Divergent medulloblastoma chromatin states disclose KDM2B as a selective dependency

Abstract Medulloblastoma is a biologically heterogeneous childhood cerebellar tumor harboring frequent chromatin-modifying gene alterations. How these alterations promote transcriptional programs governing malignancy remains poorly defined. To address this knowledge gap, we evalu...

MBNL1 hijacks a structured single-stranded distal DNA element to sustain FLT3 expression in KMT2A-rearranged leukemias

The molecular mechanisms by which KMT2A-rearranged (KMT2A-r) leukemias maintain the oncogenic FLT3 expression remain largely unclear, limiting therapeutic opportunities. Here, we identify the RNA binding protein MBNL1 as an unexpected positive regulator of FLT3 by DepMap dataset...
