Changes in ovaries and uterus after aglepristone administration in the third week of luteal phase of non-pregnant bitches. [PDF]

open access: yesPLoS ONE, 2015
The mechanism of aglepristone action in the placentation time in the bitch remains unclear. The aim of this study was to describe the mechanism by which aglepristone influences ovaries and uterus and to measure the levels of steroid sex hormones in non ...

Human amniotic fluid glycoproteins expressing sialyl Lewis carbohydrate antigens stimulate progesterone production in human trophoblasts in vitro [PDF]

open access: yes, 2004
Background: Progesterone is thought to mediate immune modulator effects by regulating uterine responsiveness. The aim of the study was to clarify the effect of transferrin and glycodelin A (former name PP14) as sialyl Lewis X-expressing glycoproteins on ...

Placental weight and mortality in premenopausal breast cancer by tumor characteristics [PDF]

open access: yes, 2013
Placental weight may be regarded as an indirect marker of hormone exposures during pregnancy. There is epidemiological evidence that breast cancer mortality in premenopausal women increases with placental weight in the most recent pregnancy.

Rodent Models of Non-classical Progesterone Action Regulating Ovulation

open access: yesFrontiers in Endocrinology, 2017
It is becoming clear that steroid hormones act not only by binding to nuclear receptors that associate with specific response elements in the nucleus but also by binding to receptors on the cell membrane. In this newly discovered manner, steroid hormones

Steroid hormone bioavailability is controlled by the lymphatic system

open access: yesScientific Reports, 2021
The steroid hormone progesterone accounts for immune tolerance in pregnancy. Enhanced progesterone metabolism to 6α-OH-pregnanolone occurs in complicated pregnancies such as in preeclampsia with preterm delivery or intrauterine growth restriction, and in

The Association between Vitamin D Receptor Expression and Prolonged Overall Survival in Breast Cancer. [PDF]

open access: yes, 2012
Summary In this study, we analyzed vitamin D receptor (VDR) expression and survival in a breast cancer patient cohort of 82 breast cancer patients. Immunohistochemical analysis was possible in 91.5% of the patients (75/82). Staining was evaluated using

Membrane Progesterone Receptors (mPRs/PAQRs) Are Going beyond Its Initial Definitions

open access: yesMembranes, 2023
Progesterone (PRG) is a key cyclical reproductive hormone that has a significant impact on female organs in vertebrates. It is mainly produced by the corpus luteum of the ovaries, but can also be generated from other sources such as the adrenal cortex ...
