background: progesterone has been suggested to contribute to the regulation of spermatogenesis and to facilitate the production of viable sperm. investigations have showed that polymorphism of progesterone receptor (pgr) is associated with some diseases. objective: to analyze the potential relationship between male infertility and the +331g/a and progins polymorphisms of pgr gene. materials and...

The aim of this study was to determine: (a) whether progesterone affects the expression of the gene for its own receptor, thereby affecting its own synthesis; (b) whether oxytocin (OT) and noradrenaline (NA) influence the expression of gene for receptor (R) of OT (OT-R), progesterone (PR-R), and β2-R, determined by means of real-time PCR; (c) whether OT, progesterone, and NA affects the protein...

Progesterone and its nuclear receptor are critical in modulating reproductive physiology and behavior in female and male vertebrates. Whiptail lizards (genus Cnemidophorus) are an excellent model system in which to study the evolution of sexual behavior, as both the ancestral and descendent species exist. Male-typical sexual behavior is mediated by progesterone in both the ancestral species and...

The fallopian tube plays an important role in successful female reproduction because it transport gametes to the fertilisation site, nourishes the developing embryo and transports the embryo to the uterus at a suitable time for implantation. The overall aim of this thesis was to investigate the role of progesterone in the control of gamete transport. Ciliary cells are important for the transpor...

BACKGROUND We have previously demonstrated that progesterone has a stimulatory effect on HLA-G gene expression. Because this effect was abolished by the anti-progestin, RU486, we hypothesize that this effect is through receptor-mediated up-regulation of the HLA-G gene. The objective of this study was to explore the molecular mechanisms of this effect. METHODS The transient transfection of a c...

Summary Diagnosis and decision-making in the treatment of breast cancer patients is vastly dependent on exploration biomarkers. Estrogen receptor, progesterone human epidermal growth factor receptor 2 are long-standing biomarkers, which determine subtype. In current practice, gene expression analyses further define molecular subtype give additional information disease characteristics. Prognosti...
