Kefir drink is one of the most important probiotic products, which is made using kefir microorganisms in fermenting the milk. Numerous investigation have been accomplished in the field of the therapeutic property of probiotic products. In the present study, we assessed the cytotoxic effect of kefir on the rate of growth and increase of glioblastoma cancer cell as the most severe form of brain tumors. In this experimental study, we used a U87 cancer cell line (glioblastoma). The interaction between cancer cells and different concentrations of kefir drink and supernatants at 24 and 48 hours was considered. The cell cytotoxicity of kefir and sedimentation of cell lysate and extract of kefir was assessed using the MTT test after 24 and 48 hours. The result of the MTT test, treatment of the cells with the 48-hour fermented drink, demonstrated the most cell cytotoxicity in comparison with the control group. Results showed that the toxicity effect in all groups was dose-dependent, and by increasing the concentration, cell survival decreased noticeably. The results indicated that the supernatant of fermented kefir drink as a probiotic product has more toxicity and lethality effect on the glioblastoma cancer cell. This product can be utilized as a replacement or a complementary therapy of cancer.

Phytochemical study of Chiliadenus montanus aerial parts afforded six compounds; Intermedeol (1), 5α-hydroperoxy-β-eudesmol (2), 5,7-dihydroxy-3,3’,4’-trimethoxyflavone (3), 5,7,4’-trihydroxy-3,6,3’-trimethoxyflavone (jaceidin) (4), eudesm-11,13-ene-1β,4β,7α-triol (5) and 1β,4β,7β,11-tetrahydroxyeudesmane (6). These compounds were identified based on their NMR spectral data. The isolated compounds were tested for their cytotoxicity against liver cancer cell line (HepG2) and breast cancer cell line (MCF-7). Jaceidin flavonoid (4) exhibited the highest cytotoxic effect in vitro. Therefore, both of jaceidin and C. montanus extract were evaluated for their in vivo anti-tumor activity against Ehrlich’s ascites carcinoma (EAC). Compared to control group, jaceidin and C. montanus extract decreased the tumor weight, improved the histological picture of tumor cells, lowered the levels of VEGF and ameliorate the oxidative stress. Molecular docking and in silico studies suggested that jaceidin was a selective inhibitor of VEGF-mediated angiogenesis with excellent membrane permeability and oral bioavailability.

The microRNA-200 (miR-200) family has been reported to be vital for the inhibition of epithelial-to-mesenchymal transition (EMT) in tumor cells. The miR-200 family represents a complex multi-factorial regulatory network which has not been well described in breast cancer. This study aimed to clarify the underlying regulatory association between IL-8 and miR-200 family in the process of EMT in breast cancer cell. In estrogen-receptor (ER) positive breast cancer cell line MCF-7, IL-8 overexpression cells were performed by lentivirus transfection as endogenous regulation with additional exogenous IL-8 stimulation. Transient overexpressions of miR-200 family were performed after endogenous or exogenous IL-8 overexpression in MCF-7 cells. IL-8 knockdown cells were constructed via siRNA and shRNA transfection in triple negative breast cancer cell line MDA-MB-231. N-cadherin, vimentin and ZEB2 were down-regulated and E-cadherin was up-regulated in IL-8 knockdown group compared with control group. On the other hand, N-cadherin, vimentin and ZEB2 were up-regulated and E-cadherin was down-regulated in IL-8 overexpression group compared with control group. This indicated IL-8 promotes EMT in breast cancer cells. Transwell assay showed that IL-8 increased the migration and invasiveness of tumor cells. Furthermore, we performed transient overexpression of miR-200 family after endogenous or exogenous IL-8 overexpression in MCF-7 cells, which showed that the miR-200 family could inhibit EMT induced by IL-8. IL-8 promoted EMT via downregulation of miR-200 family expression in breast cancer cells and increases tumor cell migration and invasion.

Introduction: Anticancer effects of Lactobacillus acidophilus, as a probiotic bacterium, have been indicated in several studies. There are common therapeutic options for bladder cancer treatment; however, their side effects and recurrence of disease are considerable. Therefore, complementary medication is essential and it must be safe and effective. In the present research, we assessed the anti-tumor activity of Lactobacillus acidophilus (LB) on the bladder cancer cell line by evaluating the apoptosis mechanism. Materials and Methods: EJ138 bladder cancer cell line was provided and the cytotoxicity level of LB was evaluated with various concentrations after 24, 48, and 72 h. To evaluate the apoptosis effect, the gene expression of Bax, BCL2, and TNF-α was assessed using real-time PCR. Results: The optimum concentration of the cytotoxicity level was 12.5μg/mL at 24, 48, and 72 h. Bax expression was upregulated in tumor cells treated with LB alone and the mixture of LB and BCG (LB/BCG) as compared to the control group after 24 and 48 h. Also, the mRNA level of TNF-α increased in treated cells with LB and LB/BCG compared to the control group. BCL2 expression did not show a significant difference between experimental groups versus the control group. Conclusion: Our findings showed that LB has a synergistic effect with BCG through increasing apoptotic gene expression and TNF-α cytokine. Besides, at 48 h treatment, the apoptosis effect is more than 24 h. Thus, it seems that the mode of action of LB is time-dependent.

Cancer chemotherapies may result in resistance, and therefore, contemporary treatments including natural products may find an increasing consideration. As per Persian medicine (PM), many natural products have been used for malignant and chronic diseases. Triphala, with a combination of Terminalia chebula Retz., Terminalia bellirica Retz., Phyllanthus emblica L., and honey, is a multi-ingredient traditional formulation attributed to anticancer activities in PM. This study is aimed at evaluating the cytotoxic activity of this preparation on HepG2, the human liver cancer cell line. Hydroalcoholic extracts were prepared from the formulation and its components. Compared with the control and Cisplatin, the extracts were tested using MTT assay at different concentrations. All concentrations of the preparation, as well as Cisplatin, were effective significantly against HepG2 cells. All extract preparations at multiple concentrations were significantly effective as evidenced by MTT assay when compared to the control group. The IC50 level for Triphala extract was 77.63 ± 4.3   μ g / ml . Based on the results, Triphala and its components have cytotoxic activity on the HepG2 cancer cell line and they can reduce the survival rate significantly.

A recombinant deoxyribonucleoside kinase from Drosophila melanogaster with a deletion of the last 20 amino acid residues (named DmdNKΔC20) was hypothesized as a potential therapeutic tool for gene therapy due to its broad substrate specificity and better catalytic efficiency towards nucleosides and nucleoside analogs. This study was designed to evaluate the effect of DmdNKΔC20 for sensitizing human cancer cell lines towards gemcitabine and to further investigate its role in reversal of acquired drug resistance in gemcitabine-resistant cancer cell line. The DmdNKΔC20 gene was delivered to three different cancer cell lines, including breast, colon and liver cancer cells, using lipid-mediated transfection reagent. After transfection, gene expression of DmdNKΔC20 was confirmed by reverse transcription quantitative PCR (qRT-PCR) and the combined effect of DmdNKΔC20 and gemcitabine based cytotoxicity was observed by cell viability assay. We further evolved a gemcitabine-resistant breast cancer cell line (named MCF7-R) through directed evolution in the laboratory, which showed 375-fold more resistance compared to parental MCF7 cells. Upon transfection with DmdNKΔC20 gene, MCF7-R cells showed 83-fold higher sensitivity to gemcitabine compared to the control group of MCF7-R cells. Moreover, we observed 79% higher expression of p21 protein in transfected MCF7-R cells, which may indicate induction of apoptosis. Our findings highlight the importance and therapeutic potential of DmdNKΔC20 in combined gene/chemotherapy approach to target a wide range of cancers, particularly gemcitabine-resistant cancers.

Melastoma Malabathricum

Methanol extract of Melastoma malabathricum (MEMM) has been traditionally used by the Malay to treat various ailments. In an attempt to develop the plant as an herbal product, MEMM was subjected to the subacute and subchronic toxicity and cytotoxicity studies. On the one hand, the subacute study was performed on three groups of male and three groups of female rats (n = 6), which were orally administered with 8% Tween 80 (vehicle control group) or MEMM (500 and 1000 mg/kg) daily for 28 days, respectively. On the other hand, the subchronic study was performed on four groups of rats (n = 6), which were orally administered with 8% Tween 80 (vehicle control group) or MEMM (50, 250, and 500 mg/kg) daily for 90 days, respectively. In the in vitro study, the cytotoxic effect of MEMM against the HT29 colon cancer cell line was assessed using the MTT assay. MEMM was also subjected to the UHPLC-ESI-HRMS analysis. The results demonstrated that MEMM administration did not cause any mortality, irregularity of behaviour, modification in body weight, as well as food and water intake following the subacute and subchronic oral treatment. There were no significant differences observed in haematological parameters between treatment and control groups in both studies, respectively. The in vitro study demonstrated that MEMM exerts a cytotoxic effect against the HT29 colon cancer cell line when observed under the inverted and phase-contrast microscope and confirmed by the acridine orange/propidium iodide (AOPI) staining. The UHPLC-ESI-HRMS analysis of MEMM demonstrated the occurrence of several compounds including quercetin, p-coumaric acid, procyanidin A, and epigallocatechin. In conclusion, M. malabathricum leaves are safe for oral consumption either at the subacute or subchronic levels and possess cytotoxic action against the HT29 colon cancer cells possibly due to the synergistic action of several flavonoid-based compounds.

Purpose: To investigate the anti-proliferative and apoptotic influences of alantolactone on gastric carcinoma (GC) cell lines, and the mechanism(s) involved. Methods: Human gastric cancer cell line (BGC823) and gastric adenocarcinoma lymph node metastasis cell line (SGC7901) were maintained in Ham’s F12 medium supplemented with 10 % heatinactivated fetal bovine serum (FBS). In each group of cancer cell line, 5 groups of cells were used: control and four alantolactone groups which were treated with increasing concentrations of alantolactone (5 - 30 μM) for varying periods. Proliferation was determined using MTT assay, while realtime quantitative polymerase chain reaction (qRT-PCR) was used to assay the expressions of apoptosis- and metastasis-related genes. The expressions of p38MAPK and nuclear transcription factor-κB (NF-κB) in BGC823 and SGC7901 cells were measured with Western blotting. Results: Phosphorylated protein (p-p38 protein) expression was significantly higher in both groups of GC cells, relative to control (p < 0.05). The expressions of NF-κB in plasma protein were markedly higher in both groups of GC cells than in control group, but the corresponding expressions in nuclear protein were significantly lower in both groups of GC cells, relative to control (p < 0.05). Conclusion: Alantolactone exerts anti-proliferative and apoptotic effects on BGC823 and SGC7901 cells via mechanisms involving activation of the p38MAPK, and inhibition of the NF-κB signaling pathways. Thus, alantolactone may be a new and effective anti-gastric cancer drug.

We evaluated the effect and mechanism of yam polysaccharide on the proliferation of the prostatic cancer cell line and tumor-bearing mice. The effect of nanoyam polysaccharide on prostatic cancer cell line PC-3 was measured using the scratch adhesion test and flow cytometry. The growth effect induced by nanoyam polysaccharide was detected with the CCK-8 test. The levels of caspase-3 protein were determined with Western blot. In our data, nanoyam polysaccharide presented inhibitory effect on the proliferation of PC-3. The scratch adhesion test showed that the rate of wound healing in the intervention group was significantly lower than that in the control group (p<0.05). Flow cytometry assay showed that, after treatment with nanoyam polysaccharide, the apoptosis rate in the intervention group was significantly lower than that in the control group (45.8%±2.6%, 25.8%±3.1%; p<0.05). Western blot assay showed upregulated levels of caspase-3 in the intervention group, compared to the control group (p<0.05). Our results suggested that nanoyam polysaccharide strongly suppressed the growth of prostatic cancer by inducing the overexpression of caspase-3 and may be a potent anticancer strategy.

Abstract Purpose: Breast cancer is one of the most common cancer among. Chemotherapy and radiation along with surgery are common methods for treating cancer, but they exhibit side effects on normal cells in the body. We used peptides, as new anti-cancer agents, seem to have fewer reactions on the body's natural cells and are specialized markers for targeting cancer cells. Materials and methods: Metabolomics data are obtained by 1HNMR, LC/MS and GC/MS spectrometry and analyzed by chemometrics techniques and the affected metabolic cycles identified using different databases. ZR-75-1 cells were collected with estradiol (positive control), without estradiol (negative control) and estradiol with peptide (treatment group) and the metabolites of these 3 groups were collected by chloroform/methanol or water extraction method. Spectra were analyzed by 1HNMR and chemometric methods using PLS-DA techniques by which differentiating chemical shifts and their respective metabolites were identified using the Human Metabolome Database. The differentiating metabolic pathways were detected using Metaboanalyst.ca website. Results: A concentration of 10-9 M estradiol induced the growth of estradiol-dependent ZR-75-1 cells compared to the control group. A concentration of 10-10 M MH-I peptide inhibited the growth of estradiol-induced growth in this ER + breast cancer cell line. Altered metabolites and metabolic pathway were distinguished. Conclusion: Changes were observed in different amino acids and carbohydrates. The pathways of aminoacyl-t-RNA, glycolysis. Gluconeogenesis and biosynthesis of biotin and amino acids showed the most changes. The results from this study introduces a new peptide drug lead for the treatment of breast cancer with estrogen positive receptor.
