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

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

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
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]
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]
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
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.
