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...
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...
background and objective: breast cancer is the commonest cancer of indian women. estrogen and progesterone expression is seen in benign breast lesions and in breast carcinoma associated with good prognostic parameters and it correlates well with response to hormone therapy. although a lot of studies have been conducted in the past on hormone receptor expression in breast cancer and few have cor...
the hippocampal system plays an important role in memory function. neurohormones like androgens and estrogens that syntheses in hippocampus have an important role in learning and memory. many biological effects of estrogens in the brain via estrogenic receptors (ers) are investigated. the current research has conducted to assess the effect of estrogenic receptors on spatial discrimination in ra...
background: phytoestrogens, a group of plant-derived polyphenolic compounds have recently come into considerable attention due to the increasing information on their potential adverse effects in human health. some of phytoestrogens show estrogenic activity that may be carcinogenic for human. in the present study, we investigated the transcriptional effects of variety of phytoestrogens on the bo...
alzheimer’s disease (ad) is a disorder with multiple pathophysiological causes, destructive outcomes, and no available definitive cure. pelargonidin (pel), an anthocyanin derivative, is an estrogen receptor agonist with little estrogen side effects. this study was designed to assess pel memory enhancing effects on the a rat amyloid beta 25-35 (aβ) intrahippocampal microinjections model of ad in...

Background & Objective: Gliomas are the most common type of primary intracranial tumors in adults. The expression of estrogen receptors varies in different grades of glial tumors, and some studies have suggested that this expression might have a prognostic value. It seems that estrogen receptor expression negatively correlates with the histological grade of gliomas. In the pres...
Dear Editor-in-ChiefMalignant melanoma is a tumor arising from melanocyte; this tumor rarely occurs before puberty, with higher mortality rate in males and better survival rate in female patients affected by metastatic melanoma (1, 2). These facts propose that a relationship and association may exist between estrogens and melanoma. The effects of estrogens are mediated by...
in human breast cancer, estrogen receptor (er) status of the tumor has prognostic and therapeutic significance. however, facilities to study er are not widely available to us. we postulated that if there is a correlation between histologic grade and er status of invasive ductal carcinoma (idc), it may help predict the er status of the tumor. of 8 4 cases of breast carcinoma referred to the canc...
