  • Integrative analysis of DNA sequence, copy number and mRNA expression in 207 samples encompassing seven major subtypes
  • Detailed map of molecular alterations across diverse sarcoma subtypes
  • PIK3CA is mutated in 18% of myxoid and round-cell liposarcomas and associated with Akt activation and poor clinical outcome
  • NF1 is mutated and deleted in myxofibrosarcomas and pleomorphic liposarcomas
  • shRNA knockdown of genes amplified in dedifferentiated liposarcoma idenifies genes involved in cell proliferation
