Evaluation of Formin Gene Status and Expression in Myeloproliferative and Myelodysplastic Disorders
Aim of the study is to analyze the expression of genes and sequences encoding the human mammalian diaphanous (mDia) related formin proteins to test the hypothesis that defects in the mDia expression or function might drive the pathophysiology of myelodysplastic syndrome, acute myeloid leukemia and other myeloproliferative diseases.
Leukocytes and myeloid lineage cells from these specimens will be assayed for expression of DRF genes using standard molecular biological approaches to measure mRNA levels. Extracted DNA will be analyzed for mutations that affect expressions or function using direct sequencing techniques.
Alternatively, expression of DRF gene products (mDia proteins) will be assessed using specific antibodies and flow cytometry. Molecular findings resulting from these assays will be correlated with clinical information recorded in specimen logbook.

Medical and Biotech [MESH] Definitions
Leukemia, Myelomonocytic, Juvenile
A leukemia affecting young children characterized by SPLENOMEGALY, enlarged lymph nodes, rashes, and hemorrhages. Traditionally classed as a myeloproliferative disease, it is now considered a mixed myeloproliferative-mylelodysplastic disorder.
Clonal myeloid disorders that possess both dysplastic and proliferative features but are not properly classified as either MYELODYSPLASTIC SYNDROMES or MYELOPROLIFERATIVE DISORDERS.
Leukemia, Erythroblastic, Acute
A myeloproliferative disorder characterized by neoplastic proliferation of erythroblastic and myeloblastic elements with atypical erythroblasts and myeloblasts in the peripheral blood.
Leukemia, Neutrophilic, Chronic
A rare myeloproliferative disorder that is characterized by a sustained, mature neutrophilic leukocytosis. No monocytosis, EOSINOPHILIA, or basophilia is present, nor is there a PHILADELPHIA CHROMOSOME or bcr-abl fusion gene (GENES, ABL).
Leukemia, Myeloid, Chronic, Atypical, Bcr-abl Negative
A myelodysplastic/myeloproliferative disorder characterized by myelodysplasia associated with bone marrow and peripheral blood patterns similar to CHRONIC MYELOID LEUKEMIA, but cytogenetically lacking a PHILADELPHIA CHROMOSOME or bcr/abl fusion gene (GENES, ABL).
The purpose of this study is to find out the safe dose range of the study drug in patients with myeloproliferative disorders.
Myelodysplastic and myeloproliferative Disease represent conditions with increased risk for pulmonary hypertension. However, the exact prevalence of pulmonary hypertension in these conditi...
Combination Chemotherapy and Antithymocyte Globulin in Reducing Graft-Versus-Host Disease in Patients Undergoing Donor Stem Cell Transplantation For Myelodysplastic Syndrome or Myeloproliferative Disorder
RATIONALE: Combining antithymocyte globulin with combination chemotherapy before donor peripheral stem cell transplantation may reduce the chance of developing graft-versus-host disease fo...
Chemotherapy, Stem Cell Transplantation, and Graft-Versus-Host-Disease Prevention in Treating Patients With Refractory or Relapsed Hematologic Cancer, Myelodysplastic Syndrome, or Myeloproliferative Disorder
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune...
RATIONALE: Giving chemotherapy drugs before a donor peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from...
ABSTRACT: INTRODUCTION: Transient myeloproliferative disorder is a hematologic abnormality characterized by an uncontrolled proliferation of myeloblasts in peripheral blood and bone marrow that primar...
The 8p11 myeloproliferative syndrome (EMS), also referred to as stem cell leukemia/lymphoma, is a chronic myeloproliferative disorder that rapidly progresses into acute leukemia. Molecularly, EMS is c...
Abstract The understanding of myeloproliferative neoplasms has changed dramatically since Dameshek proposed his classification over fifty years ago. Our knowledge of the types of cells which comprise...
To the Editor: Myeloproliferative neoplasms have an inherent tendency toward leukemic transformation. The genetic mechanisms of transformation remain largely unknown. We analyzed biopsy specimens of m...
Children with Noonan syndrome (NS) are at increased risk of developing juvenile myelomonocytic leukemia (JMML) or a myeloproliferative disorder associated with NS (MPD/NS) resembling JMML in the first...
