title: Androgen-dependent modulation of calbindin-D28K in hypothalamic tissue during prenatal development.
abstract: We examined the influence of androgens on fetal medial basal hypothalamic and preoptic area (MBH-POA) calbindin-D28K levels (via Western analysis) by treating pregnant rats with testosterone or flutamide, (an androgen receptor blocker). MBH-POA calbindin-D28K levels were significantly decreased in flutamide-treated male fetuses, whereas, MBH-POA calbindin-D28K levels were significantly increased in testosterone-treated female fetuses compared to controls. These results suggest that MBH-POA calbindin-D28K is modulated during prenatal development by androgens.
