Morphoproteomic Profiling of the Mammalian Target of Rapamycin (mTOR) Signaling Pathway in Desmoplastic Small Round Cell Tumor (EWS/WT1) Ewing’s Sarcoma (EWS/FLI1) and Wilms’ Tumor(WT1)

摘要

BackgroundDesmoplastic small round cell tumor (DSRCT) is a rare sarcoma in adolescents and young adults. The hallmark of this disease is a EWS-WT1 translocation resulting from apposition of the Ewing’s sarcoma (EWS) gene with the Wilms’ tumor (WT1) gene. We performed morphoproteomic profiling of DSRCT (EWS-WT1), Ewing’s sarcoma (EWS-FLI1) and Wilms’ tumor (WT1) to better understand the signaling pathways for selecting future targeted therapies.
