Effects of testosterone and 2-hydroxyflutamide on progesterone receptor expression in porcine ovarian follicles in vitro.
The purpose of the study was to test the possible role of the androgen receptor (AR) agonist (testosterone; T), an AR antagonist (2-hydroxyflutamide; 2-Hf) or combination of both (T+2-Hf) on progesterone receptor (PGR) expression in cultured porcine granulosa cells (GCs) or whole follicles. GCs isolated from mature pig follicles (6-8mm in diameter) were cultured for 48 h. Experimental cultures ...
متن کاملEstrogen, Progesterone and Epithelial Ovarian Cancer
Ovarian carcinoma (OCa) continues to be the leading cause of death due to gynecologic malignancies and the vast majority of OCa is derived from the ovarian surface epithelium (OSE) and its cystic derivatives. Epidemiological evidence strongly suggests that steroid hormones, primarily estrogens and progesterone, are implicated in ovarian carcinogenesis. However, it has proved difficult to fully ...
متن کاملexpression of e-cadherin, leukemia inhibitory factor and progesterone receptor in mouse blastocysts after ovarian stimulation
objective: the appropriate interaction between a blastocyst and the endometrium is essential for successful implantation. numerous factors, including hormone receptors (progesterone receptor), cytokines [leukemia inhibitory factors (lif)], and adherence molecules such as e-cadherin are involved in the cross-talk that occurs between the embryo and endometrium. studies show that a lack of these g...
متن کاملI-24: Individualized Controlled Ovarian Stimulation (iCOS)
Background: With the recent development of recombinant gonadotropins (FSH and LH), it has become possible to further adjust the stimulation protocol according to the expected needs of the patient. In this respect, the possible beneficial role of exogenous LH activity supplementation for stimulated ART cycles has received increasing attention. According to the two-cell, two- gonadotropin theory,...
متن کاملQuantifying growing versus non-growing ovarian follicles in the mouse
BACKGROUND A standard histomorphometric approach has been used for nearly 40 years that identifies atretic (e.g., dying) follicles by counting the number of pyknotic granulosa cells (GC) in the largest follicle cross-section. This method holds that if one pyknotic granulosa nucleus is seen in the largest cross section of a primary follicle, or three pyknotic cells are found in a larger follicle...
