Stemness-associated cell states are linked to chemotherapy resistance in AML. We uncovered a direct mechanistic link between expression of the stem cell transcription factor GATA2 and drug resistance. The GATA-binding protein 2 (GATA2) plays a central role in blood stem cell generation and maintenance. We find substantial intra- and inter-patient variability in GATA2 expression across AML patient samples. GATA2 expression varies by molecular subtype and has been linked to outcome. In a …
