Computational Exploration of Naturally Occurring Flavonoids as TGF-β Inhibitors in Breast Cancer: Insights from Docking and Molecular Dynamics Simulations and In-vitro Cytotoxicity Study. Chem Biodivers 2024; 21:e202301903. [PMID: 38623839 DOI: 10.1002/cbdv.202301903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 04/10/2024] [Accepted: 04/16/2024] [Indexed: 04/17/2024]
Abstract
Breast cancer is a global health concern, demanding innovative treatments. Targeting the Transforming Growth Factor-beta (TGF-β) signaling pathway, pivotal in breast cancer, is a promising approach. TGF-β inhibits proliferation via G1 phase cell cycle arrest, acting as a suppressor initially, but in later stages, it promotes progression by enhancing motility, invasiveness, and metastasis formation. This study explores naturally occurring flavonoids' interactions with TGF-β. Using molecular docking against the protein's crystal structure (PDB Id: 1PY5), Gossypin showed the highest docking score and underwent molecular dynamics simulation, revealing complex flexibility and explaining how flavonoids impede TGF-β signaling in breast cancer. ADMET predictions adhered to Lipinski's rule of Five. Insights into flavonoid-TGF-β binding offer a novel angle for breast cancer treatment. Flavonoids having a good docking score like gossypin, morin, luteolin and taxifolin shown potent cytotoxic effect on breast cancer cell line, MCF-7. Understanding these interactions could inspire flavonoid-based therapies targeting TGF-β to halt breast cancer growth. These findings pave the way for personalized, targeted breast cancer therapies, offering hope against this formidable disease.

Abstract
Tumors are one of the most life-threatening diseases, and a variety of cancer treatment options have been continuously introduced in order to overcome cancer and improve conventional therapy. Orostachys japonica (O. japonica), which is a perennial plant belonging to the genus Orostachys of the Crassulaceae family, has been revealed to exhibit pharmacological properties against various tumors in numerous studies. The present review aimed to discuss the biological actions and underlying molecular mechanisms of O. japonica and its representative compounds-kaempferol and quercetin-against tumors. O. japonica reportedly has antiproliferative, anti-angiogenic, and antimetastatic activities against various types of malignant tumors through the induction of apoptosis and cell cycle arrest, a blockade of downstream vascular endothelial growth factor (VEGF)-VEGFR2 pathways, and the regulation of epithelial-to-mesenchymal transition. In addition, emerging studies have highlighted the antitumor efficacy of kaempferol and quercetin. Interestingly, it was found that alterations of the mitogen-activated protein kinase (MAPK) signaling cascades are involved in the pivotal mechanisms of the antitumor effects of O. japonica and its two compounds against cancer cell overgrowth, angiogenesis, and metastasis. In summary, O. japonica could be considered a preventive and therapeutic medicinal plant which exhibits antitumor actions by reversing altered patterns of MAPK cascades, and kaempferol and quercetin might be potential components that can contribute to the efficacy and underlying mechanism of O. japonica.

Abstract
The rising burden of cancer worldwide calls for an alternative treatment solution. Herbal medicine provides a very feasible alternative to western medicine against cancer. This article reviews the selected plant species with active phytochemicals, the animal models used for these studies, and their regulatory aspects. This study is based on a meticulous literature review conducted through the search of relevant keywords in databases, Web of Science, Scopus, PubMed, and Google Scholar. Twenty plants were selected based on defined selection criteria for their potent anticancer compounds. The detailed analysis of the research studies revealed that plants play an indispensable role in fighting different cancers such as breast, stomach, oral, colon, lung, hepatic, cervical, and blood cancer cell lines. The in vitro studies showed cancer cell inhibition through DNA damage and activation of apoptosis-inducing enzymes by the secondary metabolites in the plant extracts. Studies that reported in vivo activities of these plants showed remarkable results in the inhibition of cancer in animal models. Further studies should be performed on exploring more plants, their active compounds, and the mechanism of anticancer actions for use as standard herbal medicine.

Ethanolic extract of Cordyceps cicadae exerts antitumor effect on human gastric cancer SGC-7901 cells by inducing apoptosis, cell cycle arrest and endoplasmic reticulum stress. JOURNAL OF ETHNOPHARMACOLOGY 2019; 231:230-240. [PMID: 30468850 DOI: 10.1016/j.jep.2018.11.028] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/05/2018] [Revised: 11/14/2018] [Accepted: 11/18/2018] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cordyceps cicadae (Miq.) Massee is a traditional Chinese medicine that has been used for approximately 1600 years in China. C. cicadae, a member of the Cordyceps genus, exerts a therapeutic effect on many diseases, such as cancer. OBJECTIVE This study aimed to evaluate the antineoplasmic activity of C. cicadae and to identify its molecular mechanism of cell death. MATERIALS AND METHODS The toxicity of the ethanolic extract of C. cicadae (EEC) against different cancer cell lines was determined through MTT assay. Human gastric cancer SGC-7901 cells were treated with EEC for 48 h. Cell morphology was examined by using an Olympus phase-contrast microscope. The cell apoptosis was quantified through Annexin V-FITC/PI staining. Cells were stained with PI and then subjected to flow cytometry for the investigation of cell cycle status. Cells were subjected to mitochondrial membrane potential (MMP) assay after incubation with JC-1 probes and to intracellular Ca2+ measurement through flow cytometry after incubation with Fluo-3 AM fluorescent probes. Western blot analysis was conducted to quantify the expression of proteins related to apoptosis, cell cycle and endoplasmic reticulum stress. High-performance liquid chromatography (HPLC) analysis was performed to analyse the biological activity components of EEC. RESULTS EEC suppressed the proliferation of SGC-7901 cells and induced the development of abnormal morphological features in a dose-dependent manner. Flow cytometry results indicated that EEC treatment caused cell apoptosis and arrested the cell cycle in the S phase. In addition, EEC treatment triggered MMP depolarization and Ca2+ overloading in the cytosol of SGC-7901 cells. Western blot analysis demonstrated that EEC increased Bax, AIF, caspase-8, caspase-6 and caspase-3 activities and decreased Bcl-2 activity. The release of cytochrome c from mitochondria was associated with mitochondrial dysfunction, which was caused by the activation of the cell surface receptor Fas and the cleavage of PARP. EEC-induced S phase arrest was associated with the up-regulation of E2F1, cyclin A2, cyclin E and p53 expression levels and the down-regulation of CDK2 expression. In addition, EEC increased the expression of endoplasmic reticulum stress-related proteins, such as calpain-1, caspase-12 and caspase-9. HPLC assay results suggested that EEC contained adenine, uridine, adenosine and N6-(2-Hydroxyethyl)-adenosine. CONCLUSION EEC inhibited the proliferation of SGC-7901 cells by inducing caspase-dependent apoptosis, arresting the cell cycle in the S phase and increasing endoplasmic reticulum stress. This study revealed that C. cicadae is a potential natural source of anticancer drugs.

Abstract
Background Colorectal malignant neoplasms is one of the leading causes of death in both men and women in the developed world and the incidence has recently increased markedly in South Africa. Studies have highlighted the beneficial effects of Amygdalin, a cyanogenic compound found in both peach and apricot kernels, in its ability to suppress the development of colon cancer. The focus of this study was to investigate the potential anti-proliferative properties of various apricot and peach kernels extractions from South Africa and China and to monitor alterations in cell cycle kinetics in colon cancer cells. Methods Studies were conducted on HT-29 colon cancer cells. The interactive role of three different kernel extractions on the modulation of cell proliferation, apoptosis and cell cycle progression was monitored over 24, 48 and 72 h periods. Results After 24 h, all extracts of the South African apricot kernels had a dose related bi-phasic proliferative effect on the HT-29 cells. It stimulated cell proliferation at the lowest and highest concentrations while at 500 μg/mL it inhibited cell proliferation. In contrast, after 72 h, the low concentration inhibited cell proliferation while the 500 μg/mL extracts stimulated cell proliferation. Morphological changes were observed in cells incubated with Chinese kernel extracts after 24 h and South African kernel treatment (1000 μg/mL) after 72 h. A possible intra-S-phase block after 24 and 48 h exposure to South African hydrophilic kernel extracts was observed. This transient block that is more concerned with tolerating and accommodating damage during replication rather than repairing it, could explain the initial anti-proliferative effects observed after 24 h exposure to the various Chinese kernel extract concentrations. Conclusion Abrogation of the block by exhaustion of the cyanide production, most likely allowed the cells to resume the cell cycle and continue into mitosis, whereas low ATP levels caused by the presence of amygdalin in the kernels, can also cause the induction of pycnosis or necrosis. These results highlight the possible mechanisms of growth inhibition by amygdalin containing extracts and may contribute towards the development of dietary anti-cancer therapies.

JAK2 regulation by licochalcone H inhibits the cell growth and induces apoptosis in oral squamous cell carcinoma. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 52:60-69.

Abstract
BACKGROUND Licochalconce (LC) H is an artificial compound in the course of synthesizing LCC in 2013. So far, few studies on the effects of LCH have been found in the literature. Despite progress in treatment modalities for oral cancer, the cure from cancer has still limitations. PURPOSE The effects of LCH were investigated on human oral squamous cell carcinoma (OSCC) cells to elucidate its mechanisms. STUDY DESIGN We explored the mechanism of action of LCH by which it could have effects on JAK2/STAT3 signaling pathway. METHODS To confirm LCH anti-cancer effect, analyzed were MTT assay, DAPI staining, soft agar, kinase assay, molecular docking simulation, flow cytometry and Western blotting analysis. RESULTS According to docking and molecular dynamics simulations, the predicted pose of the complex LCH and JAK2 seems reasonable and LCH is strongly bound to active JAK2 with opened activation loop. The LCH inhibitor is surrounded by specific ATP-binding pocket in which it is stabilized by forming hydrogen bonds and hydrophobic interactions. It is shown that LCH plays as a competitive inhibitor in an active state of JAK2. LCH caused a dose-dependent decrease in phosphorylation of JAK2 and STAT3. More interestingly, LCH suppressed JAK2 kinase activity in vitro by its direct binding to the JAK2. LCH significantly inhibited the JAK2/STAT3 signaling pathway, causing the down-regulation of target genes such as Bcl-2, survivin, cyclin D1, p21 and p27. In addition, LCH inhibited cell proliferation and colony formation of OSCC cells in a dose- and time-dependent manner, as well as induction of cell apoptosis through extrinsic and intrinsic pathway. The induction of apoptosis in OSCC cells by LCH was evident in the increased production of ROS, loss of mitochondrial membrane potential, release of cyto c, variation of apoptotic proteins and activation of caspase cascade. CONCLUSION LCH not only induces apoptosis in OSCC cells through the JAK/STAT3 signaling pathway but also inhibits cell growth. It is proposed that LCH has a promising use for the chemotherapeutic agent of oral cancer.

Abstract
OBJECTIVE Fruit of Phyllanthus emblica Linn. (PE) is widely consumed as a functional food and used as a folk medicine due to its remarkable nutritional and pharmacological effects. Mitomycin C (MMC) and cisplatin (cDDP) are the most widely used forms of chemotherapeutic drug, but their clinical use is limited by their genotoxicity to normal cells. We aimed to determine whether PE has potential to reduce the genotoxicity, while improving the anticancer effect, of MMC and cDDP. METHODS Cell proliferation was evaluated using the trypan blue exclusion assay and colony-forming assay. Genomic instability (GIN) was measured using the cytokinesis-block micronucleus assay. RESULTS Co-treatment (72 h) with PE at 20-320 μg/ml significantly enhanced the efficacy of MMC (0.05 μg/ml) and cDDP (1 μg/ml) against Colo205 colorectal cancer cells (P<0.05), and at 80-320 μg/ml significantly decreased MMC- and cDDP-induced GIN and multinucleation in normal colonic NCM460 cells (P<0.05). PE significantly decreased the mitotic index (P<0.01), blocked mitotic progression (P<0.05), and promoted apoptosis (P<0.01) in MMC- and cDDP-treated NCM460 cells, suggesting that PE-mediated inhibition of mitosis and induction of apoptosis may limit the division and survival of highly damaged cells. Also, PE was found to inhibit the clonal expansion of MMC- and cDDP-treated NCM460 cells (P<0.05) and decrease the heterogeneity of the surviving clones. CONCLUSIONS PE potentiates the anticancer efficacy of MMC and cDDP, while preventing their genotoxicity and inhibiting clonal expansions of unstable genomes in normal cells. These data suggest that PE has the potential to reduce the risk of secondary cancers induced by chemotherapeutics.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Medicines of the Yao ethnic group in China are a special branch of traditional Chinese medicine (TCM) and are well documented for use in disease prevention. According to an ethnopharmacological survey, there are 1392 species of medicinal plants that have been documented as Yao ethnomedicines and 104 of these species are used routinely. This study evaluated a partial collection of these 104 core plant species for their potential as anticancer agents. MATERIAL AND METHODS A literature study of scientific journals and books in the local language was conducted. Based on an ethnopharmacological survey, 16 plant species widely used in Yao ethnomedicine were collected and 64 plant extracts were prepared from these plants. in vitro cytotoxicity screening was conducted with a panel of four human cancer cell lines, lung cancer A549, breast cancer BT20 and MCF-7, bone cancer U2OS. The potential toxicity of the extracts was evaluated using two normal human cell lines, human peripheral lung epithelial cells (HPL1A) and human umbilical vein endothelial cells (HUVEC). Additionally, the 10 extracts that demonstrated cytotoxicity in cancer cells with an IC50 of less than 25.0µg/mL were examined for the ability to induce apoptosis in U2OS cells. RESULTS The up-to-date information regarding the traditional uses, pharmacological and biological activities, as well as the chemical constituents of the 16 plants are presented. Extracts from all 16 plants showed cytotoxicity against one to four of the human cancer cell lines and the cytotoxic effects of extracts from Melaleuca leucadendra, Stephania longa, Microsorium fortune and Bidens biternata were demonstrated for the first time. The highest anticancer potential was observed for extracts prepared from Melaleuca leucadendra Linn against all tested cancer cells (BT20, A549, U2OS, and MCF7) with an IC50 range of 3.1-32.7µg/mL. The selectivity index of the active samples varied from 0.1 to 25, and five extracts from Bidens biternata, Wedelia calendulacea, Stephania longa and Achras zapota showed significant selectivity against cancer cell lines versus normal cell lines. All tested extracts induced apoptosis in U2OS cells, and for the first time extracts from Melaleuca leucadendra and Microsorium fortune were shown to induce apoptosis. CONCLUSION We demonstrated the in vitro anticancer efficacy and safety of 16 medicinal plants that have been historically used in Yao ethnomedicine. This study provides evidence to assist the clinical practice of Yao ethnomedicine and the development of chemotherapeutic agents from extracts prepared from these plants.

Integr Cancer Ther 2017; 16:319-328. [PMID: 27252074 PMCID: PMC5759942 DOI: 10.1177/1534735416651492] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Revised: 04/18/2016] [Accepted: 04/23/2016] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The Chinese herbal mixture, Tien-Hsien liquid (THL), has been used as an anticancer dietary supplement for more than 20 years. Our previous studies have shown that THL can modulate immune responseand inhibit tumor growth. In this study, we further evaluated the effect of THL on anticancer immune response in mice vaccinated with γ-ray-irradiated tumor cells. METHODS The antitumor effect of THL was determined in mice vaccinated with low-tumorigenic CT-26-low colon cancer cells or γ-ray-irradiated high-tumorigenic CT-26-high colon cancer cells. The number of natural killer (NK) cells and T lymphocytes in the spleen was analyzed by flow cytometry. The tumor-killing activities of NK cells and cytotoxic T lymphocytes (CTLs) were analyzed by flow cytometry using YAC-1 and CT-26-high cells, respectively, as target cells. The levels of IFN-γ, IL-2, and TNF-α were determined by ELISA. RESULTS THL suppressed the growth of CT-26-high tumor in mice previously vaccinated with low-tumorigenic CT-26-low cells or γ-irradiated CT-26-high cells. THL increased the populations of NK cells and CD4+ T lymphocytes in the spleen and enhanced the tumor-killing activities of NK cells and CTL in mice vaccinated with γ-irradiated CT-26-high cells. THL increased the production of IFN-γ, IL-2, and TNF-α in mice vaccinated with γ-irradiated CT-26-high cells. CONCLUSION THL can enhance the antitumor immune responses in mice vaccinated with killed tumor cells. These results suggest that THL may be used as a complementary medicine for cancer patients previously treated with killed tumor cell vaccines, radiotherapy, or chemotherapy.

Abstract
Scutellaria baicalensis Georgi extract (SBGE) is used in traditional herbal medicine and has also been used clinically to ameliorate the symptoms of various inflammatory diseases and cancer. In women, breast cancer is one of the most common diseases and numerous women succumb to it. The present study was undertaken to investigate the mechanism responsible for the SBGE‑induced apoptosis of MCF‑7 human breast cancer cells. SBGE was administered to cells at concentrations between 100 and 500 mg/ml, and cell viabilities were identified using an MTT assay. B‑cell lymphoma 2 (Bcl-2) and Bcl-2 X‑associated protein (Bax) family members were identified by western blotting, and the mRNA expression levels of the pro‑apoptosis genes Fas, Fas ligand (FasL) and tumor necrosis factor (TNF)‑α were assessed by reverse transcription‑polymerase chain reaction. It was identified that SBGE treatment for 24 h inhibited MCF‑7 proliferation and increased the sub‑G1 phase ratio. SBGE suppressed mitochondrial membrane potentials and SBGE‑induced apoptotic cell death was identified to be associated with downregulation of Bcl‑2, but upregulation of Bax. SBGE‑activated caspases 3 and 9, and increased reactive oxygen species generation. However, SBGE had no effect on the expression levels of Fas, FasL or TNF‑α. Furthermore, mitogen‑activated protein kinase and C‑Jun N‑terminal kinase inhibitors inhibited SBGE‑induced cell death. These results suggested that SBGE be considered as an agent for the treatment of breast cancer.

Abstract
Hepatocellular carcinoma (HCC) has become a leading cause of cancer-associated mortality worldwide and is thus of great concern. Although various chemotherapeutic drugs are currently used for the treatment of HCC, severe side effects associated with these treatments have prompted interest in novel therapies, including the use of certain biological macromolecules such as polysaccharides. Several studies have shown that polysaccharides have anticancer and antiproliferative effects on HCC. Vascular endothelial growth factor, transforming growth factor β, epidermal growth factor and fibroblast growth factor may be effective targets for polysaccharides and may modulate tumor growth and immunity through increasing the expression levels of cytokines. The present review focuses on the ways in which growth factors contribute to the development of HCC, and on the anti-growth factor activities of natural and synthetic polysaccharides, as well as their effect on proinflammatory cytokines.

Abstract
BACKGROUND Various chemotherapeutic agents have been used largely for the treatment of salivary gland cancer. However, results are disappointing, and these agents can cause some serious side effects. Therefore, recent studies have focused on the possible roles of natural products to overcome these limitations. METHODS Salivary gland cancer cells treated with or without Convallaria keiskei (MECK) for 24 hours. Apoptotic changes were evaluated by live/dead assay, immunoblotting, and expression levels of caspase-3 and B-cell lymphoma-2 family member. RESULTS MECK significantly inhibited salivary gland cancer growth. At the molecular level, MECK dramatically reduced myeloid cell leukemia-1 (Mcl-1) in a translation-dependent manner and thereby induced apoptosis through Bax/Bid. Furthermore, we found that Mcl-1 could be a potential therapeutic target of MECK-induced apoptosis and its stability is regulated by extracellular signal-regulated kinases 1/2 (ERK1/2) signaling CONCLUSION MECK can be used as a safe and efficient therapeutic alternative for the treatment of salivary gland cancer. © 2015 Wiley Periodicals, Inc.

Abstract
The rhizome of Atractylodes lancea (A. lancea) (Thunb.) DC. (AL) is extensively used in Chinese, Thai, and Japanese traditional medicines as crude extracts/decoctions or a component in various herbal formulations. Various pharmacological activities of AL and its major constituents have been demonstrated in vitro, ex vivo, and in animal models. Results from the toxicity studies in animal models suggest safety profile of AL and its active constituents. Despite extensive use with positive impression in many diseases, there has not been a clinical study that can conclusively support its efficacy and safety profile in human. This review comprehensively summarizes current information on the pharmacological activities of AL and their active constituents including anticancer, anti-inflammatory, antimicrobial and antipyretic activities, as well as activities on central nervous, cardiovascular, and gastrointestinal systems.

Abstract
AIMS To investigate the antitumor effects of extracts from Oxytropis falcata on human hepatocellular carcinoma SMMC-7721 cells in vitro and in transplanted murine H22 tumors in vivo. METHODS Cell proliferation, cell cycle distribution and apoptosis in SMMC-7721 cells were determined and tumor growth inhibition in H22 tumors was investigated. Cell cycle distribution was analyzed by flow cytometry with propidium iodide (PI) and Annexin V-FITC/ PI double staining. RESULTS MTT assay revealed that essential oil and flavonoids of O. falcata (named EOOF and FOF) inhibited proliferation of SMMC-7721 cells in a dose-dependent manner. The IC50 value of EOOF and FOF were 0.115 and 0.097 mg·mL(-1), respectively. Cell cycle was arrested at G(1) phase, and induction of apoptosis occurred in SMMC-7721 cells when subjected to FOF. Growth inhibition in H22 solid tumors transplanted mice was significantly pronounced after being treated with FOF, and the inhibition ratio were 56.1% and 70.8% at the concentration of 30 and 60 mg·kg(-1). CONCLUSION The results suggest that FOF promotes apoptosis in SMMC-7721 cells and inhibits H22 tumor growth, resulting in a potential antitumor effect on hepatic cancer.

Abstract
Aim: Our previous works have demonstrated that Chinese herb medicine yanhusuo (Corydalis yanhusuo W. T. Wang) has strong anti-cancer proliferation effect in MDA-MB-231 cells. The goal of this study was to find out the synergic cytotoxicity effect of three natural compounds, tetrahydropalmatine (THP), berberine (Ber), and dehydrocorydaline (DHC), isolated from C. yanhusuo W. T. Wang. Materials and Methods: The IC50 of THP Ber and DHC in single use, as well as in combination use at fixed ratios and doses was measured by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay. Isobologram, combination index and modified coefficient of drug interaction (CDI) methods were used for evaluation the combination effects of THF! Ber, and DHC in different ratio and concentration. Results: The results indicated that the combination of THP and Ber shown the strongest anti-cancer cell proliferation effect at the ratio of 2:3 (Ber: THF the average CDI value was 0.5795). DHC and THP have additive cytotoxicity in MDA-MB-231 cells. However, there wasn’t any synergistic effect between Ber and DHC, and it even exhibited antagonistic effect when the percentage of DHC was >50%. Conclusion: Our findings suggested that the combination of THP and Ber might be beneficial for anti-proliferation of MDA-MB-231 breast cancer cells through a significant synergy effect.

Abstract
The treatment of cancer draws interest from researchers worldwide. Of the different extracts from traditional Chinese medicines, Tubeimoside 1 (TBMS 1) is regarded as an effective treatment for cancer. To determine the mechanism of TBMS 1, the shape/pattern of HepG2 cells based on the microscopic imaging technology was determined to analyze experimental results; then the fluorescent spectra method was designed to investigate whether TBMS 1 affected HepG2 cells. A three-dimensional (3D) fluorescent spectra sweep was performed to determine the characteristic wave peak of HepG2 cells. A 2D fluorescent spectra method was then used to show the florescence change in HepG2 cells following treatment with TBMS 1. Finally, flow cytometry was employed to analyze the cell cycle of HepG2 cells. It was shown that TBMS 1 accelerated the death of HepG2 cells and had a strong dose- and time-dependent growth inhibitory effect on HepG2 cells, especially at the G2/M phase. These results indicate that the fluorescent spectra method is a promising substitute for flow cytometry as it is rapid and cost-effective in HepG2 cells.

Abstract
For thousands of years, tonic herbs have been successfully used all around the world to improve health, energy, and vitality. However, their underlying mechanisms of action in molecular/systems levels are still a mystery. In this work, two sets of tonic herbs, so called Qi-enriching herbs (QEH) and Blood-tonifying herbs (BTH) in TCM, were selected to elucidate why they can restore proper balance and harmony inside body, organ and energy system. Firstly, a pattern recognition model based on artificial neural network and discriminant analysis for assessing the molecular difference between QEH and BTH was developed. It is indicated that QEH compounds have high lipophilicity while BTH compounds possess high chemical reactivity. Secondly, a systematic investigation integrating ADME (absorption, distribution, metabolism, and excretion) prediction, target fishing and network analysis was performed and validated on these herbs to obtain the compound-target associations for reconstructing the biologically-meaningful networks. The results suggest QEH enhance physical strength, immune system and normal well-being, acting as adjuvant therapy for chronic disorders while BTH stimulate hematopoiesis function in body. As an emerging approach, the systems pharmacology model might facilitate to understand the mechanisms of action of the tonic herbs, which brings about new development for complementary and alternative medicine.

AIM OF THIS STUDY To investigate the in vitro and in vivo anti-cervical cancer activity and the active constituents of the Thai medicinal plant recipe N040 selected from the MANOSROI III database. MATERIALS AND METHODS The extracts of recipe N040 and single medicinal plants in the recipe were prepared by hot water and methanol extraction, respectively. The n-hexane, ethyl acetate (EtOAc), n-butanol (n-BuOH) and water fractions of Caesalpinia sappan, the plant which showed the highest anti-proliferative activity were prepared by liquid-liquid partition extraction. The fraction which showed the highest anti-proliferative activity was further isolated for active constituents. Anti-proliferative activity of recipe N040, methanolic extracts, fractions of Caesalpinia sappan and brazilin, an active constituent on HeLa cell were investigated using sulforhodamine B (SRB) assay. Anti-oxidative activities including free radical scavenging and metal ion-chelating activities, as well as the phenolic and flavonoid contents of these fractions were also determined. The in vivo anti-cancer activity of recipe N040 on HeLa cell xenograft and the subchronic toxicity were performed in nude mice and rats, respectively. RESULTS AND CONCLUSIONS N040 showed the potent in vitro anti-proliferative activity on HeLa cell with the IC50 value of 0.11 µg/ml. Phytochemicals detected in the plants were steroids/triterpenoids, tannins, flavonoids, saponins and alkaloids. For the single plant, methanolic extract of Caesalpinia sappan gave the highest anti-proliferative activity with the IC50 of 33.46 µg/ml. EtOAc fraction of Caesalpinia sappan showed the highest anti-proliferative and free radical scavenging activities with the IC50 and SC50 of 17.81 and 21.95 µg/ml which were 1.88 and 0.83 folds of its methanolic extract and ascorbic acid, respectively. Poor metal chelating activity (MC50>500 µg/ml) was observed in methanolic extract and all fractions. The highest phenolic and flavonoid contents were observed in the methanolic extract. Brazilin, the known compound isolated from the EtOAc fraction exhibited potent anti-proliferative activity with the IC50 of 0.28 µg/ml which was higher than its methanolic extract and EtOAc fraction of 119.50 and 63.61 folds, respectively, but only 0.39 fold of the recipe extract N040. The tumor size of the HeLa cell xenograft nude mice treated with the recipe N040 at the dose of 44.50mg/kg body weight per day was significantly smaller (p<0.05) than that of the control with the relative tumor weight inhibition of 57.23% which was 0.65 fold of cisplatin. In the subchronic toxicity study, N040 given orally at the dose of 1000 mg/kg body weight per day for 90 days showed no alteration in body weight gain, hematology [except the increase mean corpuscular hemoglobin (MCH) in the treated male rats] and clinical blood chemistry (except the increase blood glucose in the treated male rats) both in female and male rats. Only minor lesions of the organs including lung, liver, kidney and small intestine were observed in both sexes. This study has demonstrated the synergistic effect of the plants composed in the recipe which resulted in the potent anti-cancer activity and confirmed the traditionally use of the recipe N040. In addition, this study has also suggested the compound brazilin isolated from Caesalpinia sappan for its high potential to be further investigated as a novel anti-cervical cancer drug.

Abstract
A high-throughput cell-based method was developed for screening traditional Chinese herbal medicines (TCHMs) for potential stem cell growth promoters. Mouse embryonic stem (mES) cells expressing enhanced green fluorescent protein (EGFP) were cultured in growth media supplemented with various TCHM extracts. The dosage-dependent effects of TCHM extracts on cell growth, including proliferation and cytotoxicity, were assessed via EGFP fluorescence measurement. Seven TCHMs were investigated, and among them Panax notoginseng (PN), Rhizoma Atractylodis macrocephalae, Rhizoma chuanxiong, and Ganoderma lucidum spores (GLS) showed potential to improve mES cell proliferation. Eleven mixtures of these four TCHMs were then studied, and the results showed that the mixture of PN and GLS had the strongest growth promoting effect, increasing the specific growth rate of mES cells by 29.5% at a low dosage of 0.01% (wt/vol) PN/GLS (P<0.01) and 34.2% at 0.1% (wt/vol) PN/GLS (P<0.05) compared to the control. The growth promoting effect of PN/GLS was further confirmed with ES cells cultured in spinner flasks. A 29.3-fold increase in the total cell number was achieved in the medium supplemented with 0.01% PN/GLS after 5 days, while the control culture only gave a 16.8-fold increase. This cell-based screening method thus can provide an efficient and high-throughput way to explore potential stem cell growth promoters from TCHMs.

Abstract
The purpose of this study was to investigate the pharmacological effect of fraction of Atractylodes lancea (Thunb.) DC. (A. lancea) extract. In this study, we isolated different polarity fractions, including petroleum ether (PE), ethyl acetate, n-butanol, and the remaining H2O fractions from the water extract of A. lancea. The antigastric cancer properties of the different fractions in BGC-823 and SGC-7901 cells were evaluated. Apoptotic cells were treated with PE fraction and stained with Hoechst 33342 and 5,5,6,6-tetrachloro-1,1,3,3-tetraethylbenzimidazolylcarbocyanine iodide. The cell cycle was analyzed via flow cytometry. The main compounds of PE fraction were determined by HPLC-ESI-MS. Results of this study showed that the PE fraction of A. lancea inhibited the growth of BGC-823 and SGC-7901 cells in a dose- and time-dependent manner. The morphological and mitochondrial transmembrane potential changes suggested that the cells showed preliminary apoptosis characteristics after treatment with the three different polarities. The main compounds of PE fraction include two sesquiterpene compounds: eudesm-4(15),7-diene-9α,11-diol and eudesm-4(15)-ene-7a,11-diol; three sesquiterpene lactone compounds: atractylenolid I, atractylenolid III and 3-β-acetyl-atractylenolid III and one polyacetylenic compound: 4,6,12-tetradecatriene-8,10-diyne-1,3,14-triol.

Abstract
OBJECTIVE To investigate the apoptotic effects and underlying molecular mechanisms of Celastrus orbiculatus (C. orbiculatus) extract in human hepatocellular carcinoma cells. METHODS Human hepatocellular carcinoma cells (HCCLM6) were treated with C. orbiculatus extract (COE) at different nontoxic concentrations (10, 20, 40, 80, and 160 microg/mL). The effect of COE on HCCLM6 viability was examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assays. Cellular apoptosis following COE treatment was assessed by flow cytometry and western blot analysis. RESULTS COE significantly inhibited cell viability and induced apoptosis of HCCLM6 cells in a dose-dependent manner. Apoptosis was accompanied by increased Bax expression and decreased Bcl-2 expression. In addition, COE treatment led to the release of cytochrome c, activation of caspase-3, and cleavage of poly (ADP-ribose) polymerase (PARP). Furthermore, activation of extracellular signal-regulated kinase (ERK), p38 kinase, and c-Jun N-terminal kinase (JNK) phosphorylation, and down-regulation of Akt phosphorylation was observed. CONCLUSION COE induces mitochondrial-mediated, caspase-dependent apoptosis in HCCLM6 cells, which might be attributed to the activation of mitogen-activated protein kinase (MAPK) and inhibition of Akt signaling pathways. These data suggest that COE may be a potential treatment for human hepatocellular carcinoma.

[PMID: 23323011 PMCID: PMC3531697 DOI: 10.3748/wjg.v18.i47.7079] [Citation(s) in RCA: 53] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2012] [Revised: 06/18/2012] [Accepted: 08/03/2012] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate the adjunct anticancer effect of Astragalus polysaccharides in H22 tumor-bearing mice.
METHODS: To establish a solid tumor model, 5.0 × 106/mL H22 hepatoma cells were inoculated subcutaneously into the right armpit region of Kunming mice (6-12 wk old, 18-22 g). When the tumors reached a size of 100 mm3, the animals were treated as indicated, and the mice were randomly assigned to seven groups (n = 10 each). After ten days of treatment, blood samples were collected from mouse eyes, and serum was harvested by centrifugation. Mice were sacrificed, and the whole body, tumor, spleen and thymus were weighed immediately. The rate of tumor inhibition and organ indexes were calculated. The expression levels of serum cytokines, P-glycoprotein (P-GP) and multidrug resistance (MDR) 1 mRNA in tumor tissues were detected using enzyme-linked immunosorbent assay, Western blotting, and quantitative myeloid-derived suppressor cells reverse transcription-polymerase chain reaction, respectively.
RESULTS: The tumor inhibition rates in the treatment groups of Adriamycin (ADM) + Astragalus polysaccharides (APS) (50 mg/kg), ADM + APS (100 mg/kg), and ADM + APS (200 mg/kg) were significantly higher than in the ADM group (72.88% vs 60.36%, P = 0.013; 73.40% vs 60.36%, P = 0.010; 77.57% vs 60.36%, P = 0.001). The spleen indexes of the above groups were also significantly higher than in the ADM group (0.65 ± 0.22 vs 0.39 ± 0.17, P = 0.023; 0.62 ± 0.34 vs 0.39 ± 0.17, P = 0.022; 0.67 ± 0.20 vs 0.39 ± 0.17, P = 0.012), and the thymus indexes of the ADM + APS (100 mg/kg) and ADM + APS (200 mg/kg) groups were significantly higher than in the ADM group (0.20 ± 0.06 vs 0.13 ± 0.04, P = 0.029; 0.47 ± 0.12 vs 0.13 ± 0.04, P = 0.000). APS was found to exert a synergistic anti-tumor effect with ADM and to alleviate the decrease in the sizes of the spleen and thymus induced by AMD. The expression of interleukin-1α (IL-1α), IL-2, IL-6, and tumor necrosis factor-α (TNF-α) was significantly higher in the ADM + APS (50 mg/kg), ADM + APS (100 mg/kg) and ADM + APS (200 mg/kg) groups than in the ADM group; and IL-10 was significantly lower in the above groups than in the ADM group. APS could increase IL-1α, IL-2, IL-6, and TNF-α expression and decrease IL-10 levels. Compared with the ADM group, APS treatment at a dose of 50-200 mg/kg could down-regulate MDR1 mRNA expression in a dose-dependent manner (0.48 ± 0.13 vs 4.26 ± 1.51, P = 0.000; 0.36 ± 0.03 vs 4.26 ± 1.51, P = 0.000; 0.21 ± 0.04 vs 4.26 ± 1.51, P = 0.000). The expression level of P-GP was significantly lower in the ADM + APS (200 mg/kg) group than in the ADM group (137.35 ± 9.20 mg/kg vs 282.19 ± 20.54 mg/kg, P = 0.023).
CONCLUSION: APS exerts a synergistic anti-tumor effect with ADM in H22 tumor-bearing mice. This may be related to its ability to enhance the expression of IL-1α, IL-2, IL-6, and TNF-α, decrease IL-10, and down-regulate MDR1 mRNA and P-GP expression levels.

Abstract
Chinese herb medicine (CHM) is the most commonly reported traditional Chinese medicine (TCM) modality. This study aimed to assess the prevalence and associated factors of CHM use in cancer patients in southwestern China. Cancer patients from eleven comprehensive cancer centers were asked to complete a structured questionnaire. Of 587 available replies, 53.0% used CHM. Multiple logistic regression analysis showed that educational level, stage of disease, duration of cancer since diagnosis, marital status, and previous use of CHM were strongly associated with CHM use after cancer diagnosis. The source of information about CHM was mainly from media and friends/family. CHM products were used without any consultation with a TCM practitioner by 67.5% of users. The majority used CHM to improve their physical and emotional well-beings and to reduce cancer therapy-induced toxicities. About 4.5% patients reported side effects of CHM. This survey revealed a high prevalence of CHM use among cancer patients. However, these patients did not get sufficient consultation about the indications and contradictions of these drugs. It is imperative for oncologists to communicate with their cancer patients about the usage of CHM so as to avoid the potential side effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhizoma Paridis, a traditional Chinese Medicine, was identified to be cytotoxic to cancer cells. The present study was designed to investigate the potential anti-angiogenic and antitumor effect of the ethanol extract of Rhizoma Paridis (RPE) in vitro and in vivo. MATERIALS AND METHODS The cytotoxic effect of RPE against human colon cancer Lovo cells and human umbilical vein endothelial cells (HUVECs) was examined using MTT assay. We also tested the effect of RPE on tube formation, migration, apoptosis and cell cycle of HUVECs. Moreover, Lovo subcutaneous xenograft was applied to study the antitumor and anti-angiogenesis effect of RPE in vivo. RESULTS RPE exerted a higher inhibition effect on the proliferation of HUVECs than Lovo cells. The tube formation and cell migration were also significantly inhibited in the presence of RPE in a concentration-dependent manner though the significant inhibition effects were observed at the cytotoxic dose. RPE induced cell apoptosis and G0-G1 cell cycle arrest of HUVECs. In vivo, significant tumor growth inhibition was observed in human colon cancer xenografts established by Lovo cells, accompanying by a marked decrease in MVD. CONCLUSIONS Our current study exhibited that RPE has a selective cytotoxity against HUVECs comparing to Lovo cells and also demonstrated significant anti-angiogenic effect in vivo.

Abstract
Traditional Chinese medicine (TCM) has recently yielded a number of chemical compounds with clinically significant anticancer activity. The theory of TCM formulas, however, unlike Western medicine, is based on the interactions of the various Chinese medicinal materials in the body, rather than the activity of a single purified chemical compound. Mechanisms for the possible synergistic anticancer effects of components in TCM formulas have recently been postulated. Advanced research on the clinical effects of TCM formulas, however, has been hampered by inconsistent dosage formulations and unreliable quality control. Scientific challenges in dosage formulation and methods for ensuring quality control of TCM products will be discussed.

Abstract
Background Astragalus polysaccharides (APS) are active constituents of Astragalus membranaceus. They have been widely studied, especially with respect to their immunopotentiating properties, their ability to counteract the side effects of chemotherapeutic drugs, and their anticancer properties. However, the mechanism by which APS inhibit cancer and the issue of whether that mechanism involves the reversal of multidrug resistance (MDR) is not completely clear. The present paper describes an investigation of the effects of APS on P-glycoprotein function and expression in H22 hepatoma cell lines resistant to Adriamycin (H22/ADM). Methods H22/ADM cell lines were treated with different concentrations of APS and/or the most common chemotherapy drugs, such as Cyclophosphamid, Adriamycin, 5-Fluorouracil, Cisplatin, Etoposide, and Vincristine. Chemotherapeutic drug sensitivity, P-glycoprotein function and expression, and MDR1 mRNA expression were detected using MTT assay, flow cytometry, Western blotting, and quantitative RT-PCR. Results When used alone, APS had no anti-tumor activity in H22/ADM cells in vitro. However, it can increase the cytotoxicity of certain chemotherapy drugs, such as Cyclophosphamid, Adriamycin, 5-Fluorouracil, Cisplatin, Etoposide, and Vincristine, in H22/ADM cells. It acts in a dose-dependent manner. Compared to a blank control group, APS increased intracellular Rhodamine-123 retention and decreased P-glycoprotein efflux function in a dose-dependent manner. These factors were assessed 24 h, 48 h, and 72 h after administration. APS down regulated P-glycoprotein and MDR1 mRNA expression in a concentration-dependent manner within a final range of 0.8–500 mg/L and in a time-dependent manner from 24–72 h. Conclusion APS can enhance the chemosensitivity of H22/ADM cells. This may involve the downregulation of MDR1 mRNA expression, inhibition of P-GP efflux pump function, or both, which would decrease the expression of the MDR1 protein.

Abstract
The effectiveness of cancer chemotherapy is often limited by the toxicity to other tissues in the body. Therefore, the identification of non-toxic chemotherapeutics from herbal medicines remains to be an attractive goal to advance cancer treatments. This study evaluated the cytotoxicity profiles of 364 herbal plant extracts, using various cancer and normal cell lines. The screening found occurrence of A549 (human lung adenocarcinoma) specific cytotoxicity in nine species of herbal plants, especially in the extract of Arctium lappa L. Moreover, purification of the selective cytotoxicity in the extract of Arctium lappa L. resulted in the identification of arctigenin as tumor specific agent that showed cytotoxicity to lung cancer (A549), liver cancer (HepG2) and stomach cancer (KATO III) cells, while no cytotoxicity to several normal cell lines. Arctigenin specifically inhibited the proliferation of cancer cells, which might consequently lead to the induction of apoptosis. In conclusion, this study found that arctigenin was one of cancer specific phytochemicals, and in part responsible for the tumor selective cytotoxicity of the herbal medicine.

Abstract
Based on a common belief, herbal medicine with the least possible side effects should be the center of attention in cancer care; however, in many cases they have not been properly studied with reliable clinical trials in human subjects. In this review, it was attempted to identify the available evidence on the use and clinical effects of herbs in cancer care. The research consists of two major parts including immunomodulator and chemopreventive herbal compounds whose mechanism, biological response, anticancer element of extract and related benefits were completely studied. Also, the safety of herbal anticancer compounds was discussed. Although the use of herbal medicines in treating cancer shows less chemotherapy-induced, toxicity, more researches are required to reach their full therapeutic potentials.

Abstract
AIM OF STUDY This study aimed to elucidate and compare the anti-metastatic mechanism of Tian-Xian liquid (TXL) and its bioactive components namely butanol (BU), ethyl-acetate (EA) and aqueous (WA) fractions on human colorectal cancer in vitro (HT-29 cancer cells) and in vivo (nude mouse xenografts). MATERIALS AND METHODS The anti-proliferative effects of TXL and its bioactive components in HT-29 cells were determined by MTT assay. Their modulations on the potential angiogenic and metastatic marker expressions on HT-29 cells and xenografts were investigated by real-time PCR and Western blot at transcriptional and translational levels, respectively. For the in vitro study, migration abilities of HT-29 cells were determined using wound healing assay. For the in vivo study, daily measurements of the tumor size and volume of the xenografts were also performed. RESULTS TXL, BU, EA and WA effectively inhibited the proliferation of HT-29 cells in a dose- and time-dependent manner. The IC(50) value of TXL on HT-29 cells was obtained after incubation with 1% (v/v) TXL for 4h; whereas IC(50) values were obtained for the following bioactive components: BU at 1.25% (v/v); EA at 5% (v/v); and WA at 0.3125% (v/v). It was found that 1% (v/v) TXL significantly down-regulated MMP2 and MMP7 expression at both transcriptional and translational levels and it reduced MMP9 and VEGF protein expression in vitro. TXL decreased the metastatic ability of HT-29 cells as demonstrated by wound healing assay. TXL and its bioactive fractions caused no significant changes in the body weight indicating lack of toxicity to the xenografts. CONCLUSIONS In summary, TXL multi-targeted to down-regulate the metastatic markers in both in vitro and in vivo models. However, the effects of its bioactive fractions were not obvious. This study profoundly elucidated the anti-proliferative mechanism of TXL, which is vital for the development of future anti-cancer regime in Chinese medicinal formulations.

[PMID: 21757251 DOI: 10.1016/j.lungcan.2011.06.001] [Citation(s) in RCA: 53] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2011] [Revised: 04/25/2011] [Accepted: 06/01/2011] [Indexed: 12/01/2022]
Abstract
Most non-small cell lung cancer (NSCLC) patients responding to gefitinib harbor activating mutations in the epidermal growth factor receptor (EGFR). However, the responsive cases eventually develop the resistance to gefitinib. Besides, K-ras mutations were identified as the primary resistance to gefitinib. We investigated whether Marsdenia tenacissima extract (MTE, trade name: Xiao-Ai-Ping injection) combined with gefitinib could overcome the resistance of NSCLC cells to gefitinib. NSCLC cell lines with different sensitivities to gefitinib were studied. Cell growth and apoptosis were evaluated by MTT assay and flow cytometry, respectively. The EGFR-related signaling molecule phosphorylation was assessed by Western blotting. We found that MTE inhibited cell growth in gefitinib-sensitive and -resistant cells. In gefitinib-resistant cells, the MTE→MTE+gefitinib (M→M+G) treatment was most potent over the concurrent administration of MTE and gefitinib (M+G) or gefitinib→gefitinib+MTE (G→G+M) treatment in cell growth inhibition and apoptosis induction. The M→M+G treatment significantly reduced the phosphorylation of EGFR downstream signaling molecules PI3K/Akt/mTOR and ERK, on which MTE and gefitinib alone had no obvious effects on the resistant cells. The M→M+G treatment attenuated c-Met phosphorylation in H460 and H1975 as well. Thus, we found that the M→M+G treatment improved the sensitivity of resistant NSCLC cells carrying T790M or K-ras mutations to gefitinib, suggesting that the M→M+G treatment may be a promising therapeutic strategy to overcome gefitinib resistance in NSCLC.

Abstract
Curcuma aromatica is a common Chinese herb for treating diseases with blood stasis and has been regarded as an anticancer herb in modern clinical practice. However, the anticancer effects and related molecular mechanisms of Curcuma aromatica remain unclear. In the present study, human colon carcinoma LS-174-T cell line with wild-type p53 was used as a model cell to evaluate the anticancer effects of aqueous extract of Curcuma aromatica (AECA). AECA inhibits LS-174-T cell proliferation in a dose- and time-dependent manner and colony formation in a dose-dependent manner. AECA treatment induces apoptosis accompanied by caspase-8, -9, and -3 activation in LS-174-T cells. Moreover, blocking the activities of these caspases with a specific inhibitor significantly protected LS-174-T cells from AECA-induced apoptosis. AECA treatment also induces G2/M phase arrest in LS-174-T cells. Expression of p53 was unchanged after AECA treatment; specific silence of p53 did not influence AECA-induced apoptosis and G2/M phase arrest. Further, the expression of cyclin B1 and CDK1 was reduced by AECA. This study suggests that AECA might be effective as an antiproliferative herb for colon carcinoma, the antitumor activity of AECA may involve both extrinsic and intrinsic apoptosis, and AECA induces G2/M phase arrest via downregulation of cyclin B1 and CDK1 and without the participation of p53.

Abstract
Use of herbal medicine in the treatment of liver cancer has a long tradition. The compounds derived from the herb and herbal composites are of considerable interest among oncologists. In the past, certain herbal compounds and herbal composite formulas have been studied through in vitro and in vivo as an anti-hepatocellular carcinoma (HCC) agent, enhancing our knowledge about their biologic functions and targets. However there is a significant distinction between the herbal medicine and the herbal production even though both are the plant-based remedies used in the practice. In this article, for the sake of clarity, the effective herbal compounds and herbal composite formulas against HCC are discussed, with emphasizing the basic conceptions of herbal medicine in order to have a better understanding of the prevention and treatment of HCC by herbal active compounds and herbal composite formulas.

Abstract
Although traditional Chinese medicine has benefitted one fifth of the world's population in treating a plethora of diseases, its acceptance as a real therapeutic option by the West is only now emerging. In light of a new wave of recognition being given to traditional Chinese medicine by health professionals and regulatory bodies in the West, an understanding of their molecular basis and highlighting potential future applications of a proven group of traditional Chinese medicine in the treatment of a variety of cancers is crucial – this is where their calling holds much hope and promise in both animal and human trials. Furthermore, the rationale for combining conventional agents and modern biotechnological approaches to the delivery of traditional Chinese medicine is an avenue set to revolutionize the future practice of cancer medicine – and this may well bring on a new dawn of therapeutic strategies where East truly meets West.

Abstract
UNLABELLED Angelica sinensis is a Chinese medicinal herb for treating gynecological and gastrointestinal disorders, and also in conjunction with cancer chemotherapy. AIM OF THE STUDY In the present study, the cytotoxic and anti-proliferative effects of three main Angelica sinensis phthalides, namely n-butylidenephthalide (BLP), senkyunolide A (SKA) and z-ligustilide (LGT), and their synergy on colon cancer HT-29 cells were investigated. Moreover, the results obtained in both human colon cancer HT-29 and normal colon CCD-18Co cells were compared for the investigation of selectivity. MATERIALS AND METHODS MTT and [3H] thymidine incorporation assays were used for the evaluation of cytotoxic and anti-proliferative effects, respectively. Interactions among phthalides were determined by median-effect analysis. RESULTS All three phthalides dose-dependently decreased cell viability more potently in HT-29 than in CCD-18Co cells. The IC50 values for inhibition of cell proliferation for SKA, LGT and BLP were 54.17+/-5.10, 60.63+/-6.79 and 236.90+/-18.22microM, respectively, in HT-29 cells. Angelica sinensis extract demonstrated significant synergy in inhibiting cell proliferation. CONCLUSIONS The three phthalides might have anti-cancer potential, yet the phthalides, in combination with other ingredients in Angelica sinensis extract, display significant synergy leading to a stronger anti-tumor effect.

Abstract
Purpose. To assess the efficacy of the best case series program methodology as a preliminary evaluation of complementary and alternative programs. Setting. East-West Cancer Center (EWCC) is a traditional oriental cancer center located in Daejeon, Korea. Cancer patients received Wheel balance therapy (WBT), which focuses on rediscovering homeostatic harmony with dietary therapy, metabolism-activating therapy, antiangiogenesis and immune system therapy, and controlled breathing and psychotherapy. Methods. Summaries of 6 cases in which patients showed longer survival without progression and were treated with WBT without conventional treatments were submitted for review to the National Cancer Institute (NCI) Office of Cancer Complementary and Alternative Medicine. Each case was then classified by the NCI review panel with pathologic confirmation of disease and radiologic confirmation of complete response or partial response not attributable to conventional treatments. Results. Two of 6 cases were classified as evaluable NCI best cases; the other 4 cases were classified as unevaluable. Except for a patient with squamous cell lung carcinoma, no patient showed further progression as of July 2007. Conclusion. The best case series program provides a preliminary evaluation of complementary and alternative medicine programs. But the method will only find treatments that have effects similar to those of conventional methods such as surgery, chemotherapy, and radiation therapy. Therefore, in future studies, BCSP reviewers should additionally consider assessing tumor dormancy and efficacy of combination therapies for Best Case qualification.
