Progesterone
Our best articles related to Progesterone
Progesterone also known as P4 (pregn-4-ene-3,20-dione) is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports ''gestation'') and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestogens, and is the major naturally...
Progesterone was independently discovered by four research groups. Willard Myron Allen co-discovered progesterone with his anatomy professor George Washington Corner at the University of Rochester Medical School in 1933. Allen first determined its melting point, molecular weight, and partial...

In women, progesterone levels are relatively low during the preovulatory phase of the menstrual cycle, rise after ovulation, and are elevated during the luteal phase. Progesterone levels tend to be 5& ng/ml after ovulation. If pregnancy occurs, progesterone levels are ...

progesterone receptor (PR) also known as NR3C3 (nuclear receptor subfamily 3, group C, member 3), is an intracellular steroid receptor that specifically binds progesterone. In humans, PR is encoded by a single ”PGR” gene residing on chromosome 11q22, it has ...
As demonstrated in progesterone receptor-deficient mice, the physiological effects of progesterone depend completely on the presence of the human progesterone receptor (hPR), a member of the steroid-receptor superfamily of nuclear receptors. The single-copy human (hPR) gene uses separate promoters and ...
selective progesterone receptor modulator (SPRM) is an agent that acts on the progesterone receptor. A characteristic that distinguishes such substances from receptor full agonists (such as progesterone) and full antagonists (such as mifepristone) is that their action differs in different ...
Six variable sites, including four polymorphisms and five common haplotypes have been identified in the human PR gene . One promoter region polymorphism, +331G/A, creates a unique transcription start site. Biochemical assays showed that the +331G/A polymorphism increases transcription of ...
In common with other steroid receptors, the progesterone receptor has a N-terminal regulatory domain, a DNA binding domain, a hinge section, and a C-terminal ligand binding domain. A special transcription activation function (TAF), called TAF-3, is present in the progesterone ...
Animal Progesterone is produced in the ovaries (to be specific, after ovulation in the corpus luteum), the adrenal glands (near the kidney), and, during pregnancy, in the placenta. Progesterone is also stored in adipose (fat) tissue. In humans, increasing amounts ...
Estrogen is necessary to induce the progesterone receptors. When no binding hormone is present the carboxyl terminal inhibits transcription. Binding to a hormone induces a structural change that removes the inhibitory action. Progesterone antagonists prevent the structural reconfiguration. After progesterone ...
Progesterone exerts its primary action through the intracellular progesterone receptor although a distinct, membrane bound progesterone receptor has also been postulated. In addition, progesterone is a highly potent antagonist of the mineralocorticoid receptor (MR, the receptor for aldosterone and other ...
The use of progesterone and its analogues have many medical applications, both to address acute situations and to address the long-term decline of natural progesterone levels. Because of the poor bioavailability of progesterone when taken orally, many synthetic progestins have ...
Pill form of progesterone (actually a synthetic version such as Progestogen) taken at 400 mg as cited by the following patent can cause increased fluid retention, which may result in epilepsy, migraine, asthma, cardiac or renal dysfunction. Blood clots that ...Related Videos
