Description
PROCESS TO PRODUCE THE OSEA MORFONGENETIC PROTEIN. BY MATURATION
Technical area
The present invention presents a process for producing bone morphogenetic protein by maturation. More specifically, this invention presents a process for the production of a bone morphogenetic protein by maturation, which includes inducing the action of a processing enzyme on a bone morphogenetic protein precursor.
Background of the Invention
The existence of a proteinaceous bone morphogenetic factor in the matrix bone was discovered by ürist et al. (Science, 150, pp. 893-899, 1965) and was termed "bone morphogenetic protein" (which will be abbreviated hereinafter as "BMP"). "). In recent years, many genes related to BMP have been cloned and each of them is known as belonging to the super family of the transforming growth factor-ß. (which will be abbreviated here as "TGF-ß"). From some of them, recombinant proteins have already been produced. They have been used for the confirmation of bone morphogenetic activity
REF .: 28647 and its application is expected in the treatment of bone diseases-
The proteins previously described supposedly correspond each of them to the TGF-β super family, from its genetic structure, until it is synthesized as a precursor in vivo and then subjected to several processes, from a maturation (active type) of peptide or odimer. The maturation of human TGF-ßl is known to be a dimer of the peptide residue with COOH terminal 112 (Nature, 316, 701-705, 1985). In practice, it is known that in mammalian cells, the introduction of a coding cDNA precursor, to produce BMP-2 or BMP-6 / Vgr-1 incorporates, in addition to the maturation of the dimer peptide, various peptides dimers (ho odimers). compounds of high molecular weight and heterodimeric monomers composed of high molecular weight monomers and a maturing monomer) having a higher molecular weight than the more mature ones in the culture supernatant (Growth Factors 7, pp. 139-150, 1992 : J. Biol. Chem. 126, pp. 1595-1609, 1994). These dimer peptides have a higher molecular weight than the maturation ones that are supposed to correspond to the low-processing molecules from the precursor of maturation. The dimeric peptide having a higher molecular weight than the maturing one will henceforth be called a "precursor dimer". Technically, it is very difficult to produce it selectively, among the various dimers described above, a dimer peptide of a certain molecular weight, for example a large-scale maturing dimer; or by efficiently carrying out the separation of the maturation dimer. Accordingly there is a strong demand to overcome such technical difficulty.
Exhibition of the Invention
An objective of the present invention is to provide an efficient method to selectively produce, in a mammalian cell, a maturation dimer of the same molecular weight as the mixture of dimers of various precursor molecular weights of a large-scale bone morphogenetic protein.
In recent years, a group of proteases similar to Kex2, F rina, PC-2, PC-3, PACE4, PC6 and the like were identified as processing enzymes in contrast to the precursor of a protein in a higher animal (Biochem. 299, pp. 1-18, 1994). Among them, furine has a hydrophobic transmembrane region in the terminal COOH and locally exists in the Golgi membrane. The cDNA sequence encoding human furin has already been reported by van den Ouweland et al. (Nucleic Acids Res. 18, pp.
664, 1990). It has been revealed that furin recognizes Arg-X? -X2-Arg (where XI represents any amino acid and X2 represents any amino acid, but mainly Lys or
Arg) as a 4 amino acid sequence upstream from its division site (J. Biol. Chem. 266, pp. 12127-12130,
1991). It has also been reported that when only the NH2 terminal region of furin without the transmembrane region is expressed in a mammalian cell, it is secreted outside the cell and the specific activity of cleaving the amino acid sequence remains the same at the site of secretion.
(J. Biol. Chem. 269, pp. 25830-25837, 1994).
The inventors hereby, for the first time, achieved in efficient large-scale production, in a mammalian cell, of only one maturation dimer without a precursor dimer by the use of the above-described furin based on recombinant DNA technology.
According to the present invention, a bone morphogenetic protein by maturation can be produced by inducing the action of a processing enzyme on a bone morphogenetic protein precursor.
According to the present invention, the processing enzyme is acting on the bone morphogenetic protein precursor by introducing both, an expression vector of the bone morphogenetic protein precursor and an expression vector of the processing enzyme in the mammalian cell strain. The cell strain is cultured and then, from the supernatant culture, the bone morphogenetic protein is obtained by maturation.
According to the present invention, the processing enzyme acts on the bone morphogenetic protein precursor by the addition of a processing enzyme containing the supernatant culture in a supernatant culture containing precursors of the bone morphogenetic proteins. Bone morphogenetic protein by maturation is produced by incubation of the resulting mixture.
Preferably, the production is carried out by introducing both a vector expression of a human MP52 precursor and an expression of the mutant secretory furin vector into a mammalian cell strain, culturing the cell strain and then, separating the supernatant culture from the culture supernatant. bone morphogenetic protein by maturation thus produced.
The term "bone morphogenetic protein by maturation" as used herein means a bone morphogenetic protein that is substantially composed of a sequence of homologous amino acids with amino acid residues COOH-terminal 112 of human active type TFG-ßl. The activity of the bone morphogenetic protein is assumed to exist in the homologous region of the amino acid sequence with amino acid residue with terminal COOH 112 of this human TGF-ßl active type as desired, the bone morphogenetic protein does not contain the other region of the amino acid sequence.
Examples of the processing enzymes usable in the present invention include a group of proteases similar to Kex2, furin, PC-2, PC-3, PACE4 and PC6. Among them, furine is particularly preferred. As the cDNA encoding furin, the DNA of the base sequence encoding the entire amino acid sequence of furin can be used, but the DNA of the base sequence encoding a portion of the amino acid sequence (which will be called from here "mutant furin type .secretory") that does not include a tansmembrane region and also maintains specific activity of division in the amino acid sequence.
In the preferred embodiment of the present invention, a DNA fragment containing a secretory mutant furin cDNA is cloned from a total RNA extracted from human HepG2 cell strains (ATCC HB8065) by the RT-PCR method using a synthesized DNA primer. The secretory mutant furin has, as its base sequence DNA, from nucleotide No. 163 to nucleotide No. 2014 placed forward in SEQ ID NO: 1 of the Sequence Listing. This DNA fragment is inserted into a vector expression by which an expression of the secretory mutant furin vector is constructed. The term "vector" used herein contains, at the lower end of the eukaryotic promoter, a poly (A) -added which indicates which is a restriction enzyme site for cloning a gene for expression. This expression vector may also contain a drug-resistant marker favorable for the selection of a transformant. Examples of such vector expression include a human cytomegalovirus promoter enhancer, polylinker, poly (A) - bovine growth hormone as signal addition and pRc / CMV (available from INVITROGEN Inc.) containing a resistant neomycin marker.
The present invention is applicable to a method of producing a bone morphogenetic protein belonging to the human TGF-β superfamily, more specifically, to the method of producing a morphogenetic bone protein by maturation composed of monomers having the same molecular weight, example, MP52, BMP-2, BMP-4, BMP-6 or BMP-7. As a bone morphogenetic protein, human MP52 which is presented in PCT Application WO93 / 16099 or O95 / 04819 and has bone morphogenetic activity which is particularly preferred. In a preferred embodiment, the cDNA encoding a human MP52 precursor is inserted into a vector expression to construct the expression of the human MP52 precursor vector, followed by introduction into a mammalian cell, whereby the cell line is prepared of mammals that produce the precursor and the MP52 dimer of maturation. Examples of mammalian cells adapted as host cells here include Chinese hamster ovary (CHO) cells, BHK cells, 293 cells and mouse L cells. Among them, CHO cells are preferred. In the line of human MP52 produced mammalian cells (MC-2: FERM declaration number BP-5142) thus obtained, expression of the secretory mutant furin vector is introduced to co-express both proteins, whereby they are only produced MP52 dimers maturation in their culture supernatant.
The conversion of the precursor protein in its maturation form can also be achieved by mixing a solution containing the processing enzyme with precursor containing solution and incubating the resulting mixture overnight at 32 to 40 ° C, preferably 37 ° C.
The bone morphogenetic protein by maturation available by the process of the present invention can be used for the treatment or prevention of damage to bones, cartilage or teeth or for roots of artificial teeth by adding it to pharmaceutically acceptable vehicles, additives, diluents and / or excipients such as be necessary.
For the treatment of bone diseases caused by malfunction of bone metabolism, bone morphogenetic protein by maturation can be administered in any conventional manner systemically and carefully, for example, injections such as intravenous injection, intramuscular injection or intraperitoneal injection, oral administration or parenteral administration such as suppository.
For the treatment of bone fractures, morphogenic protein by maturation can be administered systemically or locally by injection, oral administration or parenteral administration. Also preferred is the implantation of a matrix or template containing the morphogenetic protein by maturation in a region close to the fractured bone. Suitable examples of the matrix include natural polymers such as collagen or adhesive fibrin and synthetic polymers such as a copolymer of polylactic acid and glycolic acid.
In the case of orthopedic reconstructions, bone grafts or roots of artificial teeth, bone morphogenetic protein by maturation can be applied on the surface of the bone or tooth to be implanted, being covered with a paste of collagen, adhesive fibrin or other adhesive. In the case of bone grafts, it can be used for both natural and artificial bones.
The dose of bone morphogenetic protein by maturation is determined based on the purpose and method of administration. In general, the dose is 1 μg to 100 μg / Kg. in systemic administration, while it is preferably 30 μg to 30 mg. / place in local administrations.

Description of preferred modalities
The advantages of the present invention hereinafter will be described more specifically by examples.
Example 1
The production of the human MP52 maturation dimer by CHO cell lines that co-express a human secretory mutant furin and human MP52.
(1) Cloning of the mutant furin cDNA type secretory human and construction of its vector expression.
The human furin protein has a structure composed of a peptide signal, a protease region similar to sub-lysine, a transmembrane region and a lateral region of cytoplasm in the order mentioned from the terminal NH2 region. In this invention, human secretory mutant furin cDNA encoding cDNA from the NH2-terminal protease region without the transmembrane region was cloned by the RT-PCR method and provided for expression.
The total RNA was extracted from the human HepG2 cell and with this as the standard, the primer 1 in upward sense (human furin cDNA sequences Nos. 931 to 914 located forward of SEQ ID NO: 1 of the List of
Sequences) and primer 2 in contra-sense down
(Nos .. 2095 to 2071) was subject to reverse transcription by rTth RNA polymerase. These products in combination with primer 3 in the sense (SEQ ID NO: 2 of the Sequence Listing) and the primer 4 in contrasense (SEQ ID NO: 3 of the Sequence Listing), and with primer 5 in the sense (SEQ ID NO: 4 of the Sequence Listing) and primer 6 in contrasense (SEQ ID NO: 5 of the Sequence Listing) were subjected to PCR reaction, respectively, whereby two cDNA fragments were obtained at the upper and lower ends. These fragments were pooled and inserted into the HindIII-SalI site of plasmid pUC119 (obtained from Takara Shuzo Co., Ltd.), whereby the cDNA of the secretory mutant human furin encoding 595 amino acids was obtained. The resulting cDNA was confirmed by restriction enzyme digestion and determination of a DNA base sequence. The cDNA of the human secretory mutant furin was found to have, as the base DNA sequence, nucleotides Nos. 163 through 2014 of SEQ ID NO: 1 of the Sequence Listing. The DNA sequence of this human secretory mutant furin is different from the DNA sequence reported by van der Ouweland et al., In which this base No. 165 is adenine so that an initiation codon that supposedly has an adverse effect on the translation and is therefore unnecessary, has been eliminated; and in this the base No. 2004 is adenine so that a stop codon was formed. Then the human secretory mutant furin cDNA was removed by digestion with HindIII-Xbal, followed by insertion in the HindlII-Xbal site of the pRc / CMV vector purchased from INVITROGEN INC., So pDfurpRC / CMB, an expression was prepared of the cDNA of the human secretory mutant furin as illustrated in Fig. 1.
(2) Construction of the vector expression of human MP52.
From the plasmid pSK52s containing the human MP52 gene provided by Dr. Hoetten of Biopharm GmbH, a DNA fragment containing the human MP52 gene isolated by digestion with HindIII, followed by insertion in the HindIII site of the vector pABstop provided by Dr. Zettl eissl from Behringwerke AG, by means of pMSS99, an expression of the human MP52 vector as illustrated in FIG. 2. Its structure was confirmed by the determination of the DNA base sequence and digestion with a restriction enzyme. As a result the human MP52 of the DNA base sequence of pMSS99 was found to be nucleotides Nos. 576 to 2279 of SEQ ID NO: 6 of the Sequence Listing.
(3) Establishment of MC2, that is, a Chinese Hamster Ovary cell line (CHO) that produces several precursors of human MP52 dimers.
In CHO-DÜKX-B11 cells provided by Dr.
Zettl eissl from Behringwerke AG, that is, mutant strains of CHO cells, pMSS99 and pSVOAdhfr provided by Dr. Zettlmeissl was introduced by the calcium phosphate co-precipitation method of DNA. Then, a high production of the human MP52 cell line was established by the method of gene amplification using methotrexate (MTX).
pMSS99 (10 μg.) and pSVOAdhfr (2 μg.) were dissolved in 1 ml. of 25 mM HEPES, 140 mM NaCl and 0.75 mM NaaHP0 (pH 7.05) and followed. mix with 50 μl. of 2.5 M of Ca CI2. The precipitate was stored on CHO-DUKX-B11 cells in 10 cm dishes. and it was kept at room temperature for 30 mins. To the cell layer was added 8 ml. of ribo- and deoxyribonucleotide containing MEM-ALPHA medium
(MEM-a +), containing 10% fetal calf serum and the resulting mixture was cultured for 4 to 6 hours in a CO2 incubator. Following the treatment with 10% glycerol at room temperature for 3 minutes, the cells were cultured in a MEM-a + medium containing 10% FBS. The cultured cells were then inoculated again in a medium of free ribo- and deoxyribonucleotide MEM-ALPHA (MEM-a-) containing 10% dialyzed FBS and the transformant was selected. The production of human MP52 was detected by Western blot analysis as described below in (5).
In the production medium of human MP52 cell strains, MTX was added. By successive increase of the MTX concentration, cell lines having the amplified MP52 gene were selected. In the 400 nM concentration of MTX, the production of the precursor cell line MC-2 of the human MP52 dimers of various molecular weights and the human MP52 maturation dimer was obtained. The resulting MC-2 cell line was deposited in "National Institute of Bioscience and Human Technology, Agency of Industrial Science and Technology (1-3, Higashi 1-chome, Tsukuba-shi, Ibaraki-ken) on June 21, 1995 under the Deposit number of FERM BP-5142.
(4) Establishment of the coexpression of the human MP52 cell line and the human secretory mutant furin by the introduction of the expression vector of the human secretory mutant furin in the human MP52 producing CHO of the MC-2 cell line.
The co-expression of the human MP52 cell line and the human secretory mutant furin was established by introduction of the vector expression of the human secretory mutant furin in the CHO of the MC-2 cell line which produced several precursors of MP52 dimers. human and maturation dimers MP52 by the calcium phosphate co-precipitation method of the DNA and then select the transforming cell in the presence of 333 μg / ml. of G418 and 400 nM. of MTX.
In a manner similar to Example 1 (2), the calcium phosphate co-precipitate of the DNA was formed using pDfurpRC / CMV (4.8 μg.). The MC-2 cells were then stored in 10-cm dishes, and kept at room temperature for 30 minutes. To the cell layer, 8 ml was added. of a free ribo- and deoxyribonucleotide medium MEM-ALPHA (MEM-a-) containing 10% FBS and the resulting mixture was cultured for 4 to 6 hours in a CO2 incubator. After treatment with 10% glycerol at room temperature for 3 minutes, the cells were cultured on a MEM-a-medium containing 10% FBS for 2 days. The cultured cells were again inoculated in MEM-a medium containing 10% FBS, 400 nM MTX and 333 μg / ml. of G418 and the transformant strains were selected. The production of human MP52 was detected by Western blot analysis as described below in (5). The production of human secretory mutant furin was detected by the method of measurement of enzymatic activity as described below (6). Free serum from one of the supernatant cultures of the co-expression of the cell lines resulting from the human MP52 furin and the human secretory mutant furin was subjected to the daily exchange medium and the supernatants collected were subjected to SDS-polyacrylamide electrophoresis under recutting conditions and then analyzed by Western staining. The results are shown in the photo of Fig. 3. At each stage, a 0.5 μl portion of the culture supernatant was emptied. Stages 1, stage 2, and stage 3 are supernatant cultures of Day 1, Day 2, and Day 3 respectively. The MP52 monomer band of maturation is indicated by an arrow. It was found that the MP52 precursor did not have a large molecular weight detected in the supernatant and all the MP52 were peptides with a molecular weight of approximately 15 K, which corresponds to the maturing monomers MP52. as a result of an analysis under non-reducing conditions, these peptides formed the maturing MP52 dimers each having a molecular weight of approximately 28 K. The amount of production of the dimers by use of the cell co-expression line was approximately 8. μg / 24 hours, which was approximately 3 to 8 times as well as by the use of the MP52 expressing cell of the MC-2 line. Thus by the use of the human MP52 co-expression line and the human secretory mutant furin, the present inventors were successful for the first time in the production of MP52 maturation dimers only on a larger scale than conventional methods.
(5) Detection of human MP52 in the culture supernatant by Western blot analysis
Proteins from the culture supernatant were separated by electrophoresis through SDS-polyacrylamide gel
(15-25% polyacrylamide gel gradient, Dalichi Kagaku Co., Ltd.) followed by transfer of the protein to a PVDF Membrane P membrane for clear staining). The membrane was blocked with "Block Ace" (Dainippon Pharmaceutical Co.,
Ltd.) for one hour, rinsed with Tris saline regulator
(TBS) and then treated overnight with 10 μg / ml. of chicken antibodies in contrast to human MP52. The membrane was washed with TBS, containing 0.1% Tween 20
(TTBS) and followed by treatment with an antipollo IgG and rabbit alkaline phosphatase complex (Sigma A9171). The membrane was rinsed with TTBS and the band corresponding to MP52 was visualized by means of the alkaline phosphatase substrate kit (BIO-RAD).
(6) Detection of the activity of human secretory mutant furin in the culture supernatant Twenty μl. of the supernatant culture were diluted by 30 μl of pure water and mixed with 200 μl of a phosphorescent substrate solution; incubate with 125 mM of MES / NaOH (pH 7.0) containing 100 mM of Boc-Arg-Arg-Val-Arg-MCA (purchased from Protein Technology Institute) and 1.25 mM of CaCl2 at 37 ° C for 10 minutes. The fluorescence of AMC was measured at an excitation wavelength of 380 nm and an emission wavelength of 450 nm. Thus the furina activity unit was defined as, the activity necessary for the release of 1 pCM per minute. (OR) .
(7) MP52 purification of maturation produced by co-expression with human secretory mutant furin and analysis of the NH2 terminal amino acid sequence.
With serum free from the supernatant culture of the co-expression of the human MP52 cell strain and the human secretory mutant furin, 0.1 volume by volume of 0.2 M sodium phosphate buffer (pH 6) was mixed. The resulting mixture was applied to the HiTrap SF column (1 ml., Pharmacia) equilibrated by 20 M of a sodium phosphate buffer (pH 6.0) containing 50 mM NaCl, followed by rinsing with the same buffer. The protein was then eluted with 0.1M sodium phosphate buffer (pH 6.0), containing guanidine hydrochloride acid. The elution was applied on the HPLC column for reverse phase Resource RPC (3 ml., Pharmacia) and the protein was eluted with acetonitrile from 25 to 55%. The fraction containing the MP52 of maturation was subjected to the analysis of the NH2 terminal amino acid sequence, by a one-pulse sequencer in gas-liquid phase (Applied Biosystems model 476). the result is shown in Table 1.

In the CHO-DUKX-B11 cells provided by Dr. Zettlmeissl of Behringwerke AG, expression of the human secretory mutant furin vector, pDfurpRC / CMV, which was described in Example 1 (1) was introduced by the method of co -precipitation of calcium phosphate DNA. The transforming cells were selected in the presence of G418, whereby a high expression of the human secretory mutant furin strain was established.
In a similar way to that described in example 1
(3) the co-precipitate of pDfurpRC / CMV and calcium phosphate was prepared, stored on CH0-DUKX-B11 cells in a dish of 10 ems. and kept at room temperature for 30 minutes. Cell layer was added, 8 ml. of a ribo- and deoxyribonucleotide medium containing MEM-ALPHA
(MEM a +) containing 10% FBS, followed by culture in a CO2 incubator for 4 to 6 hours. After treatment of the cells with 10% glycerol at room temperature for 3 minutes, they were again inoculated on a MEM-a + medium containing 10% FBS and 400 μg / ml. of G418, with which the transformant was selected. The production of the human secretory mutant furin cell line was detected by the enzymatic activity measurement method described above in Example 1 (6) to obtain a cell line having a furin activity of 500 to 1000 U / ml. 24 hours.
(2) Conversion of the precursor of the human MP52 dimer by maturation by means of the human secretory mutant furin
It was mixed with a serum free culture supernatant
(containing the MP52 dimers of maturation and the precursor) of the CHO cell production of the MC2 line of the human MP-52, a serum free from the culture supernatant (1000 U / ml) of the cell line expressed by the secretory mutant furin human in various proportions, followed by overnight incubation at 37 ° C. After the reaction, Western blot analysis as described above in Example 1 (5) was carried out under reducing conditions and the conversion of the MP52 precursor to maturation was detected. The result is shown in the photo of Fig. 4. In each of the steps from 1 to 5, a portion of 1 μl of the supernatant culture of the cell line expressed by the secretory mutant furin hunana was emptied. The final concentrations of the human secretory mutant furin was 0 U / ml. for stage 1, 50 U / ml for stage 2, 100 U / ml. for stage 3, 200 U / ml. for stage 4 and 400 U / ml. for stage 5, respectively. The band of the maturing monomer MP52 is indicated by the arrows A and B, whereas that of the maturing monomer MP52 is indicated by the arrow C. as illustrated in FIG. 4, the incorporation of the culture supernatant of the cell line expressing the human secretory mutant furin so as to give an active final concentration of at least 200 U / ml. turned into MP52 of maturing completely. As a result, the amount of the MP52 dimer of maturation was increased approximately 3 times.
