title: Estradiol regulates N-cadherin mRNA levels in the mouse ovary.
abstract: N-cadherin (N-cad) is a calcium-dependent cell adhesion molecule which is present in the granulosa cells of the mouse ovarian follicle. This cell adhesion molecule has been implicated as a key modulator of follicular development. The regulators of N-cad mRNA levels in the ovary have not been identified. We have examined the ability of steroids to influence ovarian N-cad mRNA levels in vivo. Immature mice were injected with either progesterone, testosterone, 17 beta-estradiol, or 17 alpha-estradiol. Only 17 beta-estradiol caused a rapid and significant increase in the ovarian N-cad mRNA levels. We speculate that this steroid is a major regulator of N-cad-mediated granulosa cell interactions in vivo.
