Cancer is one of the incurable diseases. In Korea, about 100,000 people are diagnosed with cancer annually, and about 60,000 people die from cancer. Cancer inducers vary in genetic and environmental factors, and there are difficulties in the development of therapeutic agents due to the different effects of therapeutic agents depending on the site of occurrence. In addition, most of the substances currently used as medicines for treatment have significant toxicity, do not selectively remove cancer cells, and cause many side effects.

Among cancers, white blood cells, white blood cells, red blood cells, platelets, and other white blood cells among blood cells, called bone marrow, are called leukemia. Abnormal white blood cells (leukemia cells) are overproduced and the production of normal white blood cells, red blood cells and platelets is suppressed. When the normal white blood cell count is decreased, immunity deterioration may cause septicemia due to bacterial infection, , Dyspnea, etc., and platelet reduction causes hemorrhagic tendency. In addition, hypertrophic leukemia cells may cause high fever, fatigue, bone pain, diarrhea, decreased consciousness, dyspnea, etc. Leukemia cells may not be able to stop growth, restrict proliferation, Do.

Although the combination of cytarabine and anthracycline is commonly used in the treatment of leukemia, these drugs have limited treatment capacity and recurrence of the disease is frequent. Therefore, there is a strong demand for the development of new therapeutic agents that can overcome drug resistance and utilize apoptosis potency.

Ochiza (S chisandrae chinensis ) is distributed over 200-1,600m above sea level and is a deciduous deciduous broad-leaved tree that grows widely in Mt. Jiri, Mt. The leaves are 6 ~ 9m long, 7 ~ 10㎝ long, 3 ~ 5㎝ wide, with hairs on the back vein, small teeth on the edge, and wide oval shape. The flower is slightly reddish yellowish white with a diameter of about 1.5㎝. It blooms one by one on the axil of the short branch of newly emerged 3-5. The fruit is strong in sour taste and ripen in red color from August to September, and its length is 0.6 ~ 1.2㎝, and several dogs are hanging down with grape clusters. It is used for ornamental purposes, and the fruit is used for medicinal purposes.

As for the specific prior art, Prior Art 1 (KR 10-2010-0072390 A, published on July 01, 2010) discloses a composition for raw rice wine containing an extract of Omija. However, this is based on the taste and aroma of Omija, and since it is a natural fruit extract, the beneficial ingredients of Omija are said to promote health, and it can be said that research on specific effects or characteristics other than taste has not been made.

Therefore, the prior art of the prior art is not enough to study the new effects of Omija besides the food composition based on the unique flavor and texture of Omija. Therefore, the present invention has been completed on the basis of the characteristics of the cancer effect of Omiza while studying the new effect features of Omiza.

The cells were then flow cytometry analyzed from a DNA bar graph to determine cell rates at different stages of the cell cycle. The cells in the sub-G1 DNA stage were considered dead cells. To count the number of cells in different stages of apoptosis in each sample, the cells were stained with 5 μl of Annexin V-fluorescein isothiocyanate (R & D Systems, USA) and 1 μl of PI Respectively. After 15 min of incubation at room temperature, cell death was quantified by flow cytometry using the ratio of Annexin V-positive and PI-negative cells (Annexin V + / PI - cells).

[Experimental Example 5: Protein extraction and Western blot analysis]

The harvested cells were treated with lysis buffer (20 mM sucrose, 1 mM EDTA, 20 μM Tris-Cl, pH 7.2, 1 mM dithiothreitol, 10 mM KCl, 1.5 mM MgCl 2 , 5 μg / ml pepstatin A, ml leupeptin, and 2 μg / ml aprotinin) for 30 min at 4 ° C. In parallel with the experiment, the nuclear / cytosol and mitochondrial / cytosolic fractions were separated according to the user manual using a commercial fractionation kit (Biovision, Milpitas, Calif., USA) The same amount of protein was separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and the nitrocellulose membrane (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) The membrane was then incubated with PBST buffer (containing 0.05% Triton X-100) containing 5% non-fat milk to block non-specific binding. PBS for 1 hour and probed with complementary antibodies to specific proteins for 2 hours at 37 ° C or overnight at 4 ° C. Washed with PBST buffer and incubated with appropriate peroxidase-conjugated secondary antibody for 1 hour. After the final wash, the specific protein was incubated with a chemiluminescence kit (Amersham Corp.). Primary antibodies were obtained from Santa Cruz Biotechnology (Santa Cruz, USA), Chemicon (Temecula, USA), and Sigma-Aldrich Peroxidase-labeled donkey anti-rabbit and sheep anti-mouse immunoglobulin were purchased from Amersham Corp. (Piscataway, USA) and used .

[Experimental Example 6: Caspase activity assay]

Measurement of caspase activity was performed using a colorimetric assay kit (R & D Systems) based on the ability of the active caspase to cleave the chromophore from the enzyme-substrate. Omiza extract-treated and untreated cells were dissolved in a lysis buffer and the lysate was mixed with a reaction buffer and incubated with a caspase-specific substrate (Caspase-3 is Asp-Glu-Val-Asp, caspase-8 is Ile-Glu-Thr-Asp, caspase-9 is Leu -Glu-His-Asp) at 37 < 0 > C for 3 hours. The pNA release was measured at 405 nm using an ELISA reader. The results are shown in Fig.

[Experimental Example 7: Detection of MMP (占 m)]

Dyes having cell permeability, cationic and lipophilic properties are internalized by mitochondrial respiration, accumulate, and reflect the change of MMP in living cells, so that the mitochondrial potential sensor, 5,5 ', 6,6'-tetrachloro -1,1 ', 3,3'-tetraethyl-imidacarbocyanine iodide (5,5', 6,6'-tetrachloro-1,1 ', 3,3'- 1, Sigma-Aldrich) was used to measure the mitochondrial transmembrane electrochemical gradient. Specifically, the collected cells were cultured for 20 minutes in a dark condition with 10 μM of JC-1 at 37 ° C. After the cells were cultured, the cells were washed with PBS to remove unbound dye, and then analyzed by flow cytometry using JC -1 was measured. The amount of JC-1 containing about 10,000 cells per sample was measured using a flow cytometer at 488 nm and 575 nm.

[Experimental example 8] Measurement of intracellular ROS [

2,7-Dichlorodihydrofluorescein diacetate (DCFH-DA, Molecular Probes, USA) was used to test the effect of the extract of Orimida on the production of active oxygen. Cells from each treatment were harvested, washed twice with PBS, resuspended in 10 μM DCFH-DA, and maintained at 37 ° C for 30 min. The active oxygen production of the cells was immediately observed by flow cytometry using Cell-Quest pro software.

In order to confirm the association of high concentration of active oxygen in the extract of Omija-induced cell death, the cells were treated with N-acetylcysteine (NAC, Calbiochem), which is conventionally used as an antioxidant, for 2 hours before treatment with Omiza extract ) Were used for pre-culture.

Test Example 1. Identification of Anti-proliferative Activity and Apoptosis-inducing Effect of Omiza Extract in U937 Cells [

To examine the effect of Omiza extract on U937 cell proliferation, 1 × 10 5 cells / ml were each seeded and cultured for 24 hours. The cells were treated with 60 μg / ml of Omija extract for 0, 3, 6, 12, 18, and 24 hours, respectively, and cell activity was confirmed by MTT assay. The results are shown in FIG.

To confirm whether the inhibitory effect of Omiza extract on cells was related to induction of apoptosis, DNA was stained with DAPI and confirmed by fluorescence microscopy. The chromatin concentration of the nucleus, which is characteristic of apoptotic cells, and the number of sub-G1 stage and the number of Annexin V-positive cells were measured, and the results are shown in FIG.

As shown in Fig. 1, in U937 cells, Omija extract caused a significant decrease in cell activity in a time-dependent manner. As shown in FIG. 2 A, it was found that the number of chromatin condensation and cell killing was significantly increased in the cells treated with Omija extract in a time-dependent manner, while it was confirmed that these characteristics were not observed in the control cells. In addition, as shown in FIG. 2B, cell cycle analysis by flow cytometry showed that the accumulation of sub-G1 phase cells was increased in a time-dependent manner after treatment with Omija extract. As shown in Fig. 2C, the Annexin-V and PI double-staining revealed increased cell death rates in cells treated with Omija extract (Fig. 2C).

Therefore, it was confirmed that when treated with the extract of Omija, the activity of the cells was lowered and the cell death was increased, and that the Omija extract was effective in inhibiting cell proliferation and inducing apoptosis.

[Test Example 2: Examination of the activity of caspase and the degradation effect of PARP in U937 cells of Omiza extract]

(-3, -8 and -9) and poly (ADP-ribose) -polymerase, to confirm the relevance of caspase activity in Omiza extract-induced cell death. PARP) was measured, and the results are shown in Fig. 3A.

In order to demonstrate that caspase activity is associated with Omija extract-induced apoptosis in U937 cells, the cells were pretreated with 50 [mu] M pan-caspase inhibitor z-VAD-fmk, / ml for 24 hours, and the results of the observation are shown in Fig.

As shown in Figure 3A, western blot analysis showed that the expression levels of pro-caspase-8, -9, the initiator caspases of extrinsic and intrinsic apoptotic pathways, Were down-regulated, whereas their active forms were up-regulated in a time-dependent manner. As shown in FIG. 3B, the activity of caspase-3, -8 and -9 was remarkably increased by 4.3-, 2.7-, and 3.1-fold, respectively, when Schizo extract (SSeo) was treated at 60? / Ml for 24 hours (Fig. 3B). Treatment of U937 cells with Omiza extract resulted in a time-dependent increase in the effector caspase, caspase-3, segmented fragment, and the caspase-3 substrate to produce an 85 kDa segmented fragment Leading to a gradual protein hydrolysis segment of the known PARP (116 kDa). Accordingly, the activity of this caspase was measured through quantitative detection of colorimetric tetrapeptide substrates, and as a result, it was found that the Omija extract stimulates caspase-3, -8 and -9 activity in a time-dependent manner Respectively.

In addition, as shown in Figs. 3C and 3D, it was confirmed that pretreatment with z-VED-fmk remarkably prevented accumulation of sub-G1 cells and apoptosis. This means that apoptosis induced by Omiza extract in U937 cells will be regulated through a caspase-dependent extrinsic and intrinsic pathways (Fig. 3C and D).

In addition, the SSeo treatment reduced down-regulated proteins of the apoptosis protein (IAP) family, such as XIAP, cIAP-1, cIAP-2 and survivin, which bind to caspases and cause inactivation (Fig. 4), which means that the activity of Omija extract-induced caspase is associated with a decrease in IAP family protein in U937 cells.

Therefore, it was confirmed that the treatment with Omiza extract increased cell death, and that the effect of Omiza extract on cell proliferation inhibition and death induction was related to caspase activity.

[Test Example 3: Effect of Omiza extract on recovery of mitochondrial apoptosis pathway in U937 cells]

In order to confirm whether or not the Omiza extract activates the mitochondrial apoptotic pathway, the MMP value was analyzed by staining with JC-1, and the result is shown in FIG.

As shown in FIG. 5A, treatment of U937 cells with Omiza extract resulted in a time-dependent reduction in MMP levels, suggesting that depolarization of mitochondria occurs by the extract of Omija. Furthermore, in order to characterize the mitochondria - regulated apoptotic effect of the extract of Omija in U937 cells, the dislocation of Bax and the release of cytochrome c were analyzed using cytoplasmic and mitochondrial classifications. As shown in Figure 5B, the immunoblot results confirmed that the Schizo extract treatment (SSeo) induces a time-dependent increase in the release of cytochrome c from the mitochondria to the cytoplasm. In particular, the total levels of pro-apoptotic Bax and anti-apoptotic Bcl-2 protein remained unchanged despite treatment with Omija extract (Fig. 5C); However, increasing the concentration of Omiza extract significantly increased mitochondrial levels, whereas treatment with Omine extract (SSeo) reduced the cellular level of Bax (Fig. 5B). These results are generated by inducing translocation of Bax to the mitochondria, and the loss of MMP and the release of cytokine c to the cytoplasm of Omija extract-induced apoptosis are responsible for the apoptosis of caspase-9 and -3 Resulting in activation.

From the above results, it was experimentally confirmed that cell death was caused by caspase activity when treated with an extract of Omija.

Test Example 4. Confirmation of induction effect of cleavage of Bid and expression of DR-related proteins in U937 cells of Omiza extract [

In order to confirm the signaling mechanism of cell death by treatment with Omija extract, the effect of Omiza extract on the level of DR-related protein and Bid expression was further observed.

 As a result, levels of DR ligands such as tumor necrosis factor-associated apoptosis inducing ligands and Fas ligands were relatively unchanged for treatment with Omija extract;

However, as shown in FIG. 4, DR4, DR5, and Fas levels increased significantly in a time-dependent manner (FIG. 4). Western blot analysis then showed a gradual downward regulation of total Bid protein and the accumulation of tBid (Figure 5C) resulting from cleavage by caspase-8 produced in the cells.

These results indicate that the cytotoxic effect of the Schizandra chinensis extract could be controlled through DR-regulated apoptosis and that it would thus emphasize crosstalk between internal and external apoptotic pathways , And the pathway of apoptosis mechanism to the extract of Omija was experimentally confirmed.

Test Example 5. Confirmation of nuclear potential enhancement effect of EndoG and AIF in U937 cells [

In addition to cytochrome c , the release of other mitochondrial proteins such as endonuclease G (EndoG) and AIF is a major event that occurs during apoptosis. These proteins release into the cytoplasm and into the nucleus when the MMP is lost, leading to apoptosis through a caspase-independent mechanism.

In this regard, western blotting was performed to compare levels of endogenous G (EndoG) and AIF using mitochondria, cytoplasm and nuclear fragments, and the results are shown in FIG.

Western blot analysis revealed that treatment of Omiza extract induced the dislocation of EndoG to the nucleus (Fig. 6B), although control cells showed a significant lack of nuclear expression of EndoG. Similarly, the level of AIF in U937 cells exposed to Omiza extract was further enhanced in the cytoplasm and nuclear fraction and decreased in the mitochondrial fraction, indicating the promotion of migration to the nucleus (Fig. 6A).

Taken together, these results demonstrate that both the caspase-dependent and non-caspase-induced apoptosis of U937 cells are induced by Omija extract.

Test Example 6. Confirmation of Promoting Effect of ROS Generation on Extract of Omiza in U937 Cells [

To determine if Omija extract-induced cell death is regulated by oxidative stress; The level of intracellular reactive oxygen (ROS) was measured using a ROS-detecting fluorescent dye DCFH-DA, and the results are shown in FIG.

As shown in Fig. 7A, the flow cytometry analysis showed that the Schizandra chinensis extract produced active oxygen within 15 minutes, and the level continued to increase until 30 minutes. In addition, pretreatment with 10 mM NAC (a commonly used ROS abolisher) completely blocked ROS production in U937 cells treated with Omija extract as well as in control cells.

U937 cells were pretreated with NAC and then treated with Omija extract to determine whether the oxidative burst induced by Omiza extract was the most important factor for pro-apoptotic activity.

As shown in FIGS. 7B and 7C, the number of Omija extract-induced Annexin-V + cells was completely removed by pretreatment with NAC (FIG. 7B). In addition, treatment of the cells with NAC significantly reduced the loss of Omija extract-induced MMP (Fig. 7C).

These results confirmed that the production of reactive oxygen species (UO) in U937 cells is an important factor in the pathogenesis of Omiza extract-regulated mitochondria-dependent cell death signaling pathways.

In the case of Example 1, there was a disadvantage in that the taste of Omija remained and the flavor of the mixture did not match. In Example 5, there was a disadvantage that the unique flavor of Omija was reduced and it was difficult to feel Omija flavor.

2. Caspase-8 activity of the mixed extract
