Abstract

Hepcidin regulates systemic iron homeostasis. Suppression of hepcidin expression occurs physiologically in iron deficiency and increased erythropoiesis but is pathologic in thalassemia and hemochromatosis. Here we show that epigenetic events govern hepcidin expression. Erythropoiesis and iron deficiency suppress hepcidin via erythroferrone-dependent and -independent mechanisms, respectively, in vivo, but both involve reversible loss of H3K9ac and H3K4me3 at the hepcidin locus. In vitro, pan-histone deacetylase inhibition elevates hepcidin expression, and in vivo maintains H3K9ac at hepcidin-associated chromatin and abrogates hepcidin suppression by erythropoietin, iron deficiency, thalassemia, and hemochromatosis. Histone deacetylase 3 and its cofactor NCOR1 regulate hepcidin; histone deacetylase 3 binds chromatin at the hepcidin locus, and histone deacetylase 3 knockdown counteracts hepcidin suppression induced either by erythroferrone or by inhibiting bone morphogenetic protein signaling. In iron deficient mice, the histone deacetylase 3 inhibitor RGFP966 increases hepcidin, and RNA sequencing confirms hepcidin is one of the genes most differentially regulated by this drug in vivo. We conclude that suppression of hepcidin expression involves epigenetic regulation by histone deacetylase 3., Hepcidin controls systemic iron levels by inhibiting intestinal iron absorption and iron recycling. Here, Pasricha et al. demonstrate that the hepcidin-chromatin locus displays HDAC3-mediated reversible epigenetic modifications during both erythropoiesis and iron deficiency.

EHA Roadmap for European Hematology Research

Abstract

The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at ∈ European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better fu treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine ‘sections’ in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients. © 2016 Ferrata Storti Foundation.

Abstract

The poly(A) tail plays an important role in translation initiation. We report the identification of a mechanism that operates in mammalian somatic cells, and couples mRNA poly(A) tail length with its translation state. The regulation of human ferritin L-chain mRNA by iron-responsive elements (IREs) and iron regulatory proteins (IRPs) is subject to this mechanism: translational repression imposed by IRP binding to the IRE of ferritin L-chain mRNA induces poly(A) tail shortening. For the accumulation of mRNAs with short poly(A) tails, IRP binding to an IRE per se is not sufficient, but must cause translational repression. Interestingly, puromycin and verrucarin (general translation inhibitors that dissociate mRNAs from ribosomes) mimick the negative effect of the specific translational repressor proteins on poly(A) tail length, whereas cycloheximide and anisomycin (general translation inhibitors that maintain the association between mRNAs and ribosomes) preserve long poly(A) tails. Thus, the ribosome association of the mRNA appears to represent the critical determinant. These findings identify a novel mechanism of regulated polyadenylation as a consequence of translational control. They reveal differences in poly(A) tail metabolism between polysomal and mRNP-associated mRNAs. A possible role of this mechanism in the maintenance of translational repression is discussed.

Abstract

WOS: 000379156300012, PubMed ID: 26819058, The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at (sic)23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients., Biotechnology and Biological Sciences Research CouncilBiotechnology and Biological Sciences Research Council (BBSRC) [BB/L023776/1, BB/I00050X/1, BB/K021168/1]; Cancer Research UKCancer Research UK [11831]; Medical Research CouncilMedical Research Council UK (MRC) [G1000801a]; Novo Nordisk FondenNovo Nordisk [NNF12OC1015986]; British Heart FoundationBritish Heart Foundation [FS/09/039/27788]; Cancer Research UKCancer Research UK [12765]; Medical Research CouncilMedical Research Council UK (MRC) [MR/L022982/1, MC_UU_12009/8, MC_U137981013, MC_PC_12009]

Abstract

Background Iron deficiency affects up to 50% of patients with pulmonary arterial hypertension (PAH) but iron markers such as ferritin and serum iron are confounded by several non-disease related factors like acute inflammation and diet. The aim of this study was to identify a new marker for iron deficiency and clinical outcome in PAH patients. Methods In this single-center, retrospective study we assessed indicators of iron status and clinical parameters specifying the time to clinical worsening (TTCW) and survival in PAH patients at time of initial diagnosis and at 1-year follow-up using univariable and multivariable analysis. Results In total, 150 patients were included with an invasively confirmed PAH and complete data on iron metabolism. The proportion of hypochromic erythrocytes > 2% at initial diagnosis was identified as an independent predictor for a shorter TTCW (p = 0.0001) and worse survival (p = 0.002) at initial diagnosis as well as worse survival (p = 0.016) at 1-year follow-up. Only a subset of these patients (64%) suffered from iron deficiency. Low ferritin or low serum iron neither correlated with TTCW nor survival. Severe hemoglobin deficiency at baseline was significantly associated with a shorter TTCW (p = 0.001). Conclusions The presence of hypochromic erythrocytes > 2% was a strong and independent predictor of mortality and shorter TTCW in this cohort of PAH patients. Thus, it can serve as a valuable indicator of iron homeostasis and prognosis even in patients without iron deficiency or anemia. Further studies are needed to confirm the results and to investigate therapeutic implications.

ERG-related patients have remarkably favorable outcome despite a high incidence of inauspicious IKZF1 aberrations. We describe clinical and genomic features of the ERG-related cases in an unselected cohort of B-other BCP ALL pediatric patients enrolled in the AIEOP ALL 2000 therapeutic protocol. We report a small noncoding RNA signature specific of ERG-related group, with up-regulation of miR-125b-2 cluster on chromosome 21 and several snoRNAs in the Prader-Willi locus at 15q11.2, including the orphan SNORD116 cluster.

Abstract

Purpose Somatic deletions that affect the lymphoid transcription factor–coding gene IKZF1 have previously been reported as independently associated with a poor prognosis in pediatric B-cell precursor (BCP) acute lymphoblastic leukemia (ALL). We have now refined the prognostic strength of IKZF1 deletions by analyzing the effect of co-occurring deletions. Patients and Methods The analysis involved 991 patients with BCP ALL treated in the Associazione Italiana Ematologia ed Oncologia Pediatrica–Berlin-Frankfurt-Muenster (AIEOP-BFM) ALL 2000 trial with complete information for copy number alterations of IKZF1, PAX5, ETV6, RB1, BTG1, EBF1, CDKN2A, CDKN2B, Xp22.33/Yp11.31 (PAR1 region; CRLF2, CSF2RA, and IL3RA), and ERG; replication of findings involved 417 patients from the same trial. Results IKZF1 deletions that co-occurred with deletions in CDKN2A, CDKN2B, PAX5, or PAR1 in the absence of ERG deletion conferred the worst outcome and, consequently, were grouped as IKZF1plus. The IKZF1plus group comprised 6% of patients with BCP ALL, with a 5-year event-free survival of 53 ± 6% compared with 79 ± 5% in patients with IKZF1 deletion who did not fulfill the IKZF1plus definition and 87 ± 1% in patients who lacked an IKZF1 deletion ( P ≤ .001). Respective 5-year cumulative relapse incidence rates were 44 ± 6%, 11 ± 4%, and 10 ± 1% ( P ≤ .001). Results were confirmed in the replication cohort, and multivariable analyses demonstrated independence of IKZF1plus. The IKZF1plus prognostic effect differed dramatically in analyses stratified by minimal residual disease (MRD) levels after induction treatment: 5-year event-free survival for MRD standard-risk IKZF1plus patients was 94 ± 5% versus 40 ± 10% in MRD intermediate- and 30 ± 14% in high-risk IKZF1plus patients ( P ≤ .001). Corresponding 5-year cumulative incidence of relapse rates were 6 ± 6%, 60 ± 10%, and 60 ± 17% ( P ≤ .001). Conclusion IKZF1plus describes a new MRD-dependent very-poor prognostic profile in BCP ALL. Because current AIEOP-BFM treatment is largely ineffective for MRD-positive IKZF1plus patients, new experimental treatment approaches will be evaluated in our upcoming trial AIEOP-BFM ALL 2017.

Abstract

Gain-of-function somatic mutations introducing cysteines to either the extracellular or to the transmembrane domain (TMD) in interleukin-7 receptor α (IL7R) or cytokine receptor-like factor 2 (CRLF2) have been described in acute lymphoblastic leukemias. Here we report noncysteine in-frame mutations in IL7R and CRLF2 located in a region of the TMD closer to the cytosolic domain. Biochemical and functional assays showed that these are activating mutations conferring cytokine-independent growth of progenitor lymphoid cells in vitro and are transforming in vivo. Protein fragment complementation assays suggest that despite the absence of cysteines, the mechanism of activation is through ligand-independent dimerization. Mutagenesis experiments and ConSurf calculations suggest that the mutations stabilize the homodimeric conformation, positioning the cytosolic kinases in predefined orientation to each other, thereby inducing spontaneous receptor activation independently of external signals. Hence, type I cytokine receptors may be activated in leukemia through 2 types of transmembrane somatic dimerizing mutations.

Abstract

OBJECTIVES: microRNAs (miRNAs) are short RNAs that regulate gene expression in various processes, including immune response. Altered immune response is a pivotal event in the pathogenesis of celiac disease (CD), and miRNAs could have a role in modulating both innate and adaptive response to gluten in celiac patients. METHODS: We compared miRNA profiles in duodenal biopsies of controls and CD patients by miRNA array. Differentially expressed miRNAs were validated in controls, Marsh 3A-B, and Marsh 3C patients by quantitative PCR (qPCR). Target gene expression was assessed by qPCR, western blotting, and immunohistochemistry, and the effect of gliadin was evaluated by in vitro stimulation experiments on duodenal biopsies. RESULTS: Seven miRNAs were identified as significantly downregulated in the duodenum of adult CD patients as compared with controls. qPCR validated the decreased expression of miR-192-5p, miR-31-5p, miR-338-3p, and miR-197, in particular in patients with more severe histological lesions (Marsh 3C). In silico analysis of possible miRNA targets identified several genes involved in innate and adaptive immunity. Among these, chemokine C-X-C motif ligand 2 (CXCL2) and NOD2 showed significantly increased mRNA and protein level in Marsh 3C patients and a significant inverse correlation with the regulatory miR-192-5p. In addition, forkhead box P3 (FOXP3), Run-related transcription factor 1, and interleukin-18 (targets of miR-31-5p, miR-338-3p, and miR-197, respectively) showed upregulation in CD patients. Furthermore, alterations in CXCL2 and NOD2, FOXP3, miR-192-5p, and miR-31-5p expression were triggered by gliadin exposure in CD patients. CONCLUSIONS: miRNA expression is significantly altered in duodenal mucosa of CD patients, and this alteration can increase the expression of molecules involved in immune response.

Abstract

IL7R-activating mutations identified in B-ALL and T-ALL patient leukemic cells facilitate cytokine-independent growth., Interleukin-7 receptor α (IL7R) is required for normal lymphoid development. Loss-of-function mutations in this gene cause autosomal recessive severe combined immune deficiency. Here, we describe somatic gain-of-function mutations in IL7R in pediatric B and T acute lymphoblastic leukemias. The mutations cause either a serine-to-cysteine substitution at amino acid 185 in the extracellular domain (4 patients) or in-frame insertions and deletions in the transmembrane domain (35 patients). In B cell precursor leukemias, the mutations were associated with the aberrant expression of cytokine receptor-like factor 2 (CRLF2), and the mutant IL-7R proteins formed a functional receptor with CRLF2 for thymic stromal lymphopoietin (TSLP). Biochemical and functional assays reveal that these IL7R mutations are activating mutations conferring cytokine-independent growth of progenitor lymphoid cells. A cysteine, included in all but three of the mutated IL-7R alleles, is essential for the constitutive activation of the receptor. This is the first demonstration of gain-of-function mutations of IL7R. Our current and recent observations of mutations in IL7R and CRLF2, respectively suggest that the addition of cysteine to the juxtamembranous domains is a general mechanism for mutational activation of type I cytokine receptors in leukemia.

Abstract

Background & Aims: Haptoglobin is an acute phase protein responsible for the recovery of free hemoglobin from plasma. Haptoglobin-mill mice were previously shown to have an altered heme-iron distribution, thus reproducing what occurs in humans in cases of congenital or acquired anhaptoglobinemia. Here, we report the analysis of iron homeostasis in haptoglobin-mill mice. Methods: Iron absorption was measured in tied-off duodenal segments. Iron stores were evaluated on tissue homogenates and sections. The expression of molecules involved in iron homeostasis was analyzed at the protein and messenger RNA levels both in mice and in murine RAW264.7 macrophages stimulated in vitro with hemoglobin. Results: Analysis of intestinal iron transport reveals that haptoglobin-null mice export significantly more iron from the duodenal mucosa to plasma compared with control counterparts. Increased iron export from the duodenum correlates with increased duodenal expression of ferroportin, both at the protein and messenger RNA levels, whereas hepatic hepcidin expression remains unchanged. Up-regulation of the ferroportin transcript, but not of the protein, also occurs in haptoglobin-null spleen macrophages, which accumulate free hemoglobin-derived iron. Finally, we demonstrate that hemoglobin induces ferroportin expression in RAW264.7 cells. Conclusions: Taking together these data, we suggest that haptoglobin, by controlling plasma levels of hemoglobin, participates in the regulation of ferroportin expression, thus contributing to the regulation of iron transfer from duodenal mucosa to plasma.

Alteration of CRLF2 gene, a hallmark correlated with poor outcome in BCP-ALL, has not been reported in T-ALL. We analyzed CRLF2 expression in 212 T-ALL pediatric patients enrolled in AIEOP-BFM ALL2000 study in Italian and German centers. Seventeen out of 120 (14.2%) Italian patients presented CRLF2 mRNA expression 5 times higher than the median ( CRLF2-high ); they had a significantly inferior event-free survival (41.2%±11.9 vs. 68.9%±4.6, p=0.006) and overall survival (47.1%±12.1 vs. 73.8%±4.3, p=0.009) and an increased cumulative incidence of relapse/resistance (52.9%±12.1 vs. 26.2%±4.3, p=0.007) compared to CRLF2-low patients. The prognostic value of CRLF2 over-expression was validated in the German cohort. Of note, CRLF2 over-expression was associated with poor prognosis in the high risk (HR) subgroup where CRLF2-high patients were more frequently allocated. Interestingly, although in T-ALL CRLF2 protein was localized mainly in the cytoplasm, in CRLF2-high blasts we found a trend towards a stronger TSLP-induced pSTAT5 response, sensitive to the JAK inhibitor Ruxolitinib. In conclusion, CRLF2 over-expression is a poor prognostic marker identifying a subset of HR T-ALL patients that could benefit from alternative therapy, potentially targeting the CRLF2 pathway.
