Identification of genes differentially expressed between the prostates of PtenPC+/- mice and the prostate tumors of PtenPC+/-;Ncoa6PC-/- mice at the age of 9 months

ABSTRACT: In this study, we aimed to characterize the suppressive role of NCOA6 in prostate cancer development, uncover the underlying molecular mechanism, and identify potential therapeutic targets for treating NCOA6 loss-induced prostate cancer. Gene expression microarray analysis and RNA-Seq analysis were performed to identify differentially expressed genes influenced by NCOA6 in 22Rv1 human prostate cancer cells and mouse prostate tumors, respectively. Pathway enrichment analysis and gene set enrichment analysis were performed to identify NCOA6-regulated signaling pathways, particually the cancer-associated pathways. ChIP-Seq analysis was further performed to identify NCOA6-associated genomic regions in 22Rv1 cells. The potential direct target genes of NCOA6 were identified by combined analysis of the gene expression profiling data and ChIP-Seq data. Finally, we identified EGFR as one of the 264 NCOA6 direct target genes and deomonstrated that NCOA6 suppressed prostate cancer progression by preventing EGFR overexpression.

22Rv1 in vivo progression model

Project description:Purpose: Even in last stage of metastatic castration-resistant prostate cancer, androgen receptor (AR) signaling remains active.To derive high metastatic prostate cancer (PCa), we labeled AR-positive but castration-resistant 22Rv1 PCa cells with luciferase gene (22Rv1-Luc2) and these cells were orthotopically implanted in mouse prostate for spontaneous progression. Methods: 2 × 10^5 of luciferase-expressing 22Rv1 cells (22Rv1-Luc2) cells were implanted in the anterior prostate of nude mice. After 12-14 weeks, the host mice were necropsied and the metastases from lumbar lymph nodes and primary tumors were dissected under laminar flow. Tumor tissues were minced using sterile scalpels and further digested with Collagenase D for 1 h. The lymph node metastatic cancer cells, named 22Rv1-M1, were orthotopically reimplanted in nude mice. At 12 weeks, the secondary metastases were isolated in the lumbar lymph nodes and designated as 22Rv1-M2 cells. Suspension of 1 × 10^6 22Rv1-M2 cells in DPBS was injected into nude mice through the tail vein, and mice developed metastases (22Rv1-M3) after 6 week. This procedure was repeated once to attain the 22Rv1-M4. Results: 22Rv1-derived metastatic cell lines exhibit increased in vitro and in vivo invasion activity as the progression from 22Rv1 to M4. Transcriptomic analysis of genome-wide gene expression in the M4 tumors reveal the unique gene expression profile compared to 22Rv1 tumors. Conclusions: Transcriptomic data provide the gene network for decoding the mechanism of PCa metastasis.

Role of TNFRSF13B (CD267) in prostate cancer progression identified via genetic analysis

Project description:We performed microarray analysis using differnt prostate cancer cell lines (PC3 and 22RV1) after TNFRSF13B (CD267) knockdown. We reported that TNFRSF13B regulates cell cycle-associated genes and P53 signaling pathway in PC3 and 22RV1 cells.

RNA-Seq analysis of prostate cancer cells after morsuin treatment

Project description:We performed RNA-seq analysis using different prostate cancer cell lines (PC3 and 22Rv1) after morusin treatment. We reported that morusin regulates Akt/mTOR pathway-associated genes in PC3 and 22Rv1 cells. Morusin induces apoptosis and suppresses cell cycle progression, cell migration and invasion in PC3 and 22Rv1 cells.

Androgen receptor-independent function of FoxA1 in prostate cancer metastasis

Project description:FoxA1 has been shown critical for prostate development and prostate-specific gene expression regulation. In addition to its well-established role as an AR pioneering factor,several studies have recently revealed significant AR binding events in prostate cancer cells with FoxA1 knockdown. Furthermore, the role of FoxA1 itself in prostate cancer has not been carefully examined. Thus, it is important to understand the role of FoxA1 in prostate cancer and how it interacts with AR signaling. To address these questions, we generated engineered LNCaP cells with FoxA1 knockdown using shRNA or siRNA, 22RV1 cells with stable FoxA1 knockdown and PC3M cells with FoxA1 stable overexpression. We performed microarray analysis of these cells. We performed microarray analysis on LNCaP cells with FoxA1 knockdown using shRNA or siRNA, 22RV1 cells with stable FoxA1 knockdown and PC3M cells with FoxA1 stable overexpression
