Project description:Genome wide DNA methylation profiling of Rhabdoid tumor of the kidney, Clear cell sarcoma of the kidney, Ewing's sarcoma family of tumors and non-neoplastic kidney. The Illumina Infinium HumanMethylation 27 BeadChip was used to obtain DNA methylation profiles across approximately 27000 CpGs . Samples included 3 Rhabdoid tumor of the kidney, 3 Clear cell sarcoma of the kidney, 3 Ewing's sarcoma family of tumor and 3 non-neoplastic kidney. Bisulfite converted DNA from the 12 samples were hybridized to the Illumina Infinium HumanMethylation27 Beadchip.

Project description:The fusion oncoprotein EWS-FLI1 arises from a t(11;22)(q24;q12) chromosomal translocation and causes Ewing's Sarcoma, a malignant bone tumor. The mechanism whereby EWS-FLI1 transforms cells is unknown. Somatic, mosaic expression of human EWS-FLI1 in zebrafish from the heat shock promoter [Tg(HSP:EWS-FLI1)] caused small round blue cell tumors (SRBCTs) similar to human Ewing's sarcoma. We performed microarray studies comparing zebrafish SRBCTs to another tumor type, zebrafish malignant peripheral nerve sheath tumors (MPNSTs). The results identify a conserved set of EWS-FLI1-regulated genes,and provide insight into the pathogenesis of Ewing's Sarcoma tumors.

The results identify a conserved set of EWS-FLI1-regulated genes,and provide insight into the pathogenesis of Ewing's Sarcoma tumors. Zebrafish SRBCTs arising from somatic insertions of the EWS-FLI1 transgene were collected. MPNSTs from non-transgenic fish of the same genetic background were collected in parallel. RNA was prepared from all samples and hybridized to zebrafish-specific Affymetrix arrays.

Project description:The fusion oncoprotein EWS-FLI1 arises from a t(11;22)(q24;q12) chromosomal translocation and causes Ewing's Sarcoma, a malignant bone tumor. The mechanism whereby EWS-FLI1 transforms cells is unknown. We made germline transgenic zebrafish expressing human EWS-FLI1 under the control of the heat shock promoter. Induction of EWS-FLI1 expression causes multiple defects in embryonic development. We compared gene expression in control and transgenic EWS-FLI1 zebrafish. The results identify a conserved set of EWS-FLI1-regulated genes, and provide insight into the pathogenesis of Ewing's Sarcoma tumors.
