Background: In recent years, natural products have received great attention for cancer prevention owing to their various health benefits, noticeable lack of toxicity and side effects, and the limitations of chemotherapeutic agents. Andrographolide, a labdane diterpenoid is a principal bioactive constituent of Andrographis paniculata Nees, exhibits significant anticancer activity. Objective: The efficacy of andrographolide on colon cancer cells is yet to be elucidated completely. Therefore, we investigated the anticancer efficiency of andrographolide in colon cancer DLD1 cell line. Methods: Antiproliferative activity of andrographolide on DLD1 cells was evaluated by MTT assay, LDH release assay, morphological analysis and colony formation assay. Induction of apoptosis was determined by DAPI staining, Annexin V-FITC staining assay, and caspase-3 activation assay. Role of andrographolide induced cellular reactive oxygen species (ROS) and its association with apoptosis induction in DLD1 cells was elucidated by DCFDA dye. Synergistic ability of andrographolide with 5- fluorouracil (5-FU) and paclitaxel (PTX) was evaluated by MTT assay. Results: Results of the present study indicated that andrographolide declined cell viability of DLD1 cells in a concentration and time-dependent manner. Andrographolide induced apoptosis via nuclear condensation, phosphatidylserine externalization and caspase-3 activation. It also augmented cellular ROS levels which were in turn associated with apoptosis induction in DLD1 cells. Moreover, andrographolide displayed synergistic activity with 5-FU and PTX against DLD1 cells. Conclusion: The present study showed that andrographolide demonstrated antiproliferative and apoptotic properties, moreover it also displayed synergistic effect with chemotherapeutic drugs in colon cancer DLD1 cells.

The effect of Haeamtang (HAT) on the colon cancer HT-29 cells was investigated in this study. A water extract of HAT significantly decreased the number of HT-29 cells in a dose-and time-dependent manner as determined by a MTT assay. Flow cytometry results revealed a dose- and time-dependent increase of dead cells in HT-29 cells treated with HAT extract. The anticancer activity of the H AT extract is attributed to apoptosis induced in HT-29 cells, which was demonstrated by increased caspase-3 activity and poly-ADP-ribose polymerase fragmentation. A selective caspase inhibitor, z-VAD-fmk, inhibited the HAT-induced cell death. Taken together, these results demonstrate that HAT extract induces apoptosis in HT-29 cells.

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and most current therapies are of limited efficacy.Trigonella foenum(Fenugreek) is a traditional herbal plant with antitumor activity, although the mechanisms of its activity remain unclear. Herein, a crude methanol extract was prepared from Fenugreek seeds (FCE) and its anticancer mechanism was evaluated, using HepG2 cell line. Growth-inhibitory effect and apoptosis induction of HepG2 cells were evidenced by MTT assay, cell morphology alteration, apoptosis enzyme-linked immunosorbent assay, flow cytometric analysis, caspase-3 activity, and expression of p53, proapoptotic protein, Bax, and proliferating cell nuclear antigen (PCNA) after (100∼500 μg/mL) FCE treatment for 48 h. Furthermore, FCE was analyzed by Chromatography-Mass Spectrometry (GC/MS). Our results revealed that FCE treatment for 48 h showed a cytotoxic effect and apoptosis induction in a dose-dependent manner that was mediated by upregulation of p53, Bax, PCNA, and caspase-3 activation in HepG2 cells. GC-MS analysis of FCE showed the presence of fourteen bioactive compounds such as Terpenoids and Flavonoids, including two main constituents with anticancer activity, Squalene and Naringenin (27.71% and 24.05%), respectively. Our data introduced FCE as a promising nontoxic herbal with therapeutic potential to induce apoptosis in HepG2 cells through p53, Bax, and PCNA upregulation in caspase-3 dependent manner.

Abstract Background Colon cancer is a malignant gastrointestinal tumour with high incidence, mortality and metastasis rates worldwide. Aloe-emodin is a monomer compound derived from hydroxyanthraquinone. Aloe-emodin produces a wide range of antitumour effects and is produced by rhubarb, aloe and other herbs. However, the mechanism by which aloe-emodin influences colon cancer is still unclear. We hope these findings will lead to the development of a new therapeutic strategy for the treatment of colon cancer in the clinic. Methods We identified the overlapping targets of aloe-emodin and colon cancer and performed protein–protein interaction (PPI), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. In addition, we selected apoptosis pathways for experimental verification with cell viability, cell proliferation, caspase-3 activity, DAPI staining, cell cycle and western blotting analyses to evaluate the apoptotic effect of aloe-emodin on colon cancer cells. Results The MTT assay and cell colony formation assay showed that aloe-emodin inhibited cell proliferation. DAPI staining confirmed that aloe-emodin induced apoptosis. Aloe-emodin upregulated the protein level of Bax and decreased the expression of Bcl-2, which activates caspase-3 and caspase-9. Furthermore, the protein expression level of cytochrome C increased in a time-dependent manner in the cytoplasm but decreased in a time-dependent manner in the mitochondria. Conclusion These results indicate that aloe-emodin may induce the apoptosis of human colon cancer cells through mitochondria-related pathways.

Background: We studied the effect of three plant extracts (Glycyrrhiza glabra, Paeonia lactiflora, Eriobotrya japonica) and six of their major secondary metabolites (glycyrrhizic acid, 18β glycyrrhetinic acid, liquiritigenin, isoliquiritigenin, paeoniflorin, ursolic acid) on the multidrug resistant human colon cancer cell line Caco-2 and human leukemia cell line CEM/ADR 5000 as compared to the corresponding sensitive cell line CCRF-CEM, and human colon cancer cells HCT-116, which do not over-express ATP-binding cassette (ABC) transporters. Methods: The cytotoxicity of single substances in sensitive and resistant cells was investigated by MTT assay. We also applied combinations of extracts or single compounds with the chemotherapeutic agent doxorubicin or doxorubicin plus the saponin digitonin. The intracellular retention of the ABC transporter substrates rhodamine 123 and calcein was examined by flow cytometry to explore the effect of the substances on the activity of ABC transporters P-glycoprotein and MRP1. Real-time PCR was applied to analyse the gene expression changes of ABCB1, ABCC1, caspase 3, caspase 8, AhR, CYP1A1, and GSTP1 in resistant cells under the treatment of the substances. Results: All the substances moderately inhibited cell growth in sensitive and resistant cells to some degree. Whereas ursolic acid showed IC50 of 14 and 22 µM in CEM/ADR 5000 and Caco-2 cells, respectively, glycyrrhizic acid and paeoniflorin were inactive with IC50 values above 400 μM. Except for liquiritigenin and isoliquiritigenin, all the other substances reversed MDR in CEM/ADR 5000 and Caco-2 cells to doxorubicin. Ue, ga, 18ga, and urs were powerful reversal agents. In CEM/ADR 5000 cells, high concentrations of all the substances, except Paeonia lactiflora extract, increased calcein or rhodamine 123 retention in a dose-dependent manner. In Caco-2 cells, all the substances, except liquiritigenin, retained rhodamine 123 in a dose-dependent manner. We also examined the effect of the plant secondary metabolite (PSM) panel on the expression of ABCB1, ABCC1, caspase 3, caspase 8, AhR, CYP1A1, and GSTP1 genes in MDR cells. Conclusions: The extracts and individual PSM could reverse MDR in CEM/ADR 5000 and Caco-2 cells, which overexpress ABC transporters, in two- and three-drug combinations. Most of the PSM also inhibited the activity of ABC transporters to some degree, albeit at high concentrations. Ue, ga, 18ga, and urs were identified as potential multidrug resistance (MDR) modulator candidates, which need to be characterized and validated in further studies.

Silver nanoparticles are used in many commercial products in daily life. Exposure to nanosilver has hepatotoxic effects in animals. This study investigated the cytotoxicity associated with polyvinylpyrrolidone-coated nanosilver (23.44 ± 4.92 nm in diameter) exposure in the human hepatoma cell line (HepG2) and normal hepatic cell line (L02), and the molecular mechanisms induced by nanosilver in HepG2 cells. Nanosilver, in doses of 20–160 μg mL−1 for 24 and 48 h, reduced cell viability in a dose- and time-dependent manner and induced cell membrane leakage and mitochondria injury in both cell lines; these effects were more pronounced in HepG2 cells than in L02 cells. Intracellular oxidative stress was documented by reactive oxygen species (ROS) being generated in HepG2 cells but not in L02 cells, an effect possibly due to differential uptake of nanosilver by cancer cells and normal cells. In HepG2 cells, apoptosis was documented by finding that ROS triggered a decrease in mitochondrial membrane potential, an increase in cytochrome c release, activation of caspase 3 and caspase 9, and a decrease in the ratio of Bcl-2/Bax. Furthermore, nanosilver activated the Fas death receptor pathway by downregulation of nuclear factor-κB and activation of caspase 8 and caspase 3. These results suggest that apoptosis induced by nanosilver in HepG2 cells is mediated via a mitochondria-dependent pathway and the Fas death receptor pathway. These findings provide toxicological and mechanistic information that can help in assessing the effects of nanosilver in biological systems, including the potential for anticancer activities.

Introduction. Honey bee venom (HBV) has various biological activities such as the inhibitory effect on several types of cancer. Cisplatin is an old and potent drug to treat most of the cancers. Our aim in the present study was to determine antimutagenic and cytotoxic effects of HBV on mammary carcinoma, exclusively and in combination with cisplatin. Methods. In this study, 4T1 cell line was cultured in RPMI-1640 with 10% fetal bovine serum (FBS), at 37°C in humidified CO2 incubator. The cell viabilities were examined by the MTT assay. Also, HBV was screened‏ for its antimutagenic activity via the Ames test. The results were assessed by SPSS software version 19 and one-way ANOVA method considering p<0.05 level of significance. Results. The results showed that 6 mg/ml of HBV, 20 μg/ml of cisplatin, and 6 mg/ml HBV with 10 μg/ml cisplatin could induce approximately 50% of 4T1 cell death. The concentration 7 mg/ml of HBV with of 62.76% inhibitory rate showed the highest antimutagenic activity in comparison with other treatment groups. Conclusions. The MTT assay demonstrated that HBV and cisplatin could cause cell death in a dose-dependent manner. The cytotoxic effect of cisplatin also promoted by HBV. Ames test outcomes indicated that HBV could act as a significant mutagenic agent. The antimutagenic activity of HBV was increased considerably in the presence of S9 mix. Therefore, our findings have revealed that HBV can enhance the cytotoxic effect of cisplatin drug and its cancer-preventing effects.

Abstract Multiple myeloma (MM) represents an incurable disease for which development of new therapies is required. Here we report the effect on myeloma cells of AEW541, a new small molecule, belonging to the pyrrolo[2,3-d] pyrimidine class, identified as inhibitor of the IGF-1R in vitro kinase activity. AEW541 showed a potent antimyeloma activity (IC50 <4.5 μM) on MM cell lines both sensitive (MM1S, U266, OPM2, RPMI8226) and resistant (MM1R and U266LR7) to conventional chemotherapeutic agents. In fresh cells from five MM patients a marked antitumor activity was confirmed. AEW541 showed a synergistic effect with dexamethasone and lenalidomide, while it was additive with melphalan and bortezomib. Moreover the triple combination of AEW541, bortezomib and dexamethasone showed even higher anti-MM activity. Gene expression profiles of MM1S cells identified a total of 967 genes to be significantly deregulated (transcriptional changes in gene expression of 2-fold or greater) by treatment with AEW541. The classification of these genes according to functional categories indicated that 3.5% were involved in apoptosis/responses to stress and 13% in the control of cell cycle/proliferation. By Western analyses, we observed that AEW541 affected genes involved in cell cycle and cell death pathways. AEW541 blocked cell cycle progression, and this was accompanied by p27, up-regulation and pRb, CCND1, CCNA and CCNE downregulation. AEW541 induced cell death through an increase in the mitochondrial outer membrane permeability and provoked DNA fragmentation. AEW541 induced apoptosis and at late time points, also activated caspases 8,9 and 3. The pan-caspase inhibitor Z-VAD-FMK only slightly decreased the sensitivity to AEW541. In addition, AEW541 stimulated a caspase-independent pathway, through the release of AIF and Endonuclease G from the mitochondria. It is therefore conceivable that both caspase dependent and independent pathways are activated by AEW541 in MM cells, although the effect of AEW541 on cell cycle arrest is an earlier and more potent event. Finally, AEW541 was able to overcome the protective effect that confers IL-6, IGF-1 and BMSCs to myeloma cells in a dose dependent manner. All these data indicate that AEW541 could be a useful drug for the treatment of MM patients, particularly in combination with other novel agents such as bortezomib or lenalidomide together with dexamethasone.

Abstract Abstract 4824 Recent studies have shown that prostaglandin E2 (PGE2) may play a key role in the tumorigenesis and tumor development. Membrane-bound prostaglandin E2 synthase-1 (mPGES-1), an inducible enzyme that acts downstream of cyclooxygenase (COX) and specifically catalyzes the conversion of prostaglandin H2 (PGH2) to PGE2, was over-expression in a variety of solid tumor cells and tissues such as nonsmall-cell lung cancer, colon carcinoma, gastric carcinoma and breast cancer. MK886, a small molecular inhibitor, is a reasonable potency as an inhibitor of mPGES-1 in vitro experiment. In this study, we examined effects of MK886 on expression of mPGES-1 and PGE2 synthesis in human acute myeloid leukemia cell line (HL-60), observed cell proliferation and apoptosis after 24-h treatment with MK886, and tried to explore the possible mechanisms by checking some protein belong AKT cell singling pathway such as P-AKT, Bax and Bcl-2. We found that the expression levels of mPGES-1 mRNA and protein were higher in HL-60 cells than in normal mononuclearcells (MNC). MK886 inhibited mPGES-1 mRNA and protein expression and reduced PGE2 secretion in HL-60 cells in a dose-dependent manner. The cell proliferation was inhibited and the IC50 was 132.16μmol/L. With the increase of MK886 concentration, the cell apoptosis rate assayed by flow cytometry increased and the apparent apoptotic bodies increased when staining by Hoechst 33258. After treated with MK886 for 24h, protein was extracted and assayed by western blot. The results showed that the expression levels of P-AKT, Bcl-2 and c-myc decreased while the Bax protein expression increased in a dose-dependent manner. The caspase-3 activity, determined by colorimetric detection, also increased dose-dependently. These results indicated that mPGES-1 over-expressed in leukemia cell line HL-60, MK886 could induce apoptosis in HL-60 cells via reducing mPGES-1 expression and PGE2 synthesis dose-dependently, thereby regulate the AKT pathway including Bcl-2 family and the activity of caspase-3. It suggested that mPGES-1 inhibitor might emerge as an important therapeutic tool for leukemia treatment. Disclosures: No relevant conflicts of interest to declare.

Induction Of Apoptosis

Plants with anticancer properties are considered as cancer preventive and treatment sources, due to their some biological effects. Apoptosis induction and anti-proliferative effects of Baneh extract on various cancer cell lines have been reported. Hence, this study was designed to evaluate the cytotoxic effects of this fruit on KB and human gingival fibroblast cell lines (HGF). KB and HGF cells were treated with various concentrations of ethanolic Baneh extract and cisplatin as positive control. Cytotoxic activity and apoptosis induction were investigated using WST-1 and Annexin V assays. Data were analyzed using ANOVA and student’s t-tests. IC50 after 24 and 48 hours treatment were respectively 2.6 and 1 mg/mL for KB cell line, and 1.5 and 1.6 mg/mL for HGF cell. During 48 hours Baneh extract induced apoptosis without significant necrosis, in a time- and dose-dependent manner. The induction of apoptosis in KB cells was significantly higher than HGF. It seems that ethanolic extract of Baneh contains compounds that can suppress KB cell growth through the induction of apoptosis. Within 48 hours, less cytotoxic effects were observed on normal fibroblast cells; therefore, it might be a potential anticancer agent.

Co-chemotherapeutics approaches are increasing in cancer treatment in order mainly to suppress the resistence phenomenon of cancer treatment and to enhance the cytotoxic effect of the main chemotherapeutics agent. Tangeretin has been known to have cytotoxic effect to some cancer cells through some pathways in the cells. To explore the potential effect of tangeretin as co-chemotherapeutics agent this research was subjected to study the cytotoxic effect of tangeretin in combination with 5-Fluoro Uracil (5-FU) on WiDr colon cancer cells covering the modulation of cell cycle and apoptosis induction. Cytotoxic effect was examined by using MTT assay while apoptotis induction was determined by annexin-V flowcytometry. Under MTT assay, tangeretin showed weak cytotoxic activity on the cells. However, tangeretin significantly enhanced the cytotoxic effect of 5-FU on the cells. This co-chemotherapeutics effect likely correlated with cell cycle modulation effect, especially in inducing polyploidy phenomenon as expressed in the flowcytometric graph of the DNA content. This combination also increased apoptosis induction. These result suggest that tangeretin is potential to be developed as co-chemotherapeutic agent for 5-Fu on colon cancer and further molecular mechanism need to be explored.Keywords: Tangeretin, 5-Fluorourasil, WiDr, cell cycle, apoptosis.
