RISK FACTORS STUDY OF THREATENED ABORTION OCCURRING IN WOMEN WITH REGARD TO PROGESTERONE RECEPTOR GENE POLYMORPHISM

open access: yesМедична наука України, 2017
Relevance. An important medical and social problem of modern obstetrics is threatening abortion. Among all threatened abortion risk factors today a special attention is given to genetic factors, in particular, to progesterone receptor gene polymorphism ...

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.

The rate of estrogen receptor‐conversion associated with tumor progression in estrogen receptor‐positive breast cancer patients following adjuvant Tamoxifen administration

open access: yesCancer Reports, 2022
Background Hormone Receptor (HR)‐discordance between primary breast cancer and metastasis is a known biological phenomenon. Discordance studies usually comprise a heterogeneous group of HR‐positive and negative patients and allow for the comparison of ...

Gynaecological uses of a new class of steroids: the selective progesterone receptor modulators [PDF]

open access: yes, 2009
Selective progesterone receptor modulators (SPRM) represent a new class of synthetic steroids, which can interact with the progesterone receptor (PR) and can exert agonist, antagonist or mixed effects on various progesterone target tissues in vivo.

Hypothalamic effects of progesterone on regulation of the pulsatile and surge release of luteinising hormone in female rats

open access: yesScientific Reports, 2017
Progesterone can block the oestradiol-induced GnRH/LH surge and inhibit LH pulse frequency. Recent studies reported that progesterone prevented premature LH surges during ovarian hyperstimulation in women. As the most potent stimulator of GnRH/LH release,

Estrogen and Progesterone Receptors in the Endometrium

open access: yesAnnals of the New York Academy of Sciences, 1997
The endometrium, as a target of estrogens and progestins, possesses the respective receptor proteins. These receptors belong to the superfamily of nuclear receptors, having important functional domains required for steroid ligand binding, for dimer formation, for interaction with HREs of DNA, for transcription modulation, for association with other ...

Synthetic epoxy-pregnan steroids: effects on anxiety behavior in rats [PDF]

open access: yes, 2016
Neurosteroids like 3α-OH-5α-pregnan-20-one (allopregnanolone) and 3α-OH-5β-pregnan-20-one (pregnanolone) modulate the γ-aminobutyric acid-A (GABAA) receptor function and produce several effects that can be considered for therapeutical pruposes like ...

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

open access: yes, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Progesterone differentially affects the transcriptomic profiles of cow endometrial cell types

open access: yesBMC Genomics, 2022
Background The endometrium is a heterogeneous tissue composed of luminal epithelial (LE), glandular epithelial (GE), and stromal cells (ST), experiencing progesterone regulated dynamic changes during the estrous cycle.

Genetic polymorphisms in eostrogen and progesterone receptor genes in Papio anubis induced with endometriosis during early stage of the disease

open access: yesAIMS Molecular Science, 2021
Genetic predisposition has been suggested to play a role in the pathogenesis of endometriosis. The most common pathogenetic hypotheses is that there is possible dysregulation of the ligand-receptorial signaling involving the main sex hormones, eostrogen ...
