We performed fluorescence in situ hybridization (FISH) for an MLL split signal on 223 adult T-ALL samples obtained within the framework of the German Multicenter ALL 07/2003 therapy trial.
Here we show that depending on extrinsic cues, human neonatal CD34(+) cells are readily immortalized along either the myeloid or lymphoid lineage upon MLL-AF9 expression and give rise to mainly lymphoid leukemia in immunocompromised mice.
Therapy-related B-lymphoblastic leukemia associated with Philadelphia chromosome and MLL rearrangement: Single institution experience and the review of the literature.
Translocations and amplifications of the mixed lineage leukemia-1 (MLL1) gene are associated with aggressive myeloid and lymphocytic leukemias in humans.
Chromosomal translocations of the Mixed-lineage leukemia 1 (<i>MLL1</i>) gene generate MLL chimeras that drive the pathogenesis of acute myeloid and lymphoid leukemia.
Except for one case with biallelic KMT2A (MLL) breaks, all cases analyzed by FISH lacked the most common translocations defining molecular subsets of lymphoblastic leukemia/lymphomas.
Therapy-related B lymphoblastic leukemia with t(4;11)(q21;q23)/AF4-MLL in a patient with mantle cell lymphoma after recent aggressive chemotherapy: a unique case report.
Using a combination of human B lymphoid leukemia cells and mouse models, we now show that AID expression can be harnessed for antileukemic effect, after inhibition of the RAD51 homologous recombination (HR) factor with 4,4'-diisothiocyanatostilbene-2-2'-disulfonic acid (DIDS).
SUMO1 negatively regulates the transcriptional activity of EVI1 and significantly increases its co-localization with EVI1 after treatment with arsenic trioxide.
Our Southern blot analyses of a large series of 313 acute leukemias with a specific tal-1 deletion probe (SILDB) demonstrated that tal-1 deletions exclusively occur in T-cell acute lymphoblastic leukemia (T-ALL) and not in precursor B-ALL or acute non-lymphocytic leukemias.
The most common recurrent cytogenetic abnormalities in T-lymphoblastic leukemia (T-acute lymphoblastic leukemia [T-ALL]) involve T-cell receptor (TCR) loci and a variety of partner genes, including HOX11, HOX11L2, MYC, and TAL1.
