Gene expression profile of Transgenic Adenocarcinoma of the Mouse Prostate (TRAMP)

Project description:Gene expression profile of Transgenic Adenocarcinoma of the Mouse Prostate (TRAMP) reveals murine targets for preclinical development of human prostate cancer therapy In this study, we have generated an open source TRAMP microarray dataset to identify differentially expressed genes from human prostate cancer that have concordant expression in TRAMP tumors, and thereby represent lead targets for preclinical therapy development. Affymetrix Mouse 430 2.0 chips were used for microarrays of total RNA from 9 TRAMP tumors and 9 normal prostates (ventral and dorsolateral lobes). Keywords: prostate cancer, TRAMP

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

Expression data from the dorsal and lateral lobes of the prostates of TRAMP mice treated with OSU-CG5

Project description:Cells undergoing malignant transformation often shift their cellular metabolism from primarily oxidative phosphorylation to aerobic glycolysis (the Warburg effect). Energy restriction-mimetic agents (ERMAs), such as 2-deoxyglucose and resveratrol, that target this shift in cellular metabolism have been effective in inhibiting cancer cell growth in vitro, and xenograft tumor growth in vivo. We recently developed a novel ERMA, OSU-CG5, that exhibits higher in vivo activity than previously described ERMAs. In this study, we investigated the effect of OSU-CG5 on global gene expression in the dorsal and lateral lobes of the prostate of transgenic adenocarcinoma of the mouse prostate (TRAMP) mice, and on its ability to suppress lesion progression in these mice. Intact male TRAMP mice were randomized into 2 groups and treated for 4-weeks (from age 6 to 10 weeks) with a vehicle or 100 mg/kg/day OSU-CG5 via oral gavage. At the end of the study, the urogenital tracts were collected and prostates microdissected. RNA was extracted from the dorsal and lateral lobes of the prostates from 3 mice per group, and Affymetrix microarrays were performed.

Substrate Specificity of the TRAMP Nuclear Surveillance Complexes

Project description:During nuclear surveillance in yeast, the RNA exosome functions together with the TRAMP complexes. These include the DEAH-box RNA helicase Mtr4 together with an RNA-binding protein (Air1 or Air2) and a poly(A) polymerase (Trf4 or Trf5). To better determine how RNA substrates are targeted, we analyzed protein and RNA interactions for TRAMP components. Mass spectrometry identified three distinct TRAMP complexes formed in vivo. These complexes preferentially assemble on different classes of transcripts. Unexpectedly, on many substrates, including pre-rRNAs and pre-mRNAs, binding specificity was apparently conferred by Trf4 and Trf5. Clustering of mRNAs by TRAMP association showed coenrichment for mRNAs with functionally related products, supporting the significance of surveillance in regulating gene expression. We compared binding sites of TRAMP components with multiple nuclear RNA binding proteins, revealing preferential colocalization of subsets of factors. TRF5 deletion reduced Mtr4 recruitment and increased RNA abundance for mRNAs specifically showing high Trf5 binding.

Comparison of the binding sites of TRAMP components with multiple nuclear RNA binding proteins revealed preferential colocalization of subsets of factors. On pre-mRNAs, ∆trf5 deletion caused reduced Mtr4 binding and RNA accumulation of Trf5 top targets.

F1 allele specific gene expression

Project description:By comparing mouse fibroblasts from two parental strains (Bl6 and Spretus) with fibroblasts from their first generation offspring (F1) we can detect allele specific expression of proteins. The Bl6 and Spretus lines are evolutionary distant and harbour many SNPs in their genomes which when synonomous we can detect on the protein level using mass spectrometry. By mixing SILAC labeled Bl6, Spretus and F1 offspring cell lines we can detect peptides shared between all three cell lines and also SNP peptides that are only expressed in the F1 cells and either Bl6 or Spretus cells. By comparing the abundance of the shared peptides and the SNP peptides we can quantify how much of a protein in the F1 cells that comes from the paternal or maternal allele. This data were then further compared to polysome profiling data. Azidohomoalanine labeling was used to enrich newly synthesized proteins from the three cell lines.
