Project description: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-enriched, cryopreserved diagnostic bone marrow samples were obtained from patients with newly diagnosed B-precursor acute lymphoblastic leukemia.
Project description:Proteogenomic analysis and genomic profiling, RNA-sequencing, and mass spectrometry-based analysis of High hyperdiploid childhood acute lymphoblastic leukemia.

Project description:Copy number and LOH analysis was performed for 304 casesof B-progenitor and T-lineage acute lymphoblastic leukemia. All caseswere genotyped with Affymetrix 250k Sty and Nsp arrays. 252 cases werealso genotyped with Hind and Xba arrays.

Project description:This comparative genomic hybridization (CGH) study investigated the effect of BCL6 on clonal evolution in BCR-ABL1-driven acute lymphoblastic leukemia (ALL). The frequencies of copy number alterations in BCR-ABL1-transformed BCL6+/+ and BCL6-/- leukemias were determined.
Project description:Chromosomal instability is a characteristic of cancer, in acute lymphoblastic leukemia, several genes with aberrations have been reported that are currently used as diagnostic tools, prognostics and are even part of the treatment. The CGH microarrays performed in ten adult individuals with ALL, and the JURKAT and CEM cell lines, show that there are regions of shared loss on chromosomes 2, 9 and 14 and of gain on chromosomes 13 and 17 that are maintained in more than five of the samples.
Project description:Methylation profiling can reveal patterns of hypermethlation and hypomethylation associated with distinct biologic subtypes of acute lymphoblastic leukemia (ALL). We performed methylation profiling of Down syndrome ALL cases and controls to identify unique biologic features of this ALL subgroup.
Project description: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.
Project description:This comparative genomic hybridization (CGH) study investigated the effect of BCL6 on clonal evolution in BCR-ABL1-driven acute lymphoblastic leukemia (ALL). The frequencies of copy number alterations in BCR-ABL1-transformed BCL6+/+ and BCL6-/- leukemias were determined. Three BCR-ABL1-transformed BCL6+/+ and BCL6-/- ALL samples derived from mice were maintained for 4 month in cell culture and were subjected to CGH analysis. As control samples, normal untransformed splenoytes were used.
