Abstract: | The kidneys of androgen stimulated mice exhibit a hypertrophic response but no hyperplasia or concomitant DNA replication. Androgens increase the expression of several genes in mouse kidney. The response of the beta-glucuronidase gene to testosterone in this tissue is characterized by a 1-2 day lag and relatively slow induction kinetics. The gene coding for kidney androgen-regulated protein (KAP) exhibits quite a different response to the hormone when compared on the basis of initial response to a given dose, dose required to produce maximal response, and apparent sensitivity to low levels of androgen-receptor complexes in renal nuclei. The analysis of the accumulation of the mRNAs produced by these two genes suggests that gene-specific differential sensitivity to androgen receptor complexes governs the development of the cellular male phenotype in this tissue. |
