investigation of leptin, leukemia inhibitory factor (lif), and il-6 serum levels in myeloid leukemia
background: leptin has been implicated in the differentiation and proliferation of hematopoietic cells. leukemia inhibitory factor (lif) may play an important role, along with interleukin-6 (il-6) and granulocyte colony stimulating factor (g- csf), in the regulation of early hematopoietic stem cells. the aim of the study was to evaluate serum level of leptin, lif, and il-6 in myeloid leukemia p...
A simplified system for classification of aggregate incidence and growth pattern in the CFU-c (colony-forming units in culture) assay, allowing simple and reproducible interpretation of test results, was developed and applied to 552 bone marrow samples from 202 patients with acute leukemia. Ninety-six consecutive patients with acute nonlymphoblastic leukemia were studied at diagnosis. The micro...
BACKGROUND Prognostic risk stratification according to acquired or inherited genetic alterations has received increasing attention in acute myeloid leukemia in recent years. A germline Janus kinase 2 haplotype designated as the 46/1 haplotype has been reported to be associated with an inherited predisposition to myeloproliferative neoplasms, and also to acute myeloid leukemia with normal karyot...
methotrexate is an anti-rheumatic agent used as a first-line tretment for rheumatoid arthritis. hematological malignancies like lymphoma or acute myeloid leukemia have been reported to be secondary to treatment with methotrexate, but are very uncommon. we report here the first moroccan case of ra patient on low dose mtx, who developed aml. we also reviewed all similar cases.
Early T precursor acute lymphoblastic leukemia (ETP ALL) is rare and has a characteristic phenotype. Mixed phenotype (MPAL), as per World Health Organization, needs to have two different lineages. On cytochemistry, myeloid lineage designated by more than 3% blast cells positivity for cytochemical myeloperoxidase (MPO). Flow cytometric analysis of MPO an arbitrary cutoff 10% been described in th...
Introduction: Apoptosis is an important mechanism in both physiological and pathological conditions. The BCL2 family of proteins plays a critical role in regulation of apoptotic cell death. Up and down regulation of BCL2-like 12 (BCL2L12), a new member of the BCL2 family, has been reported in several malignancies. However, the expression level of BCL2L12 rarely has been studied in leukemia. T...
Nitric oxide (NO) is a molecule required for many physiological functions, produced from L-arginine by NO synthases (NOS). It is a free radical, producing many reactive intermediates that account for its bioactivity. Sustained induction of the inducible form of NOS (iNOS) in chronic inflammation may be mutagenic, through NO-mediated DNA damage or hindrance to DNA repair, and thus potentially ca...
Although leukemia is the most common malignancy in childhood, congenital leukemia which manifests itself within the first 4 weeks of life is rare and accounts for less than 1% of all leukemias in childhood. Congenital leukemia should be differentiated from transient myeloproliferative disorder(TMD) which is noted in Down Syndrome. Among the reported patients, acute myeloid leukemia(AML) was...
PURPOSE Classification of acute leukemia is based on the commitment of leukemic cells to the myeloid or the lymphoid lineage. However, a small percentage of acute leukemia cases lack straightforward immunophenotypical lineage commitment. These leukemias of ambiguous lineage represent a heterogeneous category of acute leukemia that cannot be classified as either acute myeloid leukemia (AML) or a...
