(Submitter supplied) cDNA expression arrays on a panel of human prostate cancer xenografts. The xenografts can divided into three groups: 1) androgen-dependent, 2) androgen-independent with functional expression of the androgen receptor, 3) androgen-independent lacking functional expression of the androgen receptor. Four microarrays were performed per xenograft using tissue samples collected in separate experiments. Two samples were taken from intact male mice, whereas the other two samples were taken 1 to 2 weeks after castration. more...

(Submitter supplied) Time series of the prostate cancer cell line LNCaP, treated for 2, 4, 6 and 8 hours with the synthetic androgen R1881. As control, the cells were cultured for 2, 4, 6 and 8 hours in the presence of the same concentration of solvent (ethanol). With this short treatment time, we aimed to identify mainly direct targets of the androgen receptor. LNCaP has a very low growth rate in steroid stripped medium and resumes growth on addition of androgens. more...

Analysis of prostate cancer (PC) xenografts collected from male mice up to 14 days after castration. The androgen receptor (AR) plays a pivotal role in the growth and survival of prostate carcinoma. Results provide insight into the role of selective adaptations of the AR pathway in PC progression.

Expression profiling of prostate cancer cell line LNCaP treated for up to 8 hours with the synthetic androgen R1881. LNCaP cells grow slowly in medium devoid of steroids but resume growth upon the addition of androgens. The study aims to identify direct targets of the androgen receptor.

(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

(Submitter supplied) Following androgen ablation treatment for advanced prostate cancer, almost all men relapse after a period of initial response to therapy, which eventually is life threatening. We have previously found that purine-rich element binding protein, PUR alpha, was significantly repressed in androgen-independent prostate cancer cell lines in comparison to an androgen-dependent line. Moreover, over-expressing PURa in androgen-independent prostate cancer cells attenuated their cell proliferation. more...

(Submitter supplied) The mouse prostate tissue exhibits strong power of regeneration, indicating the exisistence of prostate stem cells. Previously we showed that a single mouse prostate cells defined by Lin-CD44+CD133+Sca-1+CD117+ phenotype can generate a prostate after transplantation in vivo. In this study, we compared gene expression profiles of mouse prostate stem cells ( Lin-CD44+CD133+Sca-1+CD117+) and prostate non-stem cells (Lin-CD44-CD133-Sca-1-CD117-).

(Submitter supplied) Androgen deprivation is a standard of care front-line therapy for human prostate cancer, however, majority of patients will eventally develop resistance to androgen deprivation. In this study, using a human prostate cancer xenograft model -LuCaP35, we examiend the gene expression changes after castration.

NOD/SCID mice with established LuCaP35 xenografts were castrated, and tumors were isolated 4 weeks later. Androgen deprivation regresses androgen-dependent disease, but relapse often occurs in an androgen-independent manner. Results provide insight into the molecular basis of castration resistance.

(Submitter supplied) Prostate epithelial cells depend on androgens for survival and function. In early prostate cancer, besides survival, androgens also regulated tumor growth, which is exploited by androgen ablation/ blockade therapies in metastatic disease. The aim of the present study was to characterize the role of the androgen receptor pathway in prostate cancer progression and to identify potential disease markers. more...
