Effect of androgen on the transcription of rat prostatic binding protein genes
Abstract:
The mechanisms whereby androgens modulate mRNA levels for the C1, C2 and C3 prostatic binding protein genes in the rat ventral prostate have been investigated. Transcription rates for the 3 genes were lowered 2-3-fold upon castration but found to increase again upon re-administration of testosterone. Although this demonstrated a direct effect of androgens at the transcriptional level for these genes, the rates of mRNA synthesis were insufficient to account for previously observed steady-state measurements. This was confirmed by analysis of the nuclear steady-state levels for each mRNA following hormonal manipulation of the rats in vivo. It is concluded that besides direct transcriptional regulation, androgens must also exert a major effect of the half-life of these mRNAs in the rat ventral prostate.
