(Submitter supplied) Incurable metastatic castration-resistant prostate cancer (CRPC) eventually occurs after androgen deprivation treatment. It is important to understand how CRPC initiates/progress. We generated a mouse androgen-independent prostate cancer cell line (PKO) from PTEN null and Hi-Myc transgenic mice in C57BL/6 background. Here we analyzed the expression profiles of PKO cells.

(Submitter supplied) Using genetically engineered mice, overexpressing SRC-2, specifically in the prostate epithelium of PTEN heterozygous mice accelerates PTEN mutation induce tumor progression and develops a metastasis-prone cancer. Here we used ChIP-Seq analysis to identify genome-wide SRC-2 binding sites in mouse prostate.

(Submitter supplied) SRC-2 is frequently amplified or overexpressed in metastatic prostate cancer patients. In this study, we used genetically engineered mice, overexpressing SRC-2 specifically in the prostate epithelium as a mouse model to examine the role of SRC-2 in prostate tumorigenesis. Over-expression of SRC-2 in PTEN heterozygous mice accelerates PTEN mutation induced tumor progression and develops a metastasis-prone cancer. more...

(Submitter supplied) PB-Cre/Pten/Smad4 is a transgenic mouse model of metastatic prostate adenocarcinoma (PMID: 21289624). To study the transcriptomic alterations associated with castration-resistant prostate cancer (CRPC), the PB-Cre/Pten/Smad4 males with established prostate cancer were treated with surgical castration followed by enzalutamide-admixed diet. After about 4 weeks, dorsolateral prostate (DLP) lobes of treatment-naïve prostate tumors (N=2) and CRPC tumors (N=3) were harvested and extracted for RNA purification and microarray profiling. more...

(Submitter supplied) PI3K (phosphoinositide 3-kinase)/AKT and RAS/MAPK (mitogen-activated protein kinase) pathway coactivation in the prostate epithelium promotes both epithelial–mesenchymal transition (EMT) and metastatic castration-resistant prostate cancer (mCRPC), which is currently incurable. To study the dynamic regulation of the EMT process, we developed novel genetically defined cellular and in vivo model systems from which epithelial, EMT and mesenchymal-like tumor cells with Pten deletion and Kras activation can be isolated. more...

(Submitter supplied) Androgen-deprivation therapy is a standard treatment for advanced prostate cancer. However, most patients eventually acquire resistance and progress to castration-resistant prostate cancer (CRPC). In this study, we established new CRPC cell lines, AILNCaP14 and AILNCaP15, from LNCaP cells under androgen-deprived conditions. Unlike most pre-existing CRPC cell lines, both cell lines expressed higher levels of androgen receptor (AR) and prostate-specific antigen (PSA) than parental LNCaP cells. more...

(Submitter supplied) Androgen receptor (AR) pathway inhibition remains the cornerstone for first- and second-line prostate cancer therapies. Although AR signaling inhibitors, such as enzalutamide and abiraterone extend survival in recurrent and castration-resistant prostate cancer (CRPC), durable and complete responses are rare. Resistance mechanisms employed by metastatic CRPC include amplification of AR and AR splice variants in AR-positive CRPC (ARPC) and conversion to AR-null phenotypes, such as double-negative prostate cancer (DNPC) and small cell or neuroendocrine prostate cancer (SCNPC). more...

(Submitter supplied) In order to define the genes responsible for the growth and survival of a human castration-resistant prostate cancer cell line, a short term (doxycycline inducible) knockdown system was developed and utilized. Three independent 22Rv1 cell isolates were derived for each of the following doxycycline-inducible shRNAs (shGFP, shAR3, and shVav3) (AR3 = AR-V7). The cells were grown in androgen depleted conditions, plus or minus doxycycline, for three days. more...

(Submitter supplied) We report RNA sequencing data on serial biopsies of prostate cancer VCaP xenografts as the tumors pass from androgen-sensitivity (Pre-Cx), to castration resistance (CRPC, castration resistant prostate cancer), onto resistance to dual therapy with abiraterone plus enzalutamide (AER). From comparison of these RNAseq data sets, we were able to determine differentially expressed genes between the AER/CRPC and Pre-Cx states that could mediate resistance to androgen deprivation therapies.

The 22Rv1 derivatives were generated as following: Parental 22Rv1 (Rv1-WT) were transduced with a lentivirus expressing luciferase, yielding the derivative Rv1-Luc. 22Rv1 cells with a double knockout of CDK8 and CDK19 (Rv1-dKO) were made via CRISPR/Cas9. more...
