with FLAG peptide (Sigma-Aldrich Co. LLC, catalog number: F3290-25MG). After measuring the protein concentration in the eluate, serial dilutions were performed within the range of 0 to 20 ng/reaction to obtain enzyme dilutions of 12 different concentrations. Further, the total RNA was extracted from HEK293-FTSJ1-KO cells, in which FTSJ1 was knocked out, using TRIzol Reagent (Thermo Fisher Scientific Inc., catalog number: 15596018). In order to measure the activity which FLAG-FTSJ1 caused transmethylation with RNA as a substrate, the enzyme dilutions, the total RNA (1,000 ng/reaction), and a methyltransferase activity assay kit (Promega Corporation, catalog number: V7601) were used. The conversion reaction from SAM (s-adenosyl methionine) to SAH (s-adenosyl homocysteine), which occurred when FLAG-FTSJ1 in each dilution methylated 1,000 ng/reaction of the total RNA, was measured as a luciferase luminescence value using MTase-Glo Reagent in the assay kit. Taking the luminescence value at the time when FLAG-FTSJ1 was 0 ng as a background value, a graph was drawn using the numerical values obtained by subtracting the background value from the luminescence value at each dilution step. As shown in FIG. 3A, a dose-dependent increase in the luminescence value of FLAG-FTSJ1 was observed, confirming that detecting the enzyme activity of FTSJ1 was possible.

[0163] Using the above system, the inhibitory effect of transmethylation by PVZF2001, which is an FTSJ1 inhibitor, was confirmed. The luminescence values were measured as described above by mixing different concentrations of PVZF2001 dilutions with the use of 10 ng/reaction of FLAG-FTSJ1, 1,000 ng/reaction of the total RNA, and the methyltransferase activity assay kit. As shown in FIG. 3B, a decrease in the luminescence value was observed in a concentration-dependent manner of PVZF2001, confirming that PVZF2001 certainly inhibited transmethylation caused by FTSJ1.

Anti-Tumor Effect Evaluation Test

[0164] A cell suspension (1×10.sup.6 cells/100 μL), in which triple-negative breast cancer cell line MDA-MB-231 was suspended in phosphate buffer (PBS, produced by FUJIFILM Wako Pure Chemical Corporation), was inoculated subcutaneously in the dorsal lumbar region of immunodeficient mice (BALB/c-nu/nu, female, 6 weeks old, purchased from Shimizu Laboratory Supplies Co., Ltd.) using a syringe with a 23 G injection needle (Terumo Corporation). After confirming that the cancer cells engrafted under the skin of the mice to form tumor tissues, and that the tumor volume reached 100 mm.sup.3, the obtained tumor model mice were used for the following evaluation test. First, each compound for evaluation was dissolved in corn oil (produced by Sigma-Aldrich Co., LLC) and administered intraperitoneally. PVZF0024 was administered at 100 mg/kg and PVZF2001 was administered at 20 mg/kg to the tumor model mice every other day. At each administration, the tumor diameter was measured with a caliper. The tumor volume was calculated according to the following formula: V=(3.14×D×d.sup.2)/6 (wherein V is the tumor volume, D is the tumor major axis, and d is the tumor minor axis) (Wu. et al., Clin. Cancer Res., 2013 Oct. 15; 19(20): 5699-5710).

[0165] FIGS. 1 and 2 show the antitumor effects of PVZF0024 and PVZF2001. As shown in each figure, both of the compounds were confirmed to significantly inhibit tumor growth; additionally, no weight loss due to administration was observed.

Test for Evaluating FTSJ1 Inhibitor Sensitive Genetic Marker

[0166] In order to extract genes that prescribe the sensitivity and resistance with respect to the FTSJ1 inhibitors, PVZF2001 was used to proceed with the analysis with a cell line panel (JFCR39). Each of 39 types of human cancer cell lines was treated with PVZF2001 at concentrations of 0.01 μM, 0.1 μM, 1 μM, 10 μM, and 100 μM for 48 hours, and cell proliferation was measured by colorimetric quantification with sulforhodamine B. FIG. 4A shows the obtained Log GI50 values. The GI50 value is defined, based on the number of cells before drug exposure, as a concentration at which the increase is inhibited by 50% by drug treatment, with the increase in a sample cultured for 48 hours without drug treatment (negative control) taken as 100%. In order to extract the target gene clusters, a COMPARE analysis was first performed using gene expression and the Log GI50 values in all of the cell lines. The gene clusters of SEQ ID NOs: 14 to 28 were then identified as FTSJ1 inhibitor resistance-related genetic markers, while the gene clusters of SEQ ID NOs: 34 to 47 were identified as FTSJ1 inhibitor sensitive-related genetic markers. Furthermore, focusing on the malignant brain tumors and the lung cancers in which clearly distinguishable sensitivity and resistance by PVZF2001 were observed, gene expression data of the cell lines with high sensitivity (e.g., U251, SF-539, SNB-75, NCI-H522, DMS114) and the cell lines with high resistance (e.g., SNB-78, NCI-H23) were each used to analyze gene clusters that underwent increased expression in each of the cell lines in common. The gene clusters of SEQ ID NOs: 29 to 33 were then identified as FTSJ1 inhibitor resistance-related genetic markers, while the gene clusters of SEQ ID NOs: 48 to 56 were identified as FTSJ1 inhibitor sensitive-related genetic markers. Using these genetic markers, a database of gene expression information (TCGA) obtained from patient samples was analyzed. Patients with a high FTSJ1 gene expression level showed a high expression level of the FTSJ1 inhibitor sensitive-related genetic markers; conversely, patients with a low FTSJ1 gene expression level showed a high expression level of FTSJ1 inhibitor resistance-related genetic markers. That is, the results reveal that the FTSJ1 gene expression level itself also represents sensitivity and resistance with respect to the FTSJ1 inhibitors (SEQ ID NO: 57).

[0167] To verify whether the expression analysis of these gene clusters contributes to predicting the anti-cancer effect by the FTSJ1 inhibitors, the FTSJ1 gene was actually used as an example to analyze the anti-cancer effect of the FTSJ1 inhibitor PVZF2001 on human malignant brain tumor cell lines. Human malignant brain tumor cell lines MGG4, MGG8, MGG18, MGG23 were treated with stem cell medium (Neurobasal, B-27, N-2, 20 ng/mL EGF, 20 ng/mL bFGF) containing different concentrations (0 nm, 200 nM, 500 nM, 1000 NM, 2000 NM, 5000 nM) of PVZF2001 for 1 week, and anchorage-independent cell proliferation was evaluated based on sphere-forming ability. As a result, as shown in FIG. 4B, MGG4, MGG8, and MGG18, which showed a high FTSJ1 expression level, showed proliferation inhibition at low concentrations of PVZF2001; whereas MGG23, which showed a low FTSJ1 expression level, showed cell proliferation even when treated at a concentration as high as 2000 NM.
