The Effect of Herbal Medicine on Colon Cancer Cells in Culture

Medicinal herbs are being increasingly recognized as useful complementary treatments for cancer. Colon cancer is the third most common cancer in men and the second in women worldwide. Colon cancer diseases is very heterogeneous in terms of grade, genetics, ploidy, and oncogene/tumor suppress or gene expression and its biological, hormonal, and molecular characteristics are extremely complex. In this study our aim was to identify the effect of different medical plants Viscum album, Inula viscosa, Hypericum perforatum, Lysimachia nummularia, Oleocanthal, Pinus pinaster and Rubus caeisus on colon cancer cell line. Colo320 cancer cells and human adipose tissue derived mesenchymal stem cell were analysed for four medical plants in culture. Firstly, the cytotoxicity rate (IC50) determined by MTT. After that, immunocytochemical staining were done eNOS, VEGF and TUNEL method for apoptosis. The stainings were evaluated by H-score. As a result, Inula viscosa and Rubus caeisus have a higher inhibitory effect on cell proliferation and apoptosis in both cancers than the other medicinal plants. Colo320 cancer cells expressed strong eNOS by these plants and also both plants were not toxic for adipose tissue derived mesenchymal stem cells

The Effect of Herbal Medicine on Prostate Cancer Cells in Culture

Herbal medicine has been used historically for anticancer effect and potent antiproliferative effects on different cancer cell lines. Prostate cancer has become the most common malignancy and the second highest cause of cancer death Western world. The antioxidant, antidepressant and antimicrobial effect of Viscum album, Inula viscosa, Hypericum perforatum, Lysimachia nummularia, Oleocanthal, Pinus pinaster and Rubus caeisus on cancer cell lines. In this study, we investigated whether these seven plants show any anticancer properties on prostat cancer cell line. Du145 cancer cells and human adipose tissue derived mesenchymal stem cell were assessed for seven medical plants in culture with different doses. Firstly, the cytotoxicity rate (IC50) determined by MTT and then immunocytochemical procedure were done for oxidative stress (eNOS), angiogenesis (VEGF) and TUNEL method for apoptosis. The stainings were evaluated by H-score. According to the results, Inula viscosa and Rubus caeisus have a higher improvement effect than the other medicinal plants. And these plants were not toxic for adipose tissue derived mesenchymal stem cells. These plants caused the inhibition of cell proliferation and apoptosis in prostat cancer cells. Our results indicated that these plants may be potential agents in prostat cancer treatment

Effects of stem cells applications on oxidative stress and apoptosis during implantation

Objective: To investigate the effects of bone marrow derived mesenchymal stem cell (BMSC) application into the rat endometrium on oxidative stress, cell proliferation and apoptosis. Methods: The female rats selected in estrous cycle were divided into three groups (saline, media and BMSC group). The intrauterine and intraperitoneal injections were performed using the saline (200 μL), culture media (200 μL) and 1×106 BMSCs/200 μL culture media, and then they were mated with male rats. On the 7th day of the pregnancy, uterine samples were harvested and dyed with heamatoxylin-eosin histochemically, anti-endothelial nitric oxide synthase and anti-inducible nitric oxide synthase, and anti-proliferating cell nuclear antigen immunohistochemically, with terminal deoxynucleotidyl transferas dUTP nick end labeling for apoptosis. The stainings were evaluated by H-score and the results were analyzed using one-way ANOVA test statistically. Results: It was found that BMSCs increased the endometrial thickness, endometrial epithelium thickness and number of endometrial glands compared to control and sham groups. The intrauterine BMSC application decreased both anti-endothelial nitric oxide synthase and anti-inducible nitric oxide synthase immunoreactivities and the number of apoptotic cells compared to the intraperitoneal applications whereas the immunoreactivity of proliferating cell nuclear antigen was increased. Conclusions: In current study, we define that stem cells do not cause any structural damages. Also they change the distribution of oxidative stress and cell proliferation marker. These findings support the reliability of stem cells in clinical use in the case of infertility

Antiproliferative and Apoptotic Effects of the Medicinal Plants on Breast Cancer Cell Lines

Inula viscosa, Rubus caesius and Viscum album known as medicinal plants which have therapeutic properties in treatment of various diseases and particularly cancer. In this study, we aimed to show their anti-proliferative and apoptotic effects on MCF-7, MDA-MB-231, 67NR and 4T1 breast cancer cell lines. The cell lines were cultured to determine the cell growth using the MTT assay. Cells were cultured to evaluate for eNOS, VEGF and apoptosis by immunocytochemical staining and TUNEL assay. Statistical analysis was performed with the H-score. Inula viscosa, Rubus caesius and Viscum album extracts were found to significantly inhibit the growth of breast cancer cell lines in dose and time-dependent manner. eNOS staining was significantly increased and VEGF was decreased after extract application at IC50 dose. Similarly, results indicated that the treated breast cancer cell lines exhibited a marked increase in apoptosis. We showed that the toxic effect of Inula viscosa, Rubus caesius and Viscum album extracts created by oxidative stress and apoptotic mechanisms. Our findings suggested that due to their anticancer potential, these plants may be used as an alternative treatment for the management of cancer. Therefore future studies will focus on the identification of the molecules responsible for the anticancer activity
