abstract background: the aims of this study were to assay the activity of adenosine deaminase (ada) in estrogen receptor positive (mcf-7) and negative (mda-mb468) breast cancer cell lines. methods: mda-mb468 and mcf-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-lm diethylstilbestrol (des), complete medium in the presence and absence of 111m t...
Tripple negative breast cancer (TNBC) accounts for approximately 15% of breast cancers. It is defined by the absence of estrogen receptor (ER), progesterone receptor (PR), and HER-2 Over expression. Expression of ER, PR and HER-2 plays an important role in therapeutic assessment of patients with breast cancer. TNBC is not one disease, but a family of diseases, some of which are highly aggressiv...
introduction: of the factors leading to false negative results in mammography is breast tissue density, and by increasing the density of breast tissue in mammography, the mammography sensitivity decreases. on the other hand, increasing the breast tissue density leads to increased risk of breast cancer. various factors such as inheritance, genetics, hormonal and reproductive factors, and nutriti...
background: breast cancer is the most common cause of cancer-related deaths among women worldwide. each year it is newly diagnosed in more than 1.1 million women around the world. the aims of this study were to investigate the role of dietary factors such as consumption of vegetables, fruits, dairy products, fried food, fish, and salt along with food, and factors such as weight, physical activi...
background: it seems adipocytokines play an important role in breast cancer. omentin-1 is a novel discovered plasma adipocytokine produced mainly in visceral adipose tissue. the aim of present study was to estimate. circulating levels of omentin-1 in postmenopausal breast cancer patients as compare to healthy postmenopausal subjects. materials and methods: this study consisted of 30 postmenopau...
PURPOSE Currently, there are no definite biomarkers of triple-negative breast cancer. The study aims to identify the metastasis-associated proteins of triple-negative breast tumors. EXPERIMENTAL DESIGN A murine metastatic breast cancer model has been established by using TA2 mice. Parallel proteomic analyses were done on a murine metastatic breast cancer model and its primary breast cancer us...
Common variants in 94 loci have been associated with breast cancer including 15 loci with genome-wide significant associations (P<5 × 10(-8)) with oestrogen receptor (ER)-negative breast cancer and BRCA1-associated breast cancer risk. In this study, to identify new ER-negative susceptibility loci, we performed a meta-analysis of 11 genome-wide association studies (GWAS) consisting of 4,939 ER-n...
Introduction: Breast cancer is one of the most common types of cancer in women with an increasing outbreak. The present study aimed to investigate the relationship between defensive styles and Islamic quality of life (QoL) with death obsession in women with breast cancer. Methods: This research was a correlational study. The statistical population of the study included 220 female patients with...
