(Submitter supplied) We generated mice with a mutation at threonine 58 of MYC in the mouse germline (T58A mutant). These mice ultimately develop AML or B cell lymphomas. We profiled changes in gene expression and genomic occupation of MYC in single cells of sorted, immature bone marrow progenitor cells, mature (spleen derived) and immature (marrow derived) B cells. B cells were stimulated with LPS and IL7, respectively.

(Submitter supplied) Ubiquitination is a post-translational mechanism of control of diverse cellular processes. We focus here on the ubiquitin ligase Fbw7, a recently identified hematopoietic tumor suppressor that can target for degradation several important oncogenes including Notch1, c-Myc and cyclin E. We have generated conditional Fbw7 knock-out animals and inactivated the gene in hematopoietic stem cells (HSC) and their differentiated progeny. more...

(Submitter supplied) cMyc plays a major role in lymphoma development. In addition, missense mutations including T58A and T58I the substitution mutations augment cMyc activity during lymphoma development. In this study, we characterized lymphoma-associated gene expression changes as increasing levels of wild type or mutant cMyc proteins progressively drive conversion of B-cells to lymphoma-like cells. To this end we established a cell system in which primary mouse B-cells were transduced with constructs that over-express the anti-apoptotic proteins, BMI1 and BCLXL and allow variable expression of cMyc (wild type, T58A or T58I) from a doxycycline-regulated promoter. more...

(Submitter supplied) Fbw7 is one of the most highly mutated tumor suppressor genes in human cancers. Several Fbw7 mutation types have been found in cancers (e.g. Fbw7Arg/+, other missense mutations and Fbw7-/-). Fbw7Arg/+ missense mutation is the most commonly observed mutation type, however the tumorigenic mechanisms led by Fbw7Arg/+ are as of yet poorly understood. Fbw7 targets almost thirty proteins to degradation, out of many are transcription factors. more...

(Submitter supplied) The NOTCH signaling cascade, which is deregulated in T-cell acute lymphoblastic leukemia (T-ALL) and many other human cancers, offers an attractive target for molecular therapy. One approach employs gamma-secretase inhibitors (GSIs) to suppress production of the intracellular form of NOTCH (NICD), leading to cell growth arrest and apoptosis. Here we show that missense mutations or homozygous deletion of FBW7, which encodes a ubiquitin ligase that targets the NICD for destruction, mediate constitutive NICD expression. more...

(Submitter supplied) Fbw7 is a tumor suppressor protein that regulates the degradation of a multitude of oncogenic substrates, such as c-Jun, c-Myc, Notch1 intracellular domain, and cyclin E. Loss of FBXW7 expression is relatively common in breast cancer. Despite this, the effect of FBXW7 loss on breast tumorigenesis has not been examined. We demonstrate here that loss of FBXW7 is sufficient for breast tumorigenesis. Many of Fbw7’s substrates are transcription factors or are closely linked to transcription factor pathways. more...

(Submitter supplied) To test how translational control of proteome quality affects stem cell function, we examined Aarssti/sti mice that harbor a mutation in the alanyl-tRNA synthetase, which causes a tRNA editing defect that increases amino acid misincorporation errors during translation. Aarssti/sti mice exhibited reduced HSC numbers, increased HSC proliferation and significantly diminished HSC serial reconstituting activity in vivo, but did not exhibit defects within restricted progenitors. more...

(Submitter supplied) The proto-oncogene MYCN is mis-expressed in various types of human brain tumors. To clarify how developmental and regional differences influence transformation, we transduced wild-type or mutationally-stabilized murine N-mycT58A into neural stem cells (NSCs) from perinatal murine cerebellum, brain stem and forebrain. Transplantation of Nmyc WT NSCs was insufficient for tumor formation. N-mycT58A cerebellar and brain stem NSCs generated medulloblastoma/primitive neuroectodermal tumors, whereas forebrain NSCs developed diffuse glioma. more...

(Submitter supplied) By using a genetically accurate mouse model, we demonstrate that endogenous expression of oncogenic N-RasG12D and Tet2 haploinsufficiency collaborate to accelerate CMML development in mice. Gene expression was compared across all genotypes (WT, Tet2+/-, NrasG12D/+ and double mutants) in bone marrow-derived hematopoietic stem cells (CD150+CD48-Lin-Sca1+cKit+) using RNA-seq. N-RasG12D and Tet2 haploinsufficiency cooperate to induce both unique and overlapping effects on HSC gene expression programs.

(Submitter supplied) Oncogenic NRAS mutations are frequently identified in human myeloid leukemias. In mice, expression of endogenous oncogenic Nras (NrasG12D/+) in hematopoietic cells leads to expansion of myeloid progenitors, increased long-term reconstitution of bone marrow cells, and a chronic myeloproliferative neoplasm (MPN). However, acute expression of NrasG12D/+ in a pure C57BL/6 background does not induce hyperactivated GM-CSF signaling or increased proliferation in myeloid progenitors. more...
