(Submitter supplied) We used expression profiling, SNP arrays, and mutational profiling to investigate a well-characterized cohort of MPN patients. MPN patients with homozygous JAK2V617F mutations were characterized by a distinctive transcriptional profile. Notably, a transcriptional signature consistent with activated JAK2 signaling is seen in all MPN patients regardless of clinical phenotype or mutational status. In addition, the activated JAK2 signature was present in patients with somatic CALR mutations. more...

(Submitter supplied) Somatic mutations in calreticulin (CALR) are present in approximately 40% of patients with myeloproliferative neoplasms (MPN). However, the mechanism by which mutant CALR is oncogenic is unknown. Here, we demonstrate that a megakaryocytic-specific MPN phenotype is induced when mutant CALR is over-expressed in mice and that the thrombopoietin receptor, MPL is required for mutant CALR driven transformation. more...

(Submitter supplied) Transcriptional profiling of Murine BaF3 cells infected with MPLW515L grown under either normal conditions (Naive) or in 0.8 uM INCB18424 for 4-6 weeks (Persistent). Naive and Persistent cells were then treated with either DMSO (Control) or 0.8 uM INCB18424 for 4 hours. Goal was to determine transcriptional changes conditioned upon sensitivity/resistance of BaF3 MPLW515L mutants to JAK1/2 specific inhibitor.

(Submitter supplied) Mutations in the endoplasmic reticulum (ER) chaperone calreticulin (CALR) are common in myeloproliferative neoplasm (MPN) patients, activate the thrombopoietin receptor (MPL), and mediate constitutive JAK/STAT signaling. The mechanisms by which CALR mutations cause myeloid transformation are incompletely defined. We employed mass spectrometry proteomics to identify novel CALR-mutant interacting proteins. more...

(Submitter supplied) There is growing evidence that Ph-negative myeloproliferative neoplasms (MPNs) are blood cancers in which multiple molecular mechanisms are significantly disturbed. Since their discovery in 2016, CALR (calreticulin) type 1 and type 2 driver mutations have been demonstrated to trigger pathogenic mechanisms apart from the well-documented activation of JAK2/MPL-related pathways affecting these diseases. more...

(Submitter supplied) Cancer is driven by somatic mutations that provide a fitness advantage. While targeted therapies often focus on the mutated gene or its direct downstream effectors, imbalances brought on by cell-state alterations may also confer unique vulnerabilities. In myeloproliferative neoplasms (MPN), somatic mutations in the calreticulin (CALR) gene are disease-initiating through aberrant binding of mutant CALR to the thrombopoietin receptor MPL and ligand-independent activation of JAK-STAT signaling. more...

(Submitter supplied) TAMARIN study is a Phase II, multicenter, single arm A’herns design clinical trial assessing tamoxifen’s safety and activity in reducing molecular markers of disease burden in MPN.The primary outcome (≥50% allele burden reduction at 24 weeks) was met by 3/37 patients; 5/37 additional patients showed ≥25% reductions. CD34+ HSPCs were collected from responders and non-respondersin the baseline line and 24W after tamoxifen treatment. more...

(Submitter supplied) Chronic myeloproliferative neoplasms (MPNs) exhibit a propensity for transformation to secondary acute myeloid leukemia (sAML), for which the underlying mechanisms remain poorly understood, resulting in limited treatment options and dismal clinical outcomes. Here, we performed bulk transcriptome profiling accompanied by single cell RNA-sequencing on CD34+ stem/progenitor cells from serial patient samples obtained at the chronic MPN and sAML phases, identifying aberrantly increased expression of dual-specificity phosphatase 6 (DUSP6) underlying disease transformation. more...

(Submitter supplied) Pre B cell leukemia homeobox 1 (Pbx1) regulates the balance between self-renewal and differentiation of hematopoietic stem cells, and maintains proto-oncogenic transcriptional pathways implicated in several tumors. Its aberrant expression was found in a subset of myeloproliferative neoplasms (MPN) patients bearing the JAK2V617F mutation. To investigate if Pbx1 contributes to MPN, and to explore its potential as therapeutic target, we generated a new mouse strain, that we called JP, by crossing a known JAK2V617F inducible knock-in MPN model with a Pbx1 conditional-ko. more...

(Submitter supplied) Increased energy requirement and metabolic reprograming is a hallmark of cancer cells. We found that mouse models of myeloproliferative neoplasms (MPN) expressing mutant JAK2 displayed systemic metabolic changes including hypoglycemia and adipose atrophy. Modulation of nutrient availability modified MPN manifestations and survival. Hypoglycemia in MPN mice correlated with hyperactive erythropoiesis and was due to a combination of elevated glycolysis and increased oxidative phosphorylation. more...

(Submitter supplied) NUP-17d (17d) is an effective inhibitor of Plek2 protein. NUP-17d treatment inhibits erythroblast proliferation, differentiation and enucleation in a dose-dependent manner via directly binding to Plek2 protein. To reveal the detailed involving mechanism of NUP-17d treatment, we performed RNA sequencing to analyze the gene expression profiles change in erythroblasts which were treated with NUP-17d or DMSO (NC) for 48 hours in the EPO induction culture system.
