Similar experiments were carried out on cell lines MV411 (Flt3ITD/MLL), THP-1 and OCI-AML3 (both NRAS)...mFLT-3 samples with co-mutations in DNMT3A, NPM1 or tMLL were very sensitive to TAK-659 (IC50 <75 nM) but much less sensitive to Ixazomib alone (IC50>100nM)...We also observed sensitivity to Ixazomib in THP-1 and OCI-AML3, while MV4-11 was sensitive to TAK-659 but relatively resistant to Ixazomib alone.
