Here we modeled T-ALL resistance to Notch inhibition, identifying M-bM-^@M-^XpersisterM-bM-^@M-^Y cells that readily expand in the presence of gamma secretase inhibitor (GSI) and the absence of Notch signaling. Rare persister cells are already present in naM-CM-/ve T-ALL populations, and the reversi...

Cyclin D3 is critical hematopoiesis and loss of cyclin D3 leads to resistance to transformation of bone marrow progenitors by Notch1-IC. We used a small molecule targeting cyclin D3:CDK4/6 activity to study whether its inhibition is an effective therapeutic strategy. We analyzed T-ALL lines in vitro...

The oncogenic transcription factor TAL1/SCL is aberrantly overexpressed in over 40% of cases of T-cell acute lymphoblastic leukemia (T-ALL), emphasizing the importance of the TAL1-regulated transcriptional program in the molecular pathogenesis of T-ALL. Here we identify the core transcriptional regu...
