Mesenchymal stem cells (MSCs) have been shown to suppress tumor growth, inhibit angiogenesis, regulate cellular signaling, and induce apoptosis in cancer cells. We have earlier reported that placenta-derived decidua parietalis mesenchymal stem/stromal cells (DPMSCs) not only retained their functional characteristics in the cancer microenvironment but also exhibited increased expression of anti-apoptotic genes, demonstrating their anti-tumor properties in the tumor setting. In this study, we have further evaluated the effects of DPMSCs on the functional outcome of human breast cancer cell line MDA231. MDA231 cells were exposed to DPMSCs, and their biological functions, including adhesion, proliferation, migration, and invasion, were evaluated. In addition, genomic and proteomic modifications of the MDA231 cell line, in response to the DPMSCs, were also evaluated. MDA231 cells exhibited a significant reduction in proliferation, migration, and invasion potential after their treatment with DPMSCs. Furthermore, DPMSC treatment diminished the angiogenic potential of MDA231 cells. DPMSC treatment modulated the expression of various pro-apoptotic as well as oncogenes in MDA231 cells. The properties of DPMSCs to inhibit the invasive characteristics of MDA231 cells demonstrate that they may be a useful candidate in a stem-cell-based therapy against cancer.

BACKGROUND Adenocarcinomas can be of several types, and MCF-7 is an adenocarcinoma of human breast cell line useful as preclinical model to screen therapeutic agents such as ultra-diluted Viscum album, an European plant whose extract is commonly used in cancer therapy. AIMS MCF-7 and mesenchymal stem cells were used to evaluate the in vitro cytotoxicity of homoeopathic Viscum album 1x10-3 (VAD3). METHODS cells were cultured for 24 hours in controlled environment (37.5oC and 5% CO2) in 96-well plates. After this time, VAD3 was added to the culture medium in concentrations varying from 10 to 100 ?L/mL for MTT assay (evaluation of viability of cells). A control group was maintained with culture medium only. After 48 hours, the procedures of analysis of cells viability were performed. RESULTS MTT assay showed that the concentrations of 42 ?L/mL and 62 ?L/mL were able to reduce cell viability to 50% in MCF-7 and mesenchymal stem cells, respectively, which means that half of the cells cultured were dead after 48 hours in contact with VAD3. CONCLUSION Viscum album presented higher cytotoxic action on human breast cancer cell line culture than on mesenchymal stem cells. This medicine is extensively used against cancer, and the use of the homoeopathic form of it brings new possibilities as no or fewer adverse effects would be present.

AbstractA series of new 2-phenyl-7-methyl-1,8-naphthyridine derivatives with variable substituents at C3 were synthesized for an in vitro evaluation of their anticancer activity against human breast cancer cell line (MCF7). On one hand, compounds 3f, 6f, 8c, and 10b showed IC50 values (6.53, 7.88, 7.89, 7.79 μM, respectively) compared to that of the mentioned drug staurosparine (IC50 = 4.51 μM). On the other hand, derivatives 10c, 8d, 4d, 10f and 8b displayed better activity than staurosporin with IC50 values (1.47, 1.62, 1.68, 2.30, 3.19 μM, respectively).

Secreted mucins are large O-glycosylated proteins that participate in the protection/defence of underlying mucosae in normal adults. Alteration of their expression is a hallmark of numerous epithelial cancers and has often been correlated to bad prognosis of the tumour. The secreted mucin MUC5B is overexpressed in certain subtypes of gastric and intestinal cancers, but the consequences of this altered expression on the cancer cell behaviour are not known. To investigate the role of MUC5B in carcinogenesis, its expression was knocked-down in the human gastric cancer cell line KATO-III and in the colonic cancer cell line LS174T by using transient and stable approaches. Consequences of MUC5B knocking-down on cancer cells were studied with respect to in vitro proliferation, migration and invasion, and in vivo on tumour growth using a mouse subcutaneous xenograft model. Western blotting, luciferase assay and qRT–PCR were used to identify proteins and signalling pathways involved. In vitro MUC5B down-regulation leads to a decrease in proliferation, migration and invasion properties in both cell lines. Molecular mechanisms involved the alteration of β-catenin expression, localization and activity and decreased expression of several of its target genes. In vivo xenografts of MUC5B-deficient cells induced a decrease in tumour growth when compared with MUC5B-expressing Mock cells. Altogether, the present study shows that down-regulation of MUC5B profoundly alters proliferation, migration and invasion of human gastrointestinal cancer cells and that these alterations may be, in part, mediated by the Wnt/β-catenin pathway emphasizing the potential of MUC5B as an actor of gastrointestinal carcinogenesis.

Abstract As a member of the tight junction family, CLDN6 is a tumor suppressor gene in breast cancer, but its role in colon cancer is unknown. In this research, we aimed at revealing the function of CLDN6 in colon cancer. We found that CLDN6 expressed lower in colon cancer tissues compared with adjacent normal tissues and the low expression of CLDN6 was correlated with lymph node metastasis. Similarly, CLDN6 expressed lower in the colon cancer cell line SW1116 compared with the normal human colon epithelial cell line NCM460. Upon CLDN6 overexpression in SW1116 cells, the proliferation of cells was suppressed in vitro and in vivo. Consistently, the migration and invasion abilities of cells were significantly inhibited after CLDN6 overexpression. Furthermore, the TYK2/STAT3 pathway was activated in SW1116/CLDN6 cells, and inhibition of this pathway with AG490 reversed the inhibition of migration and invasion of SW1116 cells by CLDN6. Therefore, our data indicated that CLDN6 acted as a tumor suppressor and had the potential to be regarded as a biomarker for the progression of colon cancer.
