The frequency and characteristics of childhood acute leukemia with a 14q32 translocation [other than the t(8;14)(q24;q32)] were determined in 335 cases of newly diagnosed acute lymphoblastic leukemia (ALL) and 105 cases of acute nonlymphoblastic leukemia (ANLL). Ten children, representing 2.3% of the entire cohort, had this abnormality (1.5% of ALL patients and 4.8% of ANLL patients). By French...

A new entity of acute leukemia coexpressing CD4(+)CD56(+) markers without any other lineage-specific markers has been identified recently as arising from lymphoid-related plasmacytoid dendritic cells (pDCs). In our laboratory, cells from a patient with such CD4(+)CD56(+) lineage-negative leukemia were unexpectedly found to also express the myeloid marker CD33. To confirm the diagnosis of pDC le...

Cancer stem cells (CSC) may provide the self-renewal capacity required to sustain a tumor. One possibility is that CSC arise from the stem cell counterparts in normal tissues. Alternatively, CSC may arise from more differentiated progenitor cells found in certain tissues. In support of this idea, we showed recently that mixed lineage leukemia fusion oncoproteins can convert committed hematopoie...

Hyperdiploidy (>50 chromosomes, or a DNA index >1.16) confers a favorable prognosis in B-lineage acute lymphoblastic leukemia of childhood. Children with B-lineage acute lymphoblastic leukemia whose lymphoblasts at diagnosis accumulate high levels of methotrexate (MTX) and MTX polyglutamates (MTXPGs) in vitro experience a better eventfree survival than those whose lymphoblasts do not (Blood 76:...

We performed polymerase chain reaction-variable number of tandem repeats analysis of flow-sorted peripheral blood T-, B-, natural killer-, and myeloid cell populations (van Leeuwen et al, Br J Haematol 79:218, 1991) in 32 children following allogeneic bone marrow transplantation (BMT) for leukemia to evaluate the relationship between mixed lymphoid chimerism and leukemia relapse. Five patients ...

The occurrence of leukemia in twins is rare but has a crucial implication in the genetic research of leukemia. This report presents 2 pairs of monozygotic twins with precursor B-cell acute lymphoblastic leukemia. Mixed lineage leukemia (MLL)-AF4 fusion genes were found in the twin sisters. This study is the first to report on infant ALL harboring the 46,XY, -4, +10, -13, del(14)(q24), -15, +2ma...

A gradual restriction in lineage potential of multipotent stem/progenitor cells is a hallmark of adult hematopoiesis, but the underlying molecular events governing these processes remain incompletely understood. Here, we identified robust expression of the leukemia-associated transcription factor hepatic leukemia factor (Hlf) in normal multipotent hematopoietic progenitors, which was rapidly do...

The nature of hemopoietic progenitors subject to leukemic transformation in acute myeloid leukemia (AML) has not been clearly defined. To address this issue, we have used DNase I hypersensitivity assays to study the chromatin structure surrounding the T-lineage-affiliated CD2 gene in the acute promyelocytic subtype of AML (APL). Upstream and downstream flanking regions of CD2 were found to be h...

Most mammalian transcription factors (TFs) and cofactors occupy thousands of genomic sites and modulate the expression of large gene networks to implement their biological functions. In this study, we describe an exception to this paradigm. TRIM33 is identified here as a lineage dependency in B cell neoplasms and is shown to perform this essential function by associating with a single cis eleme...
