Project description:Affymetrix exon array data were generated from total RNA that was isolated from localized Ewing sarcoma biopsy specimens. Expression of transcript summarized data was compared to data generated from normal stem cells and normal adult tissues. Total RNA was extracted from 32 archived tumor biopsy specimens obtained from patients with localized Ewing sarcoma. Samples were analyzed by Affymetrix exon arrays using standard procedures. Data were compared to human neural crest and mesenchymal stem cells (in triplicate: GSE21511) as well as to 33 normal adult tissues (Affymetrix tissue controls; 11 tissues in triplicate: cel files obtained from: http://www.affymetrix.com/support/technical/sample_data/exon_array_data.affx). Normalization was achieved by RMA using Parkek Genomics Suite
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Affymetrix exon array data were generated from total RNA that was isolated from localized Ewing sarcoma biopsy specimens. Expression of transcript summarized data was compared to data generated from normal stem cells and normal adult tissues.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
Project description:STAG2 is a member of cohesin complex and its gene is one of the most recurrently mutated in human cancer including in Ewing sarcoma. Here, we investigated STAG2 function in the context of Ewing sarcoma and performed transcriptome profiling of a panel of 15 WT and 15 mutated STAG2 established Ewing sarcoma cell lines.
Project description:This SuperSeries is composed of the following subset Series: GSE30513: MicroRNA expression profiling of Ewing sarcoma cancer stem cells GSE31144: MicroRNA expression profiling of Ewing sarcoma cell lines upon TARBP2 depletion GSE31145: MicroRNA expression profiling of Ewing sarcoma spheres vs. adherent cells Refer to individual Series
