Project description:A Sleeping Beauty (SB) transposon forward genetic screen was performed to identify the genes that promote osteosarcoma (OS) development and metastasis. Mutagenesis induced OS in wild type mice and accelerated it on a Trp53 deficient background. Analysis of tumors demonstrated that Trp53 deficiency is correlated with genomic instability, which was virtually absent in tumors induced by SB mutagenesis alone. Metastases developed in a subset of animals and in nearly all cases were clonal related to primary tumors. Over 200 candidate genes were identified, many of which are altered in human cancers including OS. Signaling pathways enriched for candidate genes were also identified and a subset of these pathways and genes were functionally validated and represent new targets for OS treatment. Bisulphite converted DNA from the 21 diagnosis osteosarcoma patients and 3 hOB cell line replicates were hybridised to the Illumina Infinium 450K Human Methylation Beadchip.

Project description:Three normal human osteoblast samples, acquired from PromoCell, were used as controls to compare to RNA-seq data from prepublished osteosarcoma samples (submitted to the European Bioinformatics Institute; EGAS00001000263) for the purpose of evaluating expression levels of genes identified as common insertions sites in a Sleeping Beauty screen of osteosarcomas in mice.

Three normal human osteoblast samples (pellet form in RNAlater) were acquired from PromoCell (Heidelberg, Germany), and RNA was isolated from them immediately upon receipt.
Project description:Thymic lymphomas were generated by inducing Sleeping Beauty transposon mutagenesis at different stages of T-cell development. This dataset includes exon array results from 14 tumor samples from two different Sleeping Beauty models of T-ALL (7 Vav-SB and 7 CD4-SB samples).
Project description:We extracted RNA of 39 mouse tissue of various genotypes and performed expression microarrays. Subsequently a screen was conducted using the Sleeping Beauty (SB) transposon to identify breast cancer candidate genes. 39 mouse samples expression data.
