At once Medicine of East and West have the same purpose in treating, but there is a difference between the method of medical care and the view/slant on a disease each other. In the East Medicine, It is very difficult to explain the concept of Hwalhyulhwau but it is one of the way to cure cancer for long time. Be based on the theory of the East Medicine, research single medicine's anti-cancer effect among the natural products that has anti-cancer function. Moreover, for the purpose of finding new way to cure and prevent against cancer, we, the researchers, divided into four groups for this research: Group one: survey new substance with anti-cancer effects from natural products. Group two: research of anti-cancer mechanism through the experimental studies. Group three: research of immune responses in anti-canncer effects from natural products. Group four: research of the inhibitory effect on metastasis through the anti-angiogenesis. From the above results, we blended efficacious medidcines against cancer and made new prescriptions of Soam-I and Soam-II. Now, we are studying on these new prescriptions. We speculate that Soam-I and Soam-II may be used for a new conceptional anticancer therapy.

Anti-proliferation of methanol extract of Curcuma rhizome on oral squamous cell carcinoma (KB) and osteosarcoma (HOS) cells were investigated. In order to elucidate the involvement of telomerase inhibitory activity as a part of anti-proliferative effect of Curcuma rhizome on cancer cells, we measured telomerase activity in Curcuma rhizome extract-treated cancer cells. The concentration inhibited cell proliferation to 50% $(IC_{50})$ of the methanol extract of Curcuma rhizome against oral squamous cell carcinoma (KB) cells and osteosarcoma (HOS) cells were 21.30 ${\mu}g/ml$ and 39.3${\mu}g/ml$, respectively. The methanol extract of Curcuma rhizome showed inhibitory telomerase inhibitory effect which is required for cancer cell immortality. Therefore, it seems that the anticancer effect of methanol extract of Curcuma rhizome is at least partially due to telomerase inhibitory effect. Five fraction samples were prepared according to its polarity differences and analyzed anti-proliferative effects of each fraction samples on oral squamous cell carcinoma and osteosarcoma cells. Anticancer effect was observed in dichloromethane, and ethylacetate fractions. The highest anticancer effect was found in dichloromethane fraction which had $IC_{50}$ value of 23.3 ${\mu}g/ml$ and 10.5${\mu}g/ml$ against oral squamous cell carcinoma (KB) cells and osteosarcoma (HOS) cells, respectively.

This study was conducted to investigate the effect of mycelia of Lentinus edoes mushroom-cultured Astragalus membranaceus Bunge (LAM) on proliferation of cancer cell lines (Hep3B, MCF-7 and HeLa), sarcoma 180 (S-180), and anti-allergy. In an anti-cancer test using Hep3B (hepatic cancer cell), MCF-7 (breast cancer cell) and HeLa (uterine cancer cell), LAM extract showed higher antiproliferating effect than that of Astragalus membranaceus Bunge (AM) extract. In an anti-cancer testing using Hep3B cells and MCF-7 cells, LAM extract showed growth-inhibitory effect of 65.23% at 3 mg/mL and 69.23% at 5 mg/mL, respectively. In an anti-cancer testing using HeLa cells, LAM extract showed growth-inhibitory effect of 42.01% at 5 mg/mL. In addition, LAM showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitory rates against tumor cells were 47% for LAM and 37% for AM. LAM inhibited histamine release from rat peritoneal mast cells activated by compound 48/80. These results suggest that Lentinus edodes mushroom-cultured herb has an antiproliferating effect against cancer cell lines (Hep3B, MCF-7 and HeLa), S-180 tumor and will be beneficial in the treatment of allergic reaction.

Arctii Fructus (AF), which contains arctigenin (ARC) as a major constituent, is traditionally used as an anti-inflammatory medicine to treat inflammatory sore throat. Although several studies have proven its anti-inflammatory effects, there have been no reports on its use in inflammation related disorders such as obesity, cancer metastasis, and allergic responses. This study investigated the anti-obesity effect and anti-metastasis effect of AF and ARC. AF and ARC inhibited weight gain by reducing the mass of white adipose tissue in high fat diet (HFD)-induced obese mice. Serum cholesterol levels were also improved by AF and ARC. In in vitro experiments, AF and ARC decreased differentiation of white adipocytes. Furthermore, AF induced differentiation of brown adipocytes, which are able to consume surplus energy through non-shivering thermogenesis. Also, AF and ARC inhibited colon cancer and lung metastasis of colon cancer. They suppressed not only colorectal cancer cell progression by inhibiting cell growth, but also prohibited lung metastasis by regulating epithelial-mesenchymal transition (EMT), migration, and the invasion. These effects were confirmed in an experimental metastasis mouse model. In addition, AF and ARC inhibited mast cell mediated allergic responses. Collectively, our study suggests that AF and ARC might show inhibitory effects on inflammation related diseases, including obesity, cancer, cancer metastasis, and allergic responses.

Farrerol is a flavanone isolated from the traditional Chinese herb 'Man-shan-hong' (Rhododendron dauricum L.). Farrerol has been reported to have various bioactivities including anti-oxidant, anti-inflammation, and anti-fungal. However, anti-cancer effect of farrerol has not yet been reported in MCF-7 breast cancer cells. In the present study, we investigated the anti-cancer effect of farrerol on MCF-7 cells. Farrerol decreased viability and induced apoptosis of MCF-7 cells in a dose dependent manner. Ferrerol exhibited a significant anti-proliferation effect with a half-maximal inhibitory concentration (IC₅₀) values of 145.04±1.4 μM in MTT assay, when MCF-7 cells were treated with ferrerol for 48 h. Also, ferrerol induced apoptotic bodies of MCF-7 cells as evaluated by TUNEL assay and Annexin V/PI staining using FACS. By mechanism of action, ferrerol regulated the activation of p38 mitogen-activated protein kinase and altered the expression level of BAX, Bcl-2, and Poly ADP Ribose Polymerase in MCF-7 cells. In summary, our finding demonstrated that ferrerol has anti-cancer effect through regulating the activation and expression of apoptosis-related proteins in MCF-7 cells.

Recently, herbal flavonoids have been implicated for anti-cancer therapy. Flavonoids as a commonly known for their anti-oxidant activity, are contained in the herbal medicine as well as root of plants, vegetables, fruits, grains, tea, and wine. Kaempferol, a component of Polygonati rhizoma, a member of the herbal flavonoids, has been studied for anti-hypercholesterol, anti-hypertension and anti-diabetes. It is also known to be effective in anti-cancer therapy for breast, prostate and other type of cancers. However, the anti-cancer therapeutic mechanisms are pooly understood. Here, we investigated the molecular mechanism underlying kaempferol-induced anti-cancer effects using the human liver cancer cell lines, Hep3B, HepG2, and Sk-Hep-1, and human Chang liver cell as a control. As shown by the FACS analysis, measurement of caspase activity, DAPI and trypan blue staining, and DNA fragmentation assay, kaempferol induced apoptosis in the liver cancer cells with the greater potential in Hep3B cells than other liver cancer cells. In addition, we performed microarray analysis to profile the genome-wide mRNA expression regulated by kaempferol. Many of the apoptosis-related genes were significantly induced in kaempferol-treated Hep3B cells, in particular, the genes associated with MAPK cascade. Additionally, kaempferol induced the mRNA expression of genes involved in MKK7-JNK cascade, MKK3-p38 cascade, and caspase signaling pathway, which are all known to trigger apoptosis. Overall, our data suggest that kaempferol has anti-liver cancer effects by inducing apoptosis through the MKK7-JNK cascade, MKK3-p38 cascade, and caspase signaling pathways.

Lycopus lucid us Turcz is well known as traditional Chinese medicine, and it has been shown to exhibit antiinflammatory, -allergic and -oxidative effect. However, its anti-cancer properties have not been examined yet. In this study, we investigated the effect of the methanol extract of Lycopus lucid us Turcz on anti-cancer effect in MCF-7 human breast cancer cells. Treatment of Lycopus lucidus Turcz extract induced apoptosis and inhibition of cell proliferation in dose- and time-dependent manner. Apoptosis in the MCF-7 cells was characterized with the changes in nuclear morphology; decrease of Bcl-2 and caspase-7 expression; and increase of cleaved poly ADP-ribose polymerase(PARP). Furthermore, treatment of Lycopus lucidus Turcz extract caused the down-regulation of cell cycle-related protein including, cdk4, cyclin D1 and E2F-1. These results suggest that Lycopus lucidus Turcz might have the therapeutic value against human breast cancer cells.

Background: Cancer reseach is done in earnest world-wide, because cancer is one of most threatening diseases to humans. Orostachyos Herba is a widely used herb that has long been in use in Korea as an anti-inflammatory and anti-cancer therapy. The purpose of this study is to verify any anti-cancer effects on stomach and liver cancer in vitro. Materials & Methods: AGS and KATO III stomach cancer cells and Hep3B and HepG2 liver cancer cells, all obtained from Korean Cell Line Bank, were used. The boiled extract of Orostachyos Herba(20 and 40 microliters) were injected into cultures and observed at 0 hours, and at 24-hour intervals up to 96 hours. The destruction of stomach and liver cancer cells was measured through Trypan blue exclusion testing. The suppression on viability of stomach and liver cancer cells was observed, and anti-cancer mechanisms was examined by analyzing the cell cycle. Results: In morphologic change, AGS, KATO III, HepG2 and Hep3B showed some of the withdrawn and floating appearance that is typical in cellular imparment. AGS, KATO III, HepG2 and Hep3B showed more destruction of stomach cancer cells in each test group than in the control group to a statistically significant degree. Analysis of the cell cycle after introduction of Orostachyos Herba showed very little inhibition of divisions of all cell lines. Conclusions: This experiment suggests that Orostachyos Herba has some anti-tumor effects on stomach and liver cancer cells. Progressive research on Orostachyos Herba and it's anti-tumor effects will be needed to determine its practicability as a cancer treatment.

Cancers are one of the most dreaded diseases in human history and have been targeted by numerous trials including surgery, chemotherapy, radiation therapy, and anti-cancer drugs. Adult stem cells (ASCs), which can regenerate tissues and repair damage, have emerged as leading therapeutic candidates due to their homing ability toward tumor foci. Stem cells can precisely target malicious tumors, thereby minimizing the toxicity of normal cells and unfavorable side effects. ASCs, such as mesenchymal stem cells (MSCs), neural stem cells (NSCs), and hematopoietic stem cells (HSCs), are powerful tools for delivering therapeutic agents to various primary and metastatic cancers. Engineered ASCs act as a bridge between the tumor sites and tumoricidal reagents, producing therapeutic substances such as exosomes, viruses, and anti-cancer proteins encoded by several suicide genes. This review focuses on various anti-cancer therapies implemented via ASCs and summarizes the recent treatment progress and shortcomings.

Objectives : In this study, we investigate that Euphorbiae lathyridis Semen extract contributes to growth inhibitory effect and anti-cancer activity on the HT-29 human colon cancer cells. Methods : Euphorbiae lathyridis Semen was extracted from the Semen of the plant using 80% Methanol. The Euphorbiae lathyridis Semen extract was treated to different concentrations for 24 hr, 4Shr or 72hr. Growth inhibitory effect was analyzed by measuring FACS study and MTT assay. Cell apoptosis was confirmed by surveying caspases cascades activation using Westem blot. Results : Exposure to Euphorbiae lathyridis Semen extract (0.4mg/ml) results in an inhibitory effect on cell growth in HT-29 cells. Growth inhibition by Euphorbiae lathyridis Semen extract in HT-29 cells was related with the inhibition of proliferation and induction of apoptosis. The Euphorbiae lathyridis Semen extract induces DNA fragmentation in HT-29 cells. Furthermore, Euphorbiae lathyridis Semen extract induces cell apoptosis through the activation of caspases-3, caspase-9 and PARP cleavage. Conclusion : Euphorbiae lathyridis Semen extract induces apoptosis in human colon cancer cells, therefore, we suggest that Euphorbiae lathyridis Semen extract can be used as a novel class of anti-cancer drugs.
