MetabolomicsImpact of acute lymphoblastic leukemia induction therapy: findings from metabolomics on non-fasted plasma samples from a biorepository

INTRODUCTION: Acute lymphoblastic leukemia (ALL) is among the most common cancers in children. With improvements in combination chemotherapy regimens, the overall survival has increased to over 90%. However, the current challenge is to mitigate adverse events resulting from the c...

MetabolomicsGREM1 Deficiency induced Bone Marrow Adipose Niche promotes B-cell Acute Lymphoblastic Leukemia Disease Progression
Relapse and disease progression are the primary causes of treatment failure and subsequent mortality in children B-cell acute lymphocytic leukemia (B-ALL). At diagnosis and during treatment, the bone marrow adipose microenvironment is commonly observed in pediatric leukemia. However, the relationshi...

TranscriptomicsRearrangement of CRLF2 in B-progenitor and Down syndrome associated acute lymphoblastic leukemia
Chromosomal aneuploidy and translocations are hallmarks of acute lymphoblastic leukemia (ALL), but many patients lack a recurring chromosomal alteration. Here we report a recurring interstitial deletion of the pseudoautosomal region 1 of chromosomes X and Y in B-progenitor ALL that results in the ex...

TranscriptomicsDiscovery of novel recurrent mutations and rearrangements in early T-cell precursor acute lymphoblastic leukemia by whole genome sequencing
Early T-cell precursor acute lymphoblastic leukaemia (ETP ALL) is an aggressive malignancy of unknown genetic basis. We performed whole genome sequencing of tumour and normal DNA from 12 children with ETP ALL and assessed the frequency of somatic alterations in 52 ETP and 42 non-ETP T-ALL samples by...

TranscriptomicsExpression data from Down syndrome and non-Down syndrome pediatric acute lymphoblastic leukemia cases
Gene expression profiling (GEP) can reveal characteristic signatures associated with distinct biologic subtypes of acute lymphoblastic leukemia (ALL). We performed GEP on Down syndrome (DS) and comparison non-Down syndrome (NDS) ALL cases to identify biologic differences between these groups. Ficoll...

TranscriptomicsT cell acute leukaemia development and chemo-resistance are mediated by dynamic interactions with heterogeneous bone marrow microenvironments.
It is widely accepted that complex interactions between cancer cells and their surrounding microenvironment contribute to disease development, chemo-resistance and disease relapse. In light of this observed interdependency, novel therapeutic interventions that target specific cancer stroma cell line...

TranscriptomicsSNP data from Down syndrome and non-Down syndrome pediatric acute lymphoblastic leukemia cases and controls
SNP profiling can reveal copy number abnormalities and loss of heterozygosity associated with distinct biologic subtypes of acute lymphoblastic leukemia (ALL). We performed SNP profiling of Down syndrome ALL cases and controls to identify unique biologic features of this ALL subgroup. Ficoll-enriche...

TranscriptomicsGene Expression Profile of 53 human T-ALL samples collected in human clinical trial E2993 (Marks et al., 2009)
To analyze the prognostic relevance of transcriptional profiling in adult T-ALL, we analyzed a clinical series of 53 primary leukemia samples uniformly treated according to the ECOG E2993 protocol using gene expression oligonucleotide microarrays. Unsupervised analysis and consensus clustering of mi...

GenomicsNotch1-driven epigenetic changes in a mouse model of T cell Acute Lymphoblastic Leukemia (T-ALL)
T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we used a mouse model of T-ALL through the overexpression of the intarcellular transcriptionally active part of Notch1 (N1-IC). This model fait...
