Regulation of Kiss1 expression by sex steroids in the amygdala of the rat and mouse.

abstract：:Earlier studies have shown that lactation-induced bone loss in the rat is both PTH- and vitamin D-independent and have suggested the involvement of another, as yet unidentified, factor(s) in the altered calcium metabolism which accompanies lactation. In the present study, we investigated the possibility that PTH-relat...
