Targeting dysregulated epigenetic and transcription factor networks in <i>KMT2A</i>-rearranged AML using iPSC models.

ABSTRACT: KMT2A chromosomal rearrangements (KMT2A-r) are frequent in pediatric acute myeloid leukemia (AML) and are associated with poor prognosis. The KMT2A gene encodes a histone lysine methyltransferase responsible for maintaining active chromatin marks (H3K4me3) at gene promoters and enhancers. KMT2A-r lead to the formation of oncogenic KMT2A fusion proteins with over 70 potential partners, disrupting normal hematopoiesis and driving leukemogenesis. Among these, KMT2A::MLLT3, a fusion of KMT2A and MLLT3, is one of the most prevalent in AML. Disruption of the epigenome is a hallmark of AML, with recurrent abnormalities in epigenetic regulators. These alterations often occur early as disease-initiating events, making epigenetic-targete
