1 OBJECTIVE: The purpose of this study was to determine the role of 5beta-dihydroprogesterone (5beta-DHP), acting through the nuclear receptor pregnane X receptor (PXR), in regulating uterine contractility. 5-alpha-Dihydroprogesterone nuclear receptor subfamily 1, group I, member 2 Mus musculus
2 OBJECTIVE: The purpose of this study was to determine the role of 5beta-dihydroprogesterone (5beta-DHP), acting through the nuclear receptor pregnane X receptor (PXR), in regulating uterine contractility. 5-alpha-Dihydroprogesterone nuclear receptor subfamily 1, group I, member 2 Mus musculus
3 OBJECTIVE: The purpose of this study was to determine the role of 5beta-dihydroprogesterone (5beta-DHP), acting through the nuclear receptor pregnane X receptor (PXR), in regulating uterine contractility. 5-alpha-Dihydroprogesterone nuclear receptor subfamily 1, group I, member 2 Mus musculus
4 OBJECTIVE: The purpose of this study was to determine the role of 5beta-dihydroprogesterone (5beta-DHP), acting through the nuclear receptor pregnane X receptor (PXR), in regulating uterine contractility. 5-alpha-Dihydroprogesterone nuclear receptor subfamily 1, group I, member 2 Mus musculus
5 Chronic in vivo administration of 5beta-DHP to mice with intact PXR, but not in mice with disrupted PXR, causes an increased effect of 1400W, a specific inhibitor of inducible nitric oxide synthase (iNOS). 5-alpha-Dihydroprogesterone nuclear receptor subfamily 1, group I, member 2 Mus musculus
6 Chronic in vivo administration of 5beta-DHP to mice with intact PXR, but not in mice with disrupted PXR, causes an increased effect of 1400W, a specific inhibitor of inducible nitric oxide synthase (iNOS). N-((3-(aminomethyl)phenyl)methyl)ethanimidamide nuclear receptor subfamily 1, group I, member 2 Mus musculus
7 CONCLUSION: These data support the hypothesis that metabolites of progesterone may act chronically through a PXR-mediated mechanism to regulate uterine contractility. Progesterone nuclear receptor subfamily 1, group I, member 2 Mus musculus
