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) 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.

(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...

(Submitter supplied) ETS transcription factors have recently emerged as important elements in the pathogenesis of prostate cancer (PCa). ETS gene rearrangements leading to over-expression of ETS factors, like ERG, ETV1 and ETV4, are found in about 50% of prostate tumors. While the oncogenic potential of translocated ETS has been demonstrated in several contexts, the impact of endogenously expressed ETS factors on prostate tumorigenesis has been largely overlooked. more...

(Submitter supplied) Prostate cancer is the most commonly diagnosed malignancy in the United States. While the majority of cases are cured with radiation or surgery, about 1/3 of patients will develop metastatic disease which there is no cure, and has a life expectancy of less than 5 years. Identification of antigens associated with this transition to metastatic disease is crucial for future therapies. One such antigen of interest is the SSX gene family, which are cancer/testis antigens that are associated with the epithelial to mesenchymal transition in other cancer types. more...

(Submitter supplied) NCOR2 is frequently and significantly mutated in late stage androgen deprivation therapy resistant prostate cancer (ADT-RPCa). NCOR2 has been characterized as a transcriptional corepressor and has mechanistic links to DNA methylation, but its global functions and overall contributions to PCa progression remain enigmatic. We mapped the dihydrotestosterone (DHT) dependent and independent effects of NCOR2 on the transcriptome, cistrome and DNA methylome in androgen sensitive (AS) and ADT-RPCa cells using the isogenic LNCaP and LNCaP-C4-2 (C4-2) cell models and the CWR22 xenograft model of ADT-RPCa.

(Submitter supplied) TMPRSS2 is an androgen-regulated cell surface serine protease expressed predominantly in prostate epithelium. TMPRSS2 is expressed highly in localized high-grade prostate cancers and in the majority of human prostate cancer metastasis. Through the generation of mouse models with a targeted deletion of Tmprss2, we demonstrate that the activity of this protease regulates cancer cell invasion and metastasis to distant organs. more...

(Submitter supplied) We propose that genes that control adult stem cell homeostasis in slowly turning over organs, such as prostate, control cancer fate. One such gene, KLF4, highly expressed in murine prostate stem cells, regulates their homeostasis, blocks malignant transformation and controls the self-renewal of tumor initiating cells. KLF4 loss induces molecular features of aggressive cancer and converts PIN lesions to invasive sarcomatoid carcinomas; its re-expression in vivo reverses this process. more...

(Submitter supplied) Advanced prostate cancer is a leading cause of cancer-related deaths in men, in large part due to our poor understanding of advanced castration-resistant prostate cancer (CRPC). This form of prostate cancer is uniformly lethal. Currently, the main treatments against this disease are anti-androgenic therapies; however, CRPC always develops resistance to these therapeutic modalities. Of particular interest is CRPC lacking androgen receptor (AR) activity, or AR-low CRPC. more...

(Submitter supplied) The propensity of cancer cells to transition between epithelial and mesenchymal phenotypic states is considered to be critical in metastatic processes, cancer progression, and treatment resistance. To investigate a transient epithelial-mesenchymal transition (EMT) in prostate adenocarcinoma, LNCaP cells with inducible and reversible expression of SNAI1 or SNAI2 were generated. Cells were treated with doxycycline to induce a SNAI1- or SNAI2-mediated EMT for 5 days and then subsequently removed for 3, 5, and 20 days to allow for MET. more...
