Methylation analysis of Epstein-Barr virus-associated gastric cancer case

The comprehensive DNA methylation status of gastric cancer cells obtained from an advanced Epstein-Barr virus-associated gastric cancer case, in which complete response to S-1 plus cisplatin chemotherapy was achieved, was analyzed with DNA methylation microarray (Illumina Infinium MethylationEPIC BeadChip). DNA was extracted from metastatic lesion (lymph node). Bisulphite-converted DNA from one sample was hybridised to the Illumina Infinium MethylationEPIC BeadChip.
