Background and Aim: Angiogenesis is essential in the progression and metastasis of solid tumors. It has been proved that increase in angiogenesis within primary solid tumors is actually associated with nodal metastasis and risk prognosis of some malignancies. In contrast, regarding hematologic neoplasms very limited studies have been done. The goal of the present study was to determine MVD (M...
BACKGROUND Acute myeloid leukemia presenting the MYST3-CREBBP fusion gene is a rare subgroup associated with hemophagocytosis in early infancy and monocytic differentiation. The aim of this study was to define the relevant molecular cytogenetic characteristics of a unique series of early infancy acute myeloid leukemia cases (≤24months old), based on the presence of hemophagocytosis by blast cel...
regulation of normal cell growth and turnover is balanced between cell pro¬liferation, cell differentiation and apoptosis. a disruption of this balance is thought to be an important event leading to carcinogenesis .one of the effector molecules in apoptosis is fas antigen . cross-linking of fas by its ligand (fas l) or agonistic anti fas antibodies induces apoptosis of cells expressing fas on t...
Background:Brain and Acute Leukemia Cytoplasmic (BAALC) is a gene which its expression is confined to progenitor cells; therefore, no expression has been illustrated in mature cells of bone marrow or white blood cells (WBC). In addition, high BAALC expression is associated with poor prognosis in Acute Myeloid Leukemia (AML) individuals and is considered as an important risk factor in Cyto...
Background and Aims: DNA methyltransferase3A (DNMT3A) is necessary for the adjustment of gene expression, and the mutations in the DNMT3A gene are reported in a variety of leukemia cases. DNMT3A mutations are during cancer progression and cause poor prognosis in many leukemias. Thus, this gene can be a target for new treatments. This study aimed to examine the distribution of DNMT3A mutations i...
BACKGROUND Mixed phenotype acute leukemia (MPAL) represents a diagnostic and therapeutic dilemma. The European Group for the Immunological Classification of Leukemias (EGIL) scoring system unambiguously defines MPAL expressing aberrant lineage markers. Discussions surrounding it have focused on scoring details, and information is limited regarding its biological, clinical and prognostic signifi...
Advances in the molecular characterization of leukemic cells have greatly improved the precision of diagnosis and treatment assignment as well as the monitoring of residual disease in both acute lymphoblastic leukemia and acute myeloid leukemia. Currently, specific genetic rearrangements can be identified in as many as 50% of children with either acute lymphoblastic leukemia or acute myeloid le...
OBJECTIVE Acute mixed-lineage leukemia (AMLL) is characterized as the acute leukemia involved with acute myeloid cells and lymphoid cells at the same time. The AMLL is easily misdiagnosed because of a dual character involved with lymphoid and myeloid cells. At present, researches of AMLL in adults are more common. Only some are reported for children. Therefore, our aim was to study clinical cha...
The online version of this article has a Supplementary Appendix. Background Protein phosphatase 2A is a novel potential therapeutic target in several types of chronic and acute leukemia, and its inhibition is a common event in acute myeloid leukemia. Upregulation of SET is essential to inhibit protein phosphatase 2A in chronic myeloid leukemia, but its importance in acute myeloid leukemia has n...
Acute megakaryoblastic leukemia (AMKL) is a subtype of acute myeloid leukemia (AML) characterized by abnormal megakaryoblasts that expressplatelet-specific surfaceglycoprotein.Bonemarrowbiopsy frequently demonstrates extensive myelofibrosis, often making aspiration in these patients difficult. AMKL is extremely rare in adults, occurring in only 1% of AML patients. This is in contrast to childre...
