Affymetrix SNP 6.0 array data for human embryonic stem cell lines

Project description:Pluripotent human embryonic stem cells are studied for potential applications in regenerative cell replacement therapies because of their untransformed nature and unique capacity to self-renew and differentiate. However it is known that adaptation of hESCs occurs on prolonged culture and may be associated with the acquisition of chromosome abnormalities. We report a high resolution DNA SNP 6.0 array analysis showing copy number variation in 17 different hESC lines maintained in different laboratories. Several of the changes were culture induced and changed the expression levels of affected genes. Loss of heterozygosity (LOH) of chromosome 16q was detected in one line, in addition to several smaller LOH regions. Importantly, hESCs were found to contain several CNVs less than 3 Mb in size which is below the detection limit of conventional karyotyping.

Paired copy number analysis of DLBCL Diffuse Large B Cell Lymphoma [SNP 6.0 Array]

Project description:Copy number analysis can be useful for assessing prognosis in diffuse large B cell lymphoma (DLBCL). We analyzed copy number data from tumor samples of 60 patients diagnosed with DLBCL de novo and their matched normal samples. We detected a total of 63 recurrent copy number alterations (CNAs), including 33 gains, 30 losses, and nine recurrent acquired copy number neutral loss of heterozygosity (CNN-LOH). Interestingly, 20% of cases acquired CNN-LOH of 6p21 locus, which involves the HLA region. In normal cells there were no CNAs but we observed CNN-LOH involving some key lymphoma regions such as 6p21 and 9p24.1 (5%) and 17p13.1 (2.5%) in DLBCL patients. Furthermore, a model with some specific CNA was able to predict the subtype of DLBCL, 1p36.32 and 10q23.31 losses being restricted to germinal center B cell-like (GCB) DLBCL. In contrast, 8p23.3 losses and 11q24.3 gains were strongly associated with the non-GCB subtype. A poor prognosis was associated with biallelic inactivation of TP53 or 18p11.32 losses, while prognosis was better in cases carrying 11q24.3 gains, which includes ETS1 and FLI1 genes. In summary, CNA abnormalities identify specific DLBCL groups, and we describe CN-LOH in germline cells from DLBCL patients that are associated with genes that probably play a key role in DLBCL development.

Affymetrix SNP 6.0 array data for chordoma samples

Project description:Chordomas are rare, low to intermediate grade malignant bone tumors of the axial skeleton, believed to originate from the notochord. Treatment options are limited and mainly restricted to surgical excision, as chordomas have been proven to be largely resistant to conventional ionizing radiation and chemotherapy. Therefore a new cell line was established. The cell line has been characterized by immunohistochemistry,western blot and karyotyping using cobra fish technology. Copy number variations (CNV) and loss-of heterozygosity (LOH) from fibroblasts, tumor tissue, low and high cell line passage was evaluted by using Affymetrix 6.0SNP Arrays. DNA isolated from the patients MNCs was used as control. The cell line MUG-Chor1 is highly similar to genetic profiles of chordomas and provides therefore a powerful tool for further investigations.

Genotyping of human neuroblastoma tumors

Project description:Chromosome 1p LOH was seen in one-third of cases. LOH events on chromosomes 11q and 1p were generally accompanied by copy number loss. The one exception was on chromosome 11p, where LOH in all 4 cases was accompanied by normal copy number or diploidy, implying uniparental disomy. Amplification of MYCN was also noted, and also, amplification of a second gene, ALK, in a single case. Experiment Overall Design: We analyzed paired blood and primary tumor samples from 22 children with high-risk neuroblastoma for loss of heterozygosity (LOH) and DNA copy number change.
