When comparing gastric normal and tumor samples, of all 28 genes, 6 were significant below p < 0.01 and had a fold change increase over 1.5 (BIRC5, CTNNB1, HER2, MET, PECAM-1 and uPAR) while only one gene had a 1.5-fold change reduction at the same significance (MMP- 2). This evidence concerns the gene CTNNB1 and neoplasm.
