Exogenous sphingosine-1-phosphate (SPP) inhibits chemotactic motility of several transformed cell lines. We have found that SPP at high micromolar concentrations decreased chemotaxis of estrogen-independent (MDA-MB-231 and BT 549) and estrogen-dependent (MCF-7 and ZR75-1) human breast cancer cells. Because SPP has been implicated as a lipid-signaling molecule with novel dual intraand intercellu...
Background: A growing body of literature has revealed the effective role of miR-34a, as a tumor suppressor and regulator of expression of multiple targets in tumorigenesis and cancer progression. This study aimed at evaluating the potential effects of miR-34a alone or in combination with paclitaxel on breast cancer cells. Methods: After miR-34a transduction by lentiviral vectors in two MCF-7 an...
Regulation of actin organization and dynamics is a highly complex process that involves a number of actin-binding proteins, including capping, branching, severing, sequestering, and cross-linking proteins. The actin-binding and cross-linking protein AFAP-110 is expressed in normal myoepithelial cells. Screening of different breast epithelial cell lines revealed high expression levels of AFAP-11...
Although drug resistance is often observed in metastatic recurrence of breast cancer, little is known about the intrinsic drug resistance in such metastases. In the present study, we found, for the first time, that MDA-MB-231BR, a brain metastatic variant of a human breast cancer cell line, was refractory to treatment with 5-fluorouracil (5-FU) even without chronic drug exposure, compared to it...
BACKGROUND Tissue factor (TF), an initiator of blood coagulation, participates in cancer progression and metastasis. We recently found that inhibition of MAPK/ERK upregulated both full length TF (flTF) and soluble isoform TF (asTF) gene expression and cell-associated TF activity in breast cancer MDA-MB-231 cells. We explored the possible mechanisms, especially the possible interaction with EGFR...
Methods. Cells and reagents We purchased MDA-MB-231 cells from ATCC and primary IMR90, HDF and primary HUVEC cells from Lonza. MDA-MB-231, IMR-90, HDF and LLC cells were cultured in Eagle’s minimal Essential medium (MEM) from Lonza supplemented with 10% fetal bovine serum (FBS) and 1% GlutaMax (both from Invitrogen). Primary HUVEC cells were cultured in endothelial growth medium (EGM-2, Lonza)....
background: flavonoids have a variety of biological activities, such as anti-allergic, anti-inflammatory, anti-oxidative, free radical scavenging, and anti-mutagenic. methods: the cytotoxic effects of three synthesized flavonoid derivatives (k3, k4 and k5) were evaluated against hela , mda-mb -231 and ht-29 cancer cells using mtt assay. results: the results showed that these flavonoids were not...
Cold atmospheric plasma (CAP) has received great attention due to its noteworthy ability, and has also been widely studied over few decades in physics, biology and medicine. The purpose of this study is to evaluate the cold atmospheric pressure plasma effects on the proliferation of breast cancer cells. MDA-MB-231 was used for this experiment. MDA-MB-231 cells were cultured in 24-well plate and...
The data here is related to the article, "Curcumin enhances poly (ADP-ribose) polymerase inhibitor sensitivity to chemotherapy in breast cancer cells" (Y.E Choi, and E. Park, 2015) [1]. The article shows that curcumin, as a natural bioactive compound, enhanced DNA damage response and induced cell death in MDA-MB-231 cells [1]. This data includes that breast cancer cells, MDA-MB-231 respond to D...
Objective(s): The growing trend of research demonstrates that dynamic expression of two metastasis repressor classes (metastasis suppressor genes and anti-metastatic miRNA) has a close relationship with tumor invasion and metastasis. Using different strategies, it was revealed that cellular levels of miR-31 and Breast cancer Metastasis Suppressor1 (BRMS1) protein, whic...
