Bone metabolism is composed of osteoblasts responsible for bone formation and osteoclasts responsible for bone resorption, and the function of these cells is balanced to maintain homeostasis. However, when osteoblast activity decreases or osteoclast activity increases, bone density decreases and osteoporosis may be induced. Factors causing osteoporosis include menopause in women, hyperthyroidism, diabetes, stress, smoking and lack of exercise, physical aging and the use of glucocorticoid drugs (Kumamoto H, Ooya K. ExpreASion of parathyroid hormone-related protein ( PTHrP), osteoclast differentiation factor (ODF) / receptor activator of nuclear factor-kappaB ligand (RANKL) and osteoclastogenesis inhibitory factor (OCIF) / osteoprotegerin (OPG) in ameloblastomas.J Oral Pathol Med. 2004, 33 (1): 46- 52; Reddy SV.Regulatory mechanisms operative in osteoclasts.Crit Rev Eukaryot Gene Expr. 2004, 14 (4): 255-70; Pang M, Martinez AF, Fernandez I, Balkan W, Troen BR.AP-1 stimulates the cathepsin K promoter in RAW 264.7 cells.Gen., 2007, 403 (1-2): 151-8).

Osteoclasts are differentiated by various differentiation-causing factors in macrophage progenitor cells (Boyce BF, Yamashita T, Yao Z, Zhang Q, Li F, Xing L. Roles for NF-kappaB and c-Fos in osteoclasts. J Bone Miner Metab. 2005, 23 Suppl .: 11-5; Khosla S. Minireview: the OPG / RANKL / RANK system.Endocrinology. 2001, 142 (12): 5050-5). In particular, RANKL (receptor activator of nuclear factor kappa B ligand) secreted from osteoblasts binds to osteoclast precursor cells and RANK (receptor activator of nuclear factor kappa B) present on the surface of osteoclasts. Induce differentiation and activation (Han SY, Lee NK, Kim KH, Jang IW, Yim M, Kim JH, Lee WJ, Lee SY. Transcriptional induction of cyclooxygenase-2 in osteoclast precursors is involved in RANKL-induced osteoclastogenesis.Blood. 2005; 106 (4): 1240-5). Differentiated osteoclasts catarsin TRAP (tartarate resistant acid phosphatase) through activation of NF-B, c-Fos, c-jun, AP-1, NFATc1, MAPK, ERK, JNK, p38 activation process, Src, Akt activation Promote osteoclast specific protein expression such as K, calcitonin receptor (Yamashita M, Otsuka F, Mukai T, Yamanaka R, Otani H, Matsumoto Y, Nakamura E, Takano M, Sada KE, Makino H.

Example 1 Preparation of Millitaris Cordyceps Sinensis Extract

Militaris Cordyceps sinensis was added to 30% ethanol 10 times the weight, and then extracted with boiling water for 4 hours. The extract was concentrated and then freeze-dried and used as a sample of the following experimental example.

Experimental Example 1. Cell Culture and Drug Treatment

The RAW 264.7 cells used in the experiment were cultured in a CO2 cell incubator using DMEM (Dulbecco's modified eagle medium) / 10% fetal bovine serum (FBS) / PC-SM medium, and the number of cells was 96 well plate at 5x10 3 cells / well. And cultured using. After culturing for 24 hours, the culture medium was discarded, and the cells were cultured by exchanging with a-MEM to which 10% FBS, 50 ng / ml RANKL, and 1 ng / ml TGFb were added. Different concentrations of AS were added to the culture. It was incubated for 6 days while changing to the same medium every two days. The experimental group was administered with (1) RANKL-treated control group (N) (2) RANKL-induced control group (C), (2) RANKL-induced group + 1 / of Millitaris Cordyceps Sinensis extract of Example 1 (CM 0.1) , (3) RANKL induction group + 5 / to the group to which the milliliris cordyceps extract of Example 1 was administered (CM1).

Experimental Example 2. Measurement of osteoclast generation capacity

After inducing RAW 264.7 cells to osteoclasts with RANKL (receptor activator for nuclear factor B ligand), TRAP-positive multinucleated cells (TRAP (+) MNCs) were identified by staining TRAP, a marker for expression of mature osteoclasts. . Differentiated cells were washed twice with PBS, fixed with 3.7% formaldehyde-citrate-acetone solution for 10 minutes and washed twice with distilled water. Treat the cells prepared by mixing 2% TRAP fast garnet GBC base solution with NaNO3 solution in the same ratio and a solution containing 5% naphtha AS-BI phosphoric acid, 4% acetic acid and 2% tartaric acid. It was left for more than a minute. Observed by light microscopy, TRAP-positive multinucleated cells (TRAP (+) MNCs) having three or more nuclei were counted as markers for the generation of osteoclasts (Choi HJ, Park YR, Nepal M, Choi BY, Cho NP, Choi).

Experimental Example 3. Effect on Gene Expression

Experiments were performed as follows to determine the effect on gene expression of factors related to osteoclast differentiation and proliferation of the Millitaris cordyceps sinensis extract of Example 1, such as TRAP, JNK, AKT1.

3-1. gun RNA  detach

Total RNA was isolated from TRAP (+) multinuclear cells differentiated into osteoclasts by treatment with 1 ml Trizol solution (Invitrogen, USA). 100 phenol and 100 chloroform: isoamyl alcohol (24: 1) are added to the isolated RNA, and the mixture is mixed well and centrifuged twice to separate the supernatant. RNA is precipitated using 0.5 ml isopropyl alcohol, washed with 70% ethanol and dried naturally. RNA was thawed in RNAase free water (RNA) free water (Promega, USA), followed by the addition of ALNAISE-free DNase (RNase-free DNase, Promega, USA) and stored at -70 ° C.

3-2. cDNA  Produce

Oligo dT 1 was added to the total RNA solution (containing 13 ug RNA) of each of the control and experimental groups isolated in Experimental Example 3-1, mixed carefully, and then incubated at 70 ° C. for 5 minutes. Leave primers at room temperature for about 10 minutes to release the primers, then add cyscript buffer, 0.1 M DTT, dUTP nucleotides, dUTP seeded-labeled nucleotides, Cyscript reverse transcriptase, and then add Mix carefully. Thereafter, the cells were incubated at 42 ° C. for 90 minutes and then left on ice. 2.5 M sodium hydroxide was added thereto, followed by incubation at 37 ° C. for 15 minutes, and neutralized by adding 2 M HEPES buffer to prepare cDNA.

3-3. Real time RT - PCR

First, 5 ug of RNA, 50 ng / random hexamer (random hexamer) 3, 10 mM dNTP 1, were added to the test tube, and DEPC-H 2 O was added to make an RNA / primer mixture of 10. The experimental sample was incubated at 65 ° C. for 5 minutes and then left on ice for at least 1 minute. The reaction mixture was prepared by mixing 10-fold RT buffer 2, 25 mM magnesium chloride 4, 0.1 M DTT 2, RNAase (Promega, USA) 1. The reaction mixture was added to the RNA / primer mixture, left to stand at room temperature for 2 minutes, then SuperScript II RT (Promega, USA) 1 (50 units) was added and incubated at 25 ° C. for 10 minutes. Incubated at 42 o C for 50 min, then inactivated by heating at 70 o C for 15 min and cooled on ice. RNase (Promega, USA) 1 was added and incubated again at 37 o C for 20 min, then stored at -20 o C until use. Into each optical tube (optical tube, Gibco, USA) add 2x Cyber Green Mix (SYBR Green Mix, Takara, Japan) 12.5, cDNA 0.2, 5 pmol / primer pair mix 1, 11.3 H 2 O, 50 o Amplification with C 2 min 1 cycle, 95 ° C 10 min 1 cycle, 95 ° C 15 sec, 60 ° C 30 sec, 72 ° C 30 sec 40 cycles, 72 ° C 10 min 1 cycle. After completing the PCR, the tube was taken out, and PCR specificity was measured on a 3% agarose gel using 5 ul of the reaction solution. Real time PCR results were analyzed using SDS 7000 software.

Treatment of receptor activator for nuclear factor B ligand (RANKL) in RAW264.7 cells increased the expression of TRAP (+) multinucleated cells (MNCs) to promote osteoclast differentiation, and in this example, the extract of Militaris cordyceps was 0.1 ug /. ml, 1 ug / ml, it was shown to inhibit the receptor activator for nuclear factor B ligand (RANKL) -induced osteoclast differentiation at concentrations (FIG. 1) .TAP (tartarate resistance Acid Phosphatase), JNK, and AKT1 were expressed during RANKL treatment. It was confirmed that the Millitaris cordyceps sinensis extract significantly inhibited the gene expression increased at 0.1 ug / ml, 1 ug / ml (see FIGS. 2, 3 and 4). Therefore, Militaris cordyceps sinensis extract was found to have an excellent effect in inhibiting TRAP, JNK, AKT1 gene expression.

Statistical treatments were compared individually using Student's t-test and determined that there was a significant difference when the p-value was less than 0.05.
