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:Purpose: Epigenetic mechanisms and alterations in uveal melanoma (UM) development are still not well understood. In this pilot study, histone posttranslational modifications (PTMs), which are epigenetic mechanisms regulating gene expression, were analyzed in UM formalin-fixed paraffin-embedded (FFPE) tissues and control tissue as well as in UM cell lines and healthy melanocytes to provide a deeper insight into the pathogenesis of UM and the potentially prognostic relevance of these molecular markers. Methods: FFPE tissue of UM (n=24) and normal choroid (n=4) as well as human UM cell lines (n=7), human skin melanocytes (n=6) and uveal melanocytes (n=2), were analyzed by a quantitative mass spectrometry (MS) approach.
Project description:Study the RNA expression differences in uveal melanoma cells and normal melanocytes, providing new insights into the tumorgenesis of uveal melanoma.
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.
