PTP4A3, a Signal Molecule Deregulated in Uveal Melanoma Metastasis

Despite improvements in primary treatment protocols, more than 50% of the patients with uveal melanoma die of late-occurring metastases located in the liver. After diagnosis of metastases the average life expectancy is 6 months and no effective treatment is available at this stage of the disease. Transcriptome analysis linked to comparative genomic hybridization have been used for this particular melanoma to identify a set of genes linked to metastasis that may represent valuable future targets for specific treatments.
