objective: the objective of this study was to investigate inhibition and anti-cancer effects of linoleic acid on the mcf-7 and mda-mb-231 human breast cancer cells. materials and methods: cell lines human breast cancer mcf-7 (gdc055) and mda-mb-231 (htb-26) cell lines were obtained from atcc. mcf-7 estrogen receptor positive human breast cancer cell line and  the estrogen receptor negative huma...

background cancer stem cells play crucial roles in resistance to therapeutic schemes and relapse of disease, so it is important to find targeted therapies that kill them selectively. breast cancer is the most common cancer in females living in all part of the world including iran and it has an important burden in public health with direct impact on patients’ families. breast cancer in young adu...

objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...

background breast cancer is the most common malignancy in women around the world so finding new biomarkers for early detection and also study on molecular aspects of breast cancer is valuable. cancer testis genes are a group of genes expressed solely in testis and in a range of human malignancies. objectives in this study we determined the expression of cancer testis genes tsga10, tex101 and od...

psa is a 33-kda serine protease that is produced predominantly by prostate epithelium. however, it has been shown that about 30-40% of female breast tumors produce psa and its production is associated with the presence of estrogen and progesterone receptors. we have now developed a new tissue culture system to study psa production in breast cancer and its association with prognostic factors suc...

objective(s): berberine is one of the main alkaloids and it has been proven to have different pharmacological effects including inhibition of cell cycle and progression of apoptosis in various cancerous cells; however, its effects on cancer metastasis are not well known. cancer cells obtain the ability to change their chemokine system and convert into metastatic cells. in this study, we examine...

objective(s):berberine, a naturally occurring isoquinoline alkaloid, has shown antitumor properties in some in vitro systems. but the effect of berberine on breast cancer has not yet been completely studied. in this study, we evaluated anticancer properties of berberine in comparison to doxorubicin. materials and methods: the antiproliferative effects of berberine and doxorubicin alone and in c...

objective: cd44+/cd24-/low breast cancer cells have tumour-initiating properties with stem cell-like features. breast cancer gene 1 (brca1) is a tumour suppressor gene that plays a crucial role in dna repair and maintenance of chromosome stability. the clinicopathological features of breast cancer in brca1 mutation carriers suggest that brca1 may function as a stem-cell regulator. materials and...
