Project description:Effective therapies for metastatic osteosarcoma (OS) remain a major clinical unmet need. Targeting mRNA translation in metastatic OS represents an attractive option, as selective translation under stress supports the rapid synthesis of cytoprotective proteins that facilitate metastatic competence. We therefore assessed eukaryotic translation factors in OS, revealing high expression of eIF4A1 in metastatic OS. The eIF4A1 inhibitor, CR-1-31B, potently inhibited metastatic OS growth in vitro and reduced lung tumor burden in orthotopic mouse models. CR-1-31B synergized with the oxidative stress inducer, tert-butylhydroquinone (tBHQ), to enhance cell death under oxidative stress. Proteomic analysis revealed a subset of proteins that were upregulated by tBHQ alone, but inhibited by co-treatment of CR-1-31B, most notably the NRF2 antioxidant transcription factor, and NRF2 inactivation phenocopied CR-1-31B in blocking OS lung metastasis in vivo. Collectively, our data reveal that targeting eIF4A1 with CR-1-31B is highly effective in blocking OS metastasis by blunting the NRF2 antioxidant response.

Project description:Purpose: Osteosarcoma (OS) is the most common primary bone malignancy. OS consists of several subtypes including fibroblastic, osteoblastic and chondroblastic OS. We have developed genetically engineered mouse models of human OS that recapitulate two distinct subtypes, fibroblastic (Osx-CreLox p53-/- Rb-/-) and osteoblastic (Osx-Cre shRNA p53-/-) OS. The goal of this study was to identify transcriptional differences that distinguish the two subtypes. Methods: mRNA profiles of cell lines derived from tumours from Osx-Cre p53fl/fl Rbfl/fl (fibroblastic OS) and Osx-Cre shRNA TRE-p53.1224 pRbfl/fl (osteoblastic OS) mouse models were generated by RNA sequencing, in triplicate, using Illumina HiSeq2000. The sequence reads that passed quality filters were analyzed at the transcript level with TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the mouse genome (build mm9) and identified 12,436 transcripts in the tumours of Osx-Cre p53fl/fl Rbfl/fl and 12,074 Osx-Cre shRNA TRE-p53.1224 pRbfl/fl with the TopHat workflow. RNA-seq data confirmed stable expression of 25 known housekeeping genes. Conclusions: Our study represents a detailed analysis of OS subtype transcriptomes generated by RNA-seq technology. mRNA profiles of cell lines derived from tumours from two genetically engineered mouse models of human osteosarcoma (Osx-Cre p53fl/fl Rbfl/fl and Osx-Cre shRNA TRE-p53.1224 pRbfl/fl) were generated by deep sequencing, in triplicate, using Illumina HiSeq 2000.

Project description:Osteosarcoma in dogs is a spontaneously occurring disease with a global tumor gene expression signature indistinguishable from human pediatric tumors and clinical progression is remarkably similar. Unlike human OS, canine OS is a highly heritable disease with some large and giant dog breeds at >10x increased risk. We did a genome wide association study of osteosarcoma using the Illumina CanineHD genotyping array in three breeds: greyhound (mortality from OS = 26%), rottweiler (17%) and Irish wolfhound (IWH, 21%) and identified 33 inherited risk loci explaining 55 to 85% of phenotype variance in each breed.
