Cell migration plays a central role in the invasion and metastasis of tumors. As cells leave the primary tumor, they undergo an epithelial to mesenchymal transition (EMT) and migrate as single cells. Epithelial tumor cells may also migrate in a highly directional manner as a collective group in some settings. We previously discovered that myoferlin (MYOF) is overexpressed in breast cancer cells...
Telomeres are repetitive (TTAGGG)(n) DNA sequences found at the end of chromosomes that protect the ends from recombination, end to end fusions, and recognition as damaged DNA. Telomerase activity can be detected in 85% to 90% of human tumors, which stabilizes telomeres to prevent apoptosis or cellular senescence. Previous reports showed the efficacy of the novel telomerase template antagonist,...
Background: Plants are an important natural source of compounds used in cancer therapy. Pancratium maritimum contains potential anti-cancer agents such as alkaloids. In this study, we investigated the anti-proliferative effects of P. maritimum extracts on MDA-MB-231 human epithelial adenocarcinoma cell line and on normal lymphocytes in vitro. Methods: Leaves, flowers, roots, and bulbs of P. mar...
Supplementary Figure 1. Total number of MDA-MB-231 cells is conserved in four micropattern design. (a): Green fluorescence protein expression measured by plate reader after cell lysis served as an accurate measure of cell number in the culture. (b): MDA-MB-231 cells harvested from four micropatterns had similar amount of cells, with none of the groups having statistical difference from the othe...
Parvin-beta is a focal adhesion protein downregulated in human breast cancer cells. Loss of Parvin-beta contributes to increased integrin-linked kinase activity, cell-matrix adhesion, and invasion through the extracellular matrix in vitro. The effect of ectopic Parvin-beta expression on the transcriptional profile of MDA-MB-231 breast cancer cells, which normally do not express Parvin-beta, was...
Cell migration is considered necessary for the invasion that accompanies the directional formation of the cellular protrusions termed lamellipodia. In invasive breast cancer MDA-MB-231 cells, lamellipodia formation is preceded by translocation of the actin cytoskeletal regulatory protein WAVE2 to the leading edge. WAVE2 translocation and lamellipodia formation require many signaling molecules, ...
Breast cancer is one of the most common malignancies diagnosed in women and it is increasing in incidence. Siegesbeckia glabrescens (SG) has been used in traditional oriental medicine to treat cardiovascular diseases such as hypertension and angina pectoris. This study examined whether or not SG could induce apoptosis in human breast carcinoma cells. The treatment of estrogen-receptor (ER)-posi...
Vasculogenic mimicry (VM) refers to the unique capability of aggressive tumor cells to mimic the pattern of embryonic vasculogenic networks. Claudins are aberrantly expressed in aggressive breast cancer. However, the relationship between claudins and VM formation is not clear. We examined VM in two human breast cancer cell lines with different aggressive capabilities (MDA-MB-231 and MCF-7 cells...
The matrix metalloproteinases (MMPs) are a family of proteolytic enzymes that degrade multiple components the extracellular matrix. significant role MMPs in tumor invasion, neoangiogenesis and metastasis presented it as ideal pharmacological targets for cancer therapy. effects ursolic acid (UA) on metalloproteinase (MMP) gene expression, cell invasion migration were investigated MDA MB- 231 lin...
Background: Despite modern developments in its management, still major concerns remain about drug resistance in chemotherapy. Natural adjuvants combined with chemotherapy might be the answer. We examined the anti-cancer, anti-proliferative and synergistic effects of Sambucus nigra extract with cisplatin chemotherapy (CDDP) on MCF-7 and MDA-MB-231 human cancer cell lines. Methods: MCF-7 and MDA...
