Gene expression signature associated with ASXL1 mutations in cytogenetically normal acute myeloid leukemia (CN-AML)

ABSTRACT: We studied gene expression profiles from 65 patients with CN-AML, who all had wild-type NPM1 and no FLT3-ITD. We identified an ASXL1 mutation-associated gene expression signature by comparing 26 ASXL1-mutated and 39 ASXL1-wild type patients. Only NPM1 wild type/FLT3-ITD-negative patients were included in this analysis to avoid potential confounding due to the effects of these two mutations on gene expression.

The associations of mutations in the enhancer of trithorax and polycomb family gene ASXL1 with pretreatment patient characteristics, outcomes, and gene-/microRNA-expression profiles in primary cytogenetically normal acute myeloid leukemia (CN-AML) are unknown. We analyzed 423 adult patients for ASXL1 mutations, other prognostic gene mutations, and gene-/microRNA-expression profiles. ASXL1 mutations were 5 times more common in older (≥ 60 years) patients (16.2%) than those younger than 60 years ( ...[more]

Gene Expression Signature Predicts Relapse in Adult Patients with Cytogenetically Normal Acute Myeloid Leukemia

Project description:Although approximately 80% of adult patients with cytogenetically normal acute myeloid leukemia (CN-AML) achieve a complete remission (CR), over half of them relapse. Better identification of patients who are likely to relapse can help inform clinical decisions. We performed RNA sequencing on pretreatment samples from 268 adults with de novo CN-AML younger than 60 years who achieved a CR after induction treatment with standard “7+3” chemotherapy. After filtering for genes whose expressions were associated with gene mutations known to impact on outcome (i.e., CEBPA, NPM1, and FLT3-internal tandem duplication [FLT3-ITD]), we identified a 10-gene signature strongly predictive of patient relapse (area under the curve [AUC]=0.81). The signature consisted of seven coding genes: GAS6, PSD3, PLCB4, DEXI, JMY, NRP1, C10orf55, and three long non-coding RNAs. In multivariable analysis, the 10-gene signature was strongly associated with relapse (P<.001), after adjustment for the FLT3-ITD, CEBPA and NPM1 mutational status. Validation of the expression signature in an independent patient set from The Cancer Genome Atlas showed the signature’s strong predictive value with AUC=0.78. Implementation of the 10-gene signature into clinical prognostic stratification could be useful for identifying patients likely to relapse.

Multilineage dysplasia and AML with mutated nucleophosmin

Project description:Multilineage dysplasia (MLD) has no impact on biological, clinico-pathological and prognostic features of AML with mutated nucleophosmin (NPM1) NPM1-mutated AML is a provisional entity in the WHO-2008 classification of myeloid neoplasms. The significance of concomitant multilineage dysplasia (MLD) in NPM1-mutated AML is unclear. Thus, in the WHO-2008 classification, NPM1-mutated AML with MLD is classified as AML with myelodysplasia(MD)-related changes. We evaluated the MLD impact in 378 NPM1-mutated AML patients. MLD was found in about 25% cases. Except for a lower WBC and FLT3-ITD incidence in MLD+ group, no significant differences were observed in age, sex, cytogenetics and FLT3-TKD between NPM1-mutated AML with and without MLD. Notably, NPM1-mutated AML with/without MLD showed overlapping immunophenotype (CD34-negativity) and GEP (CD34 downregulation and HOX genes upregulation). Moreover, OS and EFS did not differ among NPM1-mutated AML patients, independently of whether they carried or not MLD, the NPM1-mutated/FLT3-ITD negative cases showing the better prognosis. Lack of MLD impact on survival was confirmed by multivariate analysis that highlighted FLT3-ITD as the most significant prognostic parameter in NPM1-mutated AML. Our findings indicate that NPM1 mutations rather than MLD dictate the distinctive features of NPM1-mutated AML. Thus, irrespective of MLD, NPM1-mutated AML should be considered as one disease entity clearly distinct from AML with MD-related changes. These findings have important diagnostic and prognostic implications in AML. All bone marrow samples were obtained from untreated patients at the time of diagnosis. Cells used for microarray analysis were collected from the purified fraction of mononuclear cells after Ficoll density centrifugation. 48 samples

Crenolanib in combination with azacitidine abrogates stromal protection and survival of leukemia-initiating cells in FLT3-ITD+ AML

Project description:Effectively targeting leukemia-initiating cells (LIC) in FLT3-internal-tandem-duplication (ITD)-mutated acute myeloid leukemia (AML) remains a crucial goal for achievement of cure. FLT3 tyrosine kinase inhibitors (TKI) have limited impact as single agents and have thus far been unable to eradicate LIC enriched in the CD34+CD38- bone marrow compartment and protected by contact with niche cells.Using primary AML samples in vitro as well as in an in vivo xenograft model, we investigated whether combining the novel FLT3-selective TKI crenolanib with the hypomethylating agent azacitidine (AZA) can eliminate LIC in FLT3-ITD+ AML and determined whether efficacy of this combination is dependent on coexisting genetic mutations in DNMT3A, NPM1 and TET2. Our data show that crenolanib as a single agent was unable to target FLT3-ITD+ LIC in contact with niche cells while the addition of AZA overcame stromal protection and resulted in dramatically reduced clonogenic capacity of FLT3-ITD+ LIC in vitro as well as severely impaired engraftment capacity of FLT3-ITD+ LIC in NSG mice. Strikingly, FLT3-mutated AML samples harboring concurrent TET2 mutations were completely resistant to crenolanib as a single agent. Mutations in DNMT3A or NPM1 had no influence on response to crenolanib while DNMT3A mutations conferred increased sensitivity of FLT3-ITD+ LIC to AZA. Our data suggest that response to crenolanib or AZA as single agents in FLT3-ITD+ AML is highly dependent on coexisting mutations in epigenetic regulators. However, the combination of AZA + crenolanib effectively eliminated FLT3-ITD+ LIC irrespective of additional mutations in NPM1, DNMT3A or TET2.

Loss of Asxl1 Alters Self-Renewal and Cell Fate of Bone Marrow Stromal Cell

Project description:De novo ASXL1 mutations are found in patients with Bohring-Opitz syndrome, a disease with severe developmental defects and early childhood fatality. The underlying pathologic mechanisms remain largely unknown. Using Asxl1-targeted murine models,we found that Asxl1 global loss or conditional deletion in osteoblasts and their progenitors in mice leads to significant bone loss and markedly decreased numbers of marrow mesenchymal stem/progenitor cells (MSPCs) compared with wild-type (WT) littermates. Asxl1-/- MSPCs displayed impaired self-renewal and skewed differentiation-away from osteoblasts and favoring adipocytes. RNA-seq analysis reveals the altered expression of genes involved in cell proliferation, skeletal development and morphogenesis. Furthermore, gene set enrichment analysis showed a decreased gene expression of stem cell self-renewal signature,suggesting the role of Asxl1 in regulating the stemness of MSPCs. Importantly, introducing Asxl1 normalized NANOG and OCT4 expression and restored the self-renewal capacity of Asxl1-/- MSPCs. Our study unveils a pivotal role of ASXL1 in maintenance of MSPC functions and skeletal development. Examination of mRNA profiles in wild type and Asxl1-/- MSPCs by deep sequencing

SYK Is a Critical Regulator of FLT3 In Acute Myeloid Leukemia

Project description:Cooperative dependencies between mutant oncoproteins and wild-type proteins are critical in cancer pathogenesis and therapy resistance. Although spleen tyrosine kinase (SYK) has been implicated in hematologic malignancies, it is rarely mutated. We used kinase activity profiling to identify collaborators of SYK in acute myeloid leukemia (AML) and determined that FMS-like tyrosine kinase 3 (FLT3) is transactivated by SYK via direct binding. Highly activated SYK is predominantly found in FLT3-ITD positive AML and cooperates with FLT3-ITD to activate MYC transcriptional programs. FLT3-ITD AML cells are more vulnerable to SYK suppression than FLT3 wild-type counterparts. In a FLT3-ITD in vivo model, SYK is indispensable for myeloproliferative disease (MPD) development, and SYK overexpression promotes overt transformation to AML and resistance to FLT3-ITD-targeted therapy.

Molecular variability of FLT3/ITD mutants and their impact on the differentiation program of 32D cells

Project description:FLT3 is the most frequently mutated gene in AML â up to 40% of AML harbor an activating mutation within FLT3 gene. Though AML is a relatively rare disease, such a high mutability rate, as observed with FLT3 gene, is striking. To elucidate the molecular background of this phenomenon, we have established nine unique FLT3/ITD - carrying 32D cell lines and a set of controls, and subjected them to whole genome expression analysis and 2DE LC/MS proteomics. Data obtained on this so far largest set of ITD mutants indicates that in comparison to the wild type FLT3 expressing 32D cells and transduction controls, FLT3/ITD positive cells exhibit less mature expression profiles resembling ST-HSC and MkEP/CMP/LMPP progenitors. We hypothesize that FLT3/ITD might contribute not only to the proliferative advantage of FLT3/ITD positive cells, but also to their reprogramming towards less differentiated stages, thus strengthening their malignant properties. This finding might explain the pronounced mutation rate of the aberrantly expressed FLT3 gene in AML, and, also, the inferior prognosis of FLT3/ITD positive AML patients. Moreover, the microarray data has revealed biological differences among individual ITD variants â a finding supporting the recent clinical data on the prognostic impact of the size of individual ITDs. Keywords: genetic modification Nine stable 32D cell lines harboring unique human FLT3/ITD mutants, two parental 32 cell lines, two 32D stable cell lines harboring cloning vector only, and two 32D cell lines stably expressing human wild type FLT3 were subjected to the microarray analysis.
