  • Objectives: This study was performed to investigate the anti-tumor effect of O. japonicus extracts on intrahepatic cholangiocarcinoma cell line SNU-1079. Methods: Cholangiocarcinoma SNU-1079 cells were treated with various concentrations of O. japonicus DW and EtOH extracts ($0-300{\mu}g/ml$) for 24, 48 or 72 h. Cell viability was evaluated through a PMS/MTS assay, and the apoptosis rate was examined through ELISA assay and flow cytometry analysis. The mRNA expression of apoptosis- and cell cycle progression-related genes (Bcl-2, Mcl-1, Bax, Survivin, Cyclin D1, and p21) was evaluated using real-time PCR, and the caspase activity was examined using immunoblot analysis. Results: O. japonicus extracts inhibited cell proliferation and increased apoptosis rate in both ELISA assay and flow cytometry analysis. O. japonicus extracts decreased Bcl-2, Mcl-1, Survivin, and Cyclin D1 mRNA expression and increased Bax mRNA level. O. japonicus extracts also increased Caspase-3 activation. Overall, O. japonicus DW extracts were more effective than EtOH extracts. Conclusions: O. japonicus inhibited cell proliferation and induced apoptosis in SNU-1079 cells via mitochondria -mediated intrinsic pathway, which leads to Caspase-3 activation. The results indicate that O. japonicus is a potential therapeutic herb with anti-tumor effect against intrahepatic cholangiocarcinoma.

  • Resveratrol (3,4,5-trihydroxy-trans-stilbene), a phytoalexin found in grape skin, grape products, and peanuts as well as red wine, has been reported to have various biological and pharmacological properties. The purpose of this study was to investigate the anti-obesity effect of resveratrol-amplified grape skin extracts on adipocytes. The anti-obesity effects of grape skin extracts were investigated by measuring proliferation and differentiation in 3T3-L1 cells. The effect of grape skin ethanol extracts on cell proliferation was detected by the MTS assay. The morphological changes and degree of adipogenesis of preadipocyte 3T3-L1 cells were measured by Oil Red-O staining assay. Treatment with extracts of resveratrol-amplified grape skin decreased lipid accumulation and glycerol-3-phosphate dehydrogenase activity without affecting 3T3-L1 cell viability. Grape skin extract treatment resulted in significantly attenuated expression of key adipogenic transcription factors, including peroxisome proliferator-activated receptor, CCAAT/enhancer-binding proteins, and their target genes (FAS, aP2, SCD-1, and LPL). These results indicate that resveratrol-amplified grape skin extracts may be useful for preventing obesity by regulating lipid metabolism.

  • Background: Apoptosis is a process of programmed cell death, and apoptosis defect results in serious diseases such as cancer. Apoptosis induction is one of the key mechanisms of anti-cancer agents. This study was aimed to find anti-prostate cancer compounds from marine-derived fungus Microsporum sp. Results: We found that physcion isolated from the fermentation broth extract of the marine fungus Microsporum sp. strain MFS-YL decreases the cell proliferation of PC3 human prostate cancer cells. Physcion induced cell apoptosis as determined by Annexin V/propidium iodide double staining. Physcion downregulated the anti-apopotoic proteins such as Ras, Bcl-xL, and Bcl-2, whereas upregulated the pro-apoptotic Bax. Physcion also activated caspase-3, caspase-8, and caspase-9. Conclusion: These results suggest that physcion from Microsporum sp. inhibits the proliferation of PC3 human prostate cancer cells via the pathway leading to apoptotic cell death. Physcion may be a potential candidate in the field of anticancer drug discovery against human prostate cancer.

  • Abies nephrolepis(Pinaceae) extracts were tested for determined immune system regulating activity based on antiinflammatory activity, antioxidant activity and anti-proliferative effect on HeLa cell line. The A. nephrolepis extracts increased dose-dependently anti-proliferation of HeLa cell line. The DM fraction of the extracts having anti-proliferatative effects of HeLa cell line was fractionalized four subfractions($D1{\sim}D4$). Inflammation-induced NO production was inhibited by D2 and D4 in LPS-activated RAW264.7 macrophages. And also, this fractions showed antioxidant activity examined by DPPH radical scavenging effects. These results suggest that the potential use of DM fraction of A. nephrolepis in chemoprevention and regulation overproduction of NO on pathogenic conditions. The mechanism of the inflammatory effects, however, must be evaluated through various parameters in the induction cascade of NO production.

  • It has been known that quercetin, a bioflavonoid widely distributed in fruits and vegetables as dietary-derived flavonoid and exert significant multiple biological effects such as antioxidant and anti-inflammatory, anti-tumor effects. In addition, it has been shown to have a chemoprotective role in cancer, though complex effects on signal transduction involved in cell proliferation and angiogenesis. The present study investigated whether quercetin can enhance antioxidant enzyme activity (glutathione peroxidase: GPx, superoxide dismutase: SOD, catalase: CAT) and regulate the reactive oxygen species (ROS) generation in the presence of vitamin E, L-ascorbic acid, reduced glutathione (GSH) on B16F10 murine melanoma cells. After 48h treatment of cells with quercetin in the presence of vitamin E, L-ascorbic acid, GSH, we measured the cytotoxicities by MTT assay. The cells exhibited a dose-dependent inhibition in their proliferation in the presence of vitamin E, L-ascorbic acid, GSH respectively. We also investigated the effects of antioxidant enzyme activity and ROS generation. The antioxidant enzyme activity of quercetin in the presence of vitamin E was stronger than GSH, L-ascorbic acid, the same treatments decreased ROS generation in B16F10 murine melanoma cells. Taken together, these result demonstrate that the antioxidant effect of quercetin can enhanced in the presence of vitamin E and it might plays an important role in anti-oxidative effects.

  • CPS219, a new concept compound composed of coffee (CO), Pueraria Tomsonii flower (PF), and Sambou bamboo saltTM (BS), was developed as a coffee beverage to alleviate menopausal symptoms. The purpose of this study is to evaluate the anti-oxidant and menopausal alleviating effects of CPS219 combined as the optimal ratio of each component selected through sensory evaluation and blind consumer test. For CPS219, the optimal ratio of CO, PF, and BS was determined to be 1:0.1:0.017 through various sensory evaluations and blind consumer tests. CPS219 significantly enhanced the superoxide dismutase-like activity compared to the CO or CO plus PF (CP). The proliferation of MCF-7 cells was considerably increased after 24 hours by treatment with CO, CP, or CPS219, but only CPS219 significantly boosted the proliferation of MCF-7 cells after 48 hours. Moreover, CPS219 had an estrogen-like effect by dramatically increasing the expression of estrogen receptor-β mRNA in MCF-7 cells but not CO and CP. Treatment of MCF-7 cells with CO, CP, or CPS219 did not cause any cytotoxicity. In conclusion, these findings imply that anti-oxidant and estrogen-like properties of CPS219 can be used to prevent and cure postmenopausal symptoms.

  • Cancer is an intractable disease for humans to overcome. Recently natural products or Oriental prescriptions have been on the spotlight to develop anticancer agents with little side-effects and good efficacy. KamikeKyuktang has been used for the treatment of cancer in Oriental medicine. However, its anti-cancer mechanism still remains unclear. KMKKTE is an ethanol extract of KamikeKyuktang composed of 12 medicinal herbs. Anti-proliferative effects of KMKKT was investigated on Lewis lung carcinoma cell (LLC) and A549 (human lung cancer cells). Half-maximal inhibition of the LLC and A549 cell proliferation by KMKKTE was found approximately 125㎍/㎖ and 250㎍/㎖, respectively. It also effectively inhibited the proliferation of HUVEC cells treated by bFGF and VEGF up to 30% of control at 125㎍/㎖ and the cell migration to 80% at 25 ㎍/㎖ in concentration dependent manner. Tube formation of HUVEC cells on matrigel also was significantly suppressed from 25㎍/㎖ of KMKKTE. Taken together, these results demonstrate that KMKKTE has antiangiogenic activity and be applied to angiogenesis dependent cancers.

  • Objectives : This study is aimed to elucidate anti-hepatoma activity of Coptis Chinensis Extract (CCE) and evaluate its effect on proliferation of human hepatoma Hep G2 cells. Methods : To identify CCE and control the quality, we performed fingerprinting by high-performance thin layer chromatography (HPTLC). To investigate effects of CCE on anti-hepatoma activity, we measured cytotoxicity against Hep G2 cells compared with treatment of paclitaxel and 5-fluorouracil (5-FU). To examine the mechanism of inhibitory effect of CCE on Hep G2 cell proliferation, cell cycle distribution was evaluated using fluorescent activated cell sorter (FACS) Result : CCE showed a significant effect that arrests Hep G2 cells at the G2/M phase of the cell cycle. CCE combined with paclitaxel inhibited synergistically cell growth of Hep G2 cells. Conclusion : CCE may present anticancer effects through inhibition of hepatocellular carcinoma (HCC) cell proliferation via G2/M arrest, and may be a useful anticancer agent for HCC.

  • Low power laser therapy is internationally certified and is known to be effective in stimulating DNA in living organisms, increasing protein synthesis and activating cell division, smoothing blood circulation, promoting cell activation, cell regeneration and function. It also has anti-inflammatory, anti-edemic, anti-fibrous dysplastic and neuralogic hyperfunctional effects. This study was intended to verify the effect of LED irradiation therapy on wound healing in cell and animal tests by applying LED irradiator using a laser and laser diode, which was independently designed and developed to emit beams of similar wavelength to that of a laser. This equipment was fabricated using a micro-controller and a high brightness LED, and designed to enable us to control light irradiation time, intensity and reservation. In case of cell proliferation experiment, each experiment was performed to irradiation group and non-irradiation group for tissue cells. MTT assay method was chosen to verify the cell increase of two groups and the effect of irradiation on cell proliferation was examined by measuring 590 nm transmittance of micro-plate reader. In the wound healing experiment, 1$cm^2$ wounds on the skin wound of SD-Rat(Sprague-Dawley Rat) were made. Light irradiation group and none light irradiation group divided, each group was irradiated one hour a day for 9 days. As a result, the cell increase of tissue cells was verified in irradiation group as compared to non-irradiation group. And, compared with none light irradiation group, the lower incidence of inflammation and faster recovery was shown in light irradiation group.

  • The cortex and root of Acnthopanax sessiliflorus, a herbal medicine, have been used for several diseases including cancer in Oriental countries. In the previous study, we showed that the cortex of this plant have anti-cancer activity. But its therapeutic efficacy of CORTEX ACANTHOPANAX RADICIS (CAR) is not clarified. For these reasons, we investigated immuno-potentiating and anti-cancer properties of CAR compared with CA, in terms of body and tumor weights, proliferation of thymocytes and tumor cells, and nitric oxide production from macrophages through in vitro and in vivo studies. In our results, administration of CAR reduced tumor mass and increased body weights. CAR also inhibited proliferation of tumor cells in vivo and in vitro dose-dependently. Thymocyte proliferation was accelerated by treatment with CAR and NO production was also promoted by CAR in vivo and vitro. In conclusion, we demonstrated that CAR is useful to treat for cancer as complementary or alternative medicine to Western medication, its therapeutic efficacy is involved in direct inhibition of tumor growth and immuno-potentiating activity.
