Clinical significance of recurrent copy number abnormalities revealed by SNP array in childhood T-cell acute lymphoblastic leukemia

ABSTRACT: T-cell acute lymphoblastic leukemia (T-ALL) is a genetically highly heterogeneous disease, and numerous genetic aberrations in the leukemic genome are responsible for the biological and clinical differences among particular ALL subtypes. However, there is limited knowledge about the association of whole genome copy number abnormalities (CNAs) in childhood T-cell ALL with the course of leukemia and outcome. The aim of study was identification the pattern of whole genome CNAs in 86 newly diagnosed childhood T-ALL using a high-density single-nucleotide polymorphism (SNP) array.A series of bone marrow aspirates from 86 children with newly diagnosed T-ALL were analysed prior to any oncological treatment.

Copy-number alterations correlate to high-risk genomic aberrations and survival in chronic lymphocytic leukemia

Project description:Large but not small copy-number alterations correlate to high-risk genomic aberrations and survival in chronic lymphocytic leukemia: a high-resolution genomic screening of newly diagnosed patients. Single nucleotide polymorphism (SNP)-arrays allow simultaneous detection of copy-number aberrations (CNAs) and copy-number neutral loss-of-heterozygosity (CNN-LOH). In this study we investigated the presence of CNAs and CNN-LOH in newly diagnosed CLL samples from a Swedish chronic lymphocytic leukemia (CLL) cohort. In this study we could detect the known recurrent aberrations in CLL (i.e. deletions of 13q, 11q, 17p and trisomy 12). We also detected other both large and small CNAs which were mostly non-recurrent. CNN-LOH was detected on chromosome 13q in patients that carried homozygous deletion of 13q.

Genome-wide profiling of endothelial progenitor cells in multiple myeloma

Project description:In multiple myeloma (MM), endothelial progenitor cells (EPCs) regulate tumor angiogenesis and disease progression. EPCs from 20 newly diagnosed patients with advanced MM were examined for genomic instability by RNA microarrays to assess changes in gene expression. EPCs were derived from single-cell suspensions of bone marrow (BM) aspirates from newly diagnosed MM patients, and RNA was extracted for microarray hybridization.

Genome-wide profiling of tumor cells in multiple myeloma

Project description:In multiple myeloma (MM), endothelial progenitor cells (EPCs) regulate tumor angiogenesis and disease progression. They share a common bone marrow microenvironment with myeloma tumor cells. CD138+ tumor plasma cells from 12 newly diagnosed patients with advanced MM were examined for genomic instability by RNA microarrays to assess changes in gene expression. Tumor cells were derived from single-cell suspensions of bone marrow (BM) aspirates from newly diagnosed MM patients, and RNA was extracted for microarray hybridization.

Genome-wide array comparative genomic hybridization (aCGH) profiling of endothelial progenitor cells, and their comparison to tumor plasma cells, in multiple myeloma

Project description:In multiple myeloma (MM), endothelial progenitor cells (EPCs) regulate tumor angiogenesis and disease progression. EPCs from 16 newly diagnosed patients with advanced MM were examined for genomic instability by aCGH to assess chromosomal gains and losses. Data were compared to aCGH results from corresponding CD138+ tumor plasma cells from these patients. EPCs and tumor cells were derived from single-cell suspensions of bone marrow (BM) aspirates from newly diagnosed MM patients, and total genomic DNA was extracted for aCGH. DNA from healthy male peripheral blood mononuclear cells (PBMCs; Promega, Madison, WI) was used as the normal control DNA.
