Comparison of positive rates of CpG, TpG, TpA (deamination on the antisense strand), and other kinds of mutations at each CpG site between 4 normal gastric biopsies (Normal) and 5 pairs of gastric carcinoma tissues (GC) and the corresponding normal tissues (GC-Nor) (mean ± SD, %). This evidence concerns the gene PLAT and gastric carcinoma.
