(Submitter supplied) Notch is needed for T cell development and is a common oncogenic driver in T cell acute lymphoblastic leukemia. Myc is a critical target of Notch in normal and malignant pre-T cells, but how Notch regulates Myc is unknown. Here, we identify a distal enhancer located >1 Mb 3' of human and murine Myc that binds Notch transcription complexes and physically interacts with the Myc proximal promoter. The Notch1 binding element in this region activates reporter genes in a Notch-dependent, cell context-specific fashion that requires a conserved Notch complex binding site. more...

(Submitter supplied) The main oncogenic driver in T-lymphoblastic leukemia (T-LL) is NOTCH1, which activates genes by forming chromatin-associated Notch transcription complexes. Gamma-secretase (GSI) inhibitor treatment prevents NOTCH1 nuclear localization, but most genes with NOTCH1 binding sites are insensitive to GSI. Here, we demonstrate that fewer than 10% of NOTCH1 binding sites show dynamic changes in NOTCH1 occupancy when T-LL cells are toggled between the Notch-on and –off states with GSI. more...
