2. Figure 1
Methylation in gastric cancer. Methylation levels of 6 genes (MINT25, RORAa, GDNF, ADAM23, PRDM5, and MLF1) was measured by bisulfite pyrosequencing and normalized by the z score method. (A) Results of individual genes in the test set. (B) Results of individual genes in the validation set. EGC, early gastric cancer; AGC, advanced gastric cancer; GD, gastric dysplasia; NGM, nonneoplastic gastric mucosa; T, tumor tissue in patient with gastric cancer; ADJ, normal adjacent tissue to tumors; W, stomach wash sample in patient with gastric cancer; EN, stomach mucosal tissue in endoscopically normal patient; EW, stomach wash sample in endoscopically normal patient (*P < .05).

Receiver operating characteristic (ROC) curves for methylation-based detection of gastric cancer. The z score of DNA methylation in test (A) and validation (B) sets were plotted with the use of the top 4 candidate genes in each (test set: MINT25, RORAa, GDNF, ADAM23; validation set: MINT25, ADAM23, PRDM5, GDNF).
