(Submitter supplied) Purpose: Patients with locally advanced prostate cancer after radical prostatectomy are candidates for secondary therapy. However, this higher risk population is heterogeneous. Many cases do not metastasize even when conservatively managed. Given the limited specificity of pathological features to predict metastasis, newer risk prediction models are needed. We report a validation study of a genomic classifier that predicts metastasis after radical prostatectomy in a high risk population. more...

(Submitter supplied) Neuroendocrine prostate cancer (NEPC) is proliferative, invasive, and untreatable. Its molecular pathogenesis remains poorly understood but appears to require TP53 and RB1 aberration. In this study we modeled the development of NEPC from conventional prostatic adenocarcinoma using a unique patient-derived xenograft and identified up-regulation of the placental gene PEG10. We found that the androgen receptor and the E2F/RB pathway dynamically regulate distinct post-transcriptional and post-translational isoforms of PEG10 at different stages of NEPC development. more...

(Submitter supplied) Purpose: Clinicopathologic features and biochemical recurrence are sensitive, but not specific, predictors of metastatic disease and lethal prostate cancer. We hypothesize that a genomic expression signature detected in the primary tumor represents true biological potential of aggressive disease and provides improved prediction of early prostate cancer metastasis. Methods: A nested case-control design was used to select 639 patients from the Mayo Clinic tumor registry that underwent radical prostatectomy between 1987 and 2001. more...

(Submitter supplied) Treatment-emergent neuroendocrine prostate cancer (t-NEPC) is a lethal subtype of advanced prostate cancer that develops via NE transdifferentiation of prostate adenocarcinomas in response to androgen receptor (AR)-inhibition therapy. Study of t-NEPC has been hampered by a lack of clinically relevant models. We previously established a unique and first-in-field patient-derived xenograft (PDX) model of adenocarcinoma (LTL331)-to-NEPC (LTL331R) transdifferentiation. more...

(Submitter supplied) Neuroendocrine prostate cancer (NEPC) is a lethal subtype of prostate cancer (PCa) with hyperchromatic nuclei being a distinguishing histopathological feature. Here we show that, underlying this distinct nuclear structure, heterochromatin related genes are significantly enriched in NEPC. Among them, heterochromatin protein 1α (HP1α) expression is increased early in NE transdifferentiation and is consistently elevated in clinical NEPC samples. more...

(Submitter supplied) To determine the underlying mechanism of ONECUT2 in prostate cancer hypoxia, we conducted a series of RNA-Seq and ChIP-Seq experiments in LNCaP and PC3 cells under normoxia and hypoxia conditions. We did RNA-Seq in LNCaP cells with or without OC2 overexpression and in PC3 cells with or without OC2 knockdown. We used anti-Flag antibody to perform the ChIP-Seq experiment in PC3 cells with Flag and OC2 fusion protein overexpression. more...

(Submitter supplied) Neuroendocrine prostate cancer (NEPC) is rare historically but may be increasingin prevalence as patients potentially develop resistance to contemporary anti-androgen treatment through a neuroendocrine phenotype. Diagnosis can be straightforward when classic morphological features are accompanied by a prototypical immunohistochemistry profile, however there is increasing recognition of disease heterogeneity and hybrid phenotypes. more...

(Submitter supplied) Serine Peptidase Inhibitor, Kazal type 1 (SPINK1) overexpression represents the second-largest prostate cancer (PCa) subtype associated with increased risk of biochemical recurrence and poor prognosis. To determine the pathways regulated by SPINK1 in 22RV1 prostate cancer cells, we performed shRNA mediated knockdown of SPINK1 using lentiviral constructs. Scrambled shRNA was used as a control. pGIPZ constructs against SPINK1 (shSPINK1-1, shSPINK1-2, shSPINK1-3) and control shScrambled construct were purchased from Dharmacon.

(Submitter supplied) As part of functional characterization of neuroblastoma associated lncRNA HOXD-AS1, we performed its knock-down in neuroblastoma cell line SH-SY5Y, which resulted in modulation of expression levels of a set of genes involved in angiogenesis and inflammation, the hallmarks of metastatic cancer.

(Submitter supplied) Prostate adenocarcinoma (AdPC) cells can undergo lineage switching to neuroendocrine cells and develop into therapy-resistant neuroendocrine prostate cancer (NEPC). While genomic/epigenetic alterations are shown to induce neuroendocrine differentiation via an intermediate stem-like state, RNA splicing factor SRRM4 can transform AdPC cells into NEPC xenografts through a direct neuroendocrine transdifferentiation mechanism. more...

(Submitter supplied) We identified 27 long noncoding RNAs with differential expression (DE-lncRNAs) between prostate cancer metastases and corresponding primary tumors, suggesting that they are metastatic castration resistant prostate cancer (mCRPC)-specific lncRNAs. To assess androgen regulation of the DE-lncRNAs, we investigated their expression in LNCaP and VCaP cells induced with dihydrotestosterone (DHT) as well as in androgen receptor (AR)-silenced cells by using RNA-sequencing.

(Submitter supplied) Neuroendocrine prostate cancer (NEPC) is the most virulent subtype. Currently, there is an urgent need to identify new biomarkers and therapeutic targets in NEPC. The splicing factor SRRM4 was previously demonstrated to be highly expressed in NEPC, to promote expression of genes linked to neuroendocrine differentiation and cancer progression, and to promote alternate splicing of genes, including REST. more...

(Submitter supplied) MYCN amplification and overexpression are common in neuroendocrine prostate cancer (NEPC). However, the impact of aberrant N-Myc expression in prostate tumorigenesis and the cellular origin of NEPC have not been established. We define N-Myc and activated AKT1 as oncogenic components sufficient to transform human prostate epithelial cells to prostate adenocarcinoma and NEPC including the small cell prostate carcinoma (SCPC) variant with phenotypic and molecular features of aggressive, late-stage human disease. more...

(Submitter supplied) Transcriptional regulator REST plays a key role in repressing neuronal specific genes in prostate cancer and other non-neuronal tissues. Moreover, loss of REST is observed in neuroendocrine prostate tumors. Here, we use ChIP-seq analysis to study genome–wide REST occupied regions in the prostate cancer cell line, LNCaP. REST occupied regions were then correlated to gene expression changes occurring between prostate adenocarcinoma and neuroendocrine prostate tumors in vivo.
