A comparison of competition assays performed in control shFLUC.1309 and shTSC2-transduced cells showed no significant difference in the depletion kinetics of GFP+ cells following DHX9 knockdown, in either the p53−/−Eμ-Myc or Arf−/−Eμ-Myc lymphomas (Supplementary Figure 1A and 1C). Here, DHX9 is linked to lymphoma.
