introduction: lower level of estrogen hormone is considered as an important factor for loss of learning and memory in postmenopausal women. although estrogen replacement therapy is used for compensation, but long-term usage of estrogen is associated with a higher risk of hormonedependent cancers. phytoestrogens, due to fewer side effects, have been proposed to prevent menopause-related cognitiv...
PURPOSE Obesity is a risk factor for breast cancer development in postmenopausal women and correlates with shorter disease-free and overall survival in breast cancer patients, regardless of menopausal status. Adipose tissue is a major source of leptin, a cytokine regulating energy balance and controlling different processes in peripheral tissues, including breast cancer cell growth. Here, we in...
Three monoclonal antibodies--H59, H71, and H72--which react with human breast cancers have been developed using the estrogen-dependent human breast cancer cell line, ZR-75-1, as the immunogen. H59 bound only to estrogen receptor-positive, estrogen-regulated breast cancer cells in culture, whereas H71 and H72 bound breast cancer cells irrespective of the estrogen receptor content. All three anti...
Abstract Introduction: Estrogen receptor-positive (ER-positive) breast cancer is a subgroup of breast tumors that is more likely to respond to hormone therapy. ER-positive and ER- negative breast cancers tend to show different patterns of metastasis because of different signaling cascade and genes that are activated by estrogen response. Genetic factors can contribute to high rates of metastas...

Ovarian cancer (OC) is associated with a dismal prognosis and lack of curative treatment. Increased understanding OC biology has led to the development several targeted therapies, including antiangiogenic agents poly(ADP-ribose) polymerase (PARP) inhibitors. Cell cycle inhibitors endocrine therapy such as selective estrogen receptor down regulators are currently under development. In this artic...
Breast cancer is the most common cancer in women worldwide. Current cancer treatments have multiple side effects, including damage to healthy cells, drug resistance and disease recurrence. Therefore, new therapeutic strategies are needed to achieve fewer toxicity and side effects. Several studies suggest that phytochemicals could be considered as appropriate choices for cancer prevention and...
Nearly one in eight US women will develop breast cancer in their lifetime. Most breast cancer is not associated with a hereditary syndrome, occurs in postmenopausal women, and is estrogen and progesterone receptor-positive. Estrogen exposure is an epidemiologic risk factor for breast cancer and estrogen is a potent mammary mitogen. We studied single nucleotide polymorphisms (SNPs) in estrogen r...
Cancer prevention studies suggest that selenium is effective in reducing the incidence of cancers including prostate, colon, and lung cancers. Previous reports showed that selenium inhibits premalignant human breast MCF-10AT1 and MCF10AT3B cell growth in vitro and reduces mammary tumor incidence after exposure to carcinogens in tumor models. Because estrogen is critical to the development and d...
Male breast cancer is a rare disease with an increasing trend. Due to limited information especially about the genetic basis of the disease in Iran and the lower age of its onset, the disease requires more attention. The aim of this study was to screen the male patients with breast cancer for BRCA mutations as well as tissue markers of estrogen receptor (ER), progesterone receptor (PR), human e...
