| Title |
Expression data from isogenic Pten WT or KO mouse T-ALLs treated with DBZ or DMSO |
| Organism |
Mus musculus |
| Experiment type |
Expression profiling by array
|
| Summary |
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 NOTCH1 target genes (such as Hes1, Dtx1, PtcrA, HeyL and Notch3) are effectively downregulated in both Pten-positive and Pten-deleted tumors, genetic ablation of Pten elicits a global reversal of much of the transcriptional effects of NOTCH inhibition.
