Saussurea lappa Clarke is a well-known transitional medicine in Asia including Korea, China and Japan. It has been reported that Clarke has diverse effects such as anti-viral, anti-inflammatory, anti-cancer in human gastric cells and human prostate cancer cells. However, the anti-cancer effects and the mechanism of actions of Saussurea lappa Clarke are still unknown in breast cancer. In this study, we observed that Saussurea lappa Clarke inhibits the cell growth in a dose- and time-dependent manner in highly-metastatic MDA-MB-231 breast cancer cells. In order to examine whether Saussurea lappa Clarke suppresses cell growth inducing apoptosis cell death or cell cycle arrest, we analyzed DNA contents and cell cycle distribution using a flow cytometer and western blotting in MDA-MB-231 cells. We suggest that Saussurea lappa Clarke dose not induced apoptosis and induced G2/M phase cell cycle arrest. Moreover, Saussurea lappa Clarke also decreased the expression level of metastasis-angiogenesis releated protein such as VEGF. However, dose not changed the expression level of metastasis related protease MMP-1 in highly-metastatic MDA-MB-231 breast cancer cells. Therefore, Saussurea lappa Clarke might be good and useful chemotherapy agent highly-metastatic breast cancer patients.

Saussurea lappa and Taraxacum mongolicum have been used for herbal medicinal treatments against cancers in East Asia. We performed this study to understand the molecular basis underlying the anti-tumor effects of two herbs and analyzed the effects of these medicinal herbs on proliferation and on expression of cell growth/apoptosis related molecules by using an AGS gastric cancer cell line. The treatments of Saussurea lappa dramatically reduced cell viabilities in a dose and time-dependent manner, but Taraxacum mongolicum did not. FACS analysis and Annexin V staining assay also showed that Saussurea lappa induces apoptotic cell death of AGS. Expression analyses via RT-PCR and Western blots revealed that Saussurea lappa increased expression of the p53 and its downstream effector p21/sup Waf1/, and that the both increased expression of apoptosis related Bax and cleavage of active caspase-3 protein. We also confirmed the translocation of Bax to mitochondria Collectively, our data demonstrate that Saussurea lappa induces growth inhibition and apoptosis of human gastric cancer cells, and these effects are correlated with down- and up-regulation of growth-regulating apoptotic and tumor suppressor genes, respectively.

Objectives : We performed this study to understand the molecular basis of the antitumor effect of Saussurea lappa, Pharbitis nil, Plantago asiatica and Taraxacum mongolicum, which have been used for cancer treatment in Korean traditional medicine. Design: We analyzed, the effect of these medicinal herbs on proliferation and apoptosis of tumor cells and its association with gene expression, We performed semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR) analysis of cell cycle- and apoptosis-related genes using a gastric cancer cell line AGS. Results : Cell counting assay and $[^3H]thymidine$ uptake analysis showed that Saussurea lappa and Pharbitis nil strongly inhibit cell proliferation of AGS in a dose-dependent manner. Interestingly, gene espression assay revealed that mRNA espression levels of c-Jun, c-Fos, c-Myc, and Cyclin D1 were markedly decreased by Saussurea lappa and Pharbitis nil. Furthermore, Saussurea lappa was identified to activate expression of the p53 tumor suppressor and its downstream effector $p21^{Wafl}$, which leads to $G_1$ cell cycle arrest and apoptosis. These observations suggest that the anticancer effect of Saussurea lappa and Pharbitis nil might be associated with their regulatory capability of tumor-related gene expression.

The root of Saussurea lappa includes sesquiterpene lactones such as costunolide and dehydrocostus lactone, and has been shown to be anti-tumorigenic with being used in traditional medicinal therapy in the Eastern Asia. However, the molecular basis of the effects of Saussurea lappa on fate of gastric carcinoma, which incur very frequently in the area, has not been well identified. In this study, the cytostatic effects of Saussurea lappa were examined using gastric AGS cancer cells. Cell viability was dramatically reduced by Saussurea lappa, in a dose-dependent manner. As time passed after its treatment, apoptotic population was increased and clearly showed G2-arrest. Being consistent, its treatment resulted in maintaining of G1 and S-phase cyclins D1, E, and A even until a significant apoptotic population was observed, for example, at 24h after treatment. However, G2/M phase cyclin B1 was reduced even at 12 h after treatment. In addition, its treatment increased expression of p53, p21/sup Wafl / cyclin dependent kinase inhibitor (CKI), and Bax, resulted in cleavages of procaspase 3 and poly ADP-ribose polymerase(PARP), indicating that such G2 arrest- and apoptosis-related molecules are involved. Therefore, these suggest that extracts of Saussurea lappa root may be a safer and effective reagent to deal with gastric cancers either by traditional herbal therapy or combinational therapy with conventional chemotherapy.

Saussurea Radix, the dried roots of Saussurea lappa Clark (Compositae), has been used in oriental traditional medicine for aromatic stomachic. Present study was carried out for the anticancer effect of Saussurea Radix. Bioassay-directed fractionation of Saussurea Radix led to the isolation of two sesquiterpenes, dehydrocostuslactone (1) and costunolide (2). The structures of 1 and 2 were elucidated by spectral methods (MS, IR, $^1$H and $^{13}$C NMR). These compounds showed a potent cell proliferation activity against human breast cancer cell MCF-7 and MDA-MB-453.

This study was carried out to investigate the antioxidative and antitumor activities of Saussurea lappa for the purpose of developing a functional food. The methanol extract of Saussurea lappa was fractionated with five solvents (hexane, chloroform, EtOAc, BuOH, water) and examined for antioxidative activities and xanthine oxidase inhibitory activity in addition to growth inhibitory activity of human cancer cell (HT-29, SNU-1, HeLa). Total phenol compound contents were higher in EtOAC fraction than other fractions. Also, electron donating ability was over 90% at $500{\mu}g/ml$ (93.1 %) and $1000{\mu}g/ml$ (94.3%). The hexane fraction revealed stronger nitrite scavenging ability than the positive control (ascorbic acid) and its abilities were 22.4% and 42.8% at $500{\mu}g/ml$ and $1000{\mu}g/ml$, respectively. Xanthine oxidase inhibitory activity had similar tendency to electron donating ability. The EtOAc fraction showed high inhibition to xanthien oxidase activities at $500{\mu}g/ml$(81.9%) and $1000{\mu}g/ml$(90.4%). In the antitumor activity test, the hexane fraction exhibited potent growth inhibition activity against HT-29, SNU-1 and HeLa cells. Therefore, we believe that Saussurea lappa can be developed into a functional food with antioxidant activity. Additional studies are required for the hexane and chloroform fractions of Saussurea lappa to develop them into therapeutic supplements for stomach cancer, colon cancer, and cervical cancer.

This study was performed to investigate the potential use of Saussurea lappa C.B. Clarke as a source of antioxidant agents. Various solvent fractionates from S. lappa C.B. Clarke roots were investigated for their anti-oxidative effectiveness. The contents of total phenolics and flavonoids were determined by the Folin-Ciocalteu's colorimetric and the aluminum nitrate method, respectively. Total phenolic and flavonoid contents of n-butanol soluble fractionates from S. lappa C.B. Clarke, 44.43 ${\mu}g$ gallic acid equilibrium (GAE)/g extract and 92.15 ${\mu}g$ quercetin equilibrium (QE)/g extract, respectively, were higher than those of other solvent fractionates. The n-butanol soluble fractionates of S. lappa C.B. Clarke (1,000 ppm) showed the strongest inhibitory potential on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and reducing power at 92.98% and 0.38, respectively. Thus, our data shows that the S. lappa C.B. Clarke plant may help prevent antioxidative stress.

We investigated the total phenolic and flavonoid contents and the antimicrobial activity of ethanol extracts obtained from Saussurea lappa C.B. Clarke. The ethanol extracts of S. lappa C.B. Clarke were fractionated with various solvents (n-hexane, chloroform, and n-butanol). The antimicrobial activity of S. lappa C.B. Clarke was examined by disc-diffusion and micro-dilution susceptibility assays with six food-borne pathogens, and compared to that of the synthetic antibiotics. It is found that the S. lappa C.B. Clarke ethanol extract and n-hexane fraction have strong activity against B. cereus and V. parahaemolyticus strains compared to ampicillin. The inhibitory concentration ($IC_{50}$) values of hexane fraction against L. monocytogenes, B. cereus, and B. subtilis were 62.5, 250 and 500 ppm, respectively. Therefore, these data suggest that S. lappa C.B. Clarke may be useful as antimicrobial agents against food-borne pathogens.
