The Neandertal Progesterone Receptor [PDF]

open access: yesMolecular Biology and Evolution, 2020
Abstract The hormone progesterone is important for preparing the uterine lining for egg implantation and for maintaining the early stages of pregnancy. The gene encoding the progesterone receptor (PGR) carries introgressed Neandertal haplotypes with two missense substitutions and a mobile Alu element.

Loss of progesterone receptor-mediated actions induce preterm cellular and structural remodeling of the cervix and premature birth. [PDF]

open access: yesPLoS ONE, 2013
A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the ...

Establishment of a graphene quantum dot (GQD) based steroid binding assay for the nuclear progesterone receptor (pgr) [PDF]

open access: yesBiochemistry and Biophysics Reports
Previously, we established a homogeneous assay for membrane progesterone receptor alpha (mPRα) ligands by conjugating semiconductor nanoparticles known as graphene quantum dots (GQDs) to mPRα. When mixed with a progesterone-BSA-fluorescein isothiocyanate

Expression of Progesterone Receptor and Its Association with Clinicopathological Characteristics in Meningiomas: A Cross-Sectional Study

open access: yesWorld Neurosurgery: X, 2021
Background: Meningiomas that are progesterone receptor positive have a low recurrence rate and good prognosis compared to those that are progesterone receptor negative.

Progesterone receptor expression declines in the guinea pig uterus during functional progesterone withdrawal and in response to prostaglandins. [PDF]

open access: yesPLoS ONE, 2014
Progesterone withdrawal is essential for parturition, but the mechanism of this pivotal hormonal change is unclear in women and other mammals that give birth without a pre-labor drop in maternal progesterone levels.

A nongenomic mechanism for progesterone-mediated immunosuppression: Inhibition of K+ channels, Ca2+ signaling, and gene expression in T lymphocytes [PDF]

open access: yes, 1998
The mechanism by which progesterone causes localized suppression of the immune response during pregnancy has remained elusive. Using human T lymphocytes and T cell lines, we show that progesterone, at concentrations found in the placenta, rapidly and ...

Progesterone Signaling and Mammalian Ovarian Follicle Growth Mediated by Progesterone Receptor Membrane Component Family Members

open access: yesCells, 2022
How progesterone influences ovarian follicle growth is a difficult question to answer because ovarian cells synthesize progesterone and express not only the classic nuclear progesterone receptor but also members of the progestin and adipoQ receptor ...

Reproductive functions of the progesterone receptor [PDF]

open access: yesJournal of the Society for Gynecologic Investigation, 2000
The steroid hormone progesterone plays a central role in the reproductive events associated with pregnancy establishment and maintenance. Physiological effects of progesterone are mediated by interaction of the hormone with specific intracellular progesterone receptors (PRs) that are expressed as two protein isoforms, PR-A and PR-B. Both proteins arise

Intestinal tumorigenesis is not affected by progesterone signaling in rodent models. [PDF]

open access: yesPLoS ONE, 2011
Clinical data suggest that progestins have chemopreventive properties in the development of colorectal cancer. We set out to examine a potential protective effect of progestins and progesterone signaling on colon cancer development.

The importance of simultaneous determination of breast cancer biomarkers [PDF]

open access: yesArchive of Oncology, 2002
It is shown that steroid hormone receptors by themselves are not sufficiently strong prognostic factors in management of breast cancer. For that reason, simultaneous consideration of different biomarkers seems to be more appropriate for clinical use, i.e.
