Objective(s): Neuroprotective effects of female gonadal steroids are mediated through several pathways involving multiple peptides and receptors after traumatic brain injury (TBI). Two of these peptides are including the regulatory peptides neuromedin U (NMU) and neuromedin S (NMS), and their common receptor neuromedin U2 receptor (NMUR2). This study investigates the effects of physiological do...

In the kidney, progesterone is inactivated to 20alpha-dihydro-progesterone (20alpha-DH-progesterone) to protect the mineralocorticoid receptor from progesterone excess. In an attempt to clone the enzyme with 20alpha-hydroxysteroid activity using expression cloning in CHOP cells and a human kidney expression library, serendipitously cDNA encoding CYP27A1 was isolated. Overexpression of CYP27A1 i...

The clinical response of advanced endometrial adenocarcinoma to progestin therapy does not correlate perfectly with biochemically assayed progesterone receptor status of the tumor. We have previously suggested that heterogeneity of progesterone receptor at the cellular, tumor, and tissue levels, not detectable by the biochemical assay, might contribute to this discrepancy. A monoclonal antibody...

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 focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone), or...

The present study was designed to determine whether progesterone might have a role in gonadotrophin-induced pituitary adenylate cyclase-activating polypeptide (Pacap) gene expression in rat ovary. Northern blot analysis revealed that treatment of pregnant mare's serum gonadotrophin (PMSG)-primed immature rats with the progestin antagonist RU486 or an inhibitor of 3beta-hydroxysteroid dehydrogen...

Genus and Species. Sus scrofa. Locus. Pig Progesterone Receptor ( PGR) gene. Source and Description of Primers. Oligonucleotide primers were designed from a partial pig PGR cDNA sequence (Genbank accession no. S49016) with inferred intron-exon boundary information from humans (Misrahi et al., 1993). The primers were designed to span the intron between exons 7 and 8 of the PGR gene.

To investigate the molecular mechanism of Ziziphi spinosae semen and Schisandrae chinensis fructus in treatment insomnia is objective study. First, compounds corresponding target genes were obtained by traditional Chinese medicine systems pharmacology database analysis platform associated with GeneCards database. The results imported into Cytoscape software to construct a network (Herbal-active...
