Background: In the current era, development of molecular techniques involves nanotechniques and the synthesis of nanoparticles is considered as the preferred field in nanotechnology. Objective: The aim of the present work is to analyze the anticancer activity of the thymoquinone conjugated ZnO nanoparticles and to understand its mechanism of action in triple negative breast cancer cell line MDA-MB-231. Methods: Zinc Oxide (ZnO) nanoparticles have extensive applications and it was synthesized using a chemical precipitation method. Thymoquinone (TQ) is the major bioactive component of the seeds of Nigella sativa. Synthesized nanoparticles were characterized using various spectroscopic techniques. Thymoquinone coated nanoparticles were checked for its efficiency. The cytotoxicity of ZnO, TQ and TQ conjugated ZnO nanoparticles against MDA-MB-231. Colony forming and cell migration assay were performed to measure the proliferative competence of the breast cancer cells on exposure to nanoparticles. The mechanism of apoptosis was probed by assessing MMP, interplay between ER stress and ROS. Results: The results of the characterization techniques confirmed the particles synthesized were ZnO and TQ-ZnO nanoparticles. pH dependent release of the compound was observed. Anti-proliferative effect that impairs the formation of colony was found to be enhanced in cells exposed to combined treatment with the nanoconjugate. Conclusion: Hence, the TQ conjugated ZnO nanoparticles can act as an efficient carrier for drug delivery at the target site in TNBC cells.

Background: Mummy (Iranian pure shilajit) is a remedy with possessing anti-inflammatory, antioxidant and anticancer activities. This study aimed to examine mummy effects on epithelial-mesenchymal transition (EMT) and invasiveness of MCF-7 and MDA-MB-231 breast cancer (BC) cell lines with underlying its mechanism. Materials and Methods: The dose-dependent inhibitory effect of the mummy on cell proliferation in vitro was determined using the MTT assay.  Flow cytometry and 4’,6-diamidino-2-phenylindole dihydrochloride staining were respectively used for quantitative and qualitative analysis of cellular apoptosis, and gene expression analysis was conducted using real-time PCR. Results: MDA-MB-231 showed more sensitivity than the MCF-7 cell line to the anticancer activity of mummy, while mummy did not exhibit significant cell cytotoxicity against human normal cells (MCF-10A). The gene expression profile demonstrated a significant decrease in TGF-β1, TGF-βR1, TWIST1, NOTCH1, CTNNB1, SRC along with an increase in E-cadherin mRNA levels in mummy treated cells compared to the untreated control group (P≤0.05). Conclusion: Mummy triggers inhibition of EMT and metastasis in breast cancer cells mainly through the downregulation of TGFβ1 activity, and more studies required to find its specific anticancer activity with details.

Background: Medicinal plants have been used in traditional medicine for the treatment of numerous diseases worldwide. There is a dire need for new anticancer agents and plants used in traditional medicine are a particularly useful source. Materials and methods: In this study, extracts of five different plants that grow in the desert of Saudi Arabia were evaluated to assess their cytotoxicity against the MDA-MB-231 breast cancer cell line. Soxhlet extraction was carried out on the leaves and stems using different solvents. The cytotoxicity of these extracts against MDA-MB-231 breast cancer cells was assessed using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays. The apoptotic cellular morphological changes were observed using inverted and fluorescence microscopes. Results: Our results showed that two of the five different medicinal plants (Rumex vesicarius and Malva parviflora) exhibited strong anticancer activity against the breast cancer cells. Specifically, 2 of the 40 extracts (from the five studied plants) showed promising activity. The chloroform extract of the stem of R. vesicarius (RSV CHCL3) exhibited moderate anticancer activity with a half-maximal inhibitory concentration (IC50) of 230 µg/mL while that of the hexane extract of M. parviflora stems (MPS Hex) was 248 µg/mL. Loss of cell integrity, shrinkage of the cytoplasm, and cell detachment were observed in the extract-treated MDA-MB-231 cells. Conclusion: R. vesicarius and M. parviflora chloroform and n-hexane stem extracts showed significant cytotoxicity against MDA-MB-231 human breast carcinoma cells.
