Identification of serum microRNAs associated with prostate cancer in a mouse model of disease

ABSTRACT: There is an urgent need for new biomarkers to enhance the clinical management of prostate cancer. Circulating microRNAs (miRNAs) are emerging as useful non-invasive markers of disease. The objective of this study was to test the utility of a mouse model of prostate cancer as a tool to discover serum miRNAs that could be applied in a clinical setting. Global miRNA profiling using microarrays identified 46 miRNAs at differential levels in the serum of TRansgenic Adenocarcinoma of Mouse Prostate (TRAMP) mice compared to their wild-type littermates. Total RNA extracted from the serum of 9 mice with advanced disease was pooled into 3 groups (TRAMP serum RNA 1, 2 and 3). Serum RNA from age-matched wild-type littermates, pooled as above, served as the control set.

An Immune and Inflammation Signature in Prostate Tumors of Smokers (part 1)

Project description:Current smokers develop metastatic prostate cancer more frequently than nonsmokers, suggesting that a tobacco-derived factor induces metastasis. To identify smoking-induced alterations in human prostate tumors, we analyzed gene and protein expression of tumors from current, past, and never smokers and observed distinct molecular alterations in current smokers. Specifically, an immune and inflammation signature was identified in prostate tumors of current smokers that was either attenuated or absent in past and never smokers. Key characteristics of this signature included augmented immunoglobulin expression by tumor-infiltrating B cells, NF-kB activation, and increased interleukin-8 in tumor and blood. In an alternate approach to characterize smoking-induced oncogenic alterations, we explored the effects of nicotine in prostate cancer cells and prostate cancer-prone TRAMP mice. These experiments showed that nicotine increases both invasiveness of human prostate cancer cells and metastasis in tumor-bearing TRAMP mice, indicating that nicotine can induce a phenotype that resembles the epidemiology of smoking-associated prostate cancer progression. In summary, we describe distinct oncogenic alterations in prostate tumors from current smokers and show that nicotine can enhance prostate cancer metastasis. Prostate tissues of cancer patients were selected for RNA extraction and hybridization on Affymetrix microarrays. Gene expression profiles of current, past and never smokers were compared.

Interception targets of Angelica Gigas Nakai root extract vs. pyranocoumarins in prostate early lesions and neuroendocrine carcinomas in TRAMP mice

Project description:We reported efficacy of Angelica gigas Nakai (AGN) root ethanol extract and equimolar decursin (D)/decursinol angelate (DA) through daily gavage starting at 8 weeks of age (WOA) to male transgenic adenocarcinoma of mouse prostate (TRAMP) mice such that these modalities suppressed precancerous epithelial lesions in their dorsolateral prostate (DLP) to similar extent, but AGN extract was better than the D/DA mixture at promoting the survival of mice bearing prostate neuroendocrine carcinomas (NECa) to 28 WOA (Tang et al, Cancer Prev Res 2015). Here, we compared by microarray hybridization the mRNA levels in pooled DLP tissues and individual NECa to characterize potential molecular targets of AGN extract and D/DA. Clustering and principal component analyses supported distinct gene expression profiles of TRAMP DLP vs. NECa. Pathway Enrichment, Gene Ontology and Ingenuity Pathway Analyses of differential genes indicated that AGN and D/DA affected chiefly processes of lipid and mitochondrial energy metabolism and oxidation-reduction in TRAMP DLP, while AGN affected neuronal signaling, immune systems and cell cycling in NECa. Protein-Protein Interaction Network analysis predicted and reverse transcription-PCR verified multiple hub genes common in the DLP of AGN- and D/DA-treated TRAMP mice at 28 WOA and select hub genes attributable to the non-D/DA AGN components. The vast majority of hub genes in the AGN-treated NECa differed from those in TRAMP DLP. In summary, the transcriptomic approach illuminated vastly different signaling pathways and networks, cellular processes and hub genes of two TRAMP prostate malignancy lineages and their associations with the interception efficacy of AGN and D/DA.

Adipose tissue from metabolic syndrome mice induces an aberrant miRNA signature highly relevant in prostate cancer development

Project description:We developed a MeS-like disease model using C57BL/6J mice chronically fed with high fat diet (HFD) that were inoculated with TRAMP-C1 prostate cancer (PCa) cells to investigate the interaction between white adipose tissue (WAT) and PCa cells through miRNAs, in MeS mice. In this dataset, we include the expression data obtained from co-culture medium between TRAMP-C1 cells with HFD-gonadal WAT (gWAT) versus TRAMP-C1 cells with CD-gWAT. For differential expression analysis we used the Rank Product Method.

Gene expression analysis of prostate tumors arisen in TRAMP mice in which mast cells are pharmacologically stabilized or genetically ablated.

Project description:Analysis of gene expression of prostate tumors arisen in TRAMP mice in which mast cells are pharmacologically stabilized or genetically ablated.The hypothesis tested in the present study was that mast cells inhibition or absence impacted prostate tumor development and histotype. Results demonstrate that prostate tumors arisen in TRAMP mice in which mast cells are pharmacologically stabilized or genetically ablated have a neuroendocrine signature. Total RNA obtained from prostate tumors from 24 wks old TRAMP mice chronically treated with sodium chromoglycate (cromolyn) since 8 wks of age, and from 24 wks old TRAMP KitW-sh mice, compared to untreated 30 wks old TRAMP mice and to non tumoral prostates

Genetic deletion of osteopontin in TRAMP mice enhances the growth of aggressive prostate cancer with feature of human neuroendocrine tumors

Project description:Osteopontin (OPN) is a secreted glycoprotein, belonging to the non-structural extracellular matrix (ECM), and its over expression in human prostate cancer cells has been associated with disease progression, androgen independence and metastases. Nevertheless the pathophysiology of OPN in prostate tumorigenesis has never been studied. We crossed TRansgenic Adenocarcinoma of the Mouse Prostate (TRAMP) mice with OPN deficient (OPN-/-) mice and followed tumor onset and progression in these double mutants. Ultrasound examination detected the early onset of a spherical homogeneous tumor in about 60% of OPN-/- TRAMP mice that seldom occurs in parental TRAMP mice. Histology and immunohistochemistry characterized these tumors for being Tag positive but negative for AR, highly proliferative and endowed of neuroendocrine (NE) features. Gene expression profiling showed up-regulation of genes involved in tumor progression, cell cycle and neuronal differentiation in OPN-deficient versus -sufficient TRAMP tumors. Down-regulated genes included key genes of TGFï?¢ pathway, and a role for TGFï?¢ in NE differentiation of prostate cancer was also confirmed at the protein level. Furthermore, NE genes and particularly those characterizing early prostatic lesions of OPN-deficient mice were found to correlate with those of human NE tumours. These data underscore a novel role of OPN at early stages of prostate cancer growth, protecting against the development of aggressive NE tumors. Total RNA obtained from prostate tumors from 18 and 30 weeks old TRAMP mice, compared to RNA extracted from prostate tumors and prostate tissue from Osteopontin-deleted TRAMP mice
