Genotyping of human basal cell carcinomas unveils uniparental disomy as a key domatic event.

ABSTRACT: 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. Experiment Overall Design: 14 BCC/Blood pairs were used in this study to obtain genome-wide SNP profiles. By comparing tumour and blood DNA, LOH for each SNP could be obtained. Signal intensity for each SNP were used to deternime CNA.

Basal cell carcinoma is the most common human cancer with increasing incidence reported worldwide. Despite the aberrant signaling role of the Hedgehog pathway, little is known about the genetic mechanisms underlying basal cell carcinomas. Towards a better understanding of global genetic events, we have employed the Affymetrix Mapping 10K single nucleotide polymorphism (SNP) microarray technique for "fingerprinting" genomewide allelic imbalance in 14 basal cell carcinoma-blood pair samples.

Prevalence of Copy-number neutral LOH in glioblastomas revealed by analysis of laser-microdissected tissues

Project description:We have employed a laser capture microdissection technique and single nucleotide polymorphism arrays to characterize genomic alterations associated with the development of glioblastomas. Combined analysis of LOH and copy number revealed that more than half of the identified 254 LOH loci showed no copy number alteration, indicating the presence of copy-number neutral LOH Keywords: DNA copy number, Loss of heterozygosity Affymetrix 50K SNP mapping arrays were used to profile 14 primary glioblastomas (GBMs) with matched blood DNA samples. Loss of heterozygosity (LOH) and copy number abnormality (CNA) profiles were derived from each tumour-blood pair.

Affymetrix SNP array data for pediatric acute myeloid leukemia (AML) samples at diagnosis: Xba SNP array

Project description:Genome-wide profiling of Copy Number Alterations (CNA) and Loss of Heterozygosity (LOH), gene expression and resequencing of pediatric AML. This study characterizes the CNA and LOH in a representative cross-section through subtypes of pediatric AML. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from cryopreserved diagnostic bone marrow or peripheral blood samples. 111 pediatric AML samples were studied using either Affymetrix 100K + 500K 5.0 SNP arrays, 65 of the samples had paired germ line material. The supplemental file 'GSE15732_AML_175_SNP_Xba_signal.txt' contains the raw signals generated by dChip without normalization. The CNA and LOH data can be found in the Supplemental Information of the associated manuscript.
