Leukemia is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells. These blood cells are not fully developed and are called blasts or leukemia cells. Symptoms may include bleeding and bruising, bone pain, fatigue, fever, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically made by blood tests or bone marrow biopsy.
Tumors of the hematopoietic and lymphoid tissues or tumours of the haematopoietic and lymphoid tissues are tumors that affect the blood, bone marrow, lymph, and lymphatic system. Because these tissues are all intimately connected through both the circulatory system and the immune system, a disease affecting one will often affect the others as well, making aplasia, myeloproliferation and lymphoproliferation closely related and often overlapping problems. While uncommon in solid tumors, chromosomal translocations are a common cause of these diseases. This commonly leads to a different approach in diagnosis and treatment of hematological malignancies. Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology. In some centers "hematology/oncology" is a single subspecialty of internal medicine while in others they are considered separate divisions. Not all hematological disorders are malignant ("cancerous"); these other blood conditions may also be managed by a hematologist.
Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with normal blood cell production. Symptoms may include feeling tired, shortness of breath, easy bruising and bleeding, and increased risk of infection. Occasionally, spread may occur to the brain, skin, or gums. As an acute leukemia, AML progresses rapidly, and is typically fatal within weeks or months if left untreated.
The Cancer Genome Project is part of the cancer, aging, and somatic mutation research based at the Wellcome Trust Sanger Institute in the United Kingdom. It aims to identify sequence variants/mutations critical in the development of human cancers. Like The Cancer Genome Atlas project within the United States, the Cancer Genome Project represents an effort in the War on Cancer to improve cancer diagnosis, treatment, and prevention through a better understanding of the molecular basis of the disease. The Cancer Genome Project was launched by Michael Stratton in 2000, and Peter Campbell is now the group leader of the project. The project works to combine knowledge of the human genome sequence with high throughput mutation detection techniques.
Cluster of differentiation antigen 135 (CD135) also known as fms like tyrosine kinase 3, receptor-type tyrosine-protein kinase FLT3, or fetal liver kinase-2 (Flk2) is a protein that in humans is encoded by the FLT3 gene. FLT3 is a cytokine receptor which belongs to the receptor tyrosine kinase class III. CD135 is the receptor for the cytokine Flt3 ligand (FLT3L).
MN1 is a gene found on human chromosome 22, with gene map locus 22q12.3-qter. Its official full name is meningioma 1 because it is disrupted by a balanced translocation (4;22) in a meningioma.
GATA2 or GATA-binding factor 2 is a transcription factor, i.e. a nuclear protein which regulates the expression of genes. It regulates many genes that are critical for the embryonic development, self-renewal, maintenance, and functionality of blood-forming, lympathic system-forming, and other tissue-forming stem cells. GATA2 is encoded by the GATA2 gene, a gene which often suffers germline and somatic mutations which lead to a wide range of familial and sporadic diseases, respectively. The gene and its product are targets for the treatment of these diseases.
CCAAT/enhancer-binding protein alpha is a protein encoded by the CEBPA gene in humans. CCAAT/enhancer-binding protein alpha is a transcription factor involved in the differentiation of certain blood cells. For details on the CCAAT structural motif in gene enhancers and on CCAAT/Enhancer Binding Proteins see the specific page.
Brian J. Druker is a physician-scientist at Oregon Health & Science University (OHSU), in Portland, Oregon. He is the director of OHSU's Knight Cancer Institute, JELD-WEN Chair of Leukemia Research, Associate Dean for Oncology in the OHSU School of Medicine, and professor of medicine.
Cancer genome sequencing is the whole genome sequencing of a single, homogeneous or heterogeneous group of cancer cells. It is a biochemical laboratory method for the characterization and identification of the DNA or RNA sequences of cancer cell(s).
Elaine R. Mardis is the co-executive director of the Institute for Genomic Medicine at Nationwide Children's Hospital, where she also serves as the Nationwide Foundation Endowed Chair in Genomic Medicine. She also is professor of pediatrics at the Ohio State University College of Medicine. Mardis’s research focuses on the genomic characterization of cancer and its implications for cancer medicine. She was part of the team that reported the first next-generation-based sequencing of a whole cancer genome, and participated extensively in The Cancer Genome Atlas (TCGA) and the Pediatric Cancer Genome Project (PCGP).
The Alvin J. Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine is a cancer treatment, research and education institution with six locations in the St. Louis area. Siteman is the only cancer center in Missouri and within 240 miles of St. Louis to be designated a Comprehensive Cancer Center by the National Cancer Institute (NCI). Siteman is also the only area member of the National Comprehensive Cancer Network, a nonprofit alliance of 32 cancer centers dedicated to improving the quality and effectiveness of cancer care.
Ten-eleven translocation methylcytosine dioxygenase 1 (TET1) is a member of the TET family of enzymes, in humans it is encoded by the TET1 gene. Its function, regulation, and utilizable pathways remain a matter of current research while it seems to be involved in DNA demethylation and therefore gene regulation.
AI-10-49 is a small molecule inhibitor of leukemic oncoprotein CBFβ-SMHHC developed by the laboratory of John Bushweller with efficacy demonstrated by the laboratories of Lucio H. Castilla and Monica Guzman. AI-10-49 allosterically binds to CBFβ-SMMHC and disrupts protein-protein interaction between CBFβ-SMMHC and tumor suppressor RUNX1. This inhibitor is under development as an anti-leukemic drug.
Christine J. Harrison is a Professor of Childhood Cancer Cytogenetics at Newcastle University. She works on acute leukemia and used cytogenetics to optimise treatment protocols.
James R. Downing is an American clinical executive. He is the president and chief executive officer of St. Jude Children's Research Hospital.
Scott Allen Armstrong is an American pediatric oncologist and cancer biologist focused on chromatin-based control of gene expression in cancer and therapeutic discovery. Armstrong and his team were the first to isolate rare leukemia stem cells in a mouse model of leukemia.
Brunangelo Falini is an Italian hematologist, academic and researcher. He is a Full Professor of Hematology, and Head of the Institute of Hematology and Bone Marrow Transplantation at University of Perugia.
Christopher Hourigan is a physician-scientist known for work on measurable residual disease in acute myeloid leukemia.
Bob Löwenberg is a clinical hematologist/investigator. He is Professor of Hematology at Erasmus University Rotterdam.
