The cyclin-dependent kinase inhibitor p57(kip2) regulates the cell cycle of trophoblastic cells. It has been established by a Japanese group that the heterozygous p57(kip2) knockout (p57(-/+)) mice are a good model of preeclampsia as they develop hypertension, proteinuria, and placental...

Exposure to a stressor sensitizes behavioral and hormonal responses to future stressors. Stress-associated release of noradrenaline enhances the capacity of central synapses to show plasticity (metaplasticity). We found noradrenaline-dependent metaplasticity at GABA synapses in the paraventricular nucleus of the hypothalamus...
