Objective (s): In chemotherapy for cancer treatment, the cell resistance to multiple anticancer drugs is the major clinical problem. In the present study, mesoporous silica nanoparticles (MSNs) were used as a carrier for epirubicin (EPI) in order to improve the cytotoxic efficacy of this drug against the P-glycoprotein (P-gp) overexpressing cell line. Materials and Methods: MSNs with phosphonat...

objectives: 7-prenyloxycoumarins are a group of secondary metabolites that are found mainly in plants belonging to the rutaceae and umbelliferae families. this study was designed to evaluate and compare the cytotoxic and apoptotic activity of 7-prenyloxycoumarin compounds and herniarin on mcf-7, a breast carcinoma cell line. materials and methods: cells were cultured in rpmi medium and incubate...

      ICD-85 (venom derived peptides) has anti-proliferative effect and anti-angiogenesis activity on cancer cells. This study was performed to test the effect of ICD-85, on Human breast adenocarcinoma (MCF-7) and normal Human Dermal Fibroblasts (HDF) cell lines. In this experimental study, Mitochondrial activity, Neutral red uptake, Lactate dehydrogenase (cell necrosis), and cell morphology we...

Objective- The studies have been shown that aspirin, an anti-inflammatory agent, could reduce occurrence of different cancers. The aim of the present study was to evaluate pharmacological effective concentrations of aspirin with/without radiotherapy on growth rate of MCF-7 breast cancer cell line Design- Experimental Study Animals- The MCF-7 breast cancer cell line from rats P...

background: norepinephrine plays a trophic role in the control of cell replication and differentiation in target cells that express adrenergic receptors. methods: in this study, we have tested the influence of infraphysiological, physiological and supraphysiological concentrations (0.0001 nm, 1 nm, 10000 nm) of human norepinephrine on the proliferation of breast cancer cells (human breast adeno...

breast cancer is the second main cause of death among women. the use of medicinal plants has been common in many countries since ancient times. the aim of this study was to evaluate the antioxidant and anti-proliferative potential of achillea millefolium l. the antioxidant activity of the aqueous and hydroalcoholic extracts of achillea millefolium l. leaf and flower was measured by dpph and fra...

In vitro studies on cancer cell lines still constitutes a major part of cancer research. It is very important that the researchers consider the importance of basic conditions of working with different cell lines. To the best of authors knowledge, this study is the first one to report the effect of seeding density on the growth curve of three human cancer cell lines. These cell lines include hum...

Cancer is a major cause of death worldwide and causes serious problems in human life. It is developed by uncontrolled growth of a cell or a group of cells. There are many difficulties in treatment of cancer and many researchers are involved in investigating for effective drugs to treat the disease. Caryophyllaceae is a large family of about 86 genera and 2200 herbaceous or subshrub species. The...

Tamoxifen (TAM) resistance has become a severe problem for endocrine therapy of breast cancer. The present study investigated the association between microRNA (miRNA) expression and TAM resistance in breast cancer. The TAM-resistant breast cancer MCF-7C and MCF-7T cell lines were established using the human breast cancer cell line MCF-7 as the parental cell line and 4-hydroxytamoxifen (OHT) as ...

Background: Molecular targeted therapy by different cell death inducers are recently considered in cancer therapy. The aim of this study was to compare the effect of cisplatin and inositol trisphosphate kinase inhibitor (caffeine) on human breast cancer cell line (MCF-7). The pattern of cell death in MCF-7 cells following the exposure to cisplatin and caffeine in individual and combination form...
