The aim of the present study was to determine cytotoxic activity of crude methanolicextract of Echinophora platyloba on breast cancer MDA-MB-231 cell line. The free radicalscavenging effects of methanolic extract of E. platyloba were tested using DPPH method.Crude methanolic extract exhibited potential antioxidant activity with an IC50 value of 234.28 ±21.63 μg/mL when compared to the standard ...

Background and Aim: Phenolic compounds form an important category of antioxidants that have important biological activities, such as anticancer, antifungal, antibacterial and antiviral effects. In this study, the anticancer effects of Gallic acid and P-Coumaric acid were studied on MDA-MB-231 human breast cancer cell line. Materials and Methods: In this experimental study, human breast cancer ...
The ability of tanshinone IIA (Tan-IIA) to inhibit the proliferation of human breast cancer cell lines in vitro and in vivo is well documented. However, the molecular mechanisms have not been fully elucidated. In the present study, MDA-MB-231 cells were treated with different concentrations of Tan-IIA for 48 h, followed by protein extraction for western blotting. For an in vivo study, MDA-MB-23...
The present work investigates the relationship between cancer cell chemosensitivity and subcellular distribution, molecular interaction, and metabolism of an anticancer drug. To get insights into this relationship, we took advantage of the differential sensitivity of two breast cancer cell lines, MDA-MB-231 and MCF-7, to anthracyclines, along with the property of docosahexaenoic acid (DHA, 22:6...
objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...
To address pivotal roles of cell surface F1/FO ATP synthase in the development of acidic microenvironment in tumor tissues, we investigated effects of shear stress stimulation on the cultured human breast cancer cells, MDA-MB-231 and MDA-MB-157, or human melanoma cells, SK-Mel-1. Shear stress stimulation (0.5-5.0 dyn/cm(2)), the levels of which are similar to those produced by the interstitial ...
Cancer cells secrete VEGF, which plays a key role in their growth, invasion, extravasation and metastasis. Direct cancer cell-endothelial cell interaction, mediated by gap junctions, is of critical importance in the extravasation process. In this study, we evaluated avastin (Av), an anti-VEGF antibody; and oleamide (OL), a gap junction inhibitor, using MDA-MB-231 human breast cancer cells in vi...
Pyruvate carboxylase (PC) is an anaplerotic enzyme that catalyzes the carboxylation of pyruvate to oxaloacetate, which is crucial for replenishing tricarboxylic acid cycle intermediates when they are used for biosynthetic purposes. We examined the expression of PC by immunohistochemistry of paraffin-embedded breast tissue sections of 57 breast cancer patients with different stages of cancer pro...
Dietary phytochemicals are known to exhibit a variety of anticarcinogenic properties. This study investigated the chemopreventive activity of blueberry extract in triple-negative breast cancer cell lines in vitro and in vivo. Blueberry decreased cell proliferation in HCC38, HCC1937, and MDA-MB-231 cells with no effect on the nontumorigenic MCF-10A cell line. Decreased metastatic potential of MD...
