The human estrogen-related receptor 1 (ERR 1) is a member of an orphan receptor family closely related to the estrogen receptor. It has been demonstrated that estrogen modulates endothelial nitric oxide synthase (eNOS) expression through the estrogen receptor in endothelial cells. However, little is known about the relationship between ERR 1 and eNOS. In this study, we show that ERR 1 activates...

MCF-7 cells have been shown to contain estrogen receptor in several cell fractions following homogenization: nuclei, microsomes, and cytosol. The amount of 17 beta-estradiol-binding capacity found in each cellular compartment depended on the inclusion of detergent in homogenization buffers and on the use of 0.25 M sucrose in the nuclear washes. 17 beta-Estradiol receptor (E2R) associated with n...

A subclone of rat pituitary tumor cells, designated GH3/C14, was isolated from the parent population of GH3 pituitary cells and was estrogen-dependent for growth in vivo. GH3/C14 cells inoculated into host animals formed tumors in intact females, estrogen-treated ovariectomized females, and estrogen-treated males, but not in untreated intact or castrated males, or untreated ovariectomized femal...

PURPOSE To determine if a commonly used soy protein supplement exhibits biological activity in vivo and in vitro, we evaluated an over-the-counter soy protein powder supplement using blood from healthy male volunteers and in an estrogen receptor in vitro assay. SUBJECTS AND METHODS We recruited healthy male volunteers 18 years of age or older that were in good health. Treatment consisted of c...

(i) Objective: This study was conducted to analyze the effect of lead acetate on the serum estrogen and progesterone levels in adult mice and the role of garlic extract. (ii) Study Design: Laboratory based Randomized Control Trial. (iii) Place and duration of study: Anatomy Department, Army Medical College, Rawalpindi in collaboration with National Institute of health from April-June 2013. (iv)...

This study was carried out to investigate the effects of the Achyrantes japonica (A. japonica) extract on serum level of hormones from osteoporosis induced ovariectomized rats. Two month-old rats were ovariectomized (OVX), remained untreated for 8 weeks, and were subsequently administered A. japonica (300 mg/kg) every day for 8 weeks. We examined the effects of treated A. japonica every 10 days...

BACKGROUND Glutamate is found in a wide variety of foods. It induces the uterine fibroid in the rats by increasing the levels of estradiol. Diltiazem is an effective preventive medication. This study was conducted to analyse the effect of monosodium glutamate on the serum estrogen and progesterone levels in adult Sprague Dawley rat and its prevention with diltiazem. METHODS This Laboratory ba...

AIM The study was conducted to determine the serum levels of certain hormones in post-partum anestrus cows following treatment with controlled internal drug release (CIDR) and Ovsynch protocol. MATERIALS AND METHODS A total of 30 postpartum anestrus cows were divided into three equal groups after thorough gynecoclinical examination. The Group 1 animals received an intravaginal progesterone de...

Minerly, PhD; Karen Weierstall, PhD; Deirtra Hunter, MA; Weilun Sun, MA; Jan Weiner, BA; Shirzad Jenab, PhD; Vanya Quinones-Jenab, PhD Evidence suggests that sex differences in response to cocaine administration may be regulated by activation of progesterone and estrogen receptors. To test this hypothesis, rats ...
