Cetuximab resistance is the main obstacle for treatment of EGFR overexpression cancer, including triple-negative breast cancer (TNBC). MicroRNA (miRNA)-155-5p upregulated in TNBC cells; thus, present study explored whether downregulation miR-155-5p enhanced anti-tumor effect cetuximab cells. MDA-MB-231 and MDA-MB-468 cells were infected with lentivirus-epidermal growth factor receptor (EGFR) 72...

PURPOSE To gain new insights into the relationship between angiogenic factors in breast cancer and their effect on extracellular matrix (ECM) remodeling and metastasis, we characterized and validated the "metastatic signature" of human breast cancer cell lines engineered to overexpress VEGF in terms of in vivo MRI-derived angiogenesis and ECM transport parameters. METHODOLOGY MRI was used to ...

Benzyl isothiocyanate (BITC), a constituent of edible cruciferous vegetables, inhibits growth of breast cancer cells but the mechanisms underlying growth inhibitory effect of BITC are not fully understood. Here, we demonstrate that BITC treatment causes FoxO1-mediated autophagic death in cultured human breast cancer cells. The BITC-treated breast cancer cells (MDA-MB-231, MCF-7, MDA-MB-468, BT-...

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...

Improved prognosis for triple-negative breast cancer (TNBC) has plateaued and the development of novel therapeutic strategies is required. This study aimed to explore anti-tumor effect combined eribulin HDAC inhibitor (vorinostat: VOR, pan-HDAC ricolinostat: RICO, selective HDAC6 inhibitor) treatment TNBC. The in combination with an was tested three TNBC cell lines (MDA-MB-231, Hs578T, MDA-MB-1...

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...

Radiotherapy is one of the main options to cure and control breast cancer. The aim this study was investigate sensitivity two human cancer cell lines, MCF7 MDA-MD-231, radiation exposure at timepoints 4 h 24 after radiation. MDA-MD-231 were irradiated with different doses using a Gilardoni CHF 320 G X-ray generator (Mandello del Lario, Italy) 250 kVp, 15 mA [with half-value layer (HVL) = 1.6 mm...

background: ß-carbolines, harmaline and harmine, are the major alkaloids presenting in the seeds of the peganum harmala l. these alkaloids are known as herbal active principals with potential use in pharmaceutical and medicine. objectives: to assess the growth inhibitory effect of phyto-alkaloids, harmaline and harmine, on cancer cell lines. methods: the p. harmala l.’s alkaloids were extracted...

The antiestrogen toremifene has been used to study the growth control of hormone-dependent (MCF-7), -independent (MDA-MB-231), or mixed tumor cell populations in athymic mice. Maximal MCF-7 tumor growth was produced in ovariectomized athymic mice by circulating estradiol levels of approximately 200 pg/ml (produced by 0.5-cm silastic capsules implanted s.c.). The antiestrogen toremifene (77 +/- ...
