  • 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.

  • Brine mineral water(BMW) has recently gained attention as a new water resource due to its biological activities. In this study, BMW from the Geumjin area(Gangneung-city, Korea) was evaluated for its growth inhibition, anti-metastasis and anti-angiogenesis activity against cancer cells. The in vitro cytotoxicity was measured by CCK assay, and the anti-metastasis activity was estimated by lung metastasis in vivo. The in vitro incubation of mouse splenic cells with BMW that had been diluted more than 4-fold showed no effect on the cell growth when compared to a control group. Additionally, BMW inhibited the growth of the EL-4, L5178Y-R and colon26-M3.1 cancer cell lines in a dose-dependent manner. In vivo evaluation of the anti-metastasis activity of BMW in BALB/c mice inoculated with the colon26-M3.1 cell line revealed dose-dependent inhibition in response to treatment with samples that were diluted by up to 9 times. Finally, treatment with BMW effectively suppressed the growth of vascular endothelial growth factor(VEGF) added human umbilical vein endothelial cells. Overall, these results suggest that BMW has anti-cancer activity.

  • Ginsenoside Rg3 is a bioactive ginseng constituent that has been reported to have diverse pathological and physiological effects, including anti-inflammatory and anti-metastatic activities. Metastasis is one of the most important factors involved in patients with melanoma. However, the molecular mechanism underlying the anti-metastatic activities of Rg3 in malignant melanoma cancer has not been fully elucidated. In this study, we have evaluated that Rg3 effectively inhibits metastasis of B16F10 melanoma cancer cells. We found that Rg3 significantly suppresses the migration, invasion, wound healing, and colony-forming abilities of B16F10 cells in a dose-dependent manner. Mechanistically, we demonstrate that Rg3 suppresses B16F10 cell metastasis by inhibiting MMP-13 expression. These results indicate that Rg3 suppresses the metastasis of B16F10 mouse melanoma cancer cells via MMP-13 regulation. Importantly, MMP-13 downregulation may influence the migration and invasion capabilities of melanoma cells and has been correlated with melanoma progression. Therefore, Rg3 is a potential therapeutic candidate that could be used to treat patients with metastatic melanoma.

  • The purpose of this study was to analyze inhibitory effects of anti-4-1BB monoclonal antibody on melanoma metastasis The 4-1BB (CD137) T cell molecule is a member of the TNF receptor family and its activation by either 4-1BB ligand or antibody induces T cell activation and growth. In the present study, administration of anti-4-1BB mAb induced inhibition of melanoma metastasis. Agonistic anti-4-1BB mAb induced not only CD$8^+$4-1BBT cells but also CD$8^+$IFN-${\gamma}$$^{+}$ T cell population. In the presence of anti-CD3 antibody, lymphocytes produced high levels of IFN-${\gamma}$ and low levels of IL-4 in anti-4-1BB mAb treated group. Exposure of melanoma cells to IFN-${\gamma}$ induced expression of MHC-I molecules. Thus, the increase in number of CD$8^+$T cells and enhanced MHC-I expression on B16F10 cells by augmented IFN-${\gamma}$ production in response to anti-4-1BB mAb may result in suppression of tumor growth and metastasis.s.

  • Purpose: This study was designed to investigate the anti-tumor metastasis by immunomodulating effects of extracts of Prunellae Spica. Methods: Antimetastatic experiment was conducted in vivo by using colon 26-M3.1 carcinoma. And we observed cytotoxicity of Prunellae Spica on colon 26-M3.1 carcinoma, L5178Y-R lymphoma cell, hela cell and macrophage. To observe the immnomodulating effects of Prunellae Spica, we estimated IL-6, IL-10, IL-12, TNF-${\alpha}$ from peritoneal macrophages. And we evaluated the activation of NK cell by using anti-asialo-GM1 serum. Results: We found that the administration of Prunellae Spica extracts significantly inhibited tumor metastasis in vivo. In an in vitro cytotoxicity analysis, cell growth are closer to 100% in case of colon 26-M3.1 carcinoma, L5178Y-R lymphoma cell, hela cell at low concentration. In case of macrophage, cell proliferation is closer to 100% less than $62.5{\mu}g/m{\ell}$ of Prunellae Spica extracts. The level of cytokine such as IL-6, IL-10, IL-12 which stimulates Prunellae Spica extracts was increased in dose-dependent manner compared to the control group. TNF-${\alpha}$ is hardly secreted less than $250{\mu}g/m{\ell}$ The depletion of NK cells by anti-asialo GM1 serum partly abolished the inhibitory effect of Prunellae Spica on tumor metastasis. Conclusion: Prunellae Spica appears to have considerable activity on the anti-metastasis by activation the immune system such as macrophage and NK cell.

  • Metastasis is one of the hallmarks of malignant neoplasms and is the leading cause of death in many cancer patients. A major challenge in cancer treatment is to find better ways to specifically target tumor metastasis. In this study, the anti-metastatic potential of the methanolic extract of Rhizophora apiculata (R.apiculata) was evaluated using the B16F-10 melanoma induced lung metastasis model in C57BL/6 mice. Metastasis was induced in C57BL/6 mice by injecting highly metastatic B16F-10 melanoma cells through the lateral tail vein. Simultaneous treatment with R.apiculata extract (10 mg/kg b.wt (intraperitoneal) significantly (p<0.01) inhibited pulmonary tumor nodule formation (41.1 %) and also increased the life span (survival rate) 107.3 % of metastatic tumor bearing animals. The administration of R.apiculata extract significantly (p<0.01) reduced biochemical parameters such as lung collagen hydroxyproline, hexosamine, uronic acid content, serum nitric oxide (NO), ${\gamma}$-glutamyl transpeptidase (GGT) and sialic acid levels when compared to metastasis controls. These results correlated with lung histopathology analysis of R.apiculata extract treated mice showing reduction in lung metastasis and tumor masses. Taken together, our findings support that R.apiculata extract could be used as a potential anti-metastasis agent against lung cancer.
