ABSTRACT: Notch signaling is one of the central regulators of differentiation in a variety of organisms and tissue types. Within the hematopoietic system, Notch is essential for the emergence of definitive HSC during fetal life and controls adult HSC differentiation to the T-cell lineage. Notch activation is controlled by the gamma-secretase complex complex, composed of presenilin, nicastrin (Ncstn), anterior pharynx-1 (Aph1), and presenilin enhancer-2 To determine other role of Notch signaling in HSC we designed a conditional mouse model of Notch activation. WT and N1-IC+ HSC were analysed to determined genes controlled by Notch signaling. Bone marrow lineage negative, cKit+, Sca1+ cells were sorted from WT and N1-IC+ littermates for RNA extraction and hybridization on Affymetrix microarrays

Notch signalling is a central regulator of differentiation in a variety of organisms and tissue types. Its activity is controlled by the multi-subunit γ-secretase (γSE) complex. Although Notch signalling can play both oncogenic and tumour-suppressor roles in solid tumours, in the haematopoietic system it is exclusively oncogenic, notably in T-cell acute lymphoblastic leukaemia, a disease characterized by Notch1-activating mutations. Here we identify novel somatic-inactivating Notch pathway mutat  ...[more]
