(Submitter supplied) Recent studies using next-generation sequencing technology have uncovered mutational landscapes of various myeloid malignancies (Cancer Genome Atlas Research Network, 2013; Yoshida et al., 2011). These genetic data revealed novel classes of mutations that commonly occur in patients with myeloid malignancies, including epigenetic regulators and spliceosomal genes. In addition, co-occurrence and mutual exclusivity of these disease alleles suggest convergent cooperative roles or common biological effects of specific alleles in myeloid leukemogenesis (Shih et al., 2012). 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) Epigenetic gene regulation and metabolism are highly intertwined, yet little is known whether and how altered epigenetics influences cellular metabolism in cancer progression. Here we show that EZH2 and NRasG12D mutations cooperatively induce progression of myeloproliferative neoplasms to fully penetrant, transplantable and lethal myeloid leukemias in mouse. EZH1, an EZH2 homolog, is indispensable for EZH2-deficient leukemia-initiating cells (LICs) and constitutes an epigenetic vulnerability. more...

(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...

(Submitter supplied) Contemporary treatment of pediatric acute myeloid leukemia (AML) requires the assignment of patients to specific risk groups. To explore whether expression profiling of leukemic blasts could accurately distinguish between the known risk groups of AML, we analyzed 130 pediatric and 20 adult AML diagnostic bone marrow or peripheral blood samples using the Affymetrix U133A microarray. Class discriminating genes were identified for each of the major prognostic subtypes of pediatric AML, including t(15;17)[PML-RARalpha], t(8;21)[AML1-ETO], inv(16) [CBFbeta-MYH11], MLL chimeric fusion genes, and cases classified as FAB-M7. more...

(Submitter supplied) Acute lymphoblastic leukaemia with early T-cell precursor immunophenotype (ETP ALL) is a highly aggressive subtype of ALL of unknown aetiology. To gain insights into the genetic basis of this disease, we performed whole genome sequencing of tumour and normal DNA of 12 children with ETP ALL. Analysis of structural and sequence variants in this discovery cohort, and mutation recurrence screening in a panel of 51 ETP and 43 non ETP ALL samples identified a high frequency of activating mutations in genes regulating cytokine receptor and Ras signalling, including IL7R, NRAS, KRAS, FLT3, BRAF, JAK1 and JAK3 in ETP ALL. more...

(Submitter supplied) Chronic myelomonocytic leukemia (CMML) has recently been associated with a high incidence of diverse mutations in genes implicated in epigenetic mechanisms such as TET2 or EZH2. We have performed genome-wide methylation arrays and mutational analysis of TET2, IDH1, IDH2, EZH2 and JAK2 in a group of 24 patients with CMML. 249 genes were differentially methylated between CMML patients and controls. Using Ingenuity pathway analysis enrichment in a gene network centered in PLC, JNK and ERK, a recently described pathway involved in CMML was found, suggesting the potential role of epigenetics in the regulation of these pathways. more...

(Submitter supplied) Mutations in SET binding protein 1 (SETBP1) are associated with poor outcomes in myeloid leukemias. In the Ras-driven leukemia, juvenile myelomonocytic leukemia, SETBP1 mutations are enriched in relapsed disease. We demonstrate that SETBP1 enhances the NRAS gene expression signature, driving upregulation of mitogen-activated protein kinase (MAPK) signaling and downregulation of differentiation pathways.

(Submitter supplied) Recent studies have shown that both TET2 mutation and JAK2V617F mutation are frequent in myeloproliferative neoplasms patients. The pathophysiological roles of each mutation have been elucidated in murine models, but the cooperative effect of the two mutations has not been elucidated yet. In this study, we examined the function of the cooperative effect of loss-of-TET2 function and JAK2V617F mutation in murine hematopoiesis.

(Submitter supplied) Recurrent somatic mutations in TET2 and in other genes that regulate the epigenetic state have been identified in patients with myeloid malignancies and in other cancers. However, the in vivo effects of Tet2 loss have not been delineated. We report here that Tet2 loss leads to increased stem-cell self-renewal and to progressive stem cell expansion. Consistent with human mutational data, Tet2 loss leads to myeloproliferation in vivo, notable for splenomegaly and monocytic proliferation. more...

Comparisons were made across genotypes WT vs. T2F3 and cell types LSK vs. GMP.

(Submitter supplied) Studies of AML patient samples have shown that specific combinations of AML disease alleles confer an adverse outcome, however, in vivo models do not exist for the majority of common, poor-prognosis genotypes. Here we show that TET2/FLT3 mutations can cooperate to induce AML in vivo using a genetically engineered mouse model, and that this model has a defined stem-cell population with a characteristic transcriptional and epigenetic profile. more...
