A familial disorder characterized by ANEMIA with multinuclear ERYTHROBLASTS, karyorrhexis, asynchrony of nuclear and cytoplasmic maturation, and various nuclear abnormalities of bone marrow erythrocyte precursors (ERYTHROID PRECURSOR CELLS). Type II is the most common of the 3 types; it is often referred to as HEMPAS, based on the Hereditary Erythroblast Multinuclearity with Positive Acidified Serum test.
Hemolytic anemia due to various intrinsic defects of the erythrocyte.
A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.
Immature, nucleated ERYTHROCYTES occupying the stage of ERYTHROPOIESIS that follows formation of ERYTHROID PRECURSOR CELLS and precedes formation of RETICULOCYTES. The normal series is called normoblasts. Cells called MEGALOBLASTS are a pathologic series of erythroblasts.
Anemia characterized by larger than normal erythrocytes, increased mean corpuscular volume (MCV) and increased mean corpuscular hemoglobin (MCH).
Oxygen-carrying RED BLOOD CELLS in mammalian blood that are abnormal in structure or function.
The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction.
Surgical procedure involving either partial or entire removal of the spleen.
An excessive accumulation of iron in the body due to a greater than normal absorption of iron from the gastrointestinal tract or from parenteral injection. This may arise from idiopathic hemochromatosis, excessive iron intake, chronic alcoholism, certain types of refractory anemia, or transfusional hemosiderosis. (From Churchill's Illustrated Medical Dictionary, 1989)
A major integral transmembrane protein of the ERYTHROCYTE MEMBRANE. It is the anion exchanger responsible for electroneutral transporting in CHLORIDE IONS in exchange of BICARBONATE IONS allowing CO2 uptake and transport from tissues to lungs by the red blood cells. Genetic mutations that result in a loss of the protein function have been associated with type 4 HEREDITARY SPHEROCYTOSIS.
A broad category of proteins involved in the formation, transport and dissolution of TRANSPORT VESICLES. They play a role in the intracellular transport of molecules contained within membrane vesicles. Vesicular transport proteins are distinguished from MEMBRANE TRANSPORT PROTEINS, which move molecules across membranes, by the mode in which the molecules are transported.
The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.
The semi-permeable outer structure of a red blood cell. It is known as a red cell 'ghost' after HEMOLYSIS.
A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.
A condition of inadequate circulating red blood cells (ANEMIA) or insufficient HEMOGLOBIN due to premature destruction of red blood cells (ERYTHROCYTES).
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
A group of antigens consisting principally of Jk(a) and Jk(b), determined by allelic genes. Amorphs are encountered. Antibodies of these substances are usually weak and quite labile, stimulated by erythrocytes.
Organic chemistry methodology that mimics the modular nature of various biosynthetic processes. It uses highly reliable and selective reactions designed to "click" i.e., rapidly join small modular units together in high yield, without offensive byproducts. In combination with COMBINATORIAL CHEMISTRY TECHNIQUES, it is used for the synthesis of new compounds and combinatorial libraries.

This protection is available to both published and unpublished works. (from Circular of the United States Copyright Office, 6/30/2008)

Erythroblastic synartesis: an auto-immune dyserythropoiesis. (1/81)

Erythroblastic synartesis is a rare form of acquired dyserythropoiesis, first described by Breton-Gorius et al in 1973. This syndrome is characterized by the presence of septate-like membrane junctions and "glove finger" invaginations between erythroblasts, which are very tightly linked together. This phenomenon, responsible for ineffective erythropoiesis, leads to an isolated severe anemia with reticulocytopenia. In the following report, we describe 3 new cases of erythroblastic synartesis associated with dysimmunity and monoclonal gammapathy. In all cases, the diagnosis was suggested by characteristic morphological appearance of bone marrow smears, and further confirmed by electron microscopy. Ultrastructural examination of abnormal erythroblast clusters showed that these cells were closely approximated with characteristic intercellular membrane junctions. The pathogenesis of the dyserythropoiesis was modeled in vitro using crossed erythroblast cultures and immunoelectron microscopy: when cultured in the presence of autologous serum, the erythroblasts from the patients displayed synartesis, whereas these disappeared when cultured in normal serum. Moreover, synartesis of normal erythroblasts were induced by the patient IgG fraction. Immunogold labeling showed that the monoclonal IgG were detected in, and restricted to, the synartesis. A discrete monoclonal plasmacytosis was also found in the patient bone marrow. The adhesion receptor CD36 appeared to be concentrated in the junctions, suggesting that it might be involved in the synartesis. These experiments indicated that a monoclonal serum immunoglobulin (IgG in the present cases) directed at erythroblast membrane antigen was responsible for the erythroblast abnormalities. Specific therapy of the underlying lymphoproliferation was followed by complete remission of the anemia in these cases.  (+info)

Geographic distribution of CDA-II: did a founder effect operate in Southern Italy? (2/81)

BACKGROUND AND OBJECTIVE: Congenital dyserythropoietic anemia type II (CDA-II) is an autosomal recessive condition, whose manifestations range from mild to moderate. Its exact prevalence is unknown. Based on a recently established International Registry of CDA-II (64 unrelated kindreds), a high frequency of CDA II families living in South Italy became evident. DESIGN AND METHODS: The aim of this study was to define the haplotypes of the CDA II kindreds living in Southern Italy based on markers D20S884, D20S863, RPN, D20S841 and D20S908. These markers map to 20q11.2, within the interval of the CDAN2 gene that is responsible for CDA II. Next, we looked at these markers in kindreds from other regions of Italy and from other countries, with special attention to families having ancestors in Southern Italy. RESULTS: Evaluation of the geographic distribution of the ancestry of Italian CDA-II patients clearly demonstrated the unusually high incidence of this condition in Southern Italy. Our statistical calculations and linkage disequilibrium data also clearly demonstrate a strong association of the markers of chromosome 20 with the disease locus in our sample. Almost all the regions defined by the markers here used is in disequilibrium with the disease. Combining the data from the Italian sample together with those obtained from the non-Italian ones, we can restrict the area of highest disequilibrium to that defined by markers D20S863-D20S908. INTERPRETATION AND CONCLUSIONS: Despite the presence of this linkage disequilibrium the search for a common haplotype failed. This could suggest that the mutation was very old or that it occurred more than once on different genetic backgrounds.  (+info)

Congenital dyserythropoietic anemia type III. (3/81)

BACKGROUND AND OBJECTIVES: Congenital dyserythropoietic anemia type III (CDA-III) is a group of very rare disorders characterized by similar bone marrow morphology. The clinical picture is characterized by hemolytic anemia and dramatic bone marrow changes dominated by active erythropoiesis with big multinucleated erythroblasts. The aim of this review is to describe the clinical manifestations, laboratory findings, and management CDA-III. EVIDENCE AND INFORMATION SOURCES: The present review critically examines relevant articles and abstracts published in journals covered by the Science Citation Index and Medline. The authors have performed several studies on CDA-III. STATE OF ART AND PERSPECTIVES: The clinical and laboratory manifestations of CDA-III indicate that the gene responsible for it, which has been mapped to chromosome 15q22, is expressed not only in erythroblasts during mitosis but also in B-cells, and in cells of the retina. Preliminary results indicate genetic and phenotypic similarities between a Swedish and an American family, both with an autosomally dominant inherited form of CDA-III. It is possible that the genetic lesion is identical in these families, but the different phenotypes and modes of inheritance reported among some other cases of CDA-III are probably the results of other genetic lesions. At present, the function of the gene responsible for the Swedish (V sterbotten) variant of CDA-III (CDAN3) is unknown and it is an important goal to characterize and clone this gene in order to study its function.  (+info)

Hereditary hemochromatosis in a patient with congenital dyserythropoietic anemia. (4/81)

Herein is described the case of a young woman presenting with iron overload and macrocytosis. The initial diagnosis was hereditary hemochromatosis. Severe anemia developed after a few phlebotomies, and she was also found to have congenital dyserythropoietic anemia that, though not completely typical, resembled type II. Only genetic testing allowed the definition of the coexistence of the 2 diseases, both responsible for the iron overload. This report points out the need to consider congenital dyserythropoietic anemia in patients with hemochromatosis and unexplained macrocytosis and, conversely, to check for the presence of hereditary hemochromatosis in patients with congenital dyserythropoietic anemia and severe iron overload. To the authors' knowledge, this is the first report of homozygosity for the C282Y mutation of the HFE gene in a patient affected by congenital dyserythropoietic anemia.  (+info)

Bone marrow transplantation in a case of severe, type II congenital dyserythropoietic anaemia (CDA II). (5/81)

Type II congenital dyserythropoietic anaemia (CDA-II or HEMPAS) is an autosomal recessive disorder, representing the most frequent form of congenital dyserythropoiesis. It is characterised by normocytic anaemia, variable jaundice and hepato-splenomegaly. Gallbladder disease and secondary haemochromatosis are frequent complications. We report a case characterised by severe transfusion-dependent anaemia. The proband inherited CDA-II in association with beta-thalassaemia trait. Splenectomy did not abolish the transfusion dependence and this, in association with poor compliance to iron-chelation therapy, prompted us to consider bone marrow transplantation (BMT) from his HLA-identical sibling. The preparative regimen included busulfan, thiotepa and fludarabine, and graft-versus-host disease prophylaxis consisted of cyclosporin A and short-term methotrexate. Engraftment of donor cells was prompt and the post-transplant course uncomplicated. The patient is alive and transfusion-independent 36 months after allograft. This is the first case of severe CDA-II to undergo BMT. Analysis of this pedigree suggests that interaction with beta-thalassaemia enhanced the clinical severity of CDA-II, making BMT an attractive therapy for patients with transfusion dependence.  (+info)

Glycophorin A in two patients with congenital dyserythropoietic anemia type I and type II is partly unglycosylated. (6/81)

Glycophorins A from erythrocyte membranes of two patients with congenital dyserythropoietic anemia type I and type II (CDA type I and II) were analyzed for carbohydrate molar composition employing a modification of the recently published method that allowed simultaneous determination of carbohydrates and protein in electrophoretic bands of glycoproteins separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (Zdebska & Koscielak, 1999, Anal Biochem., 275, 171-179). The modification involved a preliminary extraction of erythrocyte membranes with aqueous phenol, subsequent electrophoresis and analysis of the extracted glycophorins rather than electrophoresis and analysis of the glycophorin from intact erythrocyte membranes. The results showed a large deficit of N-acetylgalactosamine, galactose, and sialic acid residues in glycophorin A from patients with CDA type I and type II amounting to about 45% and 55%, respectively. The results strongly suggest that glycophorin A in these patients is partly unglycosylated with respect to O-linked glycans. In addition, glycophorin A from erythrocytes of a patient with CDA II but not CDA I exhibited a significant deficit of mannose and N-acetylglucosamine suggesting that its N-glycosylation site was also partly unglycosylated.  (+info)

Natural history of congenital dyserythropoietic anemia type II. (7/81)

Congenital dyserythropoietic anemia type II (CDA-II) is an autosomal recessive disease characterized by anemia, jaundice, splenomegaly, and erythroblast multinuclearity. The natural history of the disease is unknown. The frequency, the relevance of complications, and the use of splenectomy are poorly defined. This study examined 98 patients from unrelated families enrolled in the International Registry of CDA-II. Retrospective data were obtained using an appropriate questionnaire. The mean age at presentation was 5.2 +/- 6.1 years. Anemia was present in 66% and jaundice in 53.4% of cases. The mean age at correct diagnosis was 15.9 +/- 11.8 years. Twenty-three percent of patients for whom data were available developed anemia during the neonatal period, and 10 of these individuals required transfusions. Splenectomy produced an increased hemoglobin (P <.001) and a reduced bilirubin level (P =.007) in comparison with values before splenectomy. Preliminary data indicate that iron overload occurs irrespective of the hemochromatosis genotype. (Blood. 2001;98:1258-1260)  (+info)

Different substitutions at residue D218 of the X-linked transcription factor GATA1 lead to altered clinical severity of macrothrombocytopenia and anemia and are associated with variable skewed X inactivation. (8/81)

GATA1 is the X-linked transcriptional activator required for megakaryocyte and erythrocyte differentiation. Missense mutations in the N-terminal zinc finger (Nf) of GATA1 result in abnormal hematopoiesis, as documented in four families: the mutation V205M leads to both severe macrothrombocytopenia and dyserythropoietic anemia, D218G to macrothrombocytopenia and mild dyserythropoiesis without anemia, G208S to macrothrombocytopenia and R216Q to macrothrombocytopenia with beta-thalassemia. The three first GATA1 mutants display a disturbed binding to their essential transcription cofactor FOG1, whereas the fourth mutant shows an abnormal direct DNA binding. In this study, we describe a new family with deep macrothrombocytopenia, marked anemia and early mortality, if untreated, due to a different GATA1 mutation (D218Y) in the same residue 218 also implicated in the above mentioned milder phenotype. Zinc finger interaction studies revealed a stronger loss of affinity of D218Y-GATA1 than of D218G-GATA1 for FOG1 and a disturbed GATA1 self-association. Comparison of the phenotypic characteristics of patients from both families revealed that platelet and erythrocyte morphology as well as expression levels of the platelet GATA1-target gene products were more profoundly disturbed for the hemizygote D218Y mutation. The D218Y allele (as opposed to the D218G allele) was not expressed in the platelets of a female carrier while her leukocytes showed a skewed X-inactivation pattern. We conclude that the nature of the amino acid substitution at position 218 of the Nf of GATA1 is of crucial importance in determining the severity of the phenotype in X-linked macrothrombocytopenia patients and possibly also in inducing skewed X inactivation.  (+info)

The Online Mendelian Inheritance in Man (OMIM) compendium of human genes and genetic phenotypes includes three types of congenital dyserythropoietic anemia as reported in Table 1. A comprehensive overview of these disorders has been published recently.1. Congenital dyserythropoietic anemia type II is the most common of these inherited disorders. Typical morphological abnormalities of this condition are shown in Figure 1: these abnormalities clearly indicate that incomplete cytokinesis is one of the key features of erythroid cells in this condition.. More than 30 years ago, we investigated the pathophysiology of anemia in patients with congenital dyserythropoietic anemia type II in studies of iron kinetics.2 A wide variation in effectiveness of erythroid activity was observed, and a significant inverse relationship was found between ineffective erythropoiesis and peripheral hemolysis. In 4 patients with prominent peripheral hemolysis, splenectomy was carried out. Marked improvement in their ...
The congenital dyserythropoietic anemias are a heterogeneous group of rare disorders primarily affecting erythropoiesis with characteristic morphological abnormalities and a block in erythroid maturation. Mutations in the CDAN1 gene, which encodes Codanin-1, underlie the majority of congenital dyserythropoietic anemia type I cases. However, no likely pathogenic CDAN1 mutation has been detected in approximately 20% of cases, suggesting the presence of at least one other locus. We used whole genome sequencing and segregation analysis to identify a homozygous T to A transversion (c.533T|A), predicted to lead to a p.L178Q missense substitution in C15ORF41, a gene of unknown function, in a consanguineous pedigree of Middle-Eastern origin. Sequencing C15ORF41 in other CDAN1 mutation-negative congenital dyserythropoietic anemia type I pedigrees identified a homozygous transition (c.281A|G), predicted to lead to a p.Y94C substitution, in two further pedigrees of SouthEast Asian origin.

Congenital dyserythropoietic anemia type II (CDA II), or hereditary erythroblastic multinuclearity with positive acidified serum lysis test (HEMPAS) is a rare genetic anemia in humans characterized by hereditary erythroblastic multinuclearity with positive acidified serum lysis test. CDA type II is caused by mutations in the SEC23B gene. This gene provides instructions for making a protein that is involved in the transport of other proteins within cells. During the development of red blood cells, this protein may help ensure that proteins are transported to the areas where they are needed. Researchers are working to determine how mutations in the SEC23B gene lead to the signs and symptoms of CDA type II. Analyses of CDA II erythrocyte membranes showed that the band 3 glycoprotein is underglycosylated. An aberrant glycosylation pattern is seen in the polylactosamine carbohydrates which are normally attached to the band 3 and band 4.5 glycoproteins. The polylactosamines are, however, accumulated ...

Congenital dyserythropoietic anemia (CDA) is a rare blood disorder, similar to the thalassemias. CDA is one of many types of anemia, characterized by ineffective erythropoiesis, and resulting from a decrease in the number of red blood cells (RBCs) in the body and a less than normal quantity of hemoglobin in the blood. The symptoms and signs of congenital dyserythropoietic anemia are consistent with: Tiredness (fatigue) Weakness Pale skin CDA may be transmitted by both parents autosomal recessively or dominantly and has four different subtypes, CDA Type I, CDA Type II, CDA Type III, and CDA Type IV . CDA type II (CDA II) is the most frequent type of congenital dyserythropoietic anemias. More than 300 cases have been described, but with the exception of a report by the International CDA II Registry, these reports include only small numbers of cases and no data on the lifetime evolution of the disease. The diagnosis of congenital dyserythropoietic anemia can be done via sequence analysis of the ...
Congenital dyserythropoietic anemia (CDA) is a rare group of red blood cell disorders characterized by ineffective erythropoiesis and increased iron absorption. To determine whether growth differentation factor 15 (GDF15) hyper-expression is associated with the ineffective erythropoiesis and iron-loading complications of CDA type I (CDA I), GDF15 levels and other markers of erythropoiesis and iron overload were studied in blood from 17 CDA I patients. Significantly higher levels of GDF15 were detected among the CDA I patients (10 239 +/- 3049 pg/mL) compared with healthy volunteers (269 +/- 238 pg/mL). In addition, GDF15 correlated significantly with several erythropoietic and iron parameters including Hepcidin-25, Ferritin, and Hepcidin-25/Ferritin ratios. These novel results suggest that CDA I patients express very high levels of serum GDF15, and that GDF15 contributes to the inappropriate suppression of hepcidin with subsequent secondary hemochromatosis ...

The clinical and haematological features of an unusual case of congenital dyserythropoietic anaemia are described. There was a pronounced haemolytic component to the anaemia, with a mean cell life of five days, and a remarkable response to splenectomy. Measurement of the incorporation of 15N glycine into the haem of circulating red cells and into bilirubin showed that haem turnover due to ineffective erythropoiesis was increased 45 times compared with a control group (11.63 mg/kg/day, NR = 0.26 + 0-10) and represented 51% of total erythroid haem turnover.. ...

Various inherited and acquired hematopoietic disorders are characterized by macrocytic anemia, in which red blood cells are abnormally large with insufficient hemoglobin, and evidence of dysfunctional erythropoiesis. While multiple etiologies have been implicated for the development of these disorders, many cases of abnormal blood cell production have no discernable cause. Vijay Sankaran and colleagues at Harvard Medical School identified a female with a macrocytic, dyserythropoietic anemia that had been present since childhood. Moreover, the mother and sister of the affected individual also presented with macrocytic anemia, suggesting an underlying genetic cause. Whole exome sequencing of the three affected family members and one unaffected member revealed the presence of a mutation in one allele of the X-chromosomal gene aminolevulinic acid synthase (ALAS2), which encodes an erythroid-specific mitochondrial enzyme required for heme biosynthesis. Enzyme kinetic analysis of WT and mutant ALAS2 ...

Anemia symptoms depend on the cause, and can vary from person to person, but symptoms and signs may include fatigue, pale skin, heart palpitations, shortness of breath, and dizziness. There are several different types of anemia. Treatment depends upon the type.
The pathophysiology of the thalassemias can be traced to the deleterious effects of the globin-chain subunits that are produced in excess. In β-thalassemia, excess α chains cause damage to the red cell precursors and red cells and lead to profound anemia. This causes expansion of the ineffective marrow, with severe effects on development, bone formation, and growth. The major cause of morbidity and mortality is the effect of iron deposition in the endocrine organs, liver, and heart, which results from increased intestinal absorption and the effects of blood transfusion. The pathophysiology of the α-thalassemias is different because the excess β chains that result from defective α-chain production form β4 molecules, or hemoglobin H, which is soluble and does not precipitate in the marrow. However, it is unstable and precipitates in older red cells. Hence, the anemia of α-thalassemia is hemolytic rather than dyserythropoietic. ...

Congenital dyserythropoietic anemia (CDA) is an inherited blood disorder that affects the development of red blood cells. This disorder is one of many types of anemia, which is a condition characterized by a shortage of red blood cells. This shortage prevents the blood from carrying an adequate supply of oxygen to the bodys tissues. The resulting symptoms can include tiredness (fatigue), weakness, pale skin, and other complications.. Researchers have identified three major types of CDA: type I, type II, and type III. The types have different genetic causes and different but overlapping patterns of signs and symptoms.. CDA type I is characterized by moderate to severe anemia. It is usually diagnosed in childhood or adolescence, although in some cases, the condition can be detected before birth. Many affected individuals have yellowing of the skin and eyes (jaundice) and an enlarged liver and spleen (hepatosplenomegaly). This condition also causes the body to absorb too much iron, which builds up ...

A) Hemoglobin is a buffer B) Buffers can maintain pH by accepting protons C) Carbonic Acid can act as a buffer D) Buffers are only necessary in very few biological processes. Because many different non-bicarbonate buffers are present in human blood, the final equilibrium state reached at any given pCO 2 is highly complex and cannot be readily predicted using theory alone. Once the hemoglobin molecules reach the lungs, the reactions reverse. he buffer systems functioning in blood plasma include plasma proteins, phosphate, and bicarbonateand carbonic acid buffers. 0 0. The bicarbonate buffer is the primary buffering system of the IF surrounding the cells in tissues throughout the body. Get your answers by asking now. And the word buffer, in our everyday language, it refers to something that kind of smooths the impact of something, or it reduces the shock of something. This is responsible for about 80% of extracellular buffering. Introduction to pH and the pH scale. Anemia - Types with example, ...

Researchers from BRIC, University of Copenhagen, have just found a mechanism of the protein Codanin-1, shedding light on the blood disease CDAI. The findings contribute with important knowledge on how our DNA-stucture is maintained and how our genes are regulated.
Background: It is known that aurora B, a chromosomal passenger protein responsible for the proper progression of mitosis and cytokinesis, is overexpressed throughout the cell cycle in cancer cells. Overexpression of aurora B produced multinuclearity and induced aggressive metastasis, suggesting that overexpressed aurora B has multiple functions in cancer development. However, the detailed dynamics and functions of overexpressed aurora B are poorly understood. Results: We overexpressed GFP fused aurora B kinase in normal rat kidney epithelial cells. Using spinning disk confocal microscopy, we found that overexpressed aurora B-GFP was predominantly localized in the nucleus and along the cortex as a dot-like or short filamentous structure during interphase. Time-lapse imaging revealed that a cytoplasmic fraction of overexpressed aurora B-GFP was incorporated into the nucleus after cell division. Immunofluorescence showed that the nuclear fraction of overexpressed aurora B did not induce ectopic ...
Dr. Ans research is focused on developing a detailed molecular understanding of regulation of erythropoiesis. Her lab has developed methods to purify both human and mouse erythroid cells at distinct developmental stages and methods to quantify the progress of erythroid differentiation in vivo. Through RNA-seq analysis, her lab constructed global transcriptomesof human and murine erythroid cells. Based on the development of these novel methodology and database, Dr. Ans lab is currently working on three areas: 1) studying regulation of erythropoiesis by epigenetic modifiers such as methylcytosine dioxygenase TET2 and TET3; 2) Identifying the contribution of commonly mutated epigenetic modifiers to the dyserythropoiesis of myelodysplastic syndromes patients; 3) Improving red cell production ex vivo from stem cells.. ...

Refractory Anaemia (RA) is part of the heterogeneous group of diseases that affects normal blood cell production in the bone marrow and a category of myelodysplastic syndrome (MDS) . One example of RA is the 5q-syndrome. In RA, marrow blood cells fail to mature properly and are unable to work properly. They often die before they leave the marrow, or shortly after reaching the bloodstream (ineffective erythropoiesis or dyserythropoiesis). There are few data on the epidemiology of RA, which may account for 30-40% of all MDS cases. MDS is predominantly diagnosed in the elderly population. The global incidence of all MDS was comprised between 3,5 and 12,6 new cases / year / per 100,000 in some studies. ...
Herein, we demonstrated that TET2 expression increases during erytroid differentiation of primary hematopoietic progenitors from healthy donors and MDS patients. Pronier et al. [8] demonstrated that the TET2 silencing increased granulomonocytic differentiation in detriment of erythroid differentiation in normal CD34+ cells. Yan et al. [9], similarly demonstrated that TET2 inhibition led to MDS-like dyserythropoiesis. Of note, TET2 deletion leads to erythroid dysplasia and anemia in zebrafish model [14], suggesting a conserved function for TET2 in erythrocytes production.. Recently, Guo and colleagues [15] reported that TET2 mRNA levels was increased in mature erythroid cells from murine fetal liver, and in MEL and K562 cell lines upon chemically-induced erythroid differentiation. Using functional assays, the authors also established that TET2 plays a cytoprotective function in iron homeostasis against oxidative stress during erythropoiesis. In contrast, Inokura and colleagues [16], using cell ...

The pathogenesis of malaria remains unclear. It is characterized by increased RBC destruction, decreased RBC production, and bone marrow dyserythropoiesis typified by incomplete mitosis, multinucleation, chromatin disintegration, intercytoplasmic bridges, karyorrhexis, and distorted nuclei (reviewed in reference34). In addition, there is marked suppression of erythropoiesis, even in the presence of adequate functional erythropoietin production. Several alternative models have been proposed for the mechanism of anemia: sequestration of PRBC (2), rupture of PRBC during schizogony, macrophage-mediated ingestion of PRBC, bone marrow hypoxia due to blockage of microvasculature by PRBC, low iron availability, immune-mediated hemolysis mediated by RBC surface IgG and complement receptor C3 (1, 18, 38), disseminated intravascular coagulation (16, 20; H. A. Reid, letter, Lanceti:167-168, 1975), and decreased survivability of uninfected RBCs (23, 48). However, none of the above models adequately account ...
Mangalore is the gateway to Karnataka. It is one of the five talukas (other than Bantwal, Puttur, Sullia, Belthangady taluks) of the Dakshina Kannada District. This District formerly had 8 talukas, but these were split in August 1997 and the remaining talukas, namely Udupi, Kundapur and Karkala then formed a part of the Udupi district,but there is no division found in the living of two cities and it is still being recognised as avibhagitha (undivided) Dakshina Kannada.
