Gain-of-function mutations in NOTCH1 are common in T-cell lymphoblastic leukemias making this receptor a promising target for drugs such as gamma-secretase inhibitors, which block a proteolytic cleavage required for NOTCH1 activation. However, the enthusiasm for these therapies has been tempered by ...
ORGANISM(S): Homo sapiens 
To explore the mechanisms downstream of NOTCH1 and PTEN in the control of leukemia cell growth, we performed expression profiling on NOTCH1 induced and Pten-positive T-ALL tumor cells infected with constitutively active AKT (myristoylated-AKT). Constitutive activation of AKT rescues the transcriptio...
ORGANISM(S): Mus musculus 
To investigate the underlying mechanisms mediating resistance to NOTCH inhibition in Pten-null T-ALL tumor cells we performed gene expression profiling of isogenic Pten-positive and Pten-deleted leukemia lymphoblasts after acute treatment with DBZ in vivo. This analysis revealed that, while direct N...
