Transcriptional profiling by RNA-seq in siDDX5 Rh30 rhabdomyosarcoma cells
Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma of childhood characterized by the inability to exit the proliferative myoblast-like stage. Here, we identified the DEAD box RNA helicase 5 (DDX5) as a potential therapeutic target to inhibit alveolar rhabdomyosarcoma (ARMS) growth. We show that DDX5 is overexpressed in alveolar RMS cells, demonstrating that its depletion drastically decreases ARMS viability and slows tumor growth in xenograft models. Mechanistically, we provide evidence that DDX5 functions upstream the G9a/AKT survival signalling pathway, by modulating G9a protein stability Overall design: mRNA profiles of Rhabdomyosarcoma cells with knock-down of DDX5, three biological replicates.
