Definitions
- the present invention relates to a peptide for inhibiting osteoclast differentiation and its use.
- Bone homeostasis and the structural shape of the skeleton are maintained by organized activity between osteoclasts that absorb bone and osteoblasts that form bone.
- Osteoclasts which are multinuclear cells, are differentiated from hematopoietic stem cells [T. Miyamoto, 0. Ohneda, F. Arai, et al. , Blood 98 (2001) 2544-2554.] Differentiation into osteoclasts is regulated by RANK ligands secreted from osteoblasts and activated T lymphocytes [Y.Y. Kong, U. Feige, I. Sarosi, et al. , Nature 402 (1999) 304-309.
- RANKL receptor activator of nuclear factor kappa-B ligand binds to RANK, a receptor present in osteoclast precursors, and induces osteoclast differentiation when macrophage- colony stimulating factor (M-CSF) is present.
- M-CSF macrophage- colony stimulating factor
- RANKL activates signaling pathways that regulate osteoclast formation and bone resorption [J. Li, I. Sarosi, XQ Yan, et al. , Proc. Natl. Acad. Sci. USA 97 (2000) 1566-1571.].

(1999) Bone 25, 255-259].

- Experimental Example 5 Confirmation of signal inhibition of RANKL by synthetic peptide
- NF- ⁇ a representative signal of RANKL protein
- the effect of each peptide was confirmed by Western blotting using NF- ⁇ polyclonal antibody (Cat. No sc-372, Santa Cruz, USA).
- NF-icB activation and nuclear transfer were confirmed (FIGS. 7A and 7B).
- the phosphorylation of c-Jun and the phosphorylation of phosphorylated c-Jun were identified in the signal signaling of RANKL protein.
- the peptide synthesized in Synthesis Example 1 was treated with MC3T3-E1 cells at 10: or 50 tig / ml and induced differentiation for 2 days, followed by OCN (osteocalcin), OPN (osteoprotegerin), BSP (bone sialoprotein) and OPN (osteopontin). ) MRNA experiments of osteoblast differentiation markers were performed. 8 is used for PCR which is a differentiation marker of osteoblasts when the peptide of the present invention is treated.
- the target-specific primer sequences are as follows: 0CN forward primer sequence, 5′-gcgctctgtctctgacct-3 ′ and 0CN reverse primer, 5′-tttgtaggcggtct tcaagc-3 ′ (annealing temperature, 60 ° C.); OPG forward primer sequence, 5′-ctgcctgggaagaagatcag-3 ′ and 0PG reverse primer, 5′-t tgtgaagctgtgcaggaac-3 ′ (annealing degree, 60 ° C.); BSP forward primer sequence, 5′-aaagt gaaggaaagcgacga-3 ′ and BSP reverse primer, 5′-gttcct tctgcacctgct tc-3 ′ (annealing temperature, 60 ° C.); OPN forward primer sequence, 5′-GATGAATCTGACGAATCTCAC-3 ′ and 0PN
- the peptide of the present invention can promote osteoblast differentiation by increasing gene expression of osteoblast differentiation markers OCN, OPN, BSP and 0PN.
- Test Example 7 Confirmation of Signal Promoting Effect of Bone Differentiation by Synthetic Peptides
- MC3T3-E1 cells were dispensed into 2 x 10 5 cells in 6-well plates at 37 ° C for 24 hours. Incubated under 5% CO 2 conditions. After 24 hours, serum-free medium was exchanged for 24 hours to undergo starvat ion, and then the peptide was treated at 10 pg / ml or BMP2 was used as a positive control at 50 ng / ml. After treatment for minutes, the cells were washed with PBS and lysed in lysis buffer to obtain protein, followed by Western blotting.
