T-cell acute lymphoblastic leukemia arises from the leukemic transformation of developing thymocytes and results from cooperative genetic lesions. Inactivation of the PHF6 gene is frequently observed in T-cell acute lymphoblastic leukemia, suggesting an important tumor suppressive role for PHF6 in the pathobiology of this leukemia. Although the precise function of PHF6 is still unknown, this ge...

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...

Effect of graft source on unrelated donor haemopoietic stem-cell trans-plantation in adults with acute leukaemia: a retrospective analysis. al. Unrelated transplantation for poor-prognosis adult acute lym-phoblastic leukemia: long-term outcome analysis and study of the impact of hematopoietic graft source. R, et al. Favorable outcome of unrelated cord blood transplantation for Philadelphia chro...

Background: Acute leukemia is one of the most common types of childhood malignancies and one fourth of malignancies in this age group is acute leukemia. Acute leukemia may be myeloid or lymphoid. Acute lymphoblastic leukemia is characterized with abnormal proliferation of lymphoid cells and symptoms related to this are acute and if disease is not treated appropriately, it progresses rapidly and...

The transcription factor Sox4 plays an indispensable role in the development of early progenitor B cells from hematopoietic stem cells. However, its role in B-cell acute lymphoblastic leukemia, a malignant counterpart of normal progenitor B cells, is not fully understood. Here we show that SOX4 is highly expressed in human acute lymphoblastic leukemia cells. To systematically study the function...

Background: Previous studies have pointed to the major role of viruses in pathogenesis cancers, especially lymphoproliferative cancers. Objectives: The current study investigated relationship between recent Human Herpesvirus Type 6 (HHV6) infection and childhood leukemia-lymphoma syndrome. Methods: From January 2011 December 2012, we entered every new case acute lymphoblastic leukemia, non-Hodg...

The ex vivo sensitivity of pediatric leukemia cells to the proteasome inhibitor bortezomib was compared to 3 next generation proteasome inhibitors: the epoxyketone-based irreversible proteasome inhibitors carfilzomib, its orally bio-available analog ONX 0912, and the immunoproteasome inhibitor ONX 0914. LC50 values were determined by MTT cytotoxicity assays for 29 childhood acute lymphoblastic ...

Herein, we present a rare case of acute myeloid leukemia (AML) with CBFA2T3-rearrangement and the expression megakaryocytic lymphoid markers, highlighting need for high suspicion index in differential diagnosis applying adequate workup to avoid misdiagnosing this entity. CBFA2T3::GLIS2-positive AML is primarily found infants non-down syndrome megakaryoblastic (non-DSAMKL). Flow cytometry immuno...

fms-like tyrosine kinase-3 is a receptor tyrosine kinase expressed by immature hematopoietic cells and is important for the normal development of stem cells and the immune system. mutations of fms-like tyrosine kinase-3 have been detected in about 30% of patients with acute myelogenous leukemia and a small number of patients with acute lymphoblastic leukemia. the fms-like tyrosine kinase-3 muta...

Abstract Background Leukemia is the most prevalent childhood cancer, and Acute Lymphoblastic Leukemia (ALL) constitutes 75% of all cases. Some epidemiological studies have shown a relationship between socioeconomic status (SES) and some childhood cancers. In the present study, an attempt was made to assess socioeconomical status in a case-control study. Materials and Methods In 2010, a c...
