some lesions in the oral cavity and mostly on gingiva have predominant predilection towards females, and mostly occur in the first four decades of life when changes in sex hormone levels in blood are obvious. the present study aimed to investigate the presence and distribution of estrogen and progesterone receptors in peripheral giant cell granuloma (pgcg), pyogenic granuloma (pg) and periphera...

Oviduct nuclei from laying hens, or from chicks given an optimal dose of estrogen, contain receptors with a high affinity for 17beta-estradiol (apparent Kd of about 3.7 nM) at a concentration of about 10,600 molecules per tubular gland cell. Chicks withdrawn from estrogen stimulation exhibit a 7-fold lower level of nuclear estrogen receptors. Radioimmunoassay of 17beta-estradiol in the serum in...

background and objectives: presence of steroid hormone receptors (estrogen and progesterone) in the tumor tissues of various organs correlates with response to therapy and prognosis. since their role in ovarian cancer is still controversial, in this study we investigated the expression and prognostic value of the estrogen receptor (er) and progesterone receptors (pr) in ovarian papillary serous...

Bisphenol-A (BPA) is an industrial xenoestrogen used widely in our living environment. Recently, several studies suggested that BPA has destructive effects on DNA and chromosomes in normal body cells via estrogen receptors (ER). Therefore, BPA could be considered as an important mediator in many diseases such as cancer. However, there are still many controversial issues which need clarification...

The effects of estrogen are mediated through two functionally distinct receptors, estrogen receptor alpha (ER- alpha ), and estrogen receptor beta (ER- beta ), both of which are expressed in the cardiovascular system. The etiology of cardiovascular disease is believed to result in part from the loss of endogenous estrogen, indicating that estrogen and its receptors may play important roles in t...
