(Submitter supplied) Notch signaling defines a conserved, fundamental pathway, responsible for determination in metazoan development and is widely recognized as an essential component of lineage specific differentiation and stem cell self-renewal in many tissues including the hematopoietic system. Until recently, the majority of studies in the hematopoietic system focused on Notch signaling in lymphocyte differentiation and knowledge of individual Notch receptor roles in early hematopoiesis has been limited due to a paucity of genetic tools available To fate-map Notch receptor expression and pathway activity in the hematopoietic system we used tamoxifen-inducible CreER knock-in mice for individual Notch receptors in combination to a novel Notch reporter strain (Hes1GFP) and a conditional gain of function allele of Notch2 receptor (Rosa-lsl-ICN2).

(Submitter supplied) Notch signaling regulates several cellular processes including cell fate decisions and proliferation in both invertebrates and mice. However, comparatively less is known about the role of Notch during early human development. Here, we examined the function of Notch signaling during hematopoietic lineage specification from human pluripotent stem cells (hPSCs) of both embryonic and adult fibroblast origin. more...

(Submitter supplied) Bladder cancer (BC) is a highly prevalent human disease in which Rb pathway inactivation and epigenetic alterations are common events. However, the connection between these two processes is still poorly understood. Here we show that the in vivo inactivation of all Rb family genes in the mouse urothelium is sufficient to initiate BC development. The characterization of the mouse tumors revealed multiple molecular features of human BC, including the activation of E2F transcription factor and subsequent Ezh2 expression, and the activation of several signaling pathways previously identified as highly relevant in urothelial tumors. more...

(Submitter supplied) In both mouse and human, Notch1 activation is the main initial driver to induce T-cell development in hematopoietic progenitor cells. The initiation of this developmental process coincides with Notch1-dependent repression of differentiation towards other hematopoietic lineages. Although well described in mice, the role of the individual Notch1 target genes during these hematopoietic developmental choices is still unclear in human. more...

(Submitter supplied) There is evidence that brain tumor cells may hijack self-renewal mechanism that regulate stem cell maintenance during normal development. Notch signaling is fundamental for maintaining normal neural stem cells in an undifferentiated state and has been implicated in in the maintenance of brain tumor stem cells as well. We used microarrays to detail the global gene expression program in murine brain tumors lacking RBPjk, an indispensable mediator of the Notch signaling pathway in the cell nucleus.

(Submitter supplied) MEIS1 is a transcription factor expressed in hematopoietic stem and progenitor cells (HSPC) and in mature megakaryocytes. In contrast to its role in leukemogenesis, the role of MEIS1 in normal hematopoiesis is largely unknown. We show that MEIS1 can direct human hematopoietic progenitors towards a megakaryocyte-erythroid progenitor (MEP) fate. Ectopoic expression of MEIS1 in CD34+ cells resulted in increased erythroid differentiation at the expense of granulocyte and monocyte (GM) differentiation. more...

(Submitter supplied) Notch signaling regulates a variety of developmental cell fates decisions in a cell-context dependent manner. Although Notch signaling directly regulates transcription via the RBP-J/CSL DNA binding protein, little is known about the genes in the respective tissues that are directly activated by Notch. To analyze how Notch signaling mediates its context dependent functions, we utilized a Tamoxifen(OHT)-inducible system (NERT) to activate Notch1 in embryonic stem cells (ESC) at different stages of mesodermal differentiation combined with global transcriptional analyses.
