Project description:As a starting point of our integrative analysis, we performed a gene expression analysis to compare the transcriptome of UM models to normal choroidal melanocytes..
Project description:Affymetrix oligonucleotide microarrays were used to assess global differential gene expression comparing normal human melanocytes with six independent melanoma cell strains from advanced lesions. The data, validated at the protein level for selected genes, confirmed the overexpression in melanoma cells relative to normal melanocytes of several genes in the growth factor/receptor family that confer growth advantage and metastasis. In addition, novel pathways and patterns of associated expression in melanoma cells not reported before emerged. Keywords: class comparison study (melanoma vs melanocyte)
Project description:Spotted oligonucleotide microarrays were used to assess global differential gene expression comparing normal human melanocytes with six independent melanoma cell strains from advanced lesions. The data, validated at the protein level for selected genes, confirmed the overexpression in melanoma cells relative to normal melanocytes of several genes in the growth factor/receptor family that confer growth advantage and metastasis.

Project description:Malignant melanoma (MM) is a highly malignant tumor with poor prognosis. However, the molecular mechanism of melanoma invasion and metastasis remains unclear. In the present study, we performed the profiling of circRNA expression in normal melanocytes and melanoma cells with different invasive abilities using circRNA microarray analysis.

Project description:In order to address epigenetic regulation, NM and UM models were analyzed through OxBS sequencing pipeline (Cambridge Epigenetics). Whole genome DNA methylation analysis was carried out with a Cambridge Epigenetics kit (TrueMethyl kit) that corresponds to an oxidative bisulfite reaction, to identify and analyze only 5-methylcytosine (5-mC). This modification of bisulfite sequencing was found to be more robust in our samples, particularly for the normal melanocytes, most probably due to the abundance of melanin
Project description:Study the RNA expression differences in uveal melanoma cells and normal melanocytes, providing new insights into the tumorgenesis of uveal melanoma.
