Chromosomal rearrangements deregulating hematopoietic transcription factors are common in acute lymphoblastic leukemia (ALL). Here we show that deregulation of the homeobox transcription factor gene DUX4 and the ETS transcription factor gene ERG is a hallmark of a subtype of B-progenitor ALL that comprises up to 7% of B-ALL. DUX4 rearrangement and overexpression was present in all cases and was accompanied by transcriptional deregulation of ERG, expression of a novel ERG isoform, ERGalt, and frequent ERG deletion...

Williams syndrome (WBS) is a rare neurodevelopmental disorder with specific phenotypic characteristics and cardiac abnormalities, but is not considered as a cancer predisposing condition. However, in rare cases, malignancies have been described in patients with WBS, with hematologic cancer (mainly Burkitt Lymphoma and Acute Lymphoblastic Leukemia) as the most represented. We report here the case of a boy with WS and B-NHL. This is the unique case within the large cohort of patients (n = 117) followed in our institution for long time (mean clinical follow-up, 13 years)...

Thiopurine-related hematotoxicity in paediatric acute lymphoblastic leukemia (ALL) and inflammatory bowel diseases has been linked to genetically defined variability in thiopurine S-methyltransferase (TPMT) activity. While gene testing of TPMT is being clinically implemented, it is unclear if additional genetic variation influences TPMT activity with consequences for thiopurine-related toxicity. To examine this possibility, we performed a genome-wide association study (GWAS) of red blood cell TPMT activity in 844 Estonian individuals and 245 paediatric ALL-cases...

Central nervous system acute lymphoblastic leukaemia (CNS-ALL) is a major clinical problem. CNS-directed 'prophylactic' chemo- or radio - therapy is associated with significant early and long-term toxicity. Moreover, greater than a third of the relapses occur in the CNS. To design specific, more effective and less toxic therapy and for personalized precise adjustment of prophylactic therapy there is a need for better understanding of the biology of this disease. Specifically, the precise neurotropic mechanisms of ALL are currently unclear, as is the pathogenesis of CNS relapse...

Objective: To investigate the association between parental environmental risk factors exposure and the risk for childhood acute lymphoblastic leukemia (ALL). Methods: A total of 179 ALL children cases were selected in Tianjin Blood Disease Hospital and 136 healthy children matched by age, gender and living place were selected in 2015 for a case control study. The data were analyzed with univariate and multivariate non conditional logistic regression models. Results: The results of multivariate logistic regression analysis indicated that sex, history of abortion, exposure in a smoking environment during pregnancy, catching a cold, taking antipyretic analgesics, maternal exposure to air purifying agent, father' s occupational exposure to petroleum products and home decoration during pregnancy were associated with the risk of childhood ALL (P<0...

A significant number of children with T-lineage acute lymphoblastic leukemia (T-ALL) fail to respond to therapy and experience early relapse. CD99 has been shown to be overexpressed on T-ALL cells and is considered to be a reliable detector of the disease. However, the relevance of CD99 overexpression in ALL has not been investigated in a functional context. The aim of this study was to investigate the functional capacity of CD99+ cells in childhood ALL and determine the suitability of CD99 as a therapeutic target...

PURPOSE: We aimed to determine whether diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) measurement can detect skull bone marrow infiltration in newly diagnosed acute lymphoblastic leukemia (ALL) children before therapy and normalization in complete remission after treatment. METHODS: Fifty-one newly diagnosed acute lymphoblastic leukemia (ALL) patients and 30 healthy age-matched subjects were included. Cranial magnetic resonance imaging (MRI) scans were reviewed, and skull marrow ADC values were compared before treatment and in complete remission after therapy...

BACKGROUND: The outcome of malignancies in low- and middle-income countries (LMICs) is hampered owing to numerous factors. Current protocols are complex, demanding supportive care, often not optimally available. We de-escalated the UKALL 2003 protocol to improve the outcome of acute lymphoblastic leukemia (ALL) at our center. METHODS: In 2007-2009, children were treated as per the UKALL 2003 protocol (protocol 1). In 2010 and 2011, a modified version of the UKALL 2003 (protocol 2) was followed...

BACKGROUND: Acute lymphoblastic leukemia (ALL) is aggressive cancer, especially in adults as only 20-40% is cured with current treatment regimens. OBJECTIVES: The aim of this study is to evaluate prognostic factors and their effects on survival in ALL patients in the Northeast of Iran. METHODS: In a descriptive and retrospective study from 2009 to 2015, 48 ALL patients referred to hematology-oncology clinic. Age, sex, fever, blood group, type of ALL and consumption of amphotericin B, forms of cytogenetic, survival in the patients, WBC, hemoglobin, and platelet were checked in the first referral for every patient...

We report a pediatric case of acute T-lymphoblastic leukemia (T-ALL) with NOTCH1(wt) , FBXW7(wt) , STIL/TAL1, and PTEN (exons 2, 3, 4, 5) monoallelic deletions, biallelic CDKN2A/B deletion, and a minor t(8;14)(q24;q11)-positive subclone. Undetectable by a flow cytometric minimal residual disease assay, the t(8;14)(q24;q11) subclone expanded as detected by fluorescence in situ hybridization from 5% at diagnosis to 26% before consolidation and 100% at relapse bearing a monoallelic deletion (exons 2, 3) with a new frameshift mutation of PTEN and the same set of remaining molecular alterations...

BACKGROUND: Sip1/Tuftelin Interacting Protein (STIP) is highly conserved from Caenorhabditis elegans to Homo sapiens and has essential biological functions. However, its function in leukemia remains unknown. METHODS: Clinic Samples and cell model were used in this article to investigate the expression of STIP in lymphoblastic leukemia. The functional research of STIP was performed in ARH-77 by siRNA transfection, Immunofluorescence, cell count, cell cycle analysis, quantitative real-time RT-PCR, Sub-cellular Fractionation assays, Immunoprecipitation and Western blotting...

Acute B lymphoblastic leukemia (B-ALL) is one of the most common types of childhood cancer worldwide and chemotherapy is the main treatment approach. Despite good response rates to chemotherapy regiments, many patients eventually relapse and minimal residual disease (MRD) is the leading risk factor for relapse. The evolution of leukemic clones during disease development and treatment may have clinical significance. In this study, we performed immunoglobulin heavy chain (IGH) repertoire high throughput sequencing (HTS) on the diagnostic and post-treatment samples of 51 pediatric B-ALL patients...

Marsdenia tenacissimae extraction (MTE) as a traditional Chinese herb has long been used to treat some diseases such as tumors in China. However, the potential effectiveness of MTE in leukemia has not yet been fully understood, and the related molecular mechanism is still unknown. In the present study, we aimed to evaluate the effects of MTE on the proliferation and apoptosis of Jurkat cells (T-ALL lines) and lymphocytes from T-ALL (T-cell acute lymphoblastic leukemia) patients. Firstly, CCK8 assays and flow cytometry assays revealed that MTE dose-dependently reduced the proliferation of Jurkat cells by arresting cell cycle at S phase...

BACKGROUND: Relapsed acute lymphoblastic leukemia (ALL) is one of the main causes of mortality in childhood malignancies. Previous genetic studies demonstrated that chemoresistant ALL is driven by activating mutations in NT5C2, the gene encoding cytosolic 5´-nucleotidase (cN-II). However, molecular mechanisms underlying this hyperactivation are still unknown. Here, we present kinetic and structural properties of cN-II variants that represent 75 % of mutated alleles in patients who experience relapsed ALL (R367Q, R238W and L375F)...

The inactivation of tumor suppressor genes located within 9p21 locus (CDKN2A, CDKN2B) occurs in up to 30% of children with B-cell precursor acute lymphoblastic leukemia (BCP-ALL), but its independent prognostic significance remains controversial. In order to investigate the prognostic impact of deletions and promoter methylation within 9p21, 641 children with newly diagnosed BCP-ALL using methylation specific multiplex ligation-dependent probe amplification (MS-MLPA) were investigated. A total of 169 (26.4%) microdeletions in 9p21 were detected, of which 71 were homozygous...
