title: [Demonstration of a sex differentiation in the content of androgen receptors in the liver cytosol of rats].
abstract: The paper is concerned with differential quantification of the level of androgen receptors (AR) in the liver cytosol of male and female rats as well as in the prostatic cytosol. AR affinity to synthetic androgen R1881 was shown to be similar in all investigated tissues. In male rats the AR content in the liver cytosol was 20.5 +/- 2.1 fmol per 1 mg of protein, lower (p less than 0.05) than in the prostatic cytosol (30.8 +/- 2.5 fmol per 1 mg of protein). Sex differentiation of the liver AR content with 3-fold predominance in males was determined. Gonadectomy of mature rats caused leveling down of sex differences in the liver AR content as a result of a decrease in AR concentration in castrated males and its increase in ovariectomized females. Sex differentiation of the liver AR content could be an additional factor enhancing the multiple differentiating action of androgens on the male rat liver.
