Zusammenfassung
Background: Aberrant microRNA (miRNA) expression is involved in the pathogenesis and progression of human malignancies, including embryonal tumors. Specific miRNA-levels may also serve as informative biomarkers of disease. The aim of this study was to identify specific miRNAs for different pediatric soft tissue sarcomas. Methods: We analyzed the expression of 750 miRNAs in 6 alveolar rhabdomyosarcoma (ARMS) and 6 malignant rhabdoid tumor (MRT) FFPE-tissue sections using an Illumina BeadArray. Stable expression of miR-200b and miR-200c in RMS cells was achieved by transfection of plasmids and by selection for res…
