| Research Abstract |
To find new neuroblastoma related genes, we investigated DNA methylation level and expression level of the tumor-related genes, which have been screened from global analysis of genome DNA and transcripts obtained from mouse skin cancers, in the neuroblastoma specimens. And then we examined the association between the aberrance of those genes and clinical data. In this study, we found that TFAP2E showed lower methylation level and higher expression level in the neuroblastoma samples compared to normal adrenal tissues. In addition, our data indicated that its expression was controlled by DNA methylation of CpG island-1. In the survival analysis, it was clearly shown that the lower methylation level of CpG island-1 was associated with the worse prognosis. Our present data strongly suggested that TFAP2E could be a new neuroblastoma related gene.
