The receptor interacting protein 140 (RIP140) belongs to a unique subclass of nuclear receptor coregulators with the ability to bind and repress the action of a number of agonist-bound hormone receptors. We have previously demonstrated that all-trans-retinoic acid (RA) induction of RIP140 constitutes a rate-limiting step in the regulation of retinoid receptor signaling. Here we demonstrate that...

The role of sex hormones in the pathogenesis of lung cancer is still unknown. There are conflicting results regarding immunohistochemical detection of the estrogen and progesterone receptors expression in non small cell lung cancer. To clarify these discrepancies 32 samples of lung carcinoma tissues obtained by lobectomy or pneumonectomy were studied. Two monoclonal antibodies (6F11 and ID5) fo...

objective: breast cancer is the most common cancer in iranian women. breast tumors are classified based on the estrogen receptor alpha (erα) expression status into er negative and er positive tumors. er negative tumors tend to have worse prognosis and less likely to respond to endocrine therapy. aberrant methylation of gene promoter is one of the mechanisms for gene silencing in breast tumors. ...

Estrogen-induced apoptosis has become a successful treatment for postmenopausal metastatic, estrogen receptor-positive breast cancer. Nitric oxide involvement in the response to this endocrine treatment and its influence upon estrogen receptor-positive breast cancer progression is still unclear. Nitric oxide impact on the MCF7 breast cancer line, before and after estrogen-induced apoptosis, was...

OBJECTIVE Estrogen receptor expression in lung cancer has been understudied, particularly in light of its potential biologic importance in the epidemic of lung cancer in women. The expression of estrogen receptors was investigated to better understand the possible role of sex hormones in lung cancer. METHODS A total of 301 patients with surgically resected non-small cell lung cancers of stage...

this study focused on triple-negative breast cancer (tnbc) that is characterized by the lack of expression of estrogen receptor (er), progesterone receptor (pr), and human epidermal growth factor receptor 2 (her-2). the primary goal of this study was to describe the relation between triple-negative receptor status and survival. this is the first study about triple-negative breast cancer in our ...

Background: The organochlorine DDT has estrogenic activity but the mechanism underlying the estrogenic activity of this pesticide remains unclear. In the present investigation here, we studied the transcriptional effects of a synthetic organochlorine pesticide o,p’-DDT [1.1.1.-trichloro-2-(o-chlorophenyl)-2-p-chloriphenyl ethane] and its metabolite p,p'-DDE (2-2-bis(4/chlorophenyl)-1-1-di...

granymeh is a functional cytotoxic serine protease of nk cell granules,which expands the cell death-inducing repertoire of innate immune system.the purpose of this study was to determine granymeh(gzmh)level in breast cancer(bc) and healty women.this study was performed on 30 patients with bc and 30 healty woman.gzmh and estrogen levels were measured in cancer patients  and healty women subseque...

Introduction: Triple-negative breast cancer (TNBC) is a type of breast cancer that is negative for estrogen receptor, progesterone receptor, and HER2. This study aimed to evaluate the clinical outcomes and short-term prognosis of this type of cancer compared with other subtypes of breast cancer. Methods: A cross-sectional study was conducted on 108 women with invasive breast cancer. The patie...
