ProteomicsIdentification of ANXA1 as A Novel Upstream Negative Regulator of Notch1 Function in AML
Abnormal Notch1 expression has an important role in tumorigenesis. However, upstream control mechanisms for Notch1 are still insufficiently understood. Acute myeloid leukemia (AML) is one of the most common and lethal blood malignancies with limited possibilities for treatment. Thus, new therapeutic...

TranscriptomicsTranscription profiling by array of human T-ALL cells purified from the BM of mice treated with anti-Notch1 or control mAbs
We generated PDTALL19 xenograft by intravenously injection of primary T-ALL cells from BM of a newly diagnosed ALL pediatric patient in NOD/SCID mice. To test the effect of Notch1 blockade on PDTALL19 cells engraftment, mice were treated with anti-human Notch1 mAb OMP-52M51 (OncoMed Pharmaceuticals ...

TranscriptomicsNOTCH1 activation in breast cancer confers sensitivity to inhibition of SUMOylation
Breast cancer is genetically heterogeneous, and recent studies have underlined a prominent contribution of epigenetics to the development of this disease. To uncover new synthetic lethalities with known breast cancer oncogenes, we screened an epigenome-focused short hairpin RNA library on a panel...

TranscriptomicsAnalysis of gene expression in wildtype and Notch1 mutant retinal cells by single cell profiling
Loss of Notch1 in retinal progenitor cells (RPCs) during postnatal retinal development results in the overproduction of rod photoreceptors at the expense of interneurons and glia. To examine the molecular underpinnings of this observation, microarray analysis of singla retinal cells from wildtype (W...

TranscriptomicsSite-specific methylation of Notch1 controls the amplitude and duration of the Notch1 response
Physiologically, Notch signal transduction plays a pivotal role in differentiation; pathologically, Notch signaling contributes to the development of cancer. Transcriptional activation of Notch target genes involves cleavage of the Notch receptor in response to ligand binding, production of the Notc...

TranscriptomicsTranscription profiling of human time points after induction of Notch1-IC, Notch2-IC or EBNA2 in EREB2-5 cells - detection of Notch1-IC, Notch2-IC and EBNA2 target genes in human B cells
Notch1-IC, Notch2-IC or EBNA2 have been induced in a conditionally immortalized human B cell line (EREB2-5) in order to identify similar and unique target genes in B cells. CAT was used as a control. Experiment Overall Design: RNA was isolated at different time points after induction of Notch1-IC, N...

GenomicsNotch1-driven epigenetic changes in a mouse model of T cell Acute Lymphoblastic Leukemia (T-ALL)
T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we used a mouse model of T-ALL through the overexpression of the intarcellular transcriptionally active part of Notch1 (N1-IC). This model fait...

TranscriptomicsExpression data from Hes1 conditional knock-out NOTCH1-induced leukemias
To formally address the biological activity of Hes1 in vivo, we tested the interaction between oncogenic NOTCH1 and acute Hes1 loss in a retroviral-transduction bone marrow transplantation model of NOTCH-induced T-ALL Forced expression of activated NOTCH1 in this model typically results in full leuk...

TranscriptomicsNotch1 dose modulates endothelial gene expression
Purpose: To use RNA-Seq analysis of endothelial cell in various Notch1 alllels in order to determine transcrptional differencesas a consequence of Notch dose. Methods: Using a FACS sorting we generated high-throughput RNA-SEQ data of endothelials in various Notch1 alleles during development Results...

GenomicsNOTCH1/RBPJ complexes drive target gene expression through dynamic interactions with super-enhancers
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...
