Project description:High resolution genome wide DNA analysis on a large panel of Human Embryonic stem cell lines reveals loss of heterozygosity and copy number variation changes associated with culture and affecting gene expression This SuperSeries is composed of the following subset Series: GSE15095: Exon arrays for human embryonic stem cells GSE15096: Affymetrix SNP 6.0 array data for human embryonic stem cell lines
Project description:Affymetrix 10K SNP mapping arrays were used to profile 14 basal cell carcinomas (BCCs) with matched blood DNA samples. Loss of heterozygosity (LOH) and copy number abnormality (CNA) profiles were derived from each tumour-blood pair. Keywords: Genomic DNA on Affymetrix 10K SNP array
Project description:Copy number profiling of 36 ovarian tumors on Affymetrix 100K SNP arrays Thirty-six ovarian tumors were profiled for copy-number alterations with the Affymetrix 100K Mapping Array. Copy number profiling of 36 ovarian tumors on Affymetrix 500K SNP arrays Sixteen ovary tumors were profiled for copy-number alterations with the high-resolution Affymetrix 500K Mapping Array.
Project description:Samples were used to study if genomic copy number variation changes detected with SNP 6.0 array would correlate with the expression level changes in human embryonic stem cells These samples were used as a portion of the study evaluating the genomic stability and its effects on human embryonic stem cells in prolonged culture.
Project description:DNA copy number alterations and mutations were characterised by bulk SNP anlaysis and exome sequencing (not sown here) in three acute lymphoblastic leukaemia samples and one establish cell line REH. Further single cell experiments of these cases investigated the mutation and copy number targets previously defined exploring the sub-clonal populations and phylogenic trees within each leukaemia. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from cryopreserved diagnostic bone marrow or peripheral blood samples.
Project description:The genomic loci with copy number alterations are known to harbor cancer genes. We investigated a comprehensive panel of gastric cancer cell lines for their genome-wide copy number alterations. Eighteen gastric cancer cell lines were profiled using Affymetrix 500K SNP arrays. For copy number calculation, seven independent normal blood samples were profiled together. The copy numbers were calculated genome-wide, in these cell lines with high resolution and reveal the cell line specific amplification and copy number changes.
