Aberrant promoter methylation and resultant silencing of TRAIL decoy receptors were reported in a variety of cancers, but to date little is known about the relevance of this epigenetic modification in melanoma. In this study, we examined the methylation and the expression status of TRAIL receptor genes in cutaneous and uveal melanoma cell lines and specimens and their interaction with DNA methyltransferases (DNMTs) DNMT1, DNMT3a, and DNMT3b. DR4 and DR5 methylation was not frequent in cutaneous melanoma but on the contrary it was very frequent in uveal melanoma.

We have recently reported that in astrocytoma cells the expression of interleukin-8 (IL-8) is upregulated by prostaglandin E2 (PGE2). Unfortunately, the exact mechanism by which this happens has not been clarified yet. Here, we have investigated whether IL-8 activation by PGE2 involves changes in DNA methylation and/or histone modifications in 46 astrocytoma specimens, two astrocytoma cell lines and normal astrocytic cells.
