  • 본 연구는 식물성 모링가와 칡이 호르몬-민감성 전립선암에 어떤 효능을 나타내는지를 확인하고자 전립선 특이항원 및 항산화 활성과 항암활성을 분석하였다. 각각 에탄올로 추출하여 control, 0.1, 1.0, 10.0, 50.0mg/ml의 농도에서 DPPH 분석한 결과 칡은 50mg/ml에서 42.1%, 과라나는 73.9%의 소거율을 보여 유의적인 항산화 활성이 있음을 확인하였다(p<0.05). 호르몬에 민감한 인체 전립선암 세포주인 LNCaP에서 항암효과를 분석한 결과, 10mg/ml의 농도에서 모링가는 22±4.24%, 칡은 39.9±3.53%의 성장률을 나타냄으로써 분석한 두 가지 추출물 모두에서 뚜렷한 항암 효과가 있었고, 모링가 추출물이 칡 추출물보다 다소 높은 항산화 활성과 항암효과를 나타내었다. 이와 같은 결과는 천연 식물성 성분인 칡과 모링가가 호르몬에 민감한 전립선암의 예방과 치료에 새로운 항암제로서의 기초자료를 제공하는 것이며, 향후 이들 추출물 중에 어떤 특정성분이 이러한 역할을 하는지와 이에 대한 작용기작 및 안전성연구가 뒷받침되어야 할 것으로 사료된다.

  • Objectives : The purpose of this study was to investigate the anti-caner effect of Bee Venom and Melittin on the prostatic cancer cell(PC-3). The goal of study is to ascertain whether Bee Venom and Melittin inhibits the cell growth and cell cycle of PC-3, or the expression of relative genes and whether the regression of PC-3 cell growth is due to cell death or the expression of gene related to apoptosis. Methods : After the treatment of Pc-3 cells with Bee Venom and Melittin, we performed Fluorescence microscope, MTT assay, Western blotting, Flow cytometry, PAGE electrophoresis and Surface plasmon resonance analysis to identify the cell viability, apoptosis and gene related to apoptosis. Results : 1. Compared with Control cell, the inhibition of cell growth reduced in proportion with the dose of Bee Venom or Melittin($0{\sim}10{\mu}g/ml$) in PC-3. 2. In PC-3, Cell viabilities of Bee Venom or Melittin treatment was decreased significantly. 3. The nucli of Control cells were stained round and homogenous in DAPI staining, but those of PC-3 were stained condense and splitted. 4. In PC-3, apoptosis of Bee Venom or Melittin treatment was increased significantly. 5. Bax, Caspase-3 and P ARP of Bee Venom or Melittin treatment was increased significantly and Bcl-2 of Bee Venom or Melittin treatment was decreased significantly. Caspase-9 of Bee venom treatment was increased significantly. Conclusion : These results indicate that Bee Venom and Melittin inhibits the growth of prostate cancer cells, has anti-cancer effects by inducing apoptosis. We wish that the anti-cancer effects of Bee Venom and Melittin are used to clinical caner treatment.

  • We have studied the mechanism of action of TCDD on CYP1A1 promoter activity in both Hepa Ⅰ and MCF-7 cells using transient transfection system with p1A1-Luc reporter gene. When HDAC inhibitors, such as trichostatin A, HC toxin and a novel HDAC inhibitor, IN2001 were cotreated with TCDD to the cells transfected with plAt-Luc reporter gene, the basal promoter activity of CYP1A1 was increased by HBAC inhibitors. Also, in MCF-7 human breast cancer cells, HDAC inhibitors, such as IN2001 and trichostatin A increased the basal activity of CYP1A1 promoter but TCDD stimulated CYP1A1 promoter activity was not changed by HDAC inhibitors. And, in stably-transfected Hepa Ⅰ cells with p1A1-Luc, HDAC inhibitors increased the basal promoter activity only Also, we have investigated the effects of HDAC inhibitors on the human breast and prostate cancer cells in terms of cell proliferation and apoptosis based on SRB assay. IN2001 as well as trichostatin A inhibited the MCF-7, MDA-MB-231, MDA-MB-468, T47D, ZR75-1, PC3 cell growth dose-dependently. The growth inhibition of these cells with HDAC inhibitors was associated with profound morphological change, which suggests the HDAC inhibitors induced apoptosis of cells. The result of cell cycle analysis after 24h exposure of IN2001 showed G2/M cell cycle arrest in MCF-7 cells and apoptosis in T47D and MDA-MB-231 cells.

  • 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.

  • This study was performed to investigate the cell growth inhibitory effect of tissue cultured root of wild Panax ginseng C.A. Mayer (tcwPG). The human stomach carcinoma cell line, MKN 74, was incubated with 70% EtOH extract of tcwPG or Panax ginseng C.A. Mayer (PG) for 24 hrs. tcwPG inhibited cell growth at a concentration of $250{\mu}g/ml$. However, Panax ginseng extract did not inhibit cell growth at the same concentration. We also tested the ethyl acetate and $H_2O$ fractions of tcwPG. The inhibitory effect of the ethyl acetate fraction on cell proliferation in MKN 74 cells was more potent than that of the crude extract, and the inhibitory effect of the $H_2O$ fraction was less than that of the ethyl acetate fraction. When we separated tcwPG into polar and non-polar saponin fractions and then measured cell growth inhibition, the non-polar saponin in tcwPG exhibited cytotoxicity. To compare the effects of tcwPG on various cancer cell lines, we measured cytotoxicity in MKN 74 (stomach cancer cell line), SW 620 (colon cancer cell line) and PC 3 (prostate cancer cell line). All three cell lines showed cell growth inhibition, and the cell growth inhibitory effects were not quite different in the various cell lines. The non-polar saponins of tcwPG arrested PC 3 cells at G1-phase as did Panax ginseng.

  • 전립선암은 현대 남성들에게 걸리기 쉬운 질병으로 나이가 들수록 발병의 위험이 증가하는 질환으로 현재 우리나라에서도 점점 증가하는 추세이다. 전립선암 치료법들은 치료영역이 제한적이고 재발할 가능성이 높아 근본적인 치료법으로는 사용되지는 못하므로 새로운 전립선암 치료 방법이 필요하다. 이에 본 연구에서는 100 여 가지의 한약재 methanol 추출물을 이용하여 MTT 방법으로 전립선암 세포주인 PC-3 세포에 대한 항증식 효과를 탐색하였으며 그 결과, A. sylvestris가 가장 강한 항증식 활성을 보였다. A. sylvestris의 methanol 추출물로부터 저해물질을 분리하기 위하여 100% methanol에서 2-3일 추출하고 난 뒤, ethyl acetate로 추출하고 silica gel, reverse phase-18, Sephadex LH-20 등의 컬럼 크로마토그래피를 이용하여 분리하였다. 최종적으로 활성분획을 HPLC로 분리하고 $4^{\circ}C$에서 methanal 용액에서 입방체 형태의 결정을 얻었으며 NMR 분광법과 이화학적 특성을 분석한 결과, deoxypodophyllotoxin 으로 동정되었다. 순수 분리된 deoxypodophyllotoxin은 전립선암의 세포주 PC-3 세포에서 처리 농도와 처리 시간 의존적인 항증식 효과를 보였다.

  • Background: Urological cancers represent a major public problem associated with high mortality and morbidity. The pattern of these cancers varies markedly according to era, region and ethnic groups, but increasing incidence trends overall makes focused epidemiological studies important. The aim of the present study was to assess the incidence of most prevalent urological cancers in Iran from 2003 to 2009. Materials and Methods: The data for this study were obtained from the population-based Cancer Registry Center of the Iran Ministry of Health and Medical Education. Differences of mean age and age distributions of each cancer were compared between 2003 and 2009 in men and women. Results: Bladder cancer was the most common urologic cancer in both genders. The rate difference of age standardized ratio (ASR) of bladder and renal cell carcinoma in women were 1.54 and 2.01 percent per 100,000 population from 2003 to the 2009, respectively. In men, the rate difference of age standardized ratio of prostate, testis, kidney and bladder cancer was also 2.23, 1.2, 1.8 and 1.5 percent per 100,000 population from 2003 to 2009, respectively. The mean ages of patients in all cancers in both genders did not differ significantly through time (p value>0.05) but the distribution of ages of patients with bladder and prostate cancer changed significantly from 2003 to 2009 (p value<0.001). Conclusions: The results of present study suggest the general pattern and incidence of urological cancers in Iran are changing, the observed increase pointing to a need for urological cancer screening programs.

  • We investigated the effects of Oak smoke flavoring (OSF, Holyessing) on the growth of DU145 and PC-3 human prostate carcinoma cells. OSF treatment resulted in a concentration-dependent growth inhibition in both DU145 and PC3 cell lines. The anti-proliferative effect of OSF treatment was associated with the induction of apoptotic cell death which was confirmed by morphological change such as membrane shrinking, rounding up and chromatin condensation in DU145 and PC-3 cells. DNA flow cytometry analysis confirmed that OSF treatment increased population of apoptotic sub-G1 phase. Furthermore, we observed an increase of pro-apoptotic protein Bax expression and a decrease of anti-apoptotic protein Bcl-2 by OSF treatment in a dose-dependent manner. OSF also induced a proteolytic cleavage of specific target proteins such as poly(ADP-ribose) polymerase (PARP) and β-catenin proteins. The present results indicated that OSF-induced inhibition of human prostate carcinoma cell proliferation is associated with the induction of apoptosis.

  • Lung cancer remains a deadly disease with unsatisfactory overall survival. Resveratrol (Res) has the potential to inhibit growth of several types of cancer such as prostate and colorectal examples. In the current study, we evaluated in vitro and in vivo anticancer efficiency of Res in a xenograft model with A549 cells. Cell inhibition effects of Res were measured by MTT assay. Apoptotis of A549 cells was assessed with reference to caspase-3 activity and growth curves of tumor volume and bodyweight of the mice were measured every two days. In vitro cytotoxicity evaluation indicated Res to exert dose-dependent cell inhibition effects against A549 cells with activation of caspase-3. In vivo evaluation showed Res to effectively inhibit the growth of lung cancer in a dose-dependent manner in nude mice. Therefore, we believe that Res might be a promising phytomedicine for cancer therapy and further efforts are needed to explore this potential therapeutic strategy.
