T-ALL patients with NOTCH1 mutations show a highly distinctive gene expression profile indicative of a pluripotent state, which is defined by the ability of malignant T-cells to repopulate a host in vivo.46 The NOTCH1 pathway exerts this tumor-initiating function by activating a large number of embryonic developmental genes (e.g., HES1 or HES5), which orchestrate the induction of undifferentiated cell-fate commitment, along with many pro-metabolic gene programs.45,46 The NOTCH1-dependent induction of MYC oncogene activity underlies both the sustained anabolic activity and the cel- cycle independence of T-ALL lymphoblasts. Notably, NOTCH1 mutations in T-ALL are always associated with a specific subtype of T-ALL, characterized by high expression (on average more than tenfold) of the TF TAL1, which is a major transcriptional regulator of the pro-pluripotent Creb/ATF2 (cyclic AMP response element-binding protein/activating transcription factor 2) transcriptional program.48 In T-cell acute lymphoblastic leukemia (T-ALL), which is characterized by high TAL1 expression, an excess of late plasma membrane-tethered NOTCH1 can induce sustained signaling in the absence of ligand-receptor interaction.4 As a result of aberrant NOTCH1 signaling, MYC activity is also high. Specifically, NOTCH1-signaling leads to MYC overexpression by 2 mechanisms, modulated by FBXW7. The first mechanism consists of stabilization of MYC proteins in T-ALL cells because of reduced polyubiquitination by FBXW7. The second mechanism consists of constitutive recruitment of FBXW7-targeted E2-ubiquitin conjugating enzyme to the NICHD1/ICN1 domain. As a result, FBXW7 prevents degradation of NOTCH1 in T-ALL cells.
This widely accepted view of how NOTCH can act in neoplastic cells has recently been challenged by the findings that, in an Eμ-MYC mouse model of T-ALL, sustained NOTCH signaling promotes the differentiation of residual normal T-cells into macrophages.
