Mesenchymal stem cells are known to be present in adult as well as embryonic cells, which can be differentiated into various tissue cells. Recently, studies on such stem cells have been actively conducted. These mesenchymal stem cells can be converted into epithelial cells by a unique process called epithelial-mesenchymal transition (EMT) / mesenchymal-epithelial transition (MET) It is known that EMT is not only a process that is essential for the formation of various tissues or organs of a fetus by the differentiation process at the development stage but also a process that is essentially performed in processes such as wound healing and tissue regeneration in the adult have. There are three known effects of EMT in vivo. First, it is involved in embryo implantation, embryogenesis, embryogenesis, neurotransmission, heart, and skeletal development in normal fetal development. In general, it occurs in the stage of development of the embryo. Second, it induces fibrosis of tissues in the renal tubules, lens epithelial cells, hepatocytes, dendritic cells, myocardial cells and the like. Third, it plays an important role in the metastasis of cancer, the generation of cancer stem cells, and the induction of tolerance to anticancer drugs, and it occurs in cancer-related diseases such as cancer metastasis. Particularly, since the above-mentioned third type is found in cancer-related diseases, it is expected that when the EMT process is inhibited at the onset of the cancer disease, the onset of the disease can be prevented or treated early, It is progressing. For example, WO2009-067429 discloses a method of treating cancer by blocking EMT using a monoclonal antibody that binds to? 2 and blocks the binding of? 2 to Notch1, Korean Patent Publication No. 2013-0015669 discloses a method of treating cancer Discloses a method for inhibiting proliferation, differentiation, or metastasis of cancer stem cells by inhibiting EMT using 2-Deoxy-D-glucose, Korean Patent Laid-Open Publication No. 2014-0062724 Korean Patent Laid-Open Publication No. 2014-0089234 discloses a method for suppressing EMT by inhibiting EMT using fibulin-3 protein, and Korean Patent Laid-Open Publication No. 2014-0089234 discloses a method for inhibiting the expression of a CD44 promoter and a luciferase gene operably linked thereto Discloses a method of screening a drug for EMT inhibition using a recombinant vector for EMT monitoring. However, most of the methods thus far developed are directed to a method for preventing or treating cancer metastasis, proliferation, etc. by inhibiting EMT by using a specific compound, and it is disadvantageous in that it is accompanied by mild or serious side effects similar to other anticancer drugs The development of safer EMT inhibitors is required.

On the other hand, red ginseng has been used as a medicinal product derived from natural products prepared by drying ginseng containing various pharmacologically active ingredients such as saponin, and has been used for treatment of various symptoms from whales in Korea and other Far East Asian countries. Recently, research on various ginsenosides contained in ginseng or red ginseng has been conducted. As a result, ginsenosides contained in ginseng or red ginseng have been identified as glycosides. In particular, in the case of red ginseng, Rg3 Of ginsenosides were found to be significantly higher than that of ginseng.

FIG. 2A is a graph showing the results of analysis of the effect of red ginseng extract on mRNA level of snail under the condition that DFO was treated with a colorectal cancer cell line (HCT116). FIG. 2B is a graph showing the effect of DFO treatment on colorectal cancer cell line FIG. 2C is a graph showing the effect of red ginseng extract on the mRNA level of snails. FIG. 2C is a graph showing the effect of red ginseng extract on slug mRNA levels in DFO-treated colon cancer cell line (HCT116) And FIG. 2d is a graph showing the results of analysis of the effect of red ginseng extract on the mRNA level of Slug under the condition of treating DFO in the colon cancer cell line (HT29). As shown in FIGS. 2A to 2D, when the DFO was treated alone, mRNA levels of Snail and Slug were rapidly increased. However, when the red ginseng extract was treated, the mRNA levels of Snail and Slug were dependent on the treatment concentration of red ginseng extract .

Example  2-2: Under hypoxic conditions  Red ginseng extract Cadherin (E- caherin ) And visentin ( Vimentin  Effect on expression level

Colon cancer cell lines (HCT116, DLD1 or HT29) were inoculated into culture dishes at 1 × 10 6 cells, treated with 50 μM DFO and various concentrations of red ginseng (0, 0.5, 1 or 2 mg / (HCT116), 6 days (DLD1) or 3 days (HT29). After completion of the culture, a western blot analysis using an anti-cadherin antibody or an anti-Vimentin antibody was performed on each of the cultured cell lysates (Figs. 3A to 3C). At this time, as a control group, cells cultured without DFO treatment were used and β-actin was used as an internal control group.

FIG. 3 (a) is a Western blot analysis photograph showing the effect of red ginseng extract on the expression level of camphorin on the condition that DFO was treated with a colorectal cancer cell line (HCT116) FIG. 3c is a photograph of Western blot analysis showing the effect of red ginseng extract on the expression level of cadherin. FIG. 3c is a graph showing the effect of red ginseng extract on the expression level of virgin Western blot analysis showing the effect on the expression level. As shown in FIGS. 3A to 3C, when DFO alone was treated, the level of expression of the cadherin decreased, but when the red ginseng extract was treated, the expression level of the cadherin was increased depending on the treatment concentration of the red ginseng extract And DFO alone increased the expression level of visentin. However, when the red ginseng extract was treated, the expression level of visentin decreased depending on the treatment concentration of red ginseng extract.

Thus, the results of Examples 2-1 and 2-2 above show that red ginseng extract inhibits epithelial-mesenchymal transition.
