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 T-cell lymphoblastic lymphoma comprises approximately 85-90% of all lymphoblastic lymphomas. It often arises as a mediastinal mass, and with bone marrow involvement. Presentation at other sites without nodal or mediastinal localization is uncommon. CASE REPORT We describe clinical, histologic, immunohistochemical, and molecular features of two cases of primary T-cell lymphoblastic ...
The relation between intrauterine growth and risk of childhood acute lymphoblastic leukemia was investigated in an Australian population-based case-control study that included 347 cases and 762 controls aged <15 years recruited from 2003 to 2006. Information on proportion of optimal birth weight, a measure of the appropriateness of fetal growth, was collected from mothers by questionnaire. Data...
BACKGROUND NOTCH1 mutations have been associated with a favorable outcome in pediatric acute T-lymphoblastic leukemia. However, the results of studies on the prognostic significance of NOTCH1 mutations in adult T-lymphoblastic leukemia remain controversial. DESIGN AND METHODS Here we have investigated the prognostic impact of mutations in the NOTCH1 pathway, in particular, the NOTCH1 and FBXW...
BACKGROUND The expression of HER2/neu in B-cell acute lymphoblastic leukemia has been reported in previous studies. OBJECTIVE The objective of this research was to study the expression of HER2/neu on the blasts of patients with acute leukemia from the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran. METHODS From June 2015 to February 2016, a HER2/neu monoclonal antibody ...
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...
BACKGROUND Cytokines released in the bone marrow and thymic microenvironments play a key role in the growth of T-cell acute lymphoblastic leukemia. Among such cytokines, interleukin-8 is highly expressed in T-cell acute lymphoblastic leukemia cells refractory to chemotherapy. In this study we explored whether bone marrow stromal cells can regulate IL-8 expression in T-cell acute lymphoblastic l...
INTRODUCTION Osteoporosis in children is rare and usually secondary to an underlying disease process whose diagnosis may be difficult to detect. Etiological factors responsible for osteoporosis secondary to chronic illness include immobility, pubertal delay and other hormonal disturbances. Rarely, it can be a manifestation of acute lymphoblastic leukemia. Most of the reported bone fracture inci...
Acute lymphoblastic leukemia is the most common malignancy in pediatric patients; its diagnosis is usually easy to establish as malignant lymphoblasts invade the bone marrow and peripheral blood. Some acute lymphoblastic leukemia patients may initially present with pancytopenia and a hypoplastic bone marrow leading to the initial diagnosis of aplastic anemia. In most of these patients clinical ...
