Project description:The 1q gain is related to poor survival, and to a profile of cell cycle deregulation in Ewing's Sarcoma (ES). Tumor samples with 1q gain overexpress the gene DTL. We have silenced DTL in three ES cell lines in order to compare the differential expression pattern produced with the differential expression pattern which characterizes 1q gained-tumors.
Project description:The 1q gain is related to poor survival, and to a profile of cell cycle deregulation in Ewing's Sarcoma (ES). Tumor samples with 1q gain overexpress the gene DTL. We have silenced DTL in three ES cell lines in order to compare the differential expression pattern produced with the differential expression pattern which characterizes 1q gained-tumors. We silenced DTL in three ES cell lines with two different shRNA constructions by means of lentiviral transduction. pLKO.1-non-targeting control was transduced in the control samples. RNA was extracted and hybridized with Affymetrix expression microarrays.
Project description:Background: Gain and/or amplification of chromosome 1q are frequently found in Multiple Myeloma (MM). The number of 1q copies correlates with a poor prognosis. The aim of this work is to study the impact on the clinical outcome and the trascriptomic changes induced by Gain1q (3 copies of 1q, 3X) and amplification 1q (Amp1q, ≥4 copies of 1q, 4X) in MM patients enrolled in the CoMMpass study (NCT145429). Methods: Fluorescence in situ hybridization (FISH) in CD138+ purified bone marrow plasma cells was centralized and performed at baseline. The cut-off level for Gain1q was 10% of nuclei with ≥3 copies of 1q (3X), while Amp1q was defined as ≥ 20% of nuclei with ≥4 copies of 1q (4X). Transcriptome data from patients were used to find differentially expressed genes (DEGs) in gain (3X) and amp1q (4X) patients.

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.
