Project description:Primary uveal melanomas show multiple genetic alterations. To determine mutational status of six human primary uveal melanomas, we performed whole exome sequencing (WES) and called Single Nucleotide Polimorphism (SNPs) to identify somatic mutations in these human primary uveal melanomas.
Project description:<p>Uveal melanoma (UM) is the most common primary cancer of the eye and frequently leads to metastatic death. Metastatic risk can be stratified into low, intermediate and high based on the presence of mutually exclusive mutations in EIF1AX, SF3B1 and BAP1, respectively. The purpose of this study was to comprehensively profile the genetic aberrations in a set of primary uveal melanomas using whole exome sequencing, as well as DNA methylation profiling of selected samples, to improve understanding of its pathogenesis.</p>
Project description:Genome wide DNA methylation profiling of primary uveal melanoma cells, normal uveal melanocytes, neural crest stem cells, embryonic stem cells and uveal melanoma cell lines. The Illumina Infinium 27k Human DNA methylation Beadchip Rev B was used to obtain DNA methylation profiles across approximately 27,000 CpGs in the samples. Samples included 58 primary UM, 3 NUM and NCSC controls and 2 cell lines. Bisulphite converted DNA from the 63 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip Rev B
Project description:G protein alpha q and 11 are mutated in 90% of uveal melanoma and they activate the MAPK pathway. Using expression microarray analysis, we identified a unique MEK dependent transcriptional signature with genes that are involved in proliferation and tumor cell invasion. Uveal melanoma cells were profiled on Illumina Human HT-12 arrays per manufacturer's instructions
Project description:G protein alpha q and 11 are mutated in 80% of uveal melanoma. We observed that treatment with the BRD4 inhibitor JQ1 resulted in different phenotypic responses in G-protein mutant uveal melanoma cell lines and wild type uveal melanoma cell lines. We used microarrarys to profile the gene expression changes occuring in wild type and mutant cell lines in response to treament with JQ1 Uveal melanoma cells were profiled in triplicate on Affymetrix Human Genome U133A 2.0 Array arrays per manufacturer's instructions

Project description:Karyotyping by SNP array of primary uveal melanoma samples, uveal melanoma cell lines and normal controls The Human660WQuad v1.0 DNA Analysis Bead Chip and kit were used for high resolution molecular karyotyping of DNA isolated from snap-frozen primary uveal melanoma tissue isolated from enucleated eyes.
