Progesterone (NSC 9704, NSC 64377, Pregn-4-ene-3,20-dione) is an endogenous steroid hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. A potent agonist of thenuclear progesterone receptor (nPR)withKdof 1 nM; In vitro
Progesterone has biphasic effects on proliferation of breast cancer cells; it stimulates growth in the first cell cycle, then arrests cells at G1/S of the second cycle accompanied by up-regulation of the cyclin-dependent kinase inhibitor, p21. Progesterone-mediated transcription is further prevented by overexpression of E1A, suggesting that CBP/p300 is required. Progesterone drives a series of events where luminal cells probably provide Wnt4 and RANKL signals to basal cells which in turn respond by upregulating their cognate receptors, transcriptional targets and cell cycle markers. Progesterone treatment increases the sensitivity of cortical synaptoneurosomes to GABA (i.e., decreased the EC50) and increases the maximal efficacy with which GABA stimulated Cl- transport (i.e., increased the Emax).
In vivo
Progesterone blocks the beneficial effect of estrogen on Abeta accumulation but not on behavioral performance in female 3xTg-AD mice. Progesterone significantly reduces tau hyperphosphorylation when administered both alone and in combination with estrogen. Progesterone-treated rats are less impaired on a Morris water maze spatial navigation task than rats treated with the oil vehicle. Progesterone-treated rats also show less neuronal degeneration 21 days after injury in the medial dorsal thalamic nucleus, a structure that has reciprocal connections with the contused area.
