Definitions
- the present invention relates to a drug that exerts a preventive or therapeutic effect on diseases associated with destruction and degeneration of articular cartilage tissue such as osteoarthritis.
- Osteoarthritis is the collapse of the bone surface of the joints, resulting in the growth of new bones at the margins of the joints, deformation of the joints, loss of compatibility, and further spread to the inflammation of the synovium of the joints. It goes. These include secondary osteoarthritis, which has a primary disease that causes cartilage degeneration such as trauma or infection, and primary osteoarthritis, where the primary disease cannot be identified. Osteoarthritis is mainly caused by degeneration of the bones of the joints. The main causes are considered to be endogenous degeneration of articular cartilage and mechanical load applied to the joints. Many. There are two main pathologies of osteoarthritis.
- Cartilage in joint tissue is classified as permanent cartilage and is strictly distinguished from growth bone, which plays an important role in skeletal growth.
- growth chondrocytes present in epiphyseal plates, etc. proliferate and differentiate and then calcify and replace bone, thereby completing their physiological significance, whereas articular osteocytes usually do not undergo calcification .
- This is thought to be due to the fact that calcification is strongly suppressed in joint osteocytes environmentally, and that joint ⁇ bone retains elasticity by not calcifying, and the role of cushion against load and the role of joints This is because it guarantees easy mobility.
- Calcifying cartilage has high alkaline phosphatase activity (Robins on R., Bi
- An object of the present invention is to provide a preventive agent for a disease associated with destruction and degeneration of articular cartilage tissue such as osteoarthritis, and a therapeutic agent for a causative treatment and aggressive treatment. Disclosure of the invention
- the present invention relates to an agent for preventing or treating a disease associated with destruction and degeneration of articular cartilage tissue, comprising a PTH-related peptide (PTHrP) or a substance derived from PTHrP as an active ingredient.
- PTHrP PTH-related peptide
- the parathyroid hormone-related peptide (PTHrP) in the present invention includes natural PTHrP, PTHrP prepared by genetic engineering, and PTHrP chemically synthesized.
- Human PTH rp consisting of two amino acids, PTH rp of pigs and the like, and preferably human PTHrP.
- Ma The PTH rP-derived substance refers to a peptide obtained by substituting, deleting, or adding a partial amino acid of the PTH rP partial peptide, PTH rP itself, or a partial peptide thereof, to achieve the same activity.
- Means a peptide having Examples of the partial peptides of PTH r P include 1 to 34 PTH rP, 1 to 84 PTHrP, 3 to 141 PT Hrp, 7 to 141 PTHrp, 35 to 141 PTHrp, 85 to 141 PTHrp, and 107 to 141.
- Human 34 PTHrP Human 1-84PTHrP.
- 34PTHrP refers to a partial peptide of PTHrP consisting of 34 amino acids from the N-terminal to the 34th amino acid of PTHrP.
- the number of amino acid residues to be substituted, deleted or added is not particularly limited as long as the activity of the present invention is maintained.
- the disease associated with destruction and degeneration of articular cartilage tissue includes, for example, osteoarthritis and rheumatoid arthritis, and preferably osteoarthritis.
- type X collagen and alkaline phosphatase are known to be important expression substances in calcification of ⁇ bone or ⁇ subosseous bone. Suppressing the production of Izeze is effective in improving osteoarthritis. In addition, in osteoarthritis, a decrease in the synthesizing function of articular chondrocytes and the degradation of bone tissue due to matrix degradation are observed.Therefore, as a therapeutic agent for osteoarthritis, proteoglitin, a bone matrix, is used. Agents that promote synthesis rather than inhibit synthesis are preferred. Needless to say, a drug that does not have an unfavorable effect on osteocyte proliferation / differentiation, such as inhibiting chondrocyte proliferation, is preferred.
- the effects of PTH rP on proliferation, the expression of type X collagen, an important marker of cartilage tissue degeneration, the production of alkaline phosphatase, and subsequent calcification, and the expression of type II collagen, a cartilage matrix, are as follows: Culture of bone marrow cultured from young heron in a centrifuge tube (Ka to Y. eta 1., Proc. Natl. Acad. Sci. USA 85, 9552-9556, 1988, Iwamoto M. eta 1., Develop. Bio 1.136, 500-506, 1989), and a planar culture system of proliferating chondrocytes (Shi momura Y. et al., Calcif. Tissue). Re s
- the effect of PTH r P on the osteoclast matrix can be confirmed by using the synthesis of proteoglycan, which is the osteoma matrix, as an index.
- PTH rP acts during substrate synthesis of cultured osteocytes, and the uptake of 35 S-sulfate into the substrate can be confirmed as an index.
- FIG. 1 is an electrophoretogram showing the presence of the PTH rP receptor present in chondrocytes.
- FIG. 2 shows the activity of PTH r P to promote the synthesis of proteogliin, a major component of the bone matrix.
- FIG. 3 is a graph showing the effect of PTH r P on chondrocyte proliferation.
- FIG. 4 shows the dose response of PTH r P to chondrocyte proliferation.
- FIG. 5 is a graph showing the increase in ALP activity of osteoclasts over time and the inhibitory effect of PTH rP on it.
- FIG. 6 is a graph showing the dose-dependent ALP activity inhibitory effect of PTH rP.
- FIG. 7 is a diagram showing the calcification ability of chondrocytes over time and the inhibitory effect of PTH rP on it.
- FIG. 8 is a graph showing the dose-dependent calcification inhibitory effect of PTHrP.
- FIG. 9 is an electrophoresis photograph showing the effect of PTH rP on mRNA expression of type II and type X collagen.
- a drug expected to have localization and delayed action for example, encapsulation in a microcapsule or inclusion in a gel sheet. Shapes are also possible.
- a liquid preparation it is preferable to add an appropriate protein or an appropriate anti-adhesion agent.
- the method of administering the drug of the present invention includes, for example, subcutaneous administration, oral administration, transdermal administration, rectal administration, topical administration, and the like, with local administration being preferred. In particular, local injection into a joint cavity or a lesion by injection is preferred.
- the dosage of PTH r P of the present invention, the adaptive diseases varies depending on such conditions, example, an organization level 10 20 10 5 M, preferably from 10 15 10 7 M.
- the PTH rP used in the examples was human 34 PTH r P purchased from Beptide Institute.
- the proliferating osteocytes were transferred to the costal cartilage bone of a 4-week old heron Sep. 19, 1979, 187-187, 1975) by Shimomura et al. (Shi momu ra Y. eta 1., C a 1 cif. T issue Res. 19).
- Culture of osteoclasts in the centrifugal canal was performed by the method of Iwamoto et al. (Iwamo to M. eta 1., Dev. Biol. 136, 500—507, 1989) and the method of Kato et al. etal., Endocrinology 127, 114-118, 1990).
- the isolated chondrocytes were suspended in Eagle's minimum essential medium (MEM) containing 10% fetal bovine serum (FBS) and 50 g / m1 ascorbic acid at a concentration of 8 ⁇ 104 cells / m1. Each 1 ml was seeded into a 15 ml plastic centrifuge tube (Koingen). After centrifugation (1,500 rpm) for 5 minutes, the cells were cultured in a carbon dioxide incubator set at 37 ° C. The medium was replaced every two days after the sixth day of culture. Confirmation of the PTH rP receptor in chondrocytes was performed by SDS gel electrophoresis.
- MEM Eagle's minimum essential medium
- FBS fetal bovine serum
- chondrocytes on the 14th day of culture were homogenized and then incubated with 125 I-labeled PTHrP for 5 hours.
- the PTH rP bound to the receptor was cross-linked with DSS, solubilized with SDS buffer, and electrophoresed by SDS gel electrophoresis. After electrophoresis, autoradiography was performed by a conventional method.
- a sample in which an excess amount of PTH rP was added to inhibit the binding of 125 I-PTH rP to the receptor was electrophoresed by SDS gel electrophoresis in the same procedure and subjected to autoradiography.
- Figure 1 shows the results.
- the binding between 125 I-PTH rP and the receptor migrated around a molecular weight of about 76 kDa (Fig. 1, left), and the binding was completely blocked by the addition of excess PTH rP (Fig. 1 ⁇ right) This suggests that a PTH rP receptor is present in chondrocytes, and that PTH rP can exert the following various effects via the receptor.
- the proliferating chondrocytes were isolated in the same manner as in Example 1 by the method of Shimomura et al. (Shi momu ra Y. eta 1., Ca 1 cif. s. 19, 179-187, 1975).
- the isolated chondrocytes contained 10% fetal calf serum and 50 ⁇ g / m1 ascorbic acid.
- the suspension was suspended in Mu Eagle's minimum essential medium (MEM), and 5,000 cells were seeded on 96-well culture plates. After the cells became confluent, PTH rP was added, and after 1 hour, 1 Ci of 35 S-sulfuric acid was added per well and cultured for 17 hours.
- MEM Mu Eagle's minimum essential medium
- the amount of bone matrix produced in the culture supernatant was determined by the method of Kato et al. (Kato OY. Eta 1., Endo cri no loy, 122. 1991-1997, 1988). That is, the amount of 35 S-sulfuric acid incorporated into proteoglycan was measured.
- FIG. 2 The result is shown in figure 2.
- the figure shows the concentration-response curve with 10- 6 M concentration of PTH r P from 10- 1 ().
- Bone cells were cultured in a centrifuge tube as in Example 1. Were cultured PTHr P 10- 7 by adding 28 days of culture 8 ⁇ . After the culture, the cells were appropriately solubilized and the amount of DNA over time was measured. It was also measured the amount of DNA culture day 21 with the addition of PTH r P from 10- 1 () to 10 7 M.
- Fig. 3 shows changes in the amount of DNA in osteocytes over time
- Fig. 4 shows the dose response of PTH rP to the amount of DNA.
- the amount of DNA in the control group increased over time, indicating that osteoclasts had proliferated well in the centrifuge tube.
- the addition of PTHrP had no effect on the amount of DNA in osteoblasts. This indicates that PTHrP is not a drug that has any adverse effect on bone cell proliferation.
- the chondrocytes were cultured in a centrifuge tube as in Example 1.
- the PTHr p on day culture 8 ⁇ was added to a 10- 7 M, were cultured to Me up to 28 days.
- a group from which PTH rP was removed was set as the culture 21 and compared with the PTH rP added group.
- PTH r P from 10- 1G to 10- 7 M was added to confirm the dose-response for alkaline phosphatase activity (AL P activity).
- ALP activity dose-response for alkaline phosphatase activity
- FIG. 5 shows the effect of PTH rP on ALP activity over time
- FIG. 6 shows the dose response of PTH rP to ALP activity on day 21 after addition of PTH rP.
- the addition of PTH rP suppressed the ALP activity of osteoclasts, and it was clarified that the effect continued during PTH rP action (Fig. 5 ⁇ PTH rP added group).
- the effect was reversible, and ALP activity was restored to the level of the control group by removing PTH rP from the culture medium at the time of culture 21 (Fig. 5: PTH rP removal group).
- This effect was concentration-dependent, inhibited by beginning to the A LP activity at a concentration of at least 10- 9 M, inhibited almost completely AL P activity at 10- 8 M (FIG. 6).
- PTH r P also suppressed subsequent calcification. That, 10- 7 PTH r P of M inhibits 45 C a uptake into ⁇ cells ( Figure 7 ⁇ PTH r P added group), the effect is canceled immediately by removing the PTH r P (Fig. 7 ⁇ PTH rP removal group). Calcification suppressing action of PTH r P is dose-dependent and was completely inhibited calcification of chondrocytes at a concentration of at least 10- 8 M (FIG. 8). These results indicate that PTH rP is effective as a therapeutic agent for osteoarthritis.
- Isolation of proliferating chondrocytes was carried out in the same manner as in Example 1 by the method of Shimomura et al. (Shi momu ra Y. eta 1., Ca 1 cif. e s. 19, 179–187, 1975).
- the isolated chondrocytes were suspended in Eagle's minimum essential medium (MEM) containing 10% fetal calf serum and 50 ag / l ascorbic acid and placed in a 3.5 cm Petri dish coated with type I collagen. Individually sown. After 30 days of culture, the last 6 The PTH r P of 1 O-8 and 10- 7 M was allowed to act on the day.
- MEM Eagle's minimum essential medium
- RNA was prepared from the cultured cells by the CsTFA method (Small and Sasse, Anal. Biochem., 203, 352-356, 1992), separated by electrophoresis, and then applied to a membrane. Transferred. The transferred membrane was hybridized with a type X collagen and type II collagen 32 P level cDNA probe.
- Fig. 9 shows the results.
- the left figure shows the expression of type II collagen mRNA
- the right figure shows the expression of type X collagen mRNA.
- PTH r P 10 and 10- 7 M whereas has failed adversely any effect on expression of type II collagen was strongly inhibited the expression of type X collagen mRNA in a dose-dependent manner.
- PTHrP specifically suppresses the expression of type X collagen, which is strongly involved in calcification.In other words, although PTHrP strongly suppresses bone calcification, it inhibits the production of type II collagen, a matrix component. It means no adverse effects.
- the drug containing PTH rP of the present invention as an active ingredient is useful for the prevention of diseases associated with rupture and degeneration of articular cartilage tissue such as osteoarthritis, and for the therapeutic and aggressive treatment.
