Double oestrogen receptor alpha and beta knockout mice reveal differences in neural oestrogen-mediated progestin receptor induction and female sexual behaviour.


To test the hypothesis that oestrogen receptor alpha (ERalpha) and ERbeta act together to mediate the actions of oestrogen in the ventromedial hypothalamus (VMH), we used mice with single or double knockout mutations of the ERalpha and ERbeta genes. Ovariectomized mice were implanted with 17beta-oestradiol and killed 5 days later. Oestradiol treatment… (More)
