Gene expression profiling of mouse NOTCH1-induced tumors following in vivo treatment with gamma-secretase Inhibitor

ABSTRACT: NOTCH1 is a transcription factor involved in T-cell development and mutations that occur in NOTCH1 gene affects more than 60% of patients affected by T-cell acute lymphoblastic leukemia (T-ALL). In order to identify genes and pathways regulated following NOTCH1 inhibition in T-ALL, murine NOTCH1-induced T-cell leukemia were treated with a NOTCH1 inhibitor (DBZ, Dibenzazepine). Tumors were established in irradiated C57BL/6 mice injected with lineage negative progenitors cells transduced with a mutated NOTCH1 allele (HD-ΔPEST NOTCH1). Mice were treated three times, 8 hours apart, with vehicle only (DMSO) or DBZ (5mg/Kg). Total RNA was extracted from tumor samples (spleens of sick mice) and hybridized on Agilent SurePrint G3 Mouse GE 8x60K arrays. Each sample was derived from a different mou
