3-Methylcholanthrene (3MC) is an aryl hydrocarbon receptor (AhR) agonist, and it has been reported that 3MC induces estrogenic activity through AhR-estrogen receptor alpha (ER alpha) interactions. In this study, we used 3MC and 3,3',4,4',5-pentachlorobiphenyl (PCB) as prototypical AhR ligands, and both compounds activated estrogen-responsive reporter genes/gene products (cathepsin D) in MCF-7 b...
In women, estrogen deficiency after menopause frequently accelerates osteoclastic bone resorption, leading to osteoporosis, the most common skeletal disorder. However, mechanisms underlying osteoporosis resulting from estrogen deficiency remain largely unknown. Here we show that in bone-resorbing osteoclasts, estrogen-dependent destabilization of hypoxia-inducible factor 1 alpha (HIF1α), which ...
Hormones play an important role in pathophysiology. The hormone receptors, such as estrogen receptor alpha and androgen receptor in breast cancer and prostate cancer, are critical to cancer cell proliferation and tumor growth. In this review we focused on the cross-talk between hormone and hypoxia pathways, particularly in breast cancer. We delineated a novel signaling pathway from estrogen rec...
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...
