(Submitter supplied) Androgens are a prequisite for the development of human prostate and prostate cancer. Androgen action is mediated via androgen receptor. Androgen ablation therapy is used for the treatment of metastasized prostate cancer. The aim of the study was to identify genes differentially expressed in benign human prostate, prostate cancer and in prostate tissue three days after castration. These genes are potential diagnostic and therapeutic targets for prostate cancer and benign prostatic hyperplasia. more...

(Submitter supplied) Introduction: Androgen deprivation therapy (ADT) remains the primary treatment for advanced prostate cancer (PCa). The efficacy of ADT has not been rigorously evaluated by demonstrating suppression of prostatic androgen activity at the target tissue and molecular level. We determined the efficacy and consistency of medical castration in suppressing prostatic androgen levels and androgen-regulated gene-expression. more...

(Submitter supplied) Prostate cancer is the most common cancer in men and androgen receptor (AR) downstream signalings promote prostate cancer cell proliferation. To investigate the AR signaling, we performed directional RNA sequence analysis in AR positive prostate cancer cell line, LNCaP and VCaP. Using Noncode and GENCODE data sets. We identified androgen-regulated long non-coding RNAs (lncRNAs) in prostate cancer cells.

(Submitter supplied) The text description is: LNCaP are androgen receptor expressing prostate carcinoma cells. Genital skin fibroblasts also express the androgen receptor. Cells were either proliferating or they were G0-arrested. Treatment of cells was performed with either the androgen DHT (dihydrotestosterone), the androgen analogue R1881 (methyltrienolone), or the solvent ethanol. Some hybridizations were performed in the type 1 design. more...

(Submitter supplied) LNCaP cells are an established androgen receptor expressing prostate carcinoma cell line. Human foreskin fibroblasts also expressing the androgen receptor were obtained from phenotypic normal male individuals. Cells were cultured either at confluency leading to G0 cell cycle state or while they were proliferating. Cells were either untreated, or treated with dihydrotestosterone (DHT) or ethanol (ETOH) which also served as the solvent for the DHT. more...

(Submitter supplied) C4-2B prostate cancer cells were transfected with siRNA against a non-specific (NS) sequence, siRNA specifically targeting EP300, or siRNA specifically targeting CREBBP. We tested the hypothesis that their exists different subgroups of genes that are preferentially affected by p300 or CBP depletion.

(Submitter supplied) ABSTRACT The effects of DHEA were compared with those of DHT using gene expression array profiles in human LNCaP prostate cancer cells. LNCaP cells were exposed to DHEA (300 nM), DHT (300 nM), or vehicle for 48 hrs, and mRNA was isolated. mRNA expression was measured using Affymetrix HU-95 gene chips in 3 experiments performed on different dates. Gene expression values for the two treatment groups and control were sorted in ascending order on the p-values corresponding to a variance stabilized Hotelling test, which measured the extent of differential RNA expression between control and either hormone treatment. more...

(Submitter supplied) In this study, we used microarray analysis to determine gene expression profile changes in the mouse prostate following castration and hormone replacement. We first identified genes with significant expression changes in each of these two processes and then generated a list of androgen responsive genes and a list of genes whose expression were inversely correlated with the presence of androgen. The analysis of this data set is described in Wang et al., Differentiation, 2006 Keywords: Time course
