  Notwithstanding advances over the last decade in the comprehension of the molecular biology of Ewing sarcoma (ES), we still lack an understanding of critical issues, especially those regarding its genesis. In particular, little effort has been devoted to characterization of the proteic component of the mechanisms and pathways deployed by the activation of the fusion protein resulting from chromosomal translocation. We decided to investigate the proteic alterations of an ES cell line bearing a representative fusion protein. The combination of RNA interference of EWSFLI1 in the ES cell line TC-71, a proteomic analysis by 2-D electrophoresis and subsequent mass-spectrometry identification, and a global overrepresentation study detected changes in more than 500 spots. Forty-three proteins were identified as being significantly differentially abundant. As expected, we found and validated c.. View More»
