objective: estrogen receptor alpha protein status is determined by routine immunohistochemistry analysis in all malignant breast tumors. this assay has its limitations. rna based techniques are potential complements for immunohistochemistry but it must be noticed that gene silencing may occur at different levels from rna to protein. the aim of this study was the comparison of the results from t...

Background: Breast cancer is the most common cancer in women, containing approximately one third of all illnesses in women. Assessment of molecular markers is valuable in predicting the outcome of disease and decision making for optimal treatment. The purpose of this study was to determine the relationship between estrogen and progesterone receptors with Her-2, Ki67, P53, and clinicopathologica...

Triple negative breast cancer (TNBC): challenges and solutions via the immune cells TNBC is one of the most complicated types of breast cancer to treat. It is generally diagnosed based on the absence of three receptors: estrogen, progesterone, and human epidermal growth factor receptor 2 (HER2) and is thus defined as a triple negative. TNBC is often more aggressive with lower survival rates...

Introduction: The G-protein coupled receptor 30 (GPR30) gene is a member of the G-protein coupled receptor (GPCR) family; involved in breast, endometrial, and ovarian cancers. Many GPCR receptors that are implicated in several types of human cancers are correlated with increased cell proliferation and tumor progression; especially GPR30 gene. Methods: The breast cancer MCF-7 and MDA-MB-231 cel...

Objective(s):Leptin receptor (LEPR) is a member of the class I cytokine receptor super-family that is known implicated in the initiation and progression of breast cancer. We have investigated the effect of Q223R polymorphism on the breast cancer susceptibly in a sample of Iranian subjects. Materials and Methods:We utilized a polymerase chain reaction (PCR) restriction fragment length polymorphi...

objective: the incidence of breast cancer is approximately one million which makes this cancer one of the most common among women worldwide. breast cancer comprises 7% of the total death rate caused by cancers. several strategies that use tumor-associated antigen (taa) vaccination and early detection of breast cancer are clinically being developed. breast cancer is caused by increased over expr...

background: breast cancer is the most common cancer in women worldwide. recently, natural remedies such as naringenin (nar) - a kind of flavonoids which can be found in grapefruits, oranges, and tomatoes - seem to be interesting. they play a useful role in treatment and chemoprevention because of having pleiotropic molecular mechanisms of action on breast cancer cells. methods: we performed a p...

Introduction: A main choice for cancer treatment is radiotherapy. But, the radiotherapy disadvantage is damages caused by radiation given to normal tissues/organs surrounding cancer. One way to avoid this is via increasing radiosensitization of cancer cells. Gold nanoparticles (GNPs) have shown sensitizing effect on cancer cells by enhancing their absorbed dose. Unlike earlier ...
