Endocrine-driven malignancies, including breast and prostate cancer, are among the most common human cancers. The relationship between sex steroid hormones (eg, androgen, estrogen, and progesterone), their cognate receptors, and genomic stability lie at the center of endocrine-driven cancer development, progression, and therapeutic resistance. A va...

Following the discovery and approval of the oral contraceptive, the pharmaceutical industry sought new opportunities for the regulation of reproduction. The discovery of the first non-steroidal anti-oestrogen MER25, with antifertility properties in laboratory animals, started a search for 'morning-after pills'. There were multiple options in the 19...

Exposure to physiological estrogens or xenoestrogens (e.g., zearalenone or bisphenol A) increases the risk for cancer. However, little information is available on their significance in ovarian cancer. We present a comprehensive study on the effect of estradiol, zearalenone and bisphenol A on the phenotype, mRNA, intracellular and cell-free miRNA ex...
BACKGROUND: there is no consensus on the cut-off for positivity of estrogen receptor (ER) and progesterone receptor (PR) in endometrial cancer (EC). Therefore we determined the cut-off value for ER and PR with the strongest prognostic impact on outcome. METHODS: immunohistochemical expression of ER and PR was scored as a percentage of positive EC c...

Loss of oligodendrocytes, the myelin-forming cells of the central nervous system, and subsequent failure of myelin development result in serious neurological disorders such as multiple sclerosis. Using primary mouse embryonic neural stem cells (NSCs), we previously demonstrated that donepezil, an acetylcholinesterase inhibitor developed for the tre...

Inorganic arsenic (iAs/As2 O3 2- ) is an environmental toxicant found in watersheds around the world including in densely populated areas. iAs is a class I carcinogen known to target the skin, lungs, bladder, and digestive organs, but its role as a primary breast carcinogen remains controversial. Here, we examined a different possibility: that expo...

Melasma and facial pigmentary demarcation lines (FPDL) are common causes of patterned facial pigmentation that may mimic each other. There is a paucity of studies investigating these two conditions. The objective of this study was to make a detailed comparative analysis of these disorders. A clinical, dermoscopic, histopathological and immunohistoc...
Estetrol (E4), a natural estrogen synthesized by the human fetal liver, is currently evaluated in phase III clinical studies as a new menopause hormone therapy. Indeed, E4 significantly improves vasomotor and genito-urinary menopausal symptoms and prevents bone demineralization. Compared to other estrogens, E4 was found to have limited effects on c...

Uncontrolled cell growth, division, and lack of enough blood supply causes low oxygen content or hypoxia in cancerous tumor microenvironments. 17β-Estradiol (E2), an estrogen receptor (ER) ligand, can be incorporated on the surface of nanocarriers for targeted drug delivery to breast cancer cells overexpressing ER. In the present study, we synthesi...

Mesenchymal stem cells can differentiate into mature chondrocytes, osteoblasts, and adipocytes. Excessive and dysfunctional visceral adipocytes increase upon menopause and importantly contribute to altered metabolism in postmenopausal women. We previously showed both plasma membrane and nuclear estrogen receptors alpha (ERα) with endogenous estroge...
