  • Euonymus alatus(Thunb.) Sieb has been used for cancer theraphy such as Liver cancer, esophagus cancer, stomach cancer, and uterine cancer in folk. Eupolyphaga simemsis(ES) extracted from Euonymus alatus(Thunb.) Sieb increases HDL-C/TC ratio and LCAT activity. TGF-${\beta}$ and Insulin has been Knoen as factors to induce the supression of proliferation of Hep3B, Human hepatoblastoma cell. Plasma HDL3-C involved in carbohydrate methabolism in the liver was maintained in low level by Euonymus alatus(Thunb.) Sieb. The low level of plasma HDL3-C suppresses the transition from normal liver to Fat liver. Finally, this resuly in suppression of cancer in liver. In this study, Euonymus alatus(Thunb.) Sieb showed higher cell toxicity in hepatoblastoma cell(Hep3B) compared to the uterine cancer cell(HeLa). This means Euonymus alatus(Thunb.) Sieb seems not to affect in the all kinds of cancer. In future, we will study whether Euonymus alatus(Thunb.) Sleb have an effect on the liver cancer induced by virus and hepatocellular carcinoma. Also, the mechanims of suppression of cell proliferation in HCC need to investigated.

  • Objective : Euonymus alatus (Thunb.) Sieb (EA) is a traditional Korean herbal medicine, commonly used to treat tumors in Korea and China for centuries. Several earlier studies have indicated that EA exhibits anti-tumor properties, but its mechanism remains to be elucidated. In this study, we evaluated the molecular mechanism of EA in a human uterine leiomyomal smooth muscle cell (ULSMC) line. Methods : This study was evaluated by: (a), morphological changes by using acridine orange/ethidium bromide staining; (b), DNA fragmentation by TdT-mediated dUTP nick end labeling (TUNEL); and (c), sub-G1 cell analysis. Results : This study observed that EA treatment caused apoptotic cell death and depletion of intracellular glutathione (GSH) and that reduction of mitochondrial membrane potential was found to be involved in the initiation of apoptosis by EA. Conclusion : This results show that EA exerted clear cytotoxic effects and strongly inhibited the proliferation of ULSMC.

  • Euonymus alatus (Thunb.) Sieb., also known as the arrow tree in Korea, is a plant in East Asia used in traditional medicine and food. In particular, the wings of E. alatus are rich in phenolic compounds. This study evaluated the antioxidant, α-glucosidase inhibition, and anti-cancer activities of E. alatus wing extracts. The radical and hydrogen peroxide scavenging acitvities and reducing the power of 1,000 ㎍/mL E. alatus wing extracts, were similar to those of the positive control (0.1% BHT, 0.1% α-tocopherol). In addition, ethanol and methanol extract at 250 ㎍/mL showed 95.70 and 94.99% of α-glucosidase inhibition activity, respectively. The ethanol extract of E. alatus wings had the highest total polyphenol and flavonoid contents (867.8 mg% and 521.7 mg%, respectively). The E. alatus wing extracts significantly decreased the cell viability of LNCaP human prostate cancer cells (p<0.001), MDA-MB-231 human breast cancer cells (p<0.001), and HT-29 human colon cancer cells (p<0.001) in a dose-dependent manner. However, there was no significant effect on B16 mouse melanoma cells. Notably, the ethanol extracts showed higher cancer cell growth inhibitory activity in LNCaP and HT-29 cells than the other extracts. These results suggest that E. alatus wing extracts could have significant clinical applications, and our results can be used as basic data for future functional food material development.

  • The purpose of this study was to investigate the anti-inflammatory effects of water extract from Euonymus alatus (Thunb.) Sieb. (EAS) on the RAW 264.7 cells. To evaluate of anti-inflammatory of EAS, we examined the cytokine productions on lipopolysaccharide (LPS)-induced RAW 264.7 cells and also inhibitory mechanisms using Western blot. EAS reduced LPS-induced production of nitric oxide (NO), interleukin (IL)-1b, IL-6, IL-10 and tumor necrosis factor-a (TNF-a) in RAW 264.7 cells. EAS inhibited the activation of mitogen-activated protein kinases (MAPKs) such as p38, extracelluar signal-regulated kinase (ERK 1/2) and c-Jun NH2-terminal kinase (JNK) but not of inhibitory kappa B a (Ik-Ba) degradation in the LPS-stimulated RAW 264.7 cells. In conclusion, EAS down-regulated LPS-induced NO and cytokines production, which could provide a clinical basis.

  • Effects of polysaccharide fraction from Euonymus alatus Sieb(EPF) on the immune response of T-, B-lymphocytes and macrophages were examined in vitro and in vivo system. EPF (500 mg/kg) were administered p.o. twice a day for 5 days to C57BL/6 mice, and then the cells were separated from mice. EPF decreased the viability of thymocytes, but increased the viability of splenocytes in vitro and in vivo system. Also, the administration of EPF enhanced the population of helper T cell and cytotoxic T cell in thymocytes and did not affect the population of splenocytes. Furthermore, EPF enhanced the phagocytic activity and the production of nitric oxide in peritoneal macro phages in vivo system. These results suggest that EPF regulates an immune response via the enhancement of mature T lymphocytes and B lymphocytes viability and phagocytic activity of macrophages.

  • Objective : Many traditional herbal remedies exhibit several beneficial effects including anti-inflammation. Euonymus alatus (Thunb.) Sieb (EA), known as Gui jun woo in Korea, has long been used in folk medicine to regulate Qi (bodily energy) and blood circulation, relieve pain, eliminate stagnant blood, and treat dysmenorrhea in oriental countries. The exact mechanism of the anti-inflammatory action of Euonymus alatus (Thunb.) Sieb (EA), however, has not been determined. Methods: Since there is increasing evidence that nitric oxide (NO) plays a crucial role in the pathogenesis of inflammatory diseases, this study was undertaken to address whether the methanol (MeOH) extract and its fractions of the bark of EA could modulate the expression of inducible NO synthase (iNOS) in thioglycollate-elicited murine peritoneal macrophages and murine macrophage cell line, RA W264.7 cells. Results: Stimulation of the peritoneal macrophages and RAW264.7 cells with $interferon-\gamma\;(IFN-\gamma)$ and lipopolysaccharide (LPS) resulted in increased production of NO in the medium. However, the butanol (BuOH) fraction of the MeOH extract of EA barks showed marked inhibition of NO synthesis in a dose-dependent manner. The inhibition of NO synthesis was reflected in the decreased amount of iNOS protein, as determined by Western blotting. The BuOH fraction did not affect the viability of RA W264.7 cells, as assessed by methylthiazol-2-yl-2, 5-diphenyl tetrazolium bromide (MTT) assay; rather, it reduced endogenous NO-induced apoptotic cell death via inhibition of NO synthesis in RAW264.7 cells. On the other hand, the MeOH and BuOH fraction showed no inhibitory effect on the synthesis of NO by RAW264.7 cells, when iNOS was already expressed by the stimulation with $IFN-\gamma$ and LPS. Conclusion: Collectively, these results demonstrate that the MeOH and BuOH fraction inhibits NO synthesis by inhibition of the induction of iNOS in murine macrophages.

  • Background : Despite recent advances in cancer management, prognosis of ovarian cancer is poor. Anticancer effects of herbal medicine, such as Euonymus alatus Sieb, Oldenlandia diffusa (Willd.) Roxburgh, and Orostachys japonicus A. Berger, have been reported in treatment of ovarian and cervical cancers, but the systematic approaches to explain their molecular mechanism(s) have not yet been established. Objectives : To establish a basis of understanding for anti-cancer mechanisms of herbal medicine, we profiled protein expression in human ovarian and cervical cancer cells treated with the extracts from Euonymus alatus Sieb, Oldenlandia diffusa (Willd.) Roxburgh and Orostachys japonicus A. Berger. Methods : Human ovarian cancer cell line NIH:OVCAR-3, and human cervical cancer cell line HeLa were employed in the present study. Whole protein was obtained from the cells harvested at 48 hours after the treatment with herbal water-extract, and analyzed by 2DE-based proteomic approach. Results : Various changes of protein expression induced by the herbal treatment were monitored : down-regulation of molecular chaperone (calreticulin variant), glycolytic enzymes (D-3-phosphoglycerate dehydrogenase, glyceraldehyde 3-phosphate dehydrogenase and alpha-enolase), RNA processing molecules (hnRNP A2/B1), and antioxidant protein (peroxiredoxin 1). Conclusions : Repression of glycolysis has been accepted as the mechanism to increase anticancer reagent's effect. Thus, down-regulation of glycolytic enzymes by the herbal extracts suggested a possible synergistic effect of herbs in the presence of platinum-based therapeutics. In further study, as well as the synergistic effect of the herbs, it has to be further validated whether artificial regulation of hnRNP A2/B1 in ovarian cancer cells affects various cancer survival factors, since RNA processing can be interrupted by deranged expression of hnRNP subtypes, and it results in an inhibition of cancer cell growth.
