Androgen receptors are important transcription factors regulating the expression of a number of genes in androgen-responsive cells and may play a role in prostate cancer. This article describes transcriptional suppressors and other transcription factors which may play important roles in modulating t

β¦ Synopsis
BACKGROUND.
The growth and function the normal prostate is dependent on the presence of androgen. As prostate tumors progress there is a loss of androgen-dependent cell growth. The identification of the genes that are regulated by androgens may be of pathological and clinical significance. METHODS. In this study the differential display method was used to idenhfy genes regulated by androgen in an androgen-responsive prostate cancer cell line, LNCaP-FGC. RESULTS. A gene whose expression is down-regulated in LNCaP-FGC cells after 30 hr of androgen deprivation has been identified. This gene is a previously identified member of the SlOO gene family of calcium-binding proteins, namely SlOOP. Here we show that SlOOP expression is regulated by the synthetic androgen R1881, but not by serum growth factors. It is dysregulated in the androgen-independent prostate cancer cell lines LNCaP-R, DU145, and PC3. CONCLUSIONS. The data indicate that SlOOP may play a role in the etiology of prostate cancer.

## BACKGROUND. The adult prostate is maintained through an equilibrium between cell growth and death rates. Androgen deprivation induces an increase in intracellular Ca ++ , AP-1 gene expression of androgen-inducible genes. METHODS. Northern blot analysis, band-shift assays, and transient cotransf
The androgen receptor (AR) belongs to the superfamily of nuclear receptors that employ complex genetic mechanisms to guide the development and physiological functions of different target tissues. Upon interaction with its cognate hormone, AR activates or represses gene transcription through associat
Androgens exert profound effects on the organization and function of the central nervous system. These effects are mediated by the androgen receptor (AR), a ligand-dependent transcription factor. The mechanisms of AR regulation in neural tissue, however, remain to be fully elucidated. Characterizing
