| Research Abstract |
We investigated methylation of malignant pheochromocytoma (PCC) and paraganglioma (PGL) tumors. We performed Infinium HumanMethylation450 Bead Chip array, which covers 485,577 CpG sites using DNA samples extracted from resected PCC/PGL tissues.
From the results of the Bead Chip array, we selected 12 CpG sites as hypermethylated and 16 CpG sites as hypomethylated candidates. Successively performed semiquantitative methylation-PCR revealed that, of the 28, three CpG sites were selected as possible epigenomic contributors to canceration of PCC/PGL. (one hypermethylated (cg02119938) and two hypomethylated sites (cg16918905, cg26870725). ) The cg02119938 is related to ACSBG1 (acyl-CoA synthetase bubblegum family member 1) gene, and cg26870725 is related to the MAST1 (microtubule associated serine-threonine kinase 1) gene. We showed here three possible CpG sites, in which aberrant promoter methylation/demethylation might be involved in silencing/expressing of cancer-related genes.
