To identify targets of MBNL1 specifically in MLL-rearranged leukemias, we performed RNA-Seq in two MLL-rearranged cell lines (MOLM13, MV4;11) with knockdown of MBNL1 and compared these results to those from the Leucegene consortium dataset of MLL-rearranged patient AML bone marrow samples44. The gene discussed is KMT2A; the disease is acute myeloid leukemia.
