NOTCH-mutations drive immune-escape mechanisms in B cell malignancies

ABSTRACT: Here we provide access to MCL expression data that were used for interrogating the molecular functions of NOTCH1 and NOTCH2, which are two of the most commonly mutated genes in CLL and MCL and associated with a poor clinical outcome. The mechanisms underlying how NOTCH1 contributes to disease progression, resistance to treatment and RichterÃ¢Â€Â™s transformation remain largely unknown. The main goal of this study is to compare the gene expression profile of primary MCL cells transduced with the intracellular part of NOTCH1 or NOTCH2 lacking of the PEST domain vs cells transduced with an empty vector.

Gene expression profile of primary CLL cells transduced with a mutated form on NOTCH1 following IgM stimulation

Project description:In CLL, NOTCH1 is the most commonly mutated gene at diagnosis and it is associated with a poor outcome. The mechanisms underlying how NOTCH1 contributes to disease progression, resistance to treatment and Richter’s transformation remain largely unknown. Data suggests a link between BCR activation and NOTCH1 signalling so the main goal of this study is to compare the gene expression profile of primary CLL cells transduced with the intracellular part of NOTCH1 lacking of the PEST domain vs cells transduced with an empty vector following IgM stimulation.

Histone H3 lysine 27 acetylation (H3K27ac) profile of primary CLL cells transduced with a retrovirus expressing mutated NOTCH1

Project description:In chronic lymphocytic leukemia (CLL), NOTCH1 is the most commonly mutated gene at diagnosis and it is associated with a poor outcome. The mechanisms underlying how NOTCH1 contributes to disease progression, resistance to treatment and Richter’s transformation remain largely unknown. The main goal of this study is to compare the chromatin activation profile of primary CLL cells transduced with the intracellular part of NOTCH1 lacking of the PEST domain vs. cells transduced with an empty vector. Additionally, patients with the Trisomy 12 abnormality are included in this study to clarify the role of the mutations in this specific sub-group of CLL patients that are strongly associated with NOTCH1 mutations.

Histone variant H2A.Z deposition and acetylation directs the canonical Notch signaling response

Project description:The study deals with the elucidation of potential interaction partners of the intracellular domain of the transmembrane receptor Notch1, termed NICD. The NICD is released from the cytoplasmic tail of the Notch receptor by gamma-secretase treatment and translocated as a transcription factor to the nucleus. Here, virally transduced recombinant NICD constructs (wild-type and deltaEP hyperactive mutant) were employed for AP-MS with the aim of identifying novel NICD interactors in a murine T cell leukemia cell line.

Identification of Notch targets in human endothelial cells

Project description:Human umbilical vein endothelial cells (HUVECs) were transduced with either MIY-N1IC (Notch1 intracellular domain) or MIY vector control. The cells were sorted for YFP, and RNA was extracted using Trizol (Invitrogen) and analyzed by the Affymetrix Human Genome U133 Plus 2.0 Array. Results were analyzed using the GCRMA algorithm to identify genes with a minimum of 2-fold induction or reduction. This global gene expression study was used to identify Notch targets in the endothelium. Expression profiling of primary HUVECs transduced with N1IC. HUVEC primary cells were isolated, transduced with N1IC or vector (MIY) control in three biological replicates, and evaluated on Affymetrix Human Genome U133 Plus 2.0 arrays.

Comprehensive gene expression analysis in liver tissue following forced activation of Notch1 and Notch2 signaling.

Project description:We compared the effects of Notch1 and Notch2 signaling induced by AAV8-mediated forced expression of Notch1 intracellular domain (NICD1) and Notch2 intracellular domain (NICD2), respectively, in the liver. Eight-week-old wild-type male mice were injected intraperitoneally with an NICD1- and/or NICD2-overexpressing AAV8 vector. Efficient AAV8-mediated gene transfer was confirmed by co-expressed green fluorescent protein (GFP) fluorescence in hepatocytes. A comprehensive gene expression analysis using DNA microarray indicated that the expression levels of 1704 and 1325 genes were altered by overexpressing NICD1 and NICD2, respectively, compared with the control group expressing only GFP.

Notch2 controls non-autonomous Wnt-signalling in chronic lymphocytic leukaemia

Project description:The Wnt-signalling pathway is one of the core de-regulated pathways in chronic lymphocytic leukemia (CLL), activated in a subset of patients by somatic coding mutations. Here we describe an alternative mechanism of Wnt-activation in malignant B cells, mediated by Notch2 activity in mesenchymal stromal cells (MSC) in the tumor microenvironment. We identified that tumor cells specifically induce and activate Notch2 in MSCs. Notch2 orchestrates the expression of target genes essential for the activation of canonical Wnt-signaling in CLL cells. Mechanistically, stromal Notch2 mediates the stabilization of â-catenin by inhibiting the activation of Gsk3-â in malignant B cells. Pharmacological inhibition of the Wnt-pathway mitigates microenvironment-mediated survival of malignant B cells in vitro. Similarly, inhibition of Notch-signaling impaired survival of CLL cells and disease engraftment in a PDX mouse model. Notch2 activation in the tumour microenvironment is a pre-requisite for the GSK3-â dependent activation of the canonical Wnt-signaling in tumor cells.
