Outline of Final Research Achievements |
Nasopharyngeal carcinoma (NPC) is a malignancy with poor prognosis that is endemic to Southern China. We investigated epigenetic alteration in NPC to find biomarker candidates for early detection. We obtained specimens from NPC patients and control subjects written informed consent. DNA and RNA were extracted and analyzed the differences in levels of DNA methylation and microRNA expression. We found promoter hypermethylation (UBE2L6, FSTL1, etc.) and dysregulation of microRNA (down-regulation of miR-497, up-regulation of ebv-miR-BART22, etc.). Furthermore, the concordant down-regulation of miR-497 in tissues and plasma suggested that miR-497 could be used as a diagnostic biomarker for NPC. Treatment with demethylation reagents and transfection of miR-497 mimic restored the gene expression levels, and inhibited cancer phenotypes (cell proliferation and migration and anti-apoptosis) in NPC.
