Objectives The aim of this study is to investigate whether hwang-ryun-haedok-tang (HDT) affect proliferations of androgen-dependent LNCaP prostate cancer cells, androgen-independent PC-3, DU-145 prostate cancer cells, MCF-7 human breast cancer cells, A549, NCI-H292 human pulmonary cancer cells and K-562 human chronic myelogenous leukemia cells. Materials and Methods Effects of HDT on proliferations of each cancer cell line were investigated. 20,000 cells/well were plated in each well of 96-well culture plate. After 24 hrs, 0.01-10% of HDT in culture medium was added to cancer cells. The number of cells was counted by using SRB assay or direct cell counting method after 72 hours from drug treatment. Effect of baicalein or berebrine on proliferation was assessed according to the same method. Results (1) HDT inhibited proliferations of LNCaP, PC-3 and DU-145 prostate cancer cells. (2) HDT inhibited proliferation of MCF-7 breast cancer cells. (3) HDT also inhibited proliferations of A549, NCI-H292 pulmonary cancer cells and K-562 chronic myelogenous leukemia cells. (4) Baicalein and berberine also showed inhibitory effects on proliferations of prostate and breast cancer cells. Conclusion : HDT inhibited proliferations of human prostate, breast, pulmonary and blood cancer cells. These results suggest us the potential use of HDT as a chemopreventive or chemotherapeutic agent. Effect of HDT on human cancer should be further investigated using in vivo experimental models that can reflect pathophysiology of human cancer through another studies.

Effect of solvent extracts and juice supernatants from kimchis on the growth of various human cancer cells was studied, comparing with the actions on the normal cells. Inhibitory effect of kimchi extracts on[3H] thymidine incorporation n cancer cells was also investigated. The methanol extract, hexane extract and methanol soluble fraction (MSF) of 3-week fermented kimchi did not have growth inhibitory effect on Ac2F rat normal liver cells at the concentrations of 0.5~2%. However, marked decrease in the growth of AGS human gastric cancer cells was shown by the treatment of those extacts. The juice from the kimchi samples also suppressed the growth of K-562 human leukemia cells and MG-63 human osteosarcoma cells. Especially, the juice of 3-week fermented kimchi exhibited the strong growth inhibitory effect in MG-63 human osteosarcoma cells. At the photomicrographs, growth inhibition and morphological change of the cells treated with kimchi juice were observed. And the solvent extracts of 3-week fermented kimchi suppressed the growth of cancer morethan the extracts or juices from fresh and 6-week fermented kimchi. When AGS human gastric cancer cels were treated with the extracts of 3-week fermented kimchi, [3H] thymidine incorporation in the cells also decreased. These results showed that kimchi extracts and juices had growth inhibitory effects on human osteosarcoma, leukemia and gastric cancer cells, but had no toxicity to the normal cells. We suggest that kimchi might have anticancer effect in part due to inhibition of the growth and DNA synthesis of cancer cells.

Effect of solvent extracts and juice supernatants from kimchis on the growth of various human cancer cells was studied, comparing with the actions on normal cells. Inhibitory effect of kimchi extracts on [^3H] thymidine incorporation in cancer cells was also investigated. The methanol extract, hexane extract and methanol soluble fraction (MSF) of 3-week fermented kimchi did not have growth inhibitory effect on Ac2F rat normal liver cells at the concentrations of 0.5∼2%.

Human breast milk (HBM) provides neonates with indispensable nutrition. The present study evaluated the anti-cancer activity of diluted and pasteurized early HBM (< 6 weeks' lactation) on human breast cancer cell lines. The cell lines MCF7 and MDA-MB231 were exposed to 1 % HBM from the 1st, 3rd, and 6th weeks of lactation and exhibited reduced proliferation rates. As controls, breast cell lines (293T and MCF-10A), breast cancer cell lines (MCF-7 and MDA-MB-231), and $CD133^{hi}CXCR4^{hi}ALDH1^{hi}$ patient-derived human cancer stem-like cells (KU-CSLCs) were treated with prominent milk proteins ${\beta}$-casein, ${\kappa}$-casein, and lactoferrin at varying doses (10, 50, and $100{\mu}g$) for 24 or 48 hrs. The impact of these proteins on cell proliferation was investigated. Breast cancer cell lines treated with ${\kappa}$-casein and lactoferrin exhibited significantly reduced viability, in both a dose- and time-dependent manner. Interestingly, ${\kappa}$-casein selectively impacted only cancer (but not normal breast) cell lines, particularly the more malignant cell line. However, ${\beta}$-casein-exposed human breast cancer cell lines exhibited a significantly higher proliferation rate. Thus, ${\kappa}$-casein and lactoferrin appear to exert selective anti-cancer activities. Further studies are warranted to determine the mechanisms underlying ${\kappa}$-casein- and lactoferrin-mediated cancer cell-selective cytotoxic effects.

Human breast milk (HBM) provides neonates with indispensable nutrition. The present study evaluated the anti-cancer activity of diluted and pasteurized early HBM (< 6 weeks’ lactation) on human breast cancer cell lines. The cell lines MCF7 and MDA-MB231 were exposed to 1% HBM from the 1st, 3rd, and 6th weeks of lactation and exhibited reduced proliferation rates. As controls, breast cell lines (293T and MCF-10A), breast cancer cell lines (MCF-7 and MDA-MB-231), and CD133hiCXCR4hiALDH1hi patient-derived human cancer stem-like cells (KUCSLCs) were treated with prominent milk proteins β-casein, κ-casein, and lactoferrin at varying doses (10, 50, and 100 μg) for 24 or 48 hrs. The impact of these proteins on cell proliferation was investigated. Breast cancer cell lines treated with κ-casein and lactoferrin exhibited significantly reduced viability, in both a dose- and time-dependent manner. Interestingly, κ-casein selectively impacted only cancer (but not normal breast) cell lines, particularly the more malignant cell line. However, β-casein-exposed human breast cancer cell lines exhibited a significantly higher proliferation rate. Thus, κ-casein and lactoferrin appear to exert selective anti-cancer activities. Further studies are warranted to determine the mechanisms underlying κ-casein- and lactoferrin-mediated cancer cell-selective cytotoxic effects.

O. diffusa, C. appendiculata and F. thunbergii are reported to possess many pharmacological activities including anti-oxidant, anti-inflammatory, anti-hypertension, anti-diabetic and anti-cancer effects. However, their anti-cancer activities in human breast cancer have not been clearly elucidated yet. Objectives: In the present study, we compared the in vitro cytotoxic effects of single and complex treatment of O. diffusa, C. appendiculata and F. thunbergii in human breast cancer MDA-MB-231 cells. Methods: After we treated human breast cancer MDA-MB-231 cells with O. diffusa, C. appendiculata and F. thunbergii. we evaluated viability, growth inhibition, morphological changes, apoptotic body formation, measurement of the cell cycle and formation of DNA fragmentation of these cells. Results: We found that single treatment of O. diffusa and F. thunbergii could inhibit cell proliferation in human breast cancer MDA-MB-231 cells. However, complex treatment of O. diffusa, C. appendiculata and F. thunbergii had weak or no effect on the cell proliferation of MDA-MB-231 cells. The first, anti-proliferative effects of O. diffusa in MDA-MB-231 cells was associated with G2/M arrest of cell cycle and apoptotic cell death. The second, anti-proliferative effect of F. thunbergii in MDA-MB-231 cells was associated with apoptotic cell death. Conclusions: Taken together, these findings suggest that O. diffusa and F. thunbergii may be a potential chemotherapeutic agent for the control of human breast cancer cells, further studies will be needed to identify the molecular mechanisms.

Although the immense efforts have been made for cancer prevention, early diagnosis, and treatment, cancer morbidity and mor-tality has not been decreased during last forty years. Especially, lung cancer is top-ranked in cancer-associated human death. Therefore, effective strategy is strongly required for the management of lung cancer. In the present study, we found that novel daphnane diterpenoids, yuanhualine (YL), yuanhuahine (YH) and yuanhuagine (YG) isolated from the flower of Daphne genkwa (Thymelaeaceae), exhibited potent anti-proliferative activities against human lung A549 cells with the IC50 values of 7.0, 15.2 and 24.7 nM, respectively. Flow cytometric analysis revealed that the daphnane diterpenoids induced cell-cycle arrest in the G0/G1 as well as G2/M phase in A549 cells. The cell-cycle arrests were well correlated with the expression of checkpoint proteins including the up-regulation of cyclin-dependent kinase inhibitor p21 and p53 and down-regulation of cyclin A, cyclin B1, cyclin E, cyclin dependent kinase 4, cdc2, phosphorylation of Rb and cMyc expression. In the analysis of signal transduction molecules, the daphnane diterpenoids suppressed the activation of Akt, STAT3 and Src in human lung cancer cells. The daphnane diterpenoids also exerted the potent anti-proliferative activity against anticancer-drug resistant cancer cells including gemcitabine-resistant A549, gefitinib-, erlotinib-resistant H292 cells. Synergistic effects in the growth inhibition were also observed when yuanhualine was combined with gemcitabine, gefitinib or erlotinib in A549 cells. Taken together, these findings suggest that the novel daphnane diterpenoids might provide lead candidates for the development of therapeutic agents for human lung cancers.

Strong expression of neuron restrictive silencer factor (NRSF) has been observed in many aggressive types of cancer cells and mature neurons. However, the function of the neuron restrictive silencer element (NRSE)/NRSF system in KB human oral cancer cells is unknown. Findings from previous studies in our lab have demonstrated the importance of NRSF as a factor in regulationof cell proliferation of KB human oral cancer cells. Treatment of KB cells with NRSF siRNA resulted in signifi cant inhibitionof cell growth through repression of NRSF expression. In this study, in order to understand the NRSE/NRSF regulatory network in KB cells, we performed microarray analysis in KB cells treated with NRSF specifi c targeted siRNA. The expression profi les of several genes were further validated in KB cells treated with NRSF siRNA. Results of microarray analysis showed upregulation of 117 genes and down-regulation of 215 genes in KB cells treated with NRSF siRNA. Most of the up-regulated genes were involved in signal transduction, cell communication, cell cycle, and apoptosis;down-regulated genes were involved in RNA processing, neurogenesis, transcription factor activity, and synaptogenesis. NRSF is known as a transcriptional repressor for silencingof neuronal genes; however, according to our data, treatment of KB cells with NRSF siRNAresulted in down-regulation of more than 200 genes. As a result, genes identifi ed in this screen represent a novel control pathway via NRSF expression in KB oral cancer cells. Further investigation will be needed in order to defi ne the mechanism of gene regulation by expression of NRSF in KB human oral cancer cells.

The Maillard Reaction Products (MRPs) are chemical compounds which have been known to be effective in chemoprevention. Death receptors (DR) play a central role in directing apoptosis in several cancer cells. In our previous study, we demonstrated that (E)-2,4-bis(p-hydroxyphenyl)-2-butenal, a MRP product, inhibited human colon cancer cell growth by inducing apoptosis via nucle-ar factor-κB (NF-κB) inactivation and G2/M phase cell cycle arrest. In this study, (E)-2,4-bis(p-hydroxyphenyl)-2-butenal diacetate, a new (E)-2,4-bis(p-hydroxyphenyl)-2-butenal derivative, was synthesized to improve their solubility and stability in water and then evaluated against NCI-H460 and A549 human lung cancer cells. (E)-2,4-bis(p-hydroxyphenyl)-2-butenal diacetate reduced the viability in both cell lines in a time and dose-dependent manner. We also found that (E)-2,4-bis(p-hydroxyphenyl)-2-butenal diacetate increased apoptotic cell death through the upregulation of the expression of death receptor (DR)-3 and DR6 in both lung cancer cell lines. In addition to this, the transfection of DR3 siRNA diminished the growth inhibitory and apoptosis inducing effect of (E)-2,4-bis(p-hydroxyphenyl)-2-butenal diacetate on lung cancer cells, however these effects of (E)-2,4-bis(p-hydroxyphenyl)-2-butenal diacetate was not changed by DR6 siRNA. These results indicated that (E)-2,4-bis(p-hydroxyphenyl)-2-butenal diacetate inhibits human lung cancer cell growth via increasing apoptotic cell death by upregulation of the expression of DR3.

오문주,Saswati Paul,김승준,김준섭,윤종필,박혜원,김연정,류재천,이철우,김현미,최경희,김학주,황승용 한국바이오칩학회 2008 BioChip Journal Vol.2 No.4

Nonylphenol (NP), a byproduct of industrial synthesis, is quite similar to estrogen in structure, and is known as an environmental estrogen that induces estrogenic disturbances. It has been utilized in several industries for the manufacture of skin cleaning materials, kitchen detergents, cosmetics, fabric detergents, and ink binder. Due to its characteristic strong estrogenic potency, NP is capable of disrupting the reproductive hormone system. Exposure to NP for a prolonged period increases the chances of developing breast and lung cancers. In this study, we conducted a comparative study of expression profiles between HK (Human Kidney cell), MCF-7 (Human breast cancer cell), and LNCaP (Human prostate cancer cell) cells treated with NP at the value of IC20, using Agilent whole genome microarrays. After comparative analysis, we detected some specific expression patterns in each of the cell lines. However, the expression patterns from the HK-2 and MCF-7 cells are quite similar. Interestingly, estrogen receptor 1 and 2 genes were downregulated only in MCF-7 cells, whereas the androgen receptor (AR) gene evidenced overexpression in all 3 of the cell lines. The PDZK1 gene, which has been identified as an estrogen-responsive gene, has also been shown to be overexpressed in all 3 of the tested cell lines. The majority of differentially expressed genes in NP treatment were shown to be involved in cell proliferation, transcription, and signaling. These results may establish a framework for nderstanding the mechanisms underlying the toxicity of NP.
